HEPA filters with maximum filtration and absolute efficiency. Capable of retaining particles in suspension of a size of less than one micron: tobacco smoke, viruses, bacteria, germs and aerosols, among others. The filter has a metal protection grid on both sides to prevent damage.
Available in two models depending on the gasket, which can be polyurethane or liquid gel-silicone. Also available in different dimensions depending on the air flow requirements of the installation. Compatible with Dif-vent and Dif-pur filters units, for spaces where air quality cannot be compromised.
