We can all agree without a doubt on the fact that air pollution and contamination levels are high today than it was, years ago. The most common and evident causes of air contamination are attributed to vehicular contamination, dust, tobacco smoke, factory, smog, mould, bacteria, virus, and pets.
These factors cause allergy and asthma in most people. Air Purifiers are made with a view to help protect allergy and asthma prone individuals from these air pollutants.
They are designed to filter out contaminants from a home or office thus providing a clean and pollutant free environment to live and work in.
There are various methods used in the Air Purification process like Thermodynamic Sterilization, Ultraviolet Germicidal Irradiation etc.
Most Air Purifiers either contain an adsorbent material that filters out chemicals, fumes, and odours out of the surrounding air.
Some have Ozone Generators that work by disinfecting or deodorising the air. Another mechanism incorporated into Air Purifiers is projection of Ultraviolet Radiation that sterilises micro-organisms like bacteria and viruses from the atmosphere.
The Good and the Bad:
The biggest question among people who want to purchase or are already using an Air Purifier is whether it actually works and whether it’s worth investing in one.
The Air Purifier Industry is built on heavy marketing and high cost. The device itself incurs high electricity, installation and maintenance costs because of which people are highly sceptical about whether it’s worth their effort and money.
Another thing that is discouraging a lot of people is the negative health impacts that supposedly arise from using an Air Purifier.
Big Air Purifiers work by ionising Oxygen in the atmosphere and converting it into Ozone. This chemical reaction is said to be detrimental to health, particularly to the respiratory system.
This seems ironic because the product is marketed towards chronic allergy and asthma patients. The fact that the FDA has warned against the usage of air purifiers around children does not help the case.
- The biggest and most expensive Air Purifiers do have a very high success rate in filtering out air contaminants greater than 0.3 microns like Asbestos, Pet Danger, Pollen, Cigarette Smoke, and Dust. This has proven to be most beneficial to people who are allergic to these contaminants.
- Small Air Purifiers do not demand high electricity and maintenance costs. Console sized air purifiers and table top air purifiers showed exceptional results in eliminating pollen, plant spores and cigarette smoke effectively. They simply need to be plugged into an outlet.
- Large household (HEPA) Air Purifiers can be installed only in a ventilation system.
- Installation and monthly electricity costs are extremely high.
- They need a lot of horse power to operate.
- The ionisation of Oxygen into Ozone is harmful on prolonged use.
The dangers of having an air purifier do outweigh its benefits. But it won’t be fair to say that they are completely harmful. The best way to go about it if you are a chronic allergy or asthma patient or if you want your home to be free from dust and other pollutants is to invest in an air purifier only from a top brand.
But be prepared to incur extra costs. It is also a wise decision to buy a small one like a table top air purifier. To protect yourself from the dangers of ionic air purifiers, refrain from using it all the time and do not use it excessively around children. Use it to your advantage and protect yourself against the dangers that technology poses.
