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 current air filter and compare it to the "Actual Size" provided. This is particularly important for 4-inch and 5-inch air filters, as the exact sizes can vary significantly depending on the manufacturer.

Nordic Pure Honeywell Replacement MERV 12 air filters are a prime example of this discrepancy. These filters, which are nominally 5 inches thick, actually measure 4 3/8 inches in depth. Therefore, it's essential to measure your existing filter or the housing to confirm that the actual size matches the filter you intend to order.

Nordic Pure's pleated air filters are crafted using a heavy-duty, moisture-resistant beverage board frame. These filters feature a metal mesh grid bonded to the pleats, providing additional support. The filter media used in these AC filters prevents the growth of bacteria and mold, creating a healthier indoor environment.

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

The effective lifespan of your AC air filter depends on the indoor and outdoor conditions where you live. It's crucial to regularly change your furnace air filters, especially during any home improvement projects, to ensure fresh and clean air in your home or office. We recommend changing your air filter every 3-6 months to maintain maximum efficiency and economy.

Nordic Pure offers 16x25x5 MERV 12 Honeywell Replacement AC Furnace Air Filters. It's important to note that the actual size of these filters may be slightly smaller than the nominal size printed on the filter. Therefore, we advise measuring your existing filter to ensure the replacement filter fits perfectly. You may also want to consider our Honeywell replacement 16x25x5 filter, but be sure to verify the "Actual Size" before placing your order.

Nordic Pure air filters are made of an electrostatically-charged synthetic material that attracts airborne particulates, much like a magnet. These electrostatic filters help trap allergens, fine dust, smoke particles, plant spores, bacteria, and even some viruses as small as 0.3 microns. While our filters do not kill germs, the filter media is designed to prevent the growth of bacteria and mold, eliminating the need for potentially irritating chemicals.
