[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.

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.] These filters are really nice quality. They are slightly thinner than the ones we have been using for years, but I feel they do a nice job. There’s less dust throughout the house with these. They were super simple to install. No problems!

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 have tried so many filters, but nothing worked like 3M - Filtrete™ Ultra Allergen Bacteria and Virus. It's perfect for my home, with a dog that sheds everywhere and little ones, i needed the right filter to keep virus and bacteria away! very pleased with the results, i got a whole bunch to cover the whole house. Great quality and efficient for sure.

[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.] 3M Filtrete Ultra Allergen Bacteria and Virus air filter makes the air in the house feel and smell cleaner. I feel comforted that the filter removes bacteria and viruses. Built well and easy to install.

[This review was collected as part of a promotion.] I have used the "entry level" (inexpensive ones) 3M filters in the past and didn't have a problem with them. So I thought I would splurge and get the one that lasts for 3 months instead of the monthly ones that I have used. This did not disappoint, the quality is superior in comparison to the competition that is out there. Plus easier to change every quarter than monthly.

[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!
