• Indoor Air Quality Management

Founded by the team of IIT Madras graduates we at AirOK believe in clean air is a necessity for every individual. As our progress in day to day life we have been unaware of how polluted our surroundings have been. Bringing together all our expertise we have designed and developed a novel patented air filter that can remove all the air pollutants in an indoor and ambient environment. The designed filter is affordable, long-lasting, and costs three folds less than existing commercial air filters available in the market thereby resulting in lower maintenance costs. AirOK air purifiers are smart and User friendly. It comes with many other features that you would love. We have been helping most of our clients with a customized Air filtration solution as per their requirements. 

How Bacteria and Viruses are killed using EGAPA

• EGAPA Air filters are typically modified activated carbon with chemical impregnation to enhance filtration efficiency.
• In Impregnation processes, we used to modify the surface structure and chemical properties of Activated carbon using different chemicals. Chemisorption is a type of adsorption that involves a chemical reaction between the surface and the adsorbate. New chemical bonds are generated at the adsorbent surface. Chemisorption occurs when molecules of a volatile pollutant chemically react with the adsorbent’s surface to form non-volatile products.
• This adsorption method was applied to reduce airborne microorganisms and many other toxic gases.
•  The GAC (Granular Activated Carbon) itself had a maximum adsorption capacity of 2217 CFU/g for airborne bacteria and 225 CFU/g for fungi.
• Most of these particle sizes of 0.65-4.7 micron. Those airborne microorganisms with small particle size was apt to be adsorbed by allowing the Air on to the filters by using blowers.
• Relationships between GAC surface characteristics and its adsorption performance demonstrated that porous structure, large surface area, and hydrophobicity rendered
• GAC an effective absorber of airborne microorganisms.
