There’s a lot that goes on behind the scenes of your AC, and here to help you is Hometown Heating & Air of Milwaukee in Cedarburg, WI. The filter of the AC unit is responsible for catching debris and making sure that the appliance runs at maximum efficiency. When a filter becomes full of dirt, dust, and other debris, you need to empty it right away. However, it’s crucial that you don’t reuse the filter. While it might seem perfectly functional, there are a couple of reasons why this is not advised. Here’s a breakdown of some of the dangers of reusing AC filters.

Poor Air Quality

Reusing AC filters simply leads to poor indoor air quality. The whole point of a filter is to remove dust and other particles from the air, but when you reuse a filter, it loses effectiveness each time. Some of the smallest particles will be passed on from usage to usage, and the filter can become too clogged to do its job in a productive way.

If you’re committed to the best air quality in your home, you’ll want to use a new air filter each time. In particular, people with preexisting health conditions should focus on air filter quality. Don’t rely on a separate air purifier to clean things up. The effect of a reused air filter should not be underestimated. Breathing in air that’s of such poor quality is a health risk that most people if they are aware of it, would simply choose to pass on. It’s just not worth the price of an AC air filter.

Mold and Mildew

AC filters that have been reused can also accumulate mold and mildew. These substances are not healthy to inhale either. If you have asthma or allergies, you want to avoid mildew at all costs. These particles can infect your lungs and make it more difficult to breathe. In the worst-case scenario, you could be looking at hospitalization for an extended period of time. You shouldn’t settle for reusing filters that are ridden with mold. Take some time to purchase a new supply of air filters for the next year.

Non-reusable Filters

There are two types of AC filters on the market. Reusable filters are specifically designed to be used over and over again. Non-reusable filters don’t have this sort of durability and must be disposed of when full. If your unit’s filter is non-reusable, you’re fundamentally at risk for respiratory issues when you reuse the filter.

It simply isn’t designed for this purpose. If you’ve never inspected your unit’s filter, take a moment to do so, and see whether it is reusable. From there, you can simply follow the manufacturer’s recommendations on how to proceed.

Rough Handling

When you reuse a filter, you’re exposing it to some rough handling. You might try to be gentle with the device, but some damage will occur no matter what. The edges of the filter might show signs of wear and tear as they are repeatedly folded over. If you use water to clean the filter, water droplets can slowly cause deterioration as well. Once the filter is clean, it will be inserted back into the unit in a worse condition than when you removed it. While this might not be super harmful at first glance, keep in mind that damage can add up over time. On your third or fourth time of reusing a filter, it will be in a much worse state than before.

Undetectable Dangers

Finally, the dangers of a reused filter are often hard to detect. If mold or mildew has accumulated, you might not be able to smell it with an untrained nose. If the filter has ruptured from the inside, this won’t be detectable until you actually open up the unit. From the outside, it could very well look like everything is running just fine.

Because these dangers aren’t always visible, you have to keep in mind that they could be severe behind the scenes. By using new AC filters, you reduce the chance of any of this happening. You don’t have to worry about the condition of your filter on a daily basis. Tossing out your filters is good for your peace of mind. And generally, the cost isn’t too inhibitive.
