have made a difference in the amount of dust in the air

Not the best filters on the market, but better than standard and very affortably priced.

Worked great reasonable price will definitely buy again

Great product and price. Delivered promptly

Great quality & much cheaper than I can buy in the store with more quantity- win - win in my book!

Good price and usually in stock

Good quality for a good price

Great to have on hand without going to the local supply store.

Purchased several times. I like that they are on instant savings from time to time. Good quality filters.

Four pack of 12 x 12 air filters cost $20 ea at Home Improvement stores. So four pack for $39.99 is a deal.
