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

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 .

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

Online ordering and delivery of the air filters in bulk is convenient for having them on hand when it’s time to change them often.

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.

This is such a great deal buying them in a 4-pack like this. They work better than the cheaper ones I was buying before.

These seem to work very well, there is much dust around the house since we’ve been using these filters

So much better than those flimsy ones. May as well spend a little more and not have to replace so often.

Very difficult to put in place… very tight fit. Since the filter goes into the ceiling, it is really a struggle to get the filter to fit properly.

good rated filter, enough description to make a decision on which level I needed, but all in all, it is a filter. not much else to say!!!
