Great filter! a few pointers...
I ordered these filters because my hvac guy wanted $150 to come switch out the filter. This was soo much cheaper! Also, my old filter had plastic "pleat spacers", and with this new one I didn't seem to need those anymore, it holds together on its own. Incidentally, I found out MERV 13 is a very high filtration, suitable for hospitals; I probably could have gone a bit lower in MERV, which is cheaper. Still, all in all a good deal.
