[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!

[This review was collected as part of a promotion.] I absolutely love this filter I have noticed such a big difference in my air quality. I love that it filters out allergens and also bacteria. I noticed less allergies since I changed my filter! I definitely recommend this filter!

[This review was collected as part of a promotion.] I think these 3M filtrate filters do a good job of filtering out allergens in my home. The filters are extremely well-made and easy to install. The material and shaping of the filters make it look like they would do a great job and filtering out the allergens. I’ve already noticed less dust particles in my home as a result of using these filters.

[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.] After having the Filtrete Ultra Allergen Bacteria and Virus filter in use I have defiantly noticed a difference in the air quality. it seems to be getting all the nasties and odors out of the air! It is well marked for installing and went it well.

[This review was collected as part of a promotion.] I can’t say enough good about this filter. Since using it I’ve noticed a difference in my allergies and quality of air. I feel like I can breathe better and don’t wake up congested as I usually do. I know it’s working for my air purifiers that I keep running throughout my house show that my air quality has improved. These are definitely my new go to filter going forward. I definitely recommend!

14x14 is what I always use but the new ones I bought today are 1/4 inch both ways too big and I cant push it into filter holder. I only use this brand and have never had this happen before. I always give top rating but unless you rectify this made too big for 14x14, I will withhold changing my rating to see how you fix this.

[This review was collected as part of a promotion.] I got these filtrete ultra allergen filter and it works great. It seems to keep the air clean so far and they were very easy to use. So far so good. Will definitely recommend to everyone to go out and purchase for themselves
