I have read filtrete is the best, I know that they're the most expensive but I have been using them for years, wish they cost less.

Great filters and bargain for 4 at Sam’s club price , turned on my neighbor to buy at Sam’s going forward

These are the filters we depend on. Their efficiency is obvious via the dog hair, lint, and dust accumulation after 2 or 3 months.

Great product last longer than other semilar filters and you can definitely breathe the difference. Price at Sam's is best deal we have found .

It's great to grab a bundle of these to have on hand, now I have no excuse for not changing the filter regularly

Since using these filters, my allergies have been much better. I like getting 4 at a time instead of one or two because I have several registers.

The filters are reasonably priced. You had to have them shipped to you but it was well worth it. Arrival date was as projected.

I got the filters without any issue. I've installed one and will know in a few months how well they work.

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

I have been buying these filters for many years, and they really do the job. Specially, if you have allergies, I would recommend them. Good buy
