The Best Filtered Water Bottle for 2023

These bottles promise to remove any harmful substances, and keep your favorite beverages ice-cold all day!

filtered water bottle

Filtered water bottles are the ideal travel companion to ensure that you keep safely hydrated on any trip. Having access to clean water is crucial to avoiding the potentially fatal effects of dehydration, regardless of whether you’re traveling abroad, hiking in the mountains, or just going to your neighborhood gym.

Beyond just hydrating, filtered water bottles have other advantages. They provide peace of mind by ensuring you won’t risk getting sick from contaminated water. In the long run, they are less expensive and more environmentally friendly than single-use water bottles.

When selecting a filtered water bottle, it’s crucial to find a reputable and well-tested brand; otherwise, you risk significant health consequences. There are many options available that are effective, for sure, but they may lack reliability. This list will help you narrow down your options from among the many filtered water bottles that are now available to the best ones on the market.

How We Picked

  • Filtering Mechanism

    The best filtered water bottle on the market will even eliminate viruses, heavy metals, pesticides, and microplastics. Because of this, you can obtain drinkable water from any source, regardless of how filthy it is. Finding a filter with the highest level of filtration capability is crucial if you want to feel secure.

  • Taste

    The quality of good, filtered water should be a prime concern. Consider buying a filtered water bottle based on the taste (and odor) of the water it produces because it will remove nasty compounds like chlorine dioxide and heavy metals, which is perfect for filtering water that has already been deemed "safe."

  • Durability

    A filtered water bottle's construction material is important because it affects the bottle's durability and ergonomics. Hard, sturdy plastics are significantly more durable than soft plastics and stainless steel because your bottle will get some bumps and bruises along the journey.

  • Cost-Effectiveness

    Nobody in their right mind would want to spend a lot of money on a filtered water bottle that doesn't fulfill their demands, but choosing a cheap one would probably result in a low-quality item that lowers the quality of your filtered water, which eventually puts your health at risk.

Who This Is For

Anyone who wishes to improve their water quality with a functional, reliable solution, regardless of budgetary limitations. Whether going on a day trip, spending a few weeks in the backcountry, or even searching for a portable, daily solution to tap water toxins like lead and chlorine, having access to safe drinking water is one of the most important things you can do.

No matter where you obtain your water, you never know what you will get. While boiling water can help make it drinkable, doing so needs a lot of equipment, and carrying around huge amounts of clean water isn’t exactly practical, especially while on the move. That is why a filtered water bottle is essential if:

  • you go hiking, trekking, or on other outdoor trips
  • you visit other countries where you are unfamiliar with the water procedures, and it might be contaminated
  • you are concerned about tap water quality
  • you enjoy drinking bottled water but want to limit your plastic waste

Bottled water vs filtered water – what’s the difference?

Regular bottled water provides good and clean water, but you must bring many of them in your bag while going outdoors. However, filtered water bottles let you quickly filter any water source and are reusable. As a result, you only need to carry one empty filter bottle, saving up a lot of room and lighting your load.

When you’re ready to travel the world, there’s already a lot to put your money on. Using bottled water will be an expensive alternative because you will need to purchase many bottles. Contrarily, purchasing a single filter bottle will enable you to enjoy safe and clean water while saving you money that can be used to purchase other items.

Additionally, everything should be enjoyed, but not at the expense of damaging the environment or your health. Plastic water bottles used for everyday purposes cannot be reused. You put them in the garbage once you’re finished with them. As a result, there is an increase in plastic trash, which is terrible for the environment.

On the other hand, water bottles with filters are refillable, enabling you to use the same bottle in the long term by just replacing its filter. We know you don’t want to risk your safety to protect the environment. Rest assured because a filtering water bottle takes care of everything, stopping you from consuming dangerous germs or chemicals, and reducing the amount of trash that enters the environment.

Is it worth splurging on?

To put it short, spending more money on this kind of product is worthwhile as you are investing the money to guarantee that your water is safe to drink. Even while many tap and groundwater sources are entirely safe, consuming water from an unknown source is never worth the risk. Even though a water supply appears clean, it may include hazardous bacteria, viruses, protozoa, or other microscopic organisms that are invisible to human sight and make the water unfit for human use. And even with the Safe Drinking Water Act in place, tap water still has the potential to have toxins like lead, chlorine, arsenic, pesticides, and even bits from faulty wastewater treatment. In light of this, why not try a filtered water bottle instead? Filtered water is always healthier for you whether you intend to drink local municipal water or natural water from rivers, streams, lakes, and other sources.

