How to Clean a 20x20x1 Air Filter for Optimal Performance

For optimal performance of your air conditioning system, regular maintenance of the 20 x 20 x 1 electrostatic or washable air filters is essential. To ensure the best results, it is important to rinse the filter with water and a mild detergent, using a soft brush to remove any sticky particles. Shake off any excess water and reinstall the air filter in the system. The air flow from the system will dry the filter completely.Different filters have different levels of efficiency that will determine the size and amount of dirt and debris that can prevent them from entering the system.

You can talk to your air filter supplier about the MERV ratings of the filters you use. Generally, reusable filters require cleaning around once a month, while thicker oven filters need replacement intervals of 9 months for 3 to 4 thick filters and 12 months for 5 thick oven filters.Oven filters are usually located below the oven, behind a slotted vent cover. Carefully remove the cover and set it aside. Next, be sure to look for directional arrows on the existing air filter.

These arrows indicate the direction in which the filter should be placed. If there are no arrows, it means that the direction of the replacement does not matter.Then, if you take those numbers and round them to the nearest inch, you'll have the correct nominal size of filter you need. In other words, the higher the MERV rating, the more the filter will restrict airflow, meaning the system will have to work harder. Clogged oven filters can let debris into the system, which can cause damage, increase energy bills, and even cause respiratory problems.It's very easy to forget to replace the oven's air filters, so it's a good idea to note it on your calendar or add an alarm to your phone as a reminder to check its condition.

The air filters can be changed from behind the intake grilles (often referred to as air filters or air conditioning filters) or in the boiler housing of the central air unit (often referred to as “heating filters”).If you can't find the correct nominal size, you may need to order a custom-sized air filter to ensure a proper fit. Studies have shown that maintaining a clean air filter in your air conditioning system can reduce electricity bills by up to 15%. When you decide to buy air filters, it's helpful to talk to a reliable, top-of-the-line supplier like Filter King.For your air conditioning system to work efficiently, it's important that you clean and maintain your 20 x 20 x 1 air filters regularly. If you don't follow all of these steps, your filter may get dirty again faster than expected.
