[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.

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 got these filters because: -dogs -kids with mild allergies -changing filters regularly helps your heating/cooling system work more efficiently - I trust 3M Filtrete products -cold season is upon us and these filters have amazing bacterial and viral filtering capabilities. easy to install these are sturdy and fit my furnace perfectly. i noticed. reduction in air flow noise immediately as well as less dust on the furniture. Because my kids have inhalation allergies it is critical that we keep our home air as clean and filtered as possible and these do the job efficiently and effectively.

[This review was collected as part of a promotion.] The Filtrete™ Ultra Allergen 2X Bacteria and Virus Filter (1600 MPR), 16 in x 25 in x 1 in are great! These high-performance filters helped to improve my home’s air quality. They are durable and definitely help with allergens!

[This review was collected as part of a promotion.] This Filtrete™ MPR 1600 Ultra Allergen Bacteria and Virus Air Filters is doing a great job improving the air quality in my home. First of all, I love that it is a 90 day filter. That means I’m not changing it near as much as a fiberglass filter. I only need a few of these filters to keep me stocked for the entire year. Because of the MPR being so high, I can trust that it helps to capture more micro particles, such as pollen, bacteria, viruses and of course, all the pet dander that we have in the house. I also liked the fact that it proactively helps to proactively attract and capture all of the small particles into the filter to prevent them from circulating throughout the house. If you’re looking for your next filtration product, this air filter is wanted to try.

We started buying the Filtrete 1600 Ultra Allergen because we live in an area that produces lots of pollens, and we have a dog. We can definitely see and feel the difference with using this brand series and other brands. We sneeze less, and there's less dust. Our home has a fresh smell and does not smell dusty like some other places I have been. To make things even better, they are cost efficient. I won't ever change filters as long as these are available.

[This review was collected as part of a promotion.] I really like the Filtrete™ Ultra Allergen Bacteria and Virus air filter. It makes me happy knowing that I am providing my family an additional layer of protection from Allergens, illness, and all-around yucky air. It was easy to install and the material is very thick and durable.

[This review was collected as part of a promotion.] I suffer from allergies so I thought I would give these a try. I'm so glad I did because these work great. Since we started using these filters my allergy symptoms have lessened. I would recommend these if you suffer from allergies like me.

[This review was collected as part of a promotion.] I have tried several filter brands and most of them collapse after a few weeks. These hold up until it’s time to change them…every time. The filters are made well and catch everything it needs to. We change them every 60 days or so and it keeps the air quality decent in our home of 4 dogs. I will only ever use Filtrete filters from now on.
