Nordic Pure 20x25x4 Pleated Furnace Air Filters, MERV 10, 2 Pack

The Nordic Pure 20x25x4 Pleated MERV 10 Air Filters are designed for residential heating, ventilation, and air conditioning (HVAC) filtration. This 2-pack features pleated filter media made from electrostatically charged synthetic materials that attract and capture most airborne particulates in your home. The filters are made in the USA and feature a heavy-duty, moisture-resistant beverage board frame with a metal mesh support grid bonded to the pleats for additional support.

With a MERV 10 rating, these Nordic Pure filters provide advanced HVAC filtration for mid-sized airborne particles and pet dander. The product listing states that Nordic Pure MERV 10 is equivalent to MPR 1000 and describes these filters as comparable to HVAC filters rated MPR 900–1000.

Before purchasing, check the actual dimensions of your existing filter carefully. The nominal size is 20 x 25 x 4 inches, while the actual dimensions are smaller. Matching the actual size is important for ensuring the replacement filter fits your system properly.

It also emphasizes regularly changing furnace air filters, especially during home improvement projects.
