Nordic Pure 20x25x5 Lennox X6673_X6675 Merv 8 Filter 4 PK

Please note that the actual size of almost all furnace filters differs from the nominal size printed on the air filter. To ensure the best fit, we recommend measuring your air filter for the exact size and comparing it to our "Actual Size". It's important to note that with the 4" and 5" air filters, there is a wider variance between the nominal and actual size depending on the manufacturer. Additionally, we offer 4 7/8 and 5 1/4 inch depth filters, which is why we ask you to compare the exact dimensions.

Our Nordic Pure 20x25x5 Lennox X6673_X6675 Replacement Pure Carbon Pleated Odor Reduction air filters are considered the traditional 5” filter with an actual size of 4 3/8”. These Pure Carbon Pleated Air Filters are made with a durable non-woven polyester base media infused with naturally derived charcoal, designed to eliminate odors in your office or home. Our pleated design provides three times as much carbon media per A/C filter while maintaining excellent air flow.

Manufactured using heavy-duty, moisture-resistant beverage board frame, our Pure Carbon air filters feature a metal mesh support grid for extra support. These activated carbon, odor eliminator Pure Carbon AC furnace filters can be used in residences as a stand-alone filter or as a pre-filter in high-efficiency commercial HVAC units. They effectively remove Volatile Organic Compounds (VOCs) such as chemicals from household cleaning products. For maximum odor control, we recommend replacing your air conditioning filter every 3-6 months.

The nominal size of our filters is 20 x 25 x 5 L x RED, with an actual size of 19 3/4 x 24 3/4 x 4 3/8 (19.75 x 24.75 x 4.38). Our filters effectively absorb odors, VOCs, and capture airborne particles from your indoor air. The improved pleated media provides 3 times the carbon media compared to flat panel carbon filters, without the mess of loose carbon particles from our carbon-infused media. Plus, our Pure Carbon air filters are proudly made in the USA.
