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

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.

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.

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

It is a good filter, but I’ve been told now by three different air-conditioning companies that they are too hard on your air condition unit and it makes them work too hard and to go to a lower grade.

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.

[This review was collected as part of a promotion.] We were admittedly overdue to change our filter and noticed an almost IMMEDIATE difference in the air. I had been waking up with headaches recently, which have since stopped, and I attribute to allergens that had been coming through the vents from our old filters. We are extremely happy with these filters so far!

[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!

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.] This filter is easy to install. The construction is solid and not flimsy. You just slide it right in. Fits perfectly with my HVAC system. My whole family have allergies year round living in the south, so we need something that works, efficient, and easy to install. This meets all my criteria. This filter is supposed to capture 2x the bacteria and virus, so with all that going around, this is important to me. I feel my whole house breathes a bit better. I also like the fact it also catches cough debris and lint! Lint is something we definitely have a lot of in our house. So good so far. I will continue to use this product.