Even if you have a particular location in mind, you may never be sure of the water’s purity. Whether you’re going to the gym, a distant area in Southeast Asia, or your office, the water from a spring or a tap, for instance, is bound to have chlorine at the very least in terms of flavor and odor. With a dependable water bottle equipped with a filter, you’ll never have to worry about water quality, bringing peace of mind and helping prevent health problems. Filtered water bottles can make any water drinkable by removing potentially dangerous chemicals, germs, viruses, and more. The price is reasonable. Instead, you stop spending as much money on bottled water. It is the most practical, easy-to-use, and environmentally responsible option compared to disinfection tables, UV light wands, hard pump filters, and boiling procedures.

Why You Should Trust Us

A consumer may find it overwhelming to choose the best-filtered water bottle from the wide selection offered online. There are several alternatives for filtered water bottles, many of which use marketing jargon to divert your attention. To relieve you of this load, we have thoroughly reviewed the essential end-user experiences. We’ve done extensive research to find the best-filtered water bottles for you out of the wide range of brands, filtration options, designs, and prices.

How We Picked

Nobody enjoys drinking water from a low-quality source with an unpleasant flavor, a slimy feeling, or both. As a result, when we listed our top recommendations of filtered water bottles, we strictly adhered to the criteria we had established for the filtered water bottle we reviewed. These included:

Filtering mechanism

To get the most use out of your filtered water bottle, choose a design with a long-lasting, high-quality water filter. Some water bottles use multiple-level filtering processes to eliminate dangerous microorganisms and purify the water. Others eradicate the mineral or chlorine flavor. If you’re only using the bottle to filter workplace tap water, certain more expensive filters, such as those meant to remove dirt from unclean lake water, are optional.

Most filters are made of activated carbon, which is a common substance. But there are significant differences in filtering levels. The longer you can use a filter before replacing it, the higher its quality must be. Search for a filter that can effectively remove impurities from water while also enhancing flavor and odor. The filter in your bottle should last for around two months on average. To benefit from drinking safe water from your bottle in the long run, you must regularly change your filter.

Taste

After filtration, water should be odorless, colorless, and, of course, tasteless. We chose filtered water bottles that can provide this level of quality.

Ease of use

A filtered water bottle should be simple to use. Some filtered bottles filter the water as you sip it through the straw, while another method pushes the liquid through the filter. Some bottles feature a typical opening that you must tilt to use, which is frequently more practical than a filter straw.

Ease of cleaning

If you wish your filtered water bottle to be used as long as possible, you must be able to frequently clean it to maintain it in excellent shape. Some water filtration bottles are simpler to clean than others; for added convenience, some may be put in the dishwasher. Before buying a product, you can read the reviews to see whether anyone has reported a cleaning or hygiene issue with the bottle.

Shape and size

Size and shape depend on your preferences and the kind of activity you’re undertaking. Filtered water bottles are available in various shapes and sizes, and your intended purpose will determine the best option for you. If you want to bring a water bottle with you on a trip abroad, consider a more compact and lightweight one. However, size and weight may be less crucial if you plan to bring your bottle around the local neighborhood daily.

Design and style

There are many different styles and types of water bottles with filters. Each filtered water bottle has a unique design that helps it perform its intended function. A water bottle could have a bigger capacity and a carrying loop for daily usage. Those intended for harsh situations may be made of polypropylene, a tough material that will not dent if dropped. Color and ornamental design are also important considerations.

Price

The cost of receiving clean water through these filters varies substantially, even though they all serve the same primary purpose. Furthermore, when your health is at stake, buying a cheap bottle from an unproven brand is not worth it. A filtered water bottle should be relatively inexpensive, though. We wanted to make sure you could receive quality without worrying about money.

Type of material

Like conventional reusable water bottles, filtered water bottles are made of various materials, the most popular being plastic and metal. It is entirely up to individual choice and intended usage when deciding which material to use; however, if you choose plastic, be sure it is free of harmful chemicals like BPA. Some water filter bottles are composed of lighter, more malleable polymers that can be folded up. Metal water bottles may be heavier and more clunky than plastic bottles, but they tend to be insulated and will keep your water cooler. For some purposes, certain materials will work better than others. The technology it uses, how dependable it is, and how thoroughly experts have tested it are what matter most.

