Great air filters.

We switched from the generic filters that came with the new build and switched to these. I'm glad I did. Filters so much more and keeps the house without odors. I would never use a different air filter ever again.

Nice Filter

Nice filter, it's hard to find these locally at a fair price. Shipping was fair and I received the filters quickly. The price even beat out Amazon. I also know that these are a quality filter. Thanks Honeywell.
