Our VitaShield IPS technology harnesses the power of natural air purification to trap indoor air contaminants — without generating ozone or secondary pollutants in the process. Air passes through high-grade multi-layer filters, including active carbon to reduce gases and odours and a HEPA filter capturing 99.97% of airborne particles, as small as 0.3 microns. That includes pollen, dust, dust mites, pet dander and mould spores.