Who It's For

The heavy-duty filtered water bottle Grayl's GeoPress Water Purifier Bottle is the ideal travel companion for hikers, backpackers, and campers. It is designed to keep you hydrated on the toughest routes, throughout international travel, and during any strenuous physical activity when access to drinking water might not be possible. Because of its strong build, it can withstand the worst circumstances. Simply fill the bottle, squeeze it down, and guzzle away.

Why It's Great

The GeoPress filters use electroabsorption and many layers of ultra-powdered activated carbon. This produces fresh, drinkable water from any water source without cross-contamination. Given that it can remove bacteria, protozoan cysts, heavy metals, and waterborne viruses, the Grayl system essentially doubles as a water-purifying bottle thanks to this level of filtration. Although filtering and purifying accomplish the same thing, a purifier offers an additional layer of security by getting rid of germs and viruses.

The GeoPress has fulfilled or surpassed NSF/ANSI procedures 42 and 53 for pathogen and chemical removal after undergoing independent testing by a licensed lab. This equipment has also satisfied the EPA's criteria for the testing procedure for microbiological water purifiers. It eliminates various pathogens, such as Rotavirus, Hepatitis A, Norovirus, Giardiasis, Cryptosporidium, E. Coli, Cholera, Salmonella, and Dysentery. Additionally, thanks to GRAYL's award-winning One-Press worldwide protection certification, this bottle can defend you from dangers on all continents worldwide.

While also incredibly adaptable, the GeoPress enables travelers to filter 24 oz of water in only 8 seconds. It is perfect for sharing water with others by letting them fill their containers with purified water and cooking in the wilderness. The bottle is constructed of sturdy BPA-free polycarbonate. The water filter feels strong due to its large base diameter. It can withstand the rigors of travel since it can withstand a 10-foot fall onto concrete when filled with water.

Potential Flaws

Pressure must be exerted on the bottle's bottom to force water up through the filtering mechanism. Unfortunately, some people have had difficulty since they lack the power to push it. Since the manufacturer advises placing it on the ground when using the Geopress, several people have found that the outer shell fractures when driven under pressure.

The rubber grips make it difficult to put it into a mesh side pocket or other tight spots in your bag. Additionally, GeoPress' filter could only last for a short time with significantly contaminated water since this particular filter is exhausted more quickly than others (350 purification cycles, or 65 gallons), which is the maximum recommended for each filter cartridge. Lastly, it's also relatively pricey compared to other choices. However, GeoPress is worth the additional money if you want the highest quality product experience.

Other Features

Using the Grayl GeoPress to purify water is straightforward. All you need to do is fill the bottle's outer portion with contaminated water, reattach the inner, and apply pressure with the rubber pads. Water is pushed through the filter and collected in the bottle's clean interior. Additionally, this Grayl bottle is relatively simple to clean up, which is crucial if you use natural water. The GeoPress water filter bottle's mouth is large enough to accommodate ice cubes and your whole hand, so a sponge can truly reach the bottom of the container. Be sure to completely dry the filter bottle before storing it to prevent the inner and outer pieces from sticking. The SoftPress pads and TPE TopoGrip material help keep the bottle from sliding from your hands while you climb over rocks or through crowded airports. Additionally, the GeoPress is offered in five colorways, including Bali Blue, Camo Black, Oasis Green, Wanderer Red, and Coyote Amber.

Who It's For

According to the Brita website, these bottles aren't meant for outdoor use—they're only meant for filtering tap water—but this bottle also cleaned natural freshwater well. So, this is a top-rated water bottle for those who like to hydrate with filtered water at work, at home, or wherever else you have access to tap water. Its simple design, contained straw, and easy-to-hold handle makes it perfect for daily usage.

Furthermore, Brita's bottle is insulated, easy to clean, and can be used with one hand—ideal for driving or computer work. Lift the top, sip through the straw, and enjoy refreshing water at the gym, a conference, or a concert. For those on the go who are concerned about the flavor and cleanliness of their drinking water, this is our suggested solution.

