I could buy 3 MERV 11's locally for the same as these 6 MERV13. Better filtration at a lower cost.

These air filters work great. This is my second order and I can't find any filters in any of my local stores at a MERV13 rating at this price. They ship extremely fast!!

Just purchased my 2nd order of pleated Merve 13 air filters. The 1st order did a great job filtering the air this past winter in our farm house. We supplement our furnace with our wood stove. Our indoor air was kept very clean! Thanks
