- VariCel filters are designed specifically to improve Indoor Air Quality (IAQ). With efficiencies up to MERV 15, VariCel filters effectively trap and control small airborne droplets that could carry viruses and bacteria, and other airborne lung-damaging particles. MERV 14 VariCel filters are also available with antimicrobial.
