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!

[This review was collected as part of a promotion.] I received the 3M Filter Ultra Allergen Bacteria and Virus 1600 MPR 1601 4 ok 16 in. × 25in × 1in (49.6 cm × 63.5 cm × 2.5 cm ) filter for my furnace and they are wonderful I love that they are Ultra Alergan that so important because my family has allergies for so many things and these are helping so much.

[This review was collected as part of a promotion.] We love this air filter. It’s made heavy duty. The most important thing is it’s designed for allergens. And that’s important to us because I have to take allergy medicine every day and this is just an extra step in blocking out the allergens. We have four dogs and so there is a lot of pet dander in our home. These air filters are absolutely the best, they are a little more expensive than the cheap ones but they work so much better. Take it from someone that is highly allergic to a lot of things, these work great.
