  • What buyers say about HVAC Air Filter; Lasts a Lifetime


    I can see how efficient this filter is based on inspection of the filter element, Lifetime guarantee means I don't have to worry about buying another filter, which will save me a ton of money over time.


    I contacted K&N sales and requested assistance on the additional sizes, but they are still waiting for a call back.


    The construction is great and the element surpasses any other reuse unit on the market, what more could you ask for? My intake vents bend into place better than the cardboard version, and the sturdy frame actually locks into place better than the cardboard version.


    The cheapskate in me loves the idea of a house filter that can be washed out in a day and can be paid for in a year.


    This filter will save me money in the long run, because I won't have to go to the store to buy more filters.

    Common Questions

    Q:

    Do you need to use their spray to clean the filter?

    A:

    I have the 20x20x1 version which is the same but just a different size. They say you should use the cleaner spray, but I don't think so.

    Q:

    What is included in the limited lifetime warranty?

    A:

    It says on the box lifetime warranty that it is for 10 years, but then it falls apart and should we be worried about it for the seventh or eighth year?

    Q:

    Is it in 14x14x1?

    A:

    I went to their website and found that the size they were looking for was not in their inventory.

    Q:

    Did this K&N work or not? Our furnace has a 20x 24x4 filter.

    A:

    It depends on the tray, if it has a single tray bracket, it should work.

    Q:

    Is the filter flexible because of the access to my furnace? Is it possible to slide it in horizontally because of the access to my furnace?

    A:

    No, it is a stiff plastic frame.
