Refined and Nordic Pure MERV 12 Pleated Air Filters, 16x25x4 Inches, 2-Pack

It's crucial to note that almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. To ensure a proper fit, it's best to measure your air filter and compare the exact size to our "Actual Size" offerings. This variance is particularly pronounced with 4-inch and 5-inch air filters, as the difference between the nominal and actual size can be wider, depending on the manufacturer.

For instance, if you're replacing a 4 3/8-inch depth 16x25x4 filter in your Honeywell unit, you should order our 16x25x5 Honeywell Replacement air filter that measures 15 3/4 x 24 3/4 x 4 3/8 (15.75x24.75x4.38).

Nordic Pure's 16x25x4 Pleated Air Filters, rated at MERV 12, are crafted from electrostatically charged synthetic materials that effectively attract and capture a wide range of airborne particulates in your home. These high-quality pleated air filters feature a heavy-duty, moisture-resistant beverage board frame, with a metal mesh support grid bonded to the pleats for added strength and durability.

MERV 12 furnace air filters are comparable to HVAC filters with an MPR (Microparticle Performance Rating) of 1500-1900. This high-performance HVAC replacement filter helps maintain the efficiency of your air conditioning and heating systems, ultimately saving you money on utilities and costly maintenance.

It's crucial to regularly change your furnace air filters, especially during home improvement projects, to ensure fresh, clean air in your living or work space. We recommend changing your air filter every 3-6 months to maximize efficiency and economy.

Particles in indoor air are measured in microns, with a human hair being approximately 100 microns wide. Nordic Pure air filters are designed to capture airborne particles as small as 0.3 microns, providing superior protection against allergens, fine dust, smoke, and more. While these filters do not kill germs, the filter media prevents the growth of bacteria and mold, eliminating the need for potentially irritating chemical additives.

Nordic Pure air filters are crafted from an electrostatically charged synthetic material that effectively attracts and traps airborne particulates, safeguarding your family from allergy-triggering pollen, dust, smoke, and even some viruses.
