Review on Flanders PrecisionAire 24x30x1 Naturalaire Standard Air Filter (Pack of 6) by Steven Lewis

Great filter for the price. I have an unusually large 18 x 30 x 1 return air filter at home, so it's not easy to find commercially. If I'm lucky enough to find one or two at Walmart, they're $16 each, not a bad price for a 3M 9 Merv Filtrete. But they cost $5 each and are identical in design except for a small difference in size. And if I change the filter every two months, I'll have a year's supply! This NaturalAir filter works a little less than Filtrete. It is 16 inches shorter on the sides and 16 inches thinner than the Filtrete. This wasn't a problem for me as it was still filling the filter frame that was installed on my air conditioner.
