The White-Rodgers 4-inch media air cleaners are a premium upgrade over standard furnace filters, but still offer convenience and simplicity, helping to minimize unnecessary callbacks and provide contractors with a simple solution for homeowners, says the company. According to the manufacturer, they have standard MERV 8 filters that capture allergens up to 20 times more efficiently than ordinary fiberglass filters. This solution also offers contractors time-saving, simplified installation with factory-punched screw and drill access holes already in place in the heavy-duty, 20-gauge galvanized steel cabinet. The snap-on ABS plastic door offers easy filter replacement without tools. It is available in four standard sizes. MERV 11 filters are optional.
