Great filters!

I always buy these filters due to the fact Ace puts them on sale & they work so good! We live in the country & there's lots of field dust so I replace them every 1-2 months & have never had a problem with them. I will keep buying them!

Furnace filter

Your ad is deceptive! Led me to believe I was getting 4 filters and only received one. For what I paid, I could have shopped locally for the same cost. I believe you owe me 3 more filters.

Not as described

I received a notebook when I ordered these filters. This is a 3rd party company not directly from Walmart and the packing list for filters was included in a box with one notebook and ZERO filters. The box was smaller than a 16x20 as well. Terrible.

Reliable in every season

I've tried other furnace filters that are OK. While I don't have scientific proof of their effectiveness, I've lately gone for this kind because of their reliability and a general sense that I'm having better results for reducing allergens in the air. I react to dust, and until recently we also had a cat who shed lots of hair! Early in the pandemic I also gained loyalty for 3M when they insisted that their PPE products made in the USA continue to be shipped to Canada.
