Review on 🌀 Nordic Pure 20x25x4 Pleated Furnace Filter by Jonathan Clark

I have a complete Bryant Evolution heating and cooling system, including the GAPAA2025 Perfect air purifier. This is an electrostatic ionization unit that requires non-metallic air filter cartridges. I temporarily used Nordic Air 20x25 filters during a renovation as they are much cheaper than Bryant filters. I heard a very fast clicking sound coming from the filter section. My HVAC Tech technician showed me where the small wires on the back of the Nordic filters were grounded, causing sparks on the frame of the Bryant gear. He suggested that the small charge carried by the ionization part of Bryant's equipment was grounded by thin wires on the back of the Nordic filter. We removed the Nordic filter from the system and the clicking noise is gone. As we dimmed the lights we actually saw the earth sparkle from the Scandinavian wire on the back of the filter. These are great helpers when not using them with a Bryant Perfect air purifier. Much cheaper than Bryant's version.
