Good price on 3m furnace filters?

What's generally a good price for 3m furnace filters? Standard dimension ones 25 x 6 x 1 I think it was at 1000 micro allergens.

I know they go up in price for higher micro allergens but I have no pets or allergies in the household to be concerned with

3M 1000 is roughly a MERV 11

Most HVAC guys recommend MERV 8 for good air flow. I suggest a MERV 10 and change your filters every two months.

For the price of a 3M (generally $15 each, $10 on sale), you can get 4 decent filters at FurnaceFilters

You're in the west end. You can pick up from

MERV 8 is $45 for a case of 12
MERV 10 is $50 for a case of 12
MERV 11 (3M Equivalent) is $58 for a case of 12

I still like the Nordic pure filters on amazon, specifically their merv 12 with carbon. Prices are great if you can find a deal. Use camel camel camel to set a price target
