These Eco-Aire filters are constructed using a MERV 7, patented fiberglass and are encased in the same partially recycled cardboard frame as Eco-Aire pleated air filters. Unlike other brands of disposable filters made with sharp metal, these will not cut your hands. Eco-Aire disposable filters are simply the finest disposable fiberglass filters available in the industry today.
Each filter lasts up to one month and should be changed and disposed of regularly. A 12-pack will provide up to a year's supply of cleaner air.
