Changing the filter of your air conditioner is crucial for its optimal performance. A clogged filter can lead to inconsistent temperatures in the space the unit operates in, weakening the power of the air leaving the system.

Regular cleaning and changing of the filter can reduce the risk of having air full of impurities being circulated around you and those you live with. The mold and mildew growing on your filters could move to other areas and 'infect' the rest of the unit, putting your health at risk.

Remember, it's always better to err on the side of caution and clean your filter more frequently if you're unsure. This will help maintain your air conditioner's performance and indoor air quality.

Fiberglass air filters are the more affordable option, but they need to be changed every 30 days or less.

Pleated air filters are more expensive upfront, but they're also more efficient at trapping particles and can last up to 90 days.

The type of filter you choose will greatly impact how often you need to change it. If you go with a fiberglass filter, be prepared to change it frequently.

The frequency of use is another key factor. If your air conditioner runs frequently or for an extended period, you should clean the filters more often. In fact, cleaning them every two weeks is the best option to improve the efficiency of your air conditioner.
