Can I Reuse a 20x25x1 Air Filter in My Furnace or HVAC System?

Indoor air quality has a major impact on the wellbeing of the people living in a home. Air conditioning filters can help improve the air quality if they are the right type and installed and used correctly. There are two types of filters you can use: disposable and reusable. Disposable HVAC filters must be changed every month or quarter, depending on several factors.

A washable HVAC air filter, as its name implies, can be washed and reused multiple times. In theory, an air filter that is simply rinsed and put back in the furnace can save you time and money. Replacing your furnace air filter regularly is one of the best ways to maintain your heating, ventilation, and air conditioning system. Air filters in your home are tools used to keep the flow of incoming air clean and comfortable for breathing.

Over time, air filters become so clogged with smaller particles that their efficiency decreases. If you're on a tight budget, you can opt for disposable filters because the cost per filter is lower than that of washable units. Using electrostatic filters means that you don't have to worry about this issue, as this type of filter has a lifespan as long as that of your furnace or air conditioner. Over time, as the air filters in an air conditioning system clean the passing airflow, the smaller particles they capture start to clog the mesh fabric.

If the filter is not changed, the furnace will not work efficiently, leading to potential problems with the HVAC system and affecting the air quality in your home. The main purpose of a filter is to prevent air contaminants from entering the furnace and the air in your home. The air is free of harmful microscopic particles, but like regular air conditioning filters, they will eventually need to be replaced. Filter King offers a subscription service that eliminates the need to wash them simply by replacing HVAC filters.

Air filters are classified according to the Minimum Efficiency Report Value (MERV) system, which determines the efficiency of a filter. Homes in areas with high levels of allergens, contaminants, dust mites, mold spores, and debris have a washable air filter that constantly captures airborne particles. The higher the MERV rating of the air filter, the smaller the particles it can capture, but the greater the effect it will have on airflow. You'll need to clean your air filters regularly to avoid any issues with the quality or flow of your home's air.

The filter is also washable and reusable so you can enjoy fresh, healthy air for an extended period of time.
