  • What buyers say about Filtrete 20x24x1, AC Furnace Air Filter

    They don't slow down my furnace in any way, if you are like me and prefer to have something delivered to your house rather than going to your local department store, then these are just fine and dandy.

    The Filtrete is cleaner than the old A/C units and the service tech commented on how clean the entire system is.

    I was surprised to find that all 4 filters were individually wrapped, that's not always been the case in the past.

    This is a very good product for the price and I would definitely recommend it to anyone.

    Air filters are inexpensive and can prolong the life of the unit. The Filtrete M 1000 is a medium quality filter which does an excellent job of filtering the return air to the air handling unit.

    Common Questions


    I don't see the orange 800s listed at walmart. Is this a different filtrete series?


    I am not familiar with the 800 series but I was told by a heating and air conditioning serviceman that the cheap blue filters do JUST.


    What is the reason for the price hike? It was in November of last year at $76 for the 6 pack. Now it is $107 sold and shipped by Amazon.


    Maybe get in touch with the manufacturer.


    Does the charged material produce and emit ozone?


    Please contact the manufacturer if you have any knowledge about this product.


    Is it possible that these are made in China?


    I think it's made by 3M, so I guess I'll guess at anyone of their manufacturing/ distribution centers.


    Does this filter have fiberglass in it?


    I'm not sure what the material is but it works well, even though it doesn't have fiberglass.
