  • What buyers say about Flanders PrecisionAire


    I was able to tell the difference between the old and new filter quickly, and I have not had any issues with the item falling apart or causing problems with the heat pump/air conditioning system.


    These are some of the best air filters I have ever used, and they are very easy to clean.


    They don't tear apart once used, they only last for 2 months, and my A/C change filter started to blink after that, but I'm happy with the purchase.


    I am happy with the price and the packaging of the product, and would recommend it to anyone.


    At first glance, these seem to be the same quality as the branded ones but at a fraction of the cost. I will probably end up buying these going forward if the product doesn't meet expectations, but I will update the review if I do.

    Common Questions

    Q:

    I was delivered bent, what is the return policy?

    A:

    I would call them, but I don't know. Amazon is good with damaged returns.

    Q:

    Is it possible to tape the filters on a 20 inch box fan?

    A:

    The filters have a cardboard frame to tape to, so I don't see why it wouldn't be possible.

    Q:

    The aircondiner filter is 25 12 x 15 38 x5 14 inches.

    A:

    That would be a custom size filter, you could call an air filter supply house and inquire about custom filters.

    Q:

    Do you carry a 20x20x4 inch filter?

    A:

    The brand is terrible and should not be avoided by reading the reviews.

    Q:

    What side is up and what side is down?

    A:

    The side of the air filter has an arrow that tells you.
