Changing furnace filters--how often?
QUESTION:My wife and I are new homeowners and don't have a
clue whether it should be every couple weeks, months, 6 months,
whatever.
ANSWER: First, measure your filter, and next time you're
out shopping, pick up half dozen filters.
( they're cheap! )
then
During the heating season, get into the habit
of checking the filter once a month....
( first Saturday of the month )
If it looks "fuzzy", or dirty, change it!
I have mixed feelings about the newer
"pleated" air filters. They filter out more particles,
but they really reduce the air flow.
Unless your furnace fan/chamber is built to accomodate
pleated filters, I'd avoid them.
