The Science behind Air Purification Technology

Air purifiers purify the air by trapping the airborne contaminants like dust, mold spores, dust mites, chemicals, odors, and toxins. The fresh air surround which we breathe in is not always safe for us, so air purifier plays a vital role in making the air around us safe and healthy to breath.

There are mainly four types of air purifiers depending upon the technology it uses.

1. HEPA Air Purifiers: It traps 99.97% of airborne particles up to .03 microns. Also, due to the technology used in these filters, airborne bacteria and viruses will not multiply in the filters and spread.
2. Ozone Generators: It is basically effective at trapping odors but the ozone generators release high levels of ozone which is a respiratory irritant. So, many rooms cannot be entered until 24 hours have passed.
3. Electrostatic Precipitators: By charging incoming particles with negative electrical charges, these negatively charged particles collect onto electrostatic plates. Maintenance is very high as the metal plates can become overrun with particles.
4. Ultraviolet Light Air Purifiers: By using radiation from UV lights, particles, such as bacteria, viruses and mold spores that pass through the light are killed. Unlike filters and plates, that collect particles as they pass through, the purpose of ultraviolet light is to penetrate the outer structure of a microorganism’s cell and alter its DNA, permanently preventing replication and causing cell death.
5. Activated Carbon: A highly porous form of carbon can be heated to extreme temperatures to increase the surface area. One activated carbon has the surface area of 500 sq. metre. Although it will not trap particulates, activated carbon is very effective at trapping chemicals, odors, VOCs and off-gassing.

One of the most famous air purifier is the Vollara air purifiers. Vollara products use intense technology, which combines five nature-based processes into one unique system. It is a surface purifying device having a purifying cell structured for maximizing the realized photo catalytic reaction at a photo catalytic surface without using an additional ultraviolet bulb. The purifying cell positions at least three photo such surfaces about a single ultraviolet bulb such that the surfaces substantially encompass the ultraviolet bulb and are saturated by UV light radiating from the bulb. Just because these surfaces are saturated, the potential photo catalytic reaction at the surfaces is fully realized. Stated differently, the realized reaction is maximized by the purifying cell. Because of which the purifying cell maximizes the purifying capacity of the photo catalytic surface and, thus, the purifying cell itself also gets maximized.

Thus, it is necessary to purify air because clean air is important to human and animal health to increase life expectancy. Pollutants can cause harm in various ways depending on the type of pollutant and the timescale of the exposure. Moreover, we spend 90% of our live indoor. So, purifying this air is of utmost important.
