12x20x1 MERV 11 Pleated Air Filter

They are the best.

So far we are pleased with our purchase. Great price and fit. Super fast delivery. Time will tell on how effective they are, but they seem to be working well keeping the dust down.

Plenty of filter options, fast shipping, excellent customer service (I ordered the wrong size filter in my original order and it was dealt with professionally and expediently!) and, most of all, a terrific filter! I will definitely be ordering again!

We have four returns (three different sizes) on our HVAC system. Each needs a filter. I checked a lot of websites and local stores for the MERV 11s that I wanted before purchasing a reorder plan with FilterBuy. Most economical plan for us with change every three months and our limited condo storage space was to buy four of each with annual automatic reorder and to order the other four (for the second same size return) at the six month mark each year.

Shipment arrived quickly and the filters are great quality. Will order from here again!
