Review on Airity Replacement Compatible Pre Filters Pre Filter by David Dortch

First, the activated carbon filters are not the same size as Honeywell A filters. Honeywell A activated carbon filters are 10.7 x 7.4 inches. These filters are much larger, so be aware that you will scale them down. In addition, these activated carbon filters - if they are actually activated carbon filters - are definitely NOT made of the same material as Honeywell's activated carbon filters. Honeywell filters are thicker and stronger; This material resembles a thin black mesh - cheaper in all respects and less effective in my opinion. Save your money and buy direct from the manufacturer - unfortunately I only bought them because they are in stock at Honeywell and seem to last forever. But I will not use this material.
