  • What buyers say about Flanders E-Z Flow Heavy Duty Air Filter, MERV 4, 20 x 20 x 1-Inch

    The product fits perfectly in our a/c unit and is good for a year or less. We are saving a lot of money because we discovered these.

    The filters are designed to protect the motor of the unit, not keep the air in the house free of pet smoke and dirt. I used to have a cat, and the filter had a lot of cat hair in it.

    The filter media is not what you see, it's white, not blue, and I still get emails about ordering white filters at a lower price.

    I decided to buy the cheap ones by the case and change every 30 days after he said it was best to do that.

    Good quality is what they get with the job done.

    Common Questions


    Do you have to change the filters more often since they are not as thick?


    I bought the more expensive filters in the past, but I decided it was better to have a "thinner" one.


    Is it possible for them to change out air filters during the 1 month period?


    They should be changed once a month to prevent dust build up in the unit and freeze up your system.


    Which one of the two pics is included?


    They fit the central air condition in the ceiling and are free shipping.


    What is the difference between 10255.012430 and 10155.012430?


    The pictures sometimes do not convey that 10255 has the metal mesh on both sides of the filter, while 10155 only has it on the downstream side.


    What is the Merv rating?


    The Merv rating allows different sizes of particles through the filter, but it depends on the manufacturer's rating.