Why It's Great

This water bottle is WQA certified and filters water as you drink. Each Brita filter contains a unique combination of activated carbon and a binder encased in a BPA-free polymer. This block of activated carbon reduces chlorine taste, odor, and particles. It's interesting to note that the filtering process keeps the beneficial minerals and electrolytes present in tap water. In particular, the filters keep a healthy amount of fluoride, which is good for strong teeth.

For secure and pleasant hydration throughout the day, Brita's stainless steel filtered water bottle has a leak-proof top and double-wall insulation to keep 32 oz of water cool for more than 24 hours. It is made of stainless steel, making it solid and stylish, with seven additional colors (Carbon, Rose, Jade, Marina, Ruby, Blue Jay, and Glacier). Its exterior body is composed of BPA-free plastic, making it lightweight. Additionally, the replaceable detachable filter may clean 40 gallons of water. As a result, you no longer have to replace the whole bottle, saving you 1,800 plastic bottles a year. Filter replacements are also available at many different stores.

This button-operated flip-top bottle offers filtered water and convenient one-handed sipping and is simple to use at the gym or while working. Another outstanding aspect of the Brita is that, unlike other button-operated caps, it is sensitive and always reacts with a single touch. The spill-proof top on Brita's bottle lets you toss the bottle into the bottom of a messenger bag or gym bag on your daily commute without having to constantly dread it spilling onto and into your other belongings. It is simple to strap to a bag or backpack using the built-in carrying loop for a handy, portable water bottle.

Potential Flaws

Without straw cleaners, it might not be easy to clean the straw by hand. If it is not properly and frequently cleansed, mold can readily form. As the black spots grow over time, getting rid of them becomes more challenging. If not thoroughly cleaned, these black stains might ruin your drinking experience in the long term.

Other Features

The filter is simple to install and replace; all that is needed is a quick twist to secure the filter to the underside of the lid. The straw will then function efficiently, with no extra sucking. The top fastens to the bottle with two complete twists, similar to the filter. Additionally, by using this drinking bottle, you are helping to preserve the environment. It undoubtedly reduces your everyday reliance on single-use plastic bottles. Free recycling service TerraCycle also contributes to lowering trash. All Brita goods, including the packaging used for the filter units, may be recycled through this service.

To surpass EPA regulations, its hollow microfilter has been tested for protection against bacteria, protozoa, and dangerous organisms. Due to its small size and speedy hydration in under a minute, this bottle is ideal for outdoor activities like backpacking and hiking.

Who It's For

For long-distance trekking and backpacking, the BeFree from Katadyn is among the most prevalent water bottle filters. This is partly due to its simplicity, portability, and lightweight construction. It was designed to swiftly hydrate consumers with minimal space needs! Given that it is so tiny and delivers rapid hydration in under a minute, having a Katadyn collapsible filtered water bottle for outdoor use is incredibly beneficial. This makes it the top-budget option water bottle filter for ultralight hikers and backpackers.

Why It's Great

Katadyn, a prize-winner in the outdoor business for about 90 years, is an expert at making non-potable water safe for human use. You may easily use the BeFree water bottle filtration system by filling the hydration-bladder-like sleeve with water from any source, capping it off, and then squeezing it to take a sip. Despite its tiny size, the 0.1-micron hollow fiber microfilter in the fibrous EZ-Clean membrane removes bacteria and protozoa from 1,000 liters of water, surpassing EPA regulations, before it has to be replaced.

And, with a flow rate of 2 liters per minute reached by pushing a collapsible flask full of unclean water through the filter mouth, the BeFree is one of the quickest on-the-go portable water filters available. This pick keeps water in a soft flask pack instead of a conventional water bottle, which can be readily shaped to fit into any backpack, bag, or purse. Thus, the Katadyn BeFree bottle is an easy choice for our best lightweight option since it can be compressed to fit into even the tiniest and tightest locations.

The BeFree is quite simple to set up. It is prepared right out of the box. Water may be added by scooping it up and then screwing the top. While this is straightforward, since you need to scoop water into the container, you may need help obtaining water from extremely skimpy and shallow sources. However, it works in the majority of situations.

