The current pandemic situation has compelled us to take a relook at our approach towards life. While those living in metro or even smaller cities were earlier grappling with hazardous pollution levels, the focus has now shifted to making homes safer, cleaner and more hygienic. Remember, clean air is not a luxury, but a basic necessity for all. Many believe that clean air is not possible due to constant degradation of nature and their opinion cannot be quashed on logic. Fact remains that even the cleanest environment can contain particles and dirt that may be detrimental to our health. And this is where air purifiers come into play.
What’s even more overwhelming is that a few companies
have developed air purifiers with technologies that make life safer, hence
better. Here we enlist four such companies who are out there to clean and
purify the air that we breathe.
1. Dyson: Dyson
offers an air purifier that automatically cleans and heats a room and claims to
capture 99.95% of harmful pollutants as small as 0.1 microns. Its trademarked
Air Multiplier technology automatically senses pollution, captures ultrafine
pollutants and projects purified and heated air. The air purifiers function on
three intelligent sensors that are powered to tackle PM 2.5, PM 10, VOCs and
NO2. The purifiers also have an in-built LCD screen to show room temperature
and the gases and particles detected. Two separate filters work simultaneously
to project over 290 litres of smooth, purified air per second.
2. Air Ok: Founded
by a team of IIT Madras graduates, Air Ok has designed and developed a
revolutionary combination of air purifiers with high efficacy and performance
with a unique design and patented filter technology called EGAPA. Unlike other
conventional air purifiers, the technology developed by Air Ok can remove
particulate matter as well as acidic, alkaline and volatile gaseous pollutants.
The filters remove up to 99.7% of harmful indoor air pollutants. The concentration
of CO2 defined the quality of air in an occupied indoor space, and the EGAPA
filters are made of special media that can absorb CO2 along with other acidic
gases. This technology has wide range of applications
especially in all mechanically ventilated indoor spaces where there is no
provision for fresh air to enter.
3. Sharp: Sharp
boasts of an original sanitizing technology named Plasmacluster Ion technology
that purifies the air by emitting positive and negative ions. The air purifiers
from the house of Sharp work on dual purification mode, and its H14 HEPA
filter, voluminous granular active carbon filter and a pre filter work
simultaneously to ensure air that’s clean and safe. They can clean and purify
air four times in one a room of approximately 200 square feet space.
4. Philips: Philips
air purifiers are powered with AeraSense cutting technology that can identify
fine particles even smaller than PM 2.5. According to the company, AeraSense
adjudges quickly even the slightest of change in indoor air condition and
automatically adjusts the air purifier to ensure clean air. The air purifiers
are further equipped with an LED colour ring to let one keep a tab on the air
condition. Philips also offers VitaShield intelligent purification system to filter
up to 99.97% of particles as small as 0.02 microns. They also have a mechanism
in place to alert an user before the purifier wears out.
