Great price for these filters. We have been using them since we moved into our newly built home 2 1/2 years ago.

Thought this was a great price since I usually pay $35 For one. But these are not 4 like it says . They are 4.5 did not fit ! Now I have to return them.

We have purchased a new home in Washougal, Washington. The home inspection revealed very dirty filters in each of two furnaces. We have specified Filtrete furnace filters to replace the very dirty generic filters as part of the purchase agreement because we have used them exclusively in our current home for about seven years. They seem to help with our allergies! 3M makes great products including your Blue masking tape and air filtration face masks which we have used when mowing the lawn!

We bought a new furnace 10 years ago and didn't like the flimsy filter that the company provided. I researched filters online, in particular for old homes with pets, and found this filter. I am happy when I change it and find all sorts of particles, large and small, that have been caught in the filter.

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

I was using the regular version of filters and they worked but weren't the best for our house. I switched to the healthy living ultra allergy filters and they have helped so much! I live in the desert with two large dogs, a husband with lots of allergies and tons of dirt and dust! These are definitely helping a lot more! It feels good knowing I am helping my family stay healthier!

I did buy this a few months ago because I like to have them on hand when needed. I buy this even though the guy who worked on my furnace and replaced the blower motor said not to use these filters. He said they were the cause of the blower motor going out, because they would have to work to hard and need replaced. But these filters, I believe, do what they are suppose to. I have dog's and these filters help me breath better when the air conditioner for summer or heater for winter.

I use 16x20x4 inch MERV 12 filters from Filtrete because they have the best build quality of all the filter brands I have used. I just have an issue with the vague MERV rating for a particular filter. Filtrete uses their own rating system (1550 for example) and then I have to do some research to find the MERV rating.

After my electronic air filter system failed, I decided to to try the Filtrete Air Filter. (1550, 4"). I have been using it for the last four years. It seems to work every bit as as well as the expensive electronic system. I thought we would notice more dust in the house, but that is not the case!!

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