Potential Flaws

Hydrapak manufactures the soft bottle, which is relatively durable overall and devoid of glaring design flaws. The seams all are well-made and strategically placed. Also, the bottle is composed of strong, highly pliable BPA-free plastic that can handle light abrasion. However, the bottle's propensity for leaking and shattering has drawn criticism from many consumers. We advise against placing it next to angular rocks or branches that appear to be sharp. In the right conditions, the soft water bottle will puncture, which might be a serious issue if you're in the woods and dependent on this item to keep you hydrated. While it could be more sturdy, it is compatible with various soft bottles, which adds to its versatility. Therefore, we recommend purchasing a second soft bottle as a backup if you don't have another filtration system. Despite that little drawback, trail runners and hiking mavericks claim that BeFree is still their preferred filtered bottle for budget-friendly, lightweight, on-the-go requirements with easy handling and storage.

Other Features

To make things any more straightforward, the BeFree consists only of the filter with the mouthpiece and the soft bottle. There are only two parts and no additional or loose parts for upkeep. To clean, you may either remove the filter and swish it about in a stream or shake the filled water bottle to clear any particles from the filter before emptying it. Both methods are easy to do. Furthermore, hikers and backpackers may fill up their water reservoirs by squeezing the water through the filter.

Almost Made The Cut - Sawyer Select S3 Water Purifier Replacement Bottle

Almost Made The Cut

Sawyer Select S3 Water Purifier Replacement Bottle

Sawyer Select S3 Water Purifier Replacement Bottle

Sawyer features a 0.1-micron purifier cap and an internal foam filter that expels viruses and heavy metals.

There are several different clean-water tools from Sawyer Products, but this purifying water bottle employs a double-filtration method called Foam Adsorption Technology. While the external micron water filter eliminates bacteria, protozoa, cysts, dirt, and sediment, it also filters out heavy metals, chemicals, pesticides, and viruses. Foam fills the interior of the Sawyer Select bottle, which is composed of silicone that is BPA-free and food-grade. Also, BPA-free plastic is used for the various caps and the external micron water filter.

Who It's For

With its extensive list of hardness particles, the Sawyer Select S3 Water Purifier is an excellent choice for individuals who are always on the road. It is a fantastic alternative for water bottle filters because of its lightweight design and simple folding technique, but it also offers excellent performance. So, whether you're planning a tough backpacking trip across the country's stunning landscape or ensuring clean drinking water on a 2-week vagabond trip, the Sawyer S3 will always get your back and make you glad you have it. If you don't travel often, you can still utilize this at home or the gym and get the same advantages.

Why It's Great

The Select S3 is a double-stage purifier that can handle the most challenging water sources. It employs foam absorption technology, a water purifying system that is most effective in emergency conditions for removing impurities, including germs, pesticides, viruses, and heavy metals like lead. The top-mounted Micro Squeeze Filter eliminates all additional silt, particulate matter, and microplastics in addition to the usual pathogens. Satisfying the EPA filtration criteria, the silicone bottle filters the water in 10 seconds by alternately squeezing the bottle. Then the filter may be used to distribute the clean water into a container.

Furthermore, with this option, you can enjoy safe, clean water wherever in the world, as it removes practically all toxins in freshwater while enhancing flavor and odor. Most water sources, including spigots, sinks, faucets, and even streams, have a metallic taste due to the age of the pipes through which the water flows. The S3 drastically reduces that flavor and replaces it with one more akin to bottled water from the store. It's not precisely Smart Water, but it's also better than trying to drink from a fraternity bathroom's faucet.

The S3 can be appropriately kept with or without water since the patented foam filter and materials used in the bottle's manufacture inhibit the growth of germs and other odor-causing pests. The bottle's interior will remain unscented even if you use it intermittently for business travels over a few months. Additionally, Sawyer provides a lifetime warranty against production flaws.

Potential Flaws

The S3 is relatively lengthy in design yet slightly compressible owing to the foam insert not taking up the full capacity of the bottle. Over-compressing the foam filter, however, can shorten the foam's overall life and permanently ruin it. Since it is one of the few filter systems that genuinely deals with viruses, even higher-end hand-pump water filters won't accomplish that; damaging the foam essentially loses its value. Additionally, several customers reported having trouble getting water to pass through the filter consistently without using both hands. The additional suction required is primarily due to the 0.1-micron filter squeezing a lot of water through many microscopic pores, resulting in purer water. Still, all that purity comes at the expense of that more effort.

Care and Maintenance

Is it machine washable?

