It's $39.99 at my costco which equates to ~$13.33/filter and that doesn't include the driving and tax.
They are the ultras posted by the OP.
yup, they're the ultras @ costco, but my costco only has 2 sizes that don't fit my furnace.
Quote from i3ighead :
I need some cheap 20x20 1 inch filters for our office. The AC guy recommended that I use the crappiest of the crappiest filter unless I have allergies. I dont really have any so I just want one that will not stress the AC which will increase the electric bill. Any advice on where I can buy them in bulk? Thanks!
you should be able to pick them up in bulk in any hardware store. they usually have boxes of a dozen or so.
