Washable filters are a worthy investment for those looking to save money in the long run. Although they may be more expensive initially, you only need to buy them once every 5 to 10 years instead of once a month. However, this type of filter can only remove large particles from the air in your home, and cannot remove pet dander or smoke. If your family has allergies or asthma, a washable air filter isn't the right choice for your home.
Disposable filters are more effective at trapping smaller particles. Washable filters are only good at protecting against large particles such as dust. They don't filter pet dander, bacteria, viruses, or smoke, especially when they're not changed often enough. Washable air filters tend to have a lower MERV rating and are less efficient, while a high-quality disposable filter might filter the air better.
The air filter is designed to protect both the mechanical components of the boiler and the quality of your home's indoor air from particles suspended in the air. Replacing a wet filter in the HVAC system provides an ideal environment for mold and bacteria to grow. Because fiberglass filters cannot remove contaminants from the air, they are not recommended for people with respiratory problems. The general feeling in Star Heating and Cooling is that there are more negative aspects to using washable oven filters than there are benefits.
While the initial cost is higher, it's important to keep in mind that washable filters are expected to last nearly the same number of years as your unit. An air filter with a higher rating is designed to remove smaller types of pollutants from the air. Using electrostatic filters means that you don't have to worry about this problem, since this type of filter has a lifespan as long as that of your oven or air conditioner. For good air quality all year round, HVAC experts recommend pleated electrostatic filters for your oven.
If you're one of the many homeowners who use disposable filters, you might be wondering if it's beneficial to switch to a washable air filter. It's better than replacing them, you'll have full control of the chemicals being used and you'll have a permanent filter that works well for your needs. Even if you clean a washable filter every month, it will start to clog up with dirt over time.
