    Carrier fy4anf024 filter

    I have a Carrier FY4A system. It has a plastic air filter that is very porous. It seems such a filter would tend account for a good bit of dust in my home, so I have thought about replacing it. Problem is: I can't find any information on it.

    I have read that a HEPA filter isn't recommended as a general replacement, because of the air restriction the filter has. That made me wonder if there is a reason my HVAC has a filter that allows such unrestricted air flow.

    The entire product number is: FY4ANF024000AAAA

    The filter measures 16 3/8 x 21 1/2 x 1

    Can anyone educate me a little?
    I would appreciate any input on this subject.
    Thanks in advance for sharing your knowledge.

    Go to your local HVAC contractor and they will gladly help you find a filter that will fit your unit Ask them for a Merv 10 or higher filter.

    HEPA filters are a medical purpose filter usually only used in surgical or highly important server rooms. Not to mention that they are very very expensive.

    I would like a better description of the filter. Is this a 1" filter? It sounds like the sort of filter that is used with electronic air cleaners. There is a way to clean the other parts of such a system. They don't work without regular maintenance. If you haven't or don't want to do the maintenance, then as has been said, have a pro replace it with a box that will hold a 4" filter. Those last about 6 months and you can change them yourself. But they are expensive. (but an electronic one is very expensive)

    Here is a link to the unit:

    On page seven (top box, 2nd line from the bottom) is the dimensions of the filter.

    The filter has an aluminum frame around green plastic material.
    Indeed, while looking for something similar, I seem to have found the real thing:

    It is the 7th one from the bottom.

    Thanks. I didn't know that. And thanks for the Merv 10 tip.

    A 16"X20"X1" may fit. Might try that.

    16x20x1 won't fit without some mods to the internal rack, they just fall into the plenum or get sucked up into the coil. Unfortunately you're stuck with the hog's hair washable filter unless you:
    a) modify the air handler
    b) install a filter rack external to the air handler, or
    c) get a case of filters custom made
