Air purifiers are products that are produced and marketed in different sizes. From personal models for personal use and in-car air purifiers to large appliances for home and industrial use, all are produced under the name of air purifiers. These devices, as their name implies, can only purify the air in a closed space such as a room to clean the ambient air of allergens, some germs, dust, carpet lint, sofa and animal hair. Air purifiers vary in efficiency and effectiveness, ranging from 30 to 99.99%.

Activated carbon: (ACTIVE) This filter has the ability to absorb unpleasant odors and more than 3000 types of harmful gaseous compounds and plays an important role in absorbing chemical agents.

HEPA filter: (HEPA) is capable of absorbing a variety of bacteria, viruses and airborne dust particles up to 0.3 microns in diameter and purifies almost all airborne particles that are breathed. HEPA filter is one of the strongest and most effective filters in the air device and removes more than 99.97% of airborne pollutants. (Similar to car engine air filter)

Lamp: (UV) in the air purifier, with ultraviolet radiation with high antiseptic properties, kills microorganisms in the air such as bacteria, viruses and fungi. UV lamps, by irradiating at a certain frequency, break the RNA of the corona virus and in other cases the DNA of viruses and bacteria, and eventually cause their destruction.
