Filtr Revolution is designed to provide a maximum flow of cleanroom grade air, while minimizing the sound levels inherent with high-speed air purification blowers. Filtr is focused on reducing the health risks associated with indoor air pollutants (such as asthma, allergies, COPD and heart disease) by detecting and removing airborne and surface contaminants such as viruses, bacteria, smoke and many other forms of pollutants. Filtr has also developed the Hope 220, a world-class disposable N95 respirator that has been designed to provide a secure fit with the highest level of comfort, breathability, and durability.
