Washable air filters have a MERV rating of 1-4, meaning they only capture particles larger than 10 microns. Pollen, dust mites, and lint are all 10 or more microns in size, so a washable filter can prevent these types of debris from circulating in your HVAC system. They are a greener option than disposable filters and can save you money in the long run. Disposable filters are more effective at trapping smaller particles, such as pet dander, bacteria, viruses, and smoke.
Since using a wet filter can promote biological growth and indoor air quality issues, it's important to change them regularly. Whichever oven filter you choose to use, it's one of the most important maintenance tasks that can be performed on your system. We've compared the two options based on cost, environmental impact, performance, and maintenance requirements to help you choose the best HVAC filter. These filters keep your heating and cooling system free of dust and dirt, and also eliminate allergens and contaminants that can cause discomfort and affect your health.
A higher MERV rating means that the filter would trap more dust and contaminants, but it may not be ideal since it also means that it is thick and dense, which could prevent airflow. The general feeling here at Star Heating and Cooling is that there are more negatives to using washable oven filters than benefits. Disposable filters are very affordable and only need to be changed every 30 to 90 days. You can also make your own custom-made washable oven filter to avoid having to constantly go to the hardware store to look for the right disposable filter size for your oven.
When the filter has accumulated dust and dirt after a few months, it is removed and cleaned with a hose to remove all debris. HVAC electrostatic filters are washable and reusable, capable of capturing up to 95 percent of the largest particles circulating in your home. This helps keep your home's indoor air quality high while helping your HVAC system operate as efficiently as possible. With the help of a filter, you will improve the indoor air quality of your home, allowing you to breathe clean and fresh air.
