Furnace filters
For the first time in 53 years of owning homes, my new house has a
furnace and uses filters. It takes a 1" filter.
I see prices can vary considerably but is a MERV 8 and MERV 8 regardless
of the brand? Should I use MERV 8 or MERV 11? We have no pets.
I see filters with MERV 11 rating from $9.95 ($7.45ea by a dozen) to
$14.50. Any real difference if they have the same rating?
Discount filters seems cheapest.
