Air filters come in different styles and rating systems, so you may come across terms like MERV, carbon, HEPA, pleated, and more. While these filters do the same job of trapping particles and debris from the air, they work differently and have different ratings.
Finding the perfect air filter for you by longevity depends on which filter you choose and how often you replace it. Not replacing air filters can compromise the efficiency of your air-purifying and filtration system. However, replacing them too often could just be a waste of money.
Knowing when to replace your air filter is a great way to keep your house clean.
Air Filters By Type
Each filter you use has its own longevity, and they include the following:
HEPA Filters—These filters tend to last one to two years, depending on the make and model of your air purifier. Your system should come with a manufacturer manual that can give you all the information you need, including how often you should replace your air filter.
Carbon/Charcoal Filters—Carbon and charcoal filters are great for collecting larger pollutants like smoke and gas. These filters typically last around 3-4 months.
Pleated Fabric Filters—These typically don’t need to be replaced for six months to a year. The lower the MERV rating, the longer the filter will last, but the lower its filtration.
What Can Affect the Longevity of Your Air Filter?
The environment within and outside of your house can impact the longevity of your air purifier filter.
- Pollution: If you live in an area with high pollution, your filter will likely need to be replaced more frequently. This includes industrial areas, factories, farms, power plants, metropolitan areas, etc.
- Fires: Wildfires and climate issues seem to be spreading across the world. Smoke and fire are significant contaminants that can impact the longevity of your air filter, so if you have been experiencing fires, you may need to stock up on carbon filters.
- Pets: Few things can give us the peace and joy that pets can. They are almost perfect, but their hair and dander can trigger allergies and create indoor pollution for some owners. The more pets you have, the quicker your air filter will get clogged. Pet hair clogs carbon filters and HEPA filters, so check your filter regularly if you have a pet, check your filter regularly.
- Tobacco smoke: Smoking inside the house means owners should frequently replace their air filters. Smoking creates air pollutants that can impact the lifespan of the air filter.
When you keep your home clean, you can expect to have a longer-lasting air filter.
If none of these longevity factors apply to you, you should expect to see your air filter last precisely as intended. Air pollution is all around, and everyone’s health can benefit from a proper air purification system.
No matter where you live, air purifiers are necessary to improve air quality and protect your health. By following specific steps, you can ensure your air purifier is working as efficiently as possible for as long as possible. Remember to replace your air filter when necessary to ensure the best air quality in your home. Curious about when to replace your 20x20x1 filter? Click to learn more!
