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 .

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

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

Right size/Wrong fit: These were the size I needed, however when I got home they would not fit in the vent, so I had to return.

I have not use but I have order before and use the brand but this time the price was higher and no rebate or discount,

I have used this type filter for years and they have done very well in keeping my furnace and air conditioning free of dust.

This is the only filter I’ve used since taking over the job of replacing the filter in my home, no problems with doing it at all.

Possibly the best whole-house air filter there is, the $10 discount is greatly appreciated in these difficult economic times!!!

Good deal for 4 of these filters. We live in SC and the pollen levels have been high so I only trust these especially during the pollen season.
