Full Product Details
Nordic Pure Half Inch Ring Panel AC Furnace Air Filters consist of an internal frame bonded between flat layers of two different types of electrostatically charged HVAC furnace filter media. The first layer is a high-capacity, polyester filter material which acts as a pre-filter, capturing large airborne particles. The second, more efficient, layer is a MERV rated smooth poly-blend filter material. The electrostatic charge works as a magnet to draw in and trap smaller airborne particles. In combination, the half inch (1/2″) double media air filters provide exceptional air filter capacity and remarkable efficiency.
We special order the internal frame for the half inch furnace filter, so please make sure you order the correct size. The Actual Size listed above is the exact size of the metal frame. The AC filter material extends beyond the frame, which is 9-gauge wire grid with a support that runs through the middle for added strength and stability.
Half inch ring panel furnace air conditioner filters are especially great for apartments, campers, boats, buses, RVs, AC and heater window units, and any air system that requires half-inch (1/2″) air condition filters. In our opinion, this double-media half inch air filter is even more effective than a half inch pleated air filter. With its two layers, it does double-duty! We offer almost any size half inch A/C air filter you are looking for, along with a 30-day money back guarantee.
Important Note: Almost all furnace air filters have a different Actual Size (the exact dimensions) than Nominal Size (the name). It is best to measure the exact size of your A/C filter and compare it to our Actual Size to be sure your HVAC replacement filter will fit!

What are filter MERV ratings?
MERV ratings are Minimum Efficiency Reporting Values, or MERVs, report a filter’s ability to capture larger particles between 0.3 and 10 microns (µm).
This value is helpful in comparing the performance of different filters
The rating is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE). The higher the MERV rating the better the filter is at trapping specific types of particles.
Average Particle Size Efficiency in Microns
MERV Rating / Efficiency
1-4 / 3.0 – 10.0 less than 20%
6 / 3.0 – 10.0 49.9%
8 / 3.0 – 10.0 84.9%
10 / 1.0 – 3.0 50% – 64.9%, 3.0 – 10.0 85% or greater
12 / 1.0 – 3.0 80% – 89.9%, 3.0 – 10.0 90% or greater
14 / 0.3 – 1.0 75% – 84%, 1.0 – 3.0 90% or greater

How does a furnace filter help improve indoor air quality?
A furnace filter will help remove pollutants, VOC’s, pollen, dust and other particles from the air in your home. Over time dirt and pollutants start to build up and block the filters ability to clean the air, this is the reason it is important to regularly replace your furnace filter.
