Leslie Cummins 28 days ago

So glad we have some where that we can purchase our filters at a discounted rate. Our filters for our home are very expensive and would not be able to change them as often as we avoid. But since we found discount filters we can do the most healthy and change more often. Thank you

Solid filter, not flimsy. No assembly necessary

Jeffrey Stultz 2 days ago

This was a very difficult product to find in the stores. I was able to order a two pack on-line for a much more reasonable price than trying to drive and find one all over town. Lowe’s has a filter that was the correct specs but did not fit my system, and it was more expensive. I am very happy with my purchase!

Its very simple, my AC guy wanted over $100.00 to come and install a new #11 (same as this one) filter and I got them under $25.00. The istall took 10 mins total. I will be back next time ( a year) for my next one! Doug
