not bad

Not a bad price. I get 2 uses out of one package for my air purifier. I would not say it lasts 3 months though.

Love this pre-filter

I actually use this with my Whirlpool air purifiers because they're thicker and can easily be cut to size. This cuts down on the gunk actually getting to my hepa filter much more than the regular pre-filters recommended by Whirlpool.

Honeywell 38002 Envirocare Universal Replacement Pre-Filter

Product received in a timely manner and meets advertised specifications. Would purchase again thru amazon.
