Re: Furnace filter

I use these filters 16x25x4 in my new carrier furnace and have found a case of 5 honeywell merv 10 filters at pex supply ****** for $104.95. So far for a name brand filter that seems to be better quality than the carrier merv 8 filters I was buying at $35 each from a local supply co. My furnace tells me when to change them, the default is set to 90 days, and measurers static pressure daily, and the filters do not seem that dirty, so I have gone to 4 months so far on current filter, also my local home depot has started carrying honeywell merv 8 filters in a 2-pack for 29.99. Thats only $15 each so you might want to give them a try if your have a home depot locally. These filters are expensive ,but the new high efficiency furnaces are expensive too so I guess it is all relevant in better air filtration. Good Luck!

Re: Furnace filter

Every Installer should have a checklist or report on the operation of there new furnace. On this checklist should be the allowable temp. rise by the manufacturer and the actual rise found by the installer. The homeowner should be given a copy of this for there records, at least that's what I have always done.
