12x20x1 filters are 1/2" undersized! (see the photo). As a result, it fits very loosely in the filter slot. 3M and other brands filters fit tight in the slot. Also the filters are unmarked (see the photo). There is no way to positively identify that they're MERV 10, not other lower ratings.

Great Product at a GREAT price AND free Shipping.. what more can you ask for?....
No reduction in air-flow with these filters, even at a merv 10. Seems to filter the air very well as my wife has allergies and seems to do a lot better with the merv 10. There is one small draw-back.. when you first use a new one some of the filter fibers get carried in the air, you WILL notice this on you glass tables, but the benefits far out-weigh having to dust a table top a few times a week.
