What is The Advantage of HEPA Air Filter Over Traditional Filter?

Is there an advantage of a HEPA air filter over a traditional filter?

If you’re on top of your air filters and changing them as frequently as you should be, you’ve probably come across the HEPA air filters. HEPA air filters, or high-efficiency particulate air filters, work by forcing air through a fine mesh trapping particles like pollen, pet dander, dust mites and smoke.

With how often you should be changing your air filter (a few times a year) you may be tempted to go with the cheap fiberglass filters for a couple of bucks. After all, is there really an advantage to purchasing a higher-quality air filter, like a HEPA air filter, that costs more? We’re here to let you in on the HEPA advantages you may have been missing out on.

We have gone over the importance of indoor air quality previously here. Indoor air quality affects your health, especially if you or someone else in the home has asthma. Being exposed to and breathing in things like pollen, mold spores, dust mite debris, smoke, pet dander or smog can leave you with headaches, sore throats, and skin rashes. Your air filter is what protects you from breathing these things in your home.

As we mentioned earlier, the fiberglass air filters are definitely the cheapest, but they are don’t do very well when it comes to removing particles from the air; we’re talking less than 10% of the pollutants are removed.

Another more traditional option would be the pleated air filter. These remove up to 45% of particles in the air and usually cost around $10. While a better option than the fiberglass filter, it is still inferior to the HEPA air filter.

High efficiency air filters remove up to 85% of the air pollutants in your home, which is a number that can leave you sleeping easy at night. (You’ll probably be sleeping easy with all that clean air to breathe!) And a true HEPA air filter used for a whole house filtration system or air purifier can remove up to 98% of the pollutants in the home.

Fiberglass air filters are actually pretty good when it comes to trapping large particles in the air, but don’t handle the small particles very well. While HEPA air filters aren’t as good at catching large particles, they are much better at capturing the smaller particles. But the smaller particles are much more harmful to your health; these are the ones you want to worry about trapping.

The effectiveness of the HEPA air filter and the importance of air quality to your health are two simple yet powerful reasons why these high efficiency filters are superior to any other option. By investing in a HEPA air filter you can ensure you and your family will be breathing cleaner air.
