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

These are the very best filters that you can buy. Sure hope they keep them in stock and available next year.

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 .

They fitb perfectly & do an excellent job. I love that Sam's usually has a great deal on these too. Highly recommend

I prefer these filters due to flair ups with allergies. They offer filtration of allergens so I think these are better.

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!!!

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 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.

My daughter has allergies and these filters work great and really seem to help with the desert pollen

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.
