ALVI is the world’s SMARTest air filter that is able to provide HEPA class air quality, remove 98% of allergens & asthma triggers, & provide actionable insights on IAQ & filter performance. ALVI uses polarization to remove the really, really tiny particles (98% of 0.007 micron particles) without using really dense filter media, to provide better air quality and better air circulation throughout the home/facility, so your home heats up and cools down quicker. This reduces the time your furnace spends running and in turn, your furnace consumes less energy. ALVI filter cartridges have a longer life-span than the average filter, and last between four to six months. And when the cartridge has turned from fresh to foul, the ALVI app will tell you when it needs to be changed. Replacement cartridges are mailed straight to your door. The ALVI home system can fit in any furnace and air return/intake with a 1” slot. It is available in over 50 standard sizes.
