[This review was collected as part of a promotion.] I received a 3M - Filtrete™ Ultra Allergen Bacteria and Virus 1600 MPR 1600 16 in x 20 in x 1 in.n It is the perfect fit, nice and tight. It is a very sturdy filter, and looks so different than the filters I have been using in the past.

[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 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.

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.

Love the quality of this air filter ! Its very sturdy on both sides.
