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.


Speaking only for myself, I'd use what is said by the home builder.
Try to keep the warranty?

Absolutely nothing to do with warranty.

My rule of thumb is never buy the cheapest or the most expensive.
Go with a known brand name. See what your furnace guy supplies - you
can likely source exactly the same filter for less than he charges -
Home Despot, Lowes, Cpstco, etc,


Amazon has Aerostar MERV13 filters, 4 for $34. I'll try them. They are
allegedly equal to the top name brands.
