Nordic Pure Lennox X6673_X6675 Replacement Merv 8 Filter

Almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. It is best to measure your air filter and compare the exact size to our "Actual Size" specifications. With 4-inch and 5-inch air filters, there is often a wider variance between the nominal and actual size, depending on the manufacturer. We also carry 4 7/8-inch and 5 1/4-inch depth filters, which is why we recommend comparing the exact dimensions.

The Nordic Pure 20x25x5 Lennox X6673_X6675 Replacement Pure Carbon Pleated Odor Reduction air filters are considered the traditional 5-inch filter, but have an actual size of 4 3/8 inches. 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 airflow.

Our Pure Carbon air filters are manufactured using a heavy-duty, moisture-resistant beverage board frame. There is a metal mesh support grid bonded to the pleats for extra support. These activated carbon, odor-eliminating Pure Carbon AC furnace filters can be used as a stand-alone filter in residences. They can also serve as a pre-filter in high-efficiency commercial HVAC units. They remove Volatile Organic Compounds (VOCs), such as those from household cleaning products.

For maximum odor control, we recommend replacing your air conditioning filter every 3-6 months. The nominal size of these filters is 20 x 25 x 5 inches (L x W x D), but the actual size is 19 3/4 x 24 3/4 x 4 3/8 inches (19.75 x 24.75 x 4.38). These filters effectively absorb odors, VOCs, and capture airborne particles from your indoor air.

The improved pleated media in our Pure Carbon filters provides three times the carbon media compared to flat panel carbon filters. Unlike some carbon filters, our products do not have messy, loose carbon particles, as the carbon is infused into the media. These filters are proudly made in the USA.

In summary, it is crucial to measure your air filter and compare the exact size to our "Actual Size" specifications, as furnace filters often have a different actual size than the nominal size printed on the product. Our Pure Carbon Pleated Odor Reduction air filters offer superior odor control, VOC removal, and airborne particle capture, while maintaining excellent airflow and durability. For best results, replace these filters every 3-6 months.
