Experts recommend replacing various household items like pillows, kitchen sponges, bath mats, plastic food storage containers, toothbrush holders, mattress protectors, shower liners, shopping totes, reusable water bottles, and cutting boards more often than most people realize. The timelines for replacement vary, with some items needing to be swapped out every 6 months to 2 years to maintain cleanliness and functionality.

Why it matters

Holding onto household items past their prime can lead to the buildup of dust, dirt, bacteria, mold, and other issues that can impact health, hygiene, and the lifespan of the products. Regularly replacing key items helps ensure a cleaner, safer, and more functional home environment.

The details

Experts recommend replacing pillows every 1-2 years as they accumulate dust mites, skin cells, and body oils over time. Kitchen sponges should be replaced weekly or bi-weekly as they can contain more bacteria than a toilet seat. Bath mats should be replaced every 1-2 years or washed frequently to reduce mold and bacteria exposure. Plastic food storage containers should be replaced when scratched or stained, with a focus on switching to durable glass containers. Toothbrush holders need cleaning weekly and replacement every 6 months. Mattress protectors and toppers should be replaced every 1-3 years as support and waterproofing degrades. Shower liners need replacing every 6-12 months to prevent mold and soap scum buildup. Reusable shopping totes and water bottles should be replaced when they become worn, cracked, or difficult to clean. And cutting boards require replacement every 1-5 years depending on material and use.

  • Pillows should be replaced every 1-2 years.
  • Kitchen sponges should be replaced weekly or bi-weekly.
  • Bath mats should be replaced every 1-2 years.
  • Toothbrush holders should be replaced every 6 months.

What they’re saying

“Most pillows should be replaced every 1–2 years. Over time, they accumulate dust mites, skin cells, body oils and lose structural support, which can affect neck alignment and sleep quality.”

— Dr. Regina Lark, Founder of A Clear Path (Good Housekeeping)

“Kitchen sponges can contain more bacteria than a toilet seat.”

— Dr. Regina Lark, Founder of A Clear Path (Good Housekeeping)

“Bath mats sit in a damp environment and collect skin cells, so replacing them every one to two years (and washing frequently) reduces mold and bacteria exposure.”

— Sofia Martinez, Cleaning expert, professional organizer, and CEO of Sparkly Maid Austin (Good Housekeeping)

“Plastic food storage that gets scratched or stained can trap bacteria. When replacing, consider moving to glass containers which will last significantly longer and be safer.”

— Amanda Wiss, Founder of Urban Clarity (Good Housekeeping)

“Reusable water bottles also harbor significant bacteria because they're handled constantly but rarely sanitized.”

— Dr. Regina Lark, Founder of A Clear Path (Good Housekeeping)

The takeaway

Regularly replacing common household items like pillows, sponges, bath mats, and water bottles is essential for maintaining a clean, healthy, and functional home environment. While it may require more frequent shopping trips, the benefits of swapping out worn, dirty, or bacteria-harboring items far outweigh the inconvenience.
