Been using Discount Filters for a couple of years now. I need the allergy Filters for my condo. They work every bit as well as the brand name Filters without the higher cost. Recommended.

Based on my home air quality sensors it appears that these filters do a good job in helping to cleani the air. When replaced after 6 months they show significant dust and dirt that were removed from the air. I think they are a good value for the money.
