    Filters

    What is the best filter for whole house unit. A lot of talk about different ones and there are a lot of different ones. Hope you do not consider filter change a diy. I know some units are limited to thickness.

    Thickness
    Merv rating (some use different rating 3 M)
    Material
    Flat or Pleated

    Thank You

    Not much better than a 5" media filter, if your ductwork will accomodate.

    If this will be a new install I would suggest a 4" pleated filter 7 or 8 MERV rating. Glasfloss makes great filters, the ZL line is a good start.

    Sorry to resurrect this old thread, but I have been searching these threads for awhile and cant find my answer. I have a 355mav evolution with 4" media filter. I had always though that the higher the "merv" value, the better. I bought a Honeywell Merv 12 Ultra filter for my next filter change. Will that have the possibility of restricting the airflow too much? Should I stick with the 7-8 merv range to be safe??

    With a 4" deep filter, you are safe with a high MERV rating. It is the 1" filters that much more restrictive.

    Who are you posting to and what are you referring to? Carbon filters are usually partial charcoal filters for odor control that are placed after the dust filters.

    Nope. Unless the duct system was sized for one. Bad thing to use.

    How many times must one fix something before it is fixed?

    Should have a Pro check the static of the duct system.

    Higher merv is generally more restrictive(higher static)!!
