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.

Trouble is, they don't have efficiency rating on air flow drag.
