Filters don't last long at all

I've had to change my filter 3x in 1 month, because it kept clogging and causing my furnace to short cycle. I keep a very clean house, have 1 dog and 1 cat, a separate air purifier and vacuum regularly...shouldnt have to change out a 90 day filter 3x in 30 days. Very frustrated with this filter and will be calling to get my money back.
No, I would not recommend this to a friend.

Excellent filters

Been buying these for several years now, 1085 or 1085D, and wouldn't go elsewhere. We change every 4 months and they're catching everything we need them to.

Allergen Defense Air filter does not fit !!!

I was using Filtrette Clean Living filters for years and was happy with its performance. Having read about the higher filtration levels of Allergen Defense, I decided to order this one for my 20X25X1 opening of my AC unit. To my surprise I was not able to fit it into the hole into which the Clean Living filter entered easily. The Allergen Defense is taller than Clean Living filter of the same posted sizes 20X25X1. Please advise what could be done. Thanks!

Do not buy
on March 25, 2019

I bought this filter for my furnace and noticed furnace won't quit running. My furnace ran constantly for 2 days until I find out from the technition that this 3M filter is made too thick for smooth air flow, which will make the furnace work harder to compensate. The issue was solved as soon as changed with a different filter.
No, I would not recommend this to a friend.

Great Disposable Filters

Been using the 20x25x4 for multiple years now. Filters work great, I replace mine every 90 days in my house. Never had any issues or concerns about quality or construction of the filters.
I've seen many complaints about the 1" thick filters and while I understand their concerns; a 1" thick filter is old technology and should consider getting a larger filter box.
I find the complaints about the tabs holding the pleats in the filter where you may have to push a few back trivial. You're buying a MERV 11 equivalent disposable filter, again DISPOSABLE. It wasn't long ago when everyone was just using the blue fiberglass air filters.. There is a balance between retail cost and manufacturing cost. If they raised prices to appease everyone, they'd complain the filters are too expensive even though build quality is excellent!
I would recommend this to a friend!

Because you have to breath

[This review was collected as part of a promotion.] I love 3M Air Filters! No other filter has ever made it so much easier for me to breath through the height of allergy season. I always know when it's time to change the filter because I wake up all stuffy in my sinuses, with the 3M Filters I can have 3 full months before I need to change the filter, with other brands I was lucky to get one full month. I like 3M products and find that the majority of the time all of their products are extremely well made and of excellent quality.

Good quality

[This review was collected as part of a promotion.] I bought this because I wasn't satisfied with the flimsy green filters we were getting. This filter seems to "grab" a lot more than what the cheap ones did. I just found out that my toddler son has many environmental allergies so I will be getting the higher grade Filtrete filter when this one is ready for replacement.
I would recommend this to a friend!
