CHICAGO — It seems like the array of IAQ products exhibited at the Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) just keeps getting bigger. Some products or companies may have not been there that were there last year, but new ones stepped forward to take their places.
From simple filters to ERVs and UV lights, IAQ manufacturers have been hard at work improving their products to get a bigger share of an increasing market, both residential and commercial.
