Bought first one in October 2014... 3 adults, a 1 year old & 4 dogs live here so I wanted a good filter. I saw them on a home show so I tried them now they are the only ones for us. I am a 65 year young grandma & clean air is very portant especially for my grand-daughter. Love your product. Thanks Kathy Alexander

We've been using Filtrete Ultra Allergen Healthy Living filters for the past three and a half years. They keep our house literally dust free and fresh. We have two cats as well and appreciate the advantage of having good filters in our furnace that we change every three months.

[This review was collected as part of a promotion.] I have used this 4" filter since replacing our furnace (used 1" Filtrete filters before this). Love how it cleans the air, especially since we have 2 Balinese cats. The only "con" about this filter is how hard it is to remove from the furnace. I finally figured out a way to attach a string to the front of the filter so that it's an easy pull-out when it needs to be changed. Perhaps Filtrete could come up with something like this, or 2 finger holes for easy removal.

[This review was collected as part of a promotion.] This is absolutely the best air filter I have found for my home. We had some minor construction in our kitchen, Sheetrock, taping and sanding. Dust was everywhere. Installed one of these Filtrete Healthy living filters and the air quality improved within minutes. I change my filter every season, the Healthy Living filters trap so much dust, dander and who knows what else. Great product worth the price!

Filter says 16x25x4 but it is actually 4.25 thick! Does not fit in my furnace which is exactly 4.0" This is an extremely frustrating problem and every store carries the new 4.25 filter and apparently nobody makes or carries the old 3.75's anymore. I could cram a 4" in there but not one thats 4.25. Trust me, I tried.

I have started using these filters because of my severe allergies that hit me every summer. This past summer I thought would be a bad allergy season because of all the rain we had earlier in the spring. However I actually felt better all summer and it has to be because of the Filtrete filters that I have stared using. You have a customer for life.

[This review was collected as part of a promotion.] I just replaced my furnace this last month and decided to go with the new upgraded system that included a 4" filter. Due to where I live and having open fields by my home my filter gets dirty very quickly with the wider filter I do not have to change the filter as often as the smaller one.

First two both said they were locked and I need to contact service. I didn’t want the hustle. Then it paired. A month later I checked it and not working again. Pulled the filter. It needed changing. Like first onr it wouldn’t pair. I am technically advanced. It should not be complicated. The online account only wanted my email, no password. I don’t like that. Good idea that has more work needed

[This review was collected as part of a promotion.] I have been using this filter for many years! We used to buy the cheap filters and had a constant dust problem in our house. Since using this filter there is no longer a problem! The old saying "you get what you pay for" certainly applies here. Well worth the money for a clean healthy home!

I bought this product because it was the right size to replace my Electronic Air Filter, that had died. I installed it and all seemed well. After about 1 month I noticed the A/C unit was running continuously and the temp in the house was going Up. I noticed that very little air was coming out of the vents. Turns out that the filter material had sort of Swollen-up and cut the width of the 'pleats' by more than half. Basically, it was like having a 30-day filter in your furnace for a year! After de-frosting the unit and mopping up all the water, all is now normal with a different filter. I would like my $30+ back please!
