This is a great deal. When you can buy QUALITY furnace filters for less than half price of your local retailer, then you've found a great deal.

Proof is in the pudding

I purchased two filters on February 18th. I've used the competitor's filter in the past, but when I ran across this brand online, I decided to give it a try. I am elderly, live in an apartment that is old (but well maintained by maintenance) and have a history of bronchitis due to allergies. I wouldn't have purchased these filters had I not been impressed with the details stated. . In short (or in long), I feel very good about my decision to purchase. So far, so good.

from traditional cheap ones to top of the line. They only last a week or two but you got to keep buying. The buying process is nice and having it auto shipped is great.
