One of the most environmentally friendly filters on the market - fiberglass media is free of inks, dyes, resins, adhesives, binders, chemicals, and additives while frames use partially recycled materials, water based adhesives, and very little ink
Constructed without sharp metal so they're very hand friendly - no gloves or special handling required
Doesn't support microbial growth so they're a great choice where bacteria is a concern
Rated UL Class 2 by Underwriters Laboratories
