AAF Flanders EZ Flow 20 in. H x 20 in. W x 1 in. D Fiberglass 4 MERV Air Filter (Pack of 12)

these work well

Hoping it will work as advertised

My heat and AC guy said the expensive filters can cause premature failure of the air handler fan motor and he said he uses the fiberglass ones at his house. Good enough.These are well built and I've used one so far. I replace them every 400 hours on my thermostat timer.I like the Flanders brand. They do the job.

Furnace and air handler filter

These definitely seems cheap, and you can see right through them. Part of me wonders if they do anything at all? But that was the MERV that was recommended.

Change every 3 to 4 weeks bc we have a dirty beach road and hairy critters. Recommended for the new Carrier system in our remodel.

This is my second order of a years supply. Good value for money.

AC Filters are one of the most misunderstood functions in a household. The fancy ones are too thick/dense and don't allow for proper airflow. Buy these cheaper ones and replace every 3 months....your system will last longer, you will get better heating & cooling and airflow is not restricted. They do the job, catching the dust, and no filter actually filters out micro particles without restricting the main thing your system needs....air!
