Just installed the new filter to our HVAC system. As of yet, the system has yet to run since it is early spring. Ask me for another review within the next 3 mos. One thing I can include on this review, a little bit disappointed because the filters are not individually sealed, like those of your competitors that are available from the stores. This means that I have to keep the shipping box closed at all times so that the filters do not get dirty/dusty.

I was looking for high efficiency filters that remove fine partials. It appears to be catching more than lower grade filters in the first two weeks!

These filters are great and have a good combination of High filtration and don't restrict the air flow. You do have to change them more often than the typical every 3 months that your typical spun fiberglass filters call for, but the significantly higher filtration of the air in your home is worth it. My wife and son have severe allergies and after installing these filters, weve noticed a lower amount of dust in the home. These filters are for people who want serious filtration of their home.

It’s so much easier, and safer, to purchase the filters from this company and get them in a matter of days (as opposed to shopping during this pandemic). Quality is what we expected; great value for the price paid.
