It’s important to change an air conditioner filter at least once every few months to guarantee your air conditioner works at its optimal level of performance. The filter acts as a barrier between unwanted debris and the air conditioner system . Over time dirt and debris can cause an air conditioner to run poorly and can reduce the life of the unit. A properly changed filter can also prevent allergens from getting into the house and keep the air inside the house cleaner.
Read the owner’s manual to find out where the filter is located.
Remove any screws holding the compartment in place, and store them in a safe place so you have them after you replace the filter.
Filters come in many different varieties from the more inexpensive unit that you will need to change an air conditioner filter more often to a higher-grade filter that will trap many smaller particles and can prevent allergens from entering the air system in your home.
Follow the directions on the package. The sides are usually marked as air-in and air-out.
- Another type of filter is an electrostatic filter. This filter will cost more, but it does a good job of filtering dust and particles. It also is reusable. It only needs to be cleaned with water, dried and replaced.
- Not all filters need to be replaced. Some air conditioning units have filters that must be cleaned and reused. These can be cleaned with an air compressor or water and replaced.
- Some of the best replaceable filters can filter out almost all fine particles and allergens. These fine filters need to be replaced more often than their counterparts because they collect so much more.