Most bottles—NOT the filters or purifiers—should be safe to use in the dishwasher, but you should follow the manufacturer’s instructions precisely. To avoid damage, some manufacturers advise, for instance, that you place the water bottle on the high rack of a dishwasher. Therefore, look for suggested maintenance guidelines on the manufacturer’s website before buying a new filtered water bottle. If a filtered water bottle is dishwasher safe, it will often say so in the product description.

Water bottle labels that are dishwasher-safe come in a variety of forms. Your water bottle may feature the wording “dishwasher safe” or one of the following symbols on the bottom:
– a square with an emblem of a cup and fork within
– a square with a wine glass and water drops within
– a plate or some plates with water drops or dotted lines above

If your water bottle can be machine washed, please take the filter off before putting it in the dishwasher. Except for UV light purifiers, most filters and purifiers can endure brief rinses in fresh, room-temperature water. Any extreme heat, cold, or force can harm the filter’s sensitive constituents and render it useless.

How to wash and dry

Cleaning most filtered water bottles is as easy as cleaning most normal ones. But, since the materials used in the bottle and the filtering/purifying elements vary significantly from one model to another, always consult the manufacturer’s recommendations for your specific bottle. Simple soap and water should work if you want to wash your water bottle daily.

Usually, all you need to do is remove the filter, put the bottle in a gentle dishwashing solution, and use a sponge and a bottle brush to clean every nook and cranny. Due to its difficulty to wash, the bottom of the bottle occasionally becomes a breeding ground for germs and mold. By cleaning it often, odor-producing germs won’t spread too rapidly. Then, allow them to air dry at room temperature.

Try to clean the filter as well, but you can’t clean it from the inside. With a clean, moist cloth, wipe the filter casing’s outside. Ensure you don’t wash the filter with any soap or other chemical treatments except as approved by the manufacturer. Never place a filtering or purifying assembly in a dishwasher or freezer or submerge it in extremely hot or cold liquids (including clear water).

Where and how to store when not in use

With so many choices for excellent filtered water bottles, it’s simple to amass a sizable collection. Keeping the kitchen organized is a typical challenge. The mess may be overwhelming, from broken caps to overflowing reusable filtered water bottles. The first thing to remember is to store the bottles only once they are totally dry. In many cases, leftover water causes bacterial growth and general muck. To be extra sure, keep the bottles upside down so that any water that could have gotten left behind might drop out.

A wine rack may be used to display your collection. For this method, the bottles must be resting on their sides, so properly dry them off beforehand. Another helpful item is movable bins that you can access from your pantry. They won’t tumble over, and you can quickly view all of your options because they double as a drawer. Keep the caps of your bottles in a smaller container within the larger one if you want to store them upside down. If your bottle’s lid cannot be removed, keep it open when storing.

Last but not least, place drawer dividers in a drawer tall enough to support your bottles while making sure the lids are left open to allow for adequate drying. If you intend to keep the filter for a while, give it a quick cleaning under running water and let it air dry. Then, you can put it in a ziplock bag and keep it in the kitchen cupboard.

In case of odor

Filtered water bottles are much better than single-use plastic water bottles since they are ecologically friendly. However, the major drawback is that people aren’t cleaning them correctly, which causes them to grow an odor that discourages people from using them. Or even from buying new ones, which may get expensive over time and produce more trash. Glass and plastic frequently hold onto smells. Fortunately, food-grade 18/8 stainless steel is typically a better option. Nevertheless, reusable bottles without self-cleaning technology might get so dirty that they can make you ill.

There are several methods to eliminate the odor from your water bottle:

Soak in hot water

After leaving the bottle unwashed for more than a day, a thorough overnight soak in hot water should eliminate any slight stink. The following day, wash with warm, soapy water and do a sniff test to determine whether the odor has subsided. Try the next step if the smell persists.

Soak in a solution of baking soda

Due to its deodorizing properties, baking soda is frequently used in various cleaning procedures. Pour warm water into your bottle and then add 2 heaping tablespoons of baking soda. Let it sit for a few hours or, even better, overnight for optimal effects. After a thorough rinse, do another sniff test on your bottle. Still smells strange? Try the following technique.

Soak in white vinegar

Surprisingly, vinegar’s astringent qualities enable it to effectively neutralize smells. If you don’t have enough white vinegar, you can dilute it with warm water and leave it in your water bottle overnight. Rinse with warm, soapy water in the morning. There may occasionally be a vinegar smell after the soak, but don’t worry—an additional overnight soak in hot water should eliminate the scent.
