How to Change Your 20x25x1 Air Filter: A Step-by-Step Guide

When it comes to changing your 20x25x1 air filter, there are a few essential steps you need to take. To begin, you'll need to determine the size of filter that is required for replacement. It is important to turn off the oven before removing the current filter, which can be found either inside the oven or through the return air vent. The size number of the filter is located on the cardboard frame.

It is imperative to understand why it is necessary to replace your home air filter every 3 months, or 90 days. The oven heats the air and then a fan blows it out into the house, distributing it throughout. Air filters are usually made of spun fiberglass or pleated paper framed with cardboard for increased stability and rigidity. Allergens and pollutants are absorbed into the filter, improving indoor air quality as the air becomes cleaner. When it comes time to buy new air filters for your air conditioning system, there are a few factors to consider.

These filters act as barriers to prevent contaminants from entering the system or circulating through the air. Some air conditioning systems have filters inside the return air ducts located in various rooms in the house. The boiler filter prevents air passing through the fan from distributing dirty, unsafe air to the house. The only type of filters that trap allergens and spores are HEPA, or high-energy particulate air filters. The Minimum Efficiency Value (MERV) rating for an air filter measures how effectively it prevents dust and other contaminants from passing through and into the air stream. Once you have purchased a new filter, insert it into the designated opening of your home's boiler or air conditioning system with the arrow on the frame pointing toward the fan motor.

It is important to use an air filter with a MERV rating that is recommended by the boiler or air conditioner manufacturer in order to avoid impairing its performance.
