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 have used these filters for years. They say they are good for the whole year, though I still change mine out every 6 months. Ordered through Walmart as they were the only place I could currently find them amidst all this COVID crap going on

I have used this filter since 2000. It is the best! I have two cats and and it removes the dander wonderfully. Only problem is that not all stores sell my size so I purchase 4 to 6 at a time.

Used the Filtrete 2200 1" MPR filter until we had the furnace/air conditioner system replaced last year which has a 4" filter but the Filtrete 4" filter maximum filtration is a 1550 MPR...wish it came in the 2200 MPR.

Expensive but lasts a long time...not the twelve months it says in the ad. We change every three months but we live in the South for the air conditioner runs a bunch.

[This review was collected as part of a promotion.] Love this filter, I use it in my apartment and I tell how crisp and clean the air is when my a/c is running

This filter was restrictive enough to cause my evaporator to start icing up. Should be labeled that a HVAC technician needs to adjust refrigerant charge or up the speed tap on blower motor.

Space between rails in Lennox furnace for their 5” filter is only 4 7/16”. The filtrete 5” filter is 4 11/16” thick. Going to try filtrete 4” filter that is 4.31” thick.

[This review was collected as part of a promotion.] I've purchased this filter for 4 years now, ever since I moved into my new house. I like it because it performs well and as expected.

I usually have used these in the past and recently purchased a different brand. I prefer these. They are better constructed and appear to better clear the air.
