Good product at a good price -- actually more convenient than the on-line filter service I used before.

Excellent filtration and price. I have confidence in the manufacturer and so happy that Sam's carries these products.

Yellow pollen and pet shedding time is driving my allergies bonkers but it likely would be worse if I was suing the usual filters.

Too costly and now can only get by shipping another rip off shipping scheme by sams club by taking them out of the store and making it online only.

Just started using this product. Too early to tell how it’s working. Not sure I will be able to tell if it works any better or worse than the last filters I used

I had to pull this and put in a temporary fiberglass filter after 1 week. The airflow to the farthest rooms was poor and the rooms got too cold. The pleating looked good and the filter isn't visibly dirty. I'll stick with the Merv 7 filters.

I'm unable to give a review at this time regarding quality or performance. I bought these because they were a good value and I expect they will perform great but until I use them I can't say with certainty.

I have three 20/20/1 and one 20/30/1. Use other brands no problem with the fit on the 20/30/1. I JUST SPENT HALF HOUR BENDING THE 30/20/1 to fit. Bought 4 packs year supply. Every three month I fight with the 20/30/1. The 20/20/1 fit with no issues. This is the last set for the year. Last year I should had Bought a different brand on the 20/30/1. Cause this will be the third year that I have purchased thrse. I will continue to buy the 20/20/1. I hope the company will fix the dize to fit Thank ypu

[This review was collected as part of a promotion.] I can't really say this filter works any differently from the Filtrete filters with a lower allergen protection. But I can say I haven't noticed any more dust in the air than with my old filter. It would be pretty hard to tell if there was actually less bacteria in the air. The filter is of good quality though just not sure the extra money for the Allergen Bacteria reducer rely does any more than the ones without that.

[This review was collected as part of a promotion.] I got this for our little rental house and it was exactly what we needed. The fit is perfect and the installation was a breeze. I use 3M a lot and knew the quality would be fantastic, so when it came to replacing the filter, there was no doubt I would get 3M. Highly recommend!
