Atomic Filters are great they were ordered and the turn around was within a week. I recommend Atomic Filters to my family and friends

This is the only filter I have found that fits my air handler. I take away one star because some of the cardboard finger tabs between the filer's pleats always need to be pushed into place. Otherwise, the overall condition of these filters has been fine and fits & performs well. I like the service & support from Atomic Filters.
