    Default AC Filter

    We need a 20x30 filter for our central air. They seem to range in price from $3 to $30 and up.
    What should I be looking for and is there one brand better than the next ?
    Is a HEPA filter necessary ?

    Thanks for your time.

    A pleated filter gives the best filtration.

    I don't personally believe that HEPA filtration for a furnace is either effective or necessary.

    Not sure if this makes a difference in your answer but this is for a central air not a furnace. The central air in our house is separate from out boiler.
