Smog is increasing in the region but here are some of the best air purifiers to fight smog. Smog – the thick layer of fog mixed with smoke and other air pollutants has led to numerous accidents in the northern region and has also resulted in several health issues in the affected areas. Most of the residents in the affected areas are searching for ways to fight the harsh conditions. Besides wearing air filtering masks people are fast buying air purifiers for homes as well as other such areas to breathe in healthy and pollution free air.
Here are some of the best purifiers in the market to fight smog
HEPA filters
The High Efficiency Particulate Air (HEPA) is a system of high standard air purification. As per the report, the HEPA purifier is believed to remove about 99.97 per cent of particles that are .3 microns or larger.
The report mentions that particles that are between .3 micron to .9 micron are mid-range particles. These particles pose high levels of health concerns. The major reason for this being a major health issue is that these particles are small enough to get past our body’s breathing passages but on the contrary, these are too large to be exhaled easily. The HEPA filters retrieve most of the harmful particle found in the air. The HEPA filters are known to consume high energy.
Air Ionizing purifiers
Ionic purifiers are also effective in offering clean air. These purifiers ionize the air particles to clean the air. The ionic purifiers have purifying plates that have a charge. This charge in the purifying plates is opposite to the charge of the air particles. As a chemical reaction, these Ionic purifiers help out in removing very fine particles from the air. One of the backdrops of these purifiers is that these purifiers are sometimes known to re-circulate the impure air particles in the air that they draw into them.
Carbon purifiers
Carbon purifiers use activated carbon as an absorbent that efficiently takes in most of the impurities. Carbon filters in the carbon purifiers have small pores that chemically react to particles passing through them. These carbon purifiers are known to be efficient in capturing particles such as smoke, gas and bad odour. These is carbon purifiers do not work for purification of types of micro-organisms and allergens.
UV (Ultra Violet) purifiers
UV (Ultra Violet) purifiers, also known as ultraviolet light air purifiers, use ultraviolet light to disinfect particles that pass through them. It disinfects particles such as viruses, germs and bacteria. The UV (Ultra Violet) purifiers ensure that the virus, germ or bacteria that pass through it do not multiple or grow. The US purifiers are not effective in purifying smoke or allergens.
Ozone purifiers
Ozone purifiers oxidise the chemical substance in the air. The ozone purifiers primarily take in the present oxygen and give it a strong electrical charge. This electric charge allows the oxygen (O2) molecules to rearrange themselves to further form ozone. It has been reported that Ozone purifiers are supposed to be the fastest air purifiers but ozone itself is considered harmful for the human body.
