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.

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

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 like that this filter helps asthma & allergy suffers because this is certified for these ailments. I like that this filter should be changed every 3 months. The only thing I think to improve would be to have the filter last for 4 months. This filter easy to install and remove.

[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 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.] This is just a furnace filter. But it's really good quality and fit perfectly into my furnace cabinet. I'm not sure how I'll be able to know it works well other than waiting for a month or two to pass and understand if it works. I would think if it shows up dirty then it works!
