Clean Your Vents Day is celebrated on June 15 and we’re here to tell you all about this helpful holiday. You’re probably wondering what this day is all about, right? Well, the idea is that maybe we should take more time to just celebrate the little things in life that we never think about. Like the external vents and exhausts on our house. We’d all be a lot more uncomfortable without them – think of all the humidity and lack of cool air in the summer?

The idea behind this holiday is to act as a useful reminder to homeowners to care for every aspect of their house. Taking time out at least once a year to clean out those useful vents is one way to do just that.

History of Clean Your Vents Day

Ventilation is one of the oldest features of human structures. Since humans first started constructing homes, the need for ventilation has been a key concern, especially once we started using fire. Fire is one of the milestone discoveries for humans and it became, and still is, a necessary survival tool. Early humans used fire to keep warm, cook food, and as a source of light. Just picture a tent or hut with an ever-burning fire in the middle. To keep the fire going, and give the smoke somewhere to go, a hole at the top is made. This is an example of basic but effective ventilation.
From those early huts and tents, humans began to build more complex and sturdy homes. Brick, stone, and wood became the staple building materials. But ventilation was still a key feature needed to keep homes cool and the air clear by allowing fresh air in and smoke out.

Soon houses all featured chimneys linked to fireplaces and stoves, but the evolution didn’t stop there. Today, eating and ventilation systems are separate, and are no longer one system like back in the day. Our multiroom homes are all provided with fresh air thanks to our air vents. So take time to say thank you for the centuries of invention that led to the comfortable life we know today.
