The Dangers of Reusing AC Filters

August 16, 2020

Although there are specific types of air conditioner filters that are designed for reuse, most filters aren’t reusable. Unless your air filter specifies that it’s safe to clean and reuse, there are several reasons why you should discard it after use and install a clean one. Read on to learn why it’s important to never reuse old AC filters.

Mold and Mildew Could Grow

Air filters aren’t built to shed any excess moisture that gets on their surfaces. If you use water to rinse them off, the moisture that’s retained over days or weeks could encourage the growth of mold or mildew. In every area of your house where air circulates through your air ducts, these potentially harmful substances could be dispersed, putting you and your family at risk of health issues.

Handling a Filter Could Actually Cause Damage

Using any cleaning method to remove dust, dirt, or other substances from the surface of a single-use air filter could actually render it useless. If you tear even the tiniest hole in the filter or loosen its fiber density, the filter won’t perform properly. The end result of trying to save time and money by cleaning a dirty air filter could result in the need for costly air conditioner repairs over time. Replacing air filters at least once every two to three months is a much more cost-effective option.

Vacuuming Is Inadequate

The array of contaminants an air filter is made to capture get buried deep within the fibers of the filter. Even attempting to use a high-powered vacuum such as a Shop-Vac to remove these contaminants won’t be sufficient enough to reuse the filter. The leftover particles will accumulate within the filter and prevent fresh air from circulating, which could cause your unit to work with less efficiency.

If your reusable filter doesn’t seem to be working properly, it may be time for AC maintenance or repairs. Feel free to contact Dogtown Heating, Air & Plumbing today to schedule an appointment.
