2 pcs fits the budget
Accumulair Diamond 21x23x1 (Actual Size) MERV 13 Air Filter/Furnace Filters (2 pack) the original filter size that came with my AC is 21x23.5x1, which I think is MERV 4 or even the lower scale. It's too soft and sometimes felt on the ground and left my whole house without air filtering protection. So far this filter is the best, though in specs is a bit smaller. Actually the size fits and the quality seemed to be hard and good. Similar products cost between $19-$24 at Home Depot website from Honeywell, which almost double in price! Two piece package is good. Other brands on amazon have matching price, but you have to buy 6 near $60-70.

Great option for hard to find size
Didn't realize the size I needed was such an oddball but after looking found this and it looks great especially for the price. Seems as nice as the 3M ones I used to get for previous system at a similar price. Seem to be flaky on availability but hopefully when I need to reorder they'll be available again.

What a difference
I need to change the a/c filter I have been to walk mart, Kmart, Sears, target and couldn't find my size at these stores. When I found it on here and the 1e rating I was like YES. Got it home fit perfect and the air quality is so much better I bought a pack of 2 which is great plan on buying more next year

Filters, wiring and/or casing were crushed
Because both of my filters are crushed I am not looking forward to trying to change the filter within 3 months. It took forever to try to force it inside the air handler...kept snagging due to the paper casing being crush as well as the wire casing. The Amazon box was not crushed, but the filters were were...have pics if necessary. Not very happy at all...I'm hoping I'm getting the full benefit of the air efficiency. Due to the damage, I'm just not sure that I am.

Just as described
The product fit perfectly, and we have one of those new funky air handler systems. Will order again.
