> 3 dayI just installed this filter, so hoping it works, but... It advertises as 20x25x4. It isnt. It is actually 19.5 x 24.5 x 3 5/8. It does not fit tight in my system. Im hoping it seals well enough, and doesnt let the air flow around it. The photos are this filter next to the Honeywell original filter, which fits snugly and worked well.

Greater than one weekMaking USA products the right way! I have the hard to find size filters and theses guys had plenty in stock. Same quality as what I get from Lowes, Home depo, or Walmart; who have all stopped carrying the size filter I need. A big THANK YOU to BNX TruFilter! Keep up the quality and production, I have shared with family and friends.

06-06-2025This 4 pack was an excellent value. It is cheaper than buying a single higher quality filter from the grocery store for $14, especially after inflation. I wish I would have found out about these years ago, because it would have saved me so much money. Plus, these are super nice quality and super sturdy. I have pets, so I am super picky about my air filters and need more than the flimsy ones, and I also change mine out monthly due to the pets.
