Filtrete Furnace Filters
The Filtrete™ brand furnace filters are manufactured by 3M Corporation, a US company with worldwide affiliates.
Filtrete's Corporate History
The company was founded in Minnesota in the early 20th century. It came to be known as the Minnesota Mining and Manufacturing Co., thus the name "3M".
There are several Filtrete replacement filter models with minimum efficiency report value (MERV) ratings of 8 to 11. MERV ratings tell consumers how effective a filter is at trapping particles that are sized from 1 to 3 microns. The higher the rating, the better the filter. They feature a pleated electrostatic model as well as disposable designs made from polyester or fiberglass that should be changed every two to three months. They also make a washable, reusable filter, designed to last several years.
You can purchase them at home stores, hardwares, grocery, and large all-purpose stores. Prices range from about $6 to $22.
Filtrete Furnace Filter Warranty
There is no warranty on these filters. If you encounter problems, contact the customer service department of the retailer you bought them from.
