How often should you clean air conditioner filter?

Clean or replace the air conditioning system filter or filters every one to two months during the cooling season. Filters may need more frequent care if the air conditioner is in constant use, if it is exposed to dusty conditions, or if you have pets with fur in the house. As a general rule, you should clean the air conditioner filters inside the indoor unit every two weeks. In dusty or more polluted environments, you should clean filters more regularly.

The only way to be sure how often the air filter needs to be changed is to perform a visual inspection of the filter every month. After a few months, you'll get an idea of how quickly it gets dirty. You'll need to re-evaluate if you're having a new pet or if the outside air quality has been poor. When you buy a new air filter, you'll find the manufacturer's recommendations for the replacement program.

Pleated air filters are more expensive at first, but they are also more efficient at trapping particles and can last up to 90 days, depending on use. The first thing to do to figure out how to clean an air conditioning filter is to turn off the air conditioner. If you have young children in the house, it's a good idea to use high-quality pleated air filters and replace them every two months. Children are more sensitive than adults to indoor air pollutants, such as mold, dust mites, dander and pollen, so make your home an oasis by using quality air filters and replacing them before they become too clogged and dirty.

After a period of smoke-filled days with poor outdoor air quality, inspect the air filter to see if it needs to be replaced. If you live alone, without pets and with good surrounding outdoor air quality, the manufacturer's recommendations for changing filters are likely to work well for you. To improve air quality, turn the thermostat fan switch from AUTO to ON. Replacing a clogged filter with a clean one can reduce air conditioner energy consumption by 5% to 15%.

It will be easier for you to remember to do this important task if you learn how often you should change your air filter in the first place.
