A clean home is a safe home

Global warming and air pollution are two of the most worrisome topics that have captured the minds of experts all over the world. Air pollution is the root cause of various diseases and respiratory allergies that were unknown to mankind for a long time. But sadly due to the rapid advancement and urbanization today, we have exposed ourselves to the damaging effects of inhaling poisonous air all the time.

A greater number of deaths are reported every year caused by air pollution. And air pollution is also one of the vehement causes of autism, asthma and preterm births today. Surprisingly, most of the people feel that air pollution is only a concern when you have to step outdoors. But, on the contrary, air pollution also affects us while we are indoors. Inside our house too, there is a vast array of air pollutants like dust, molds and toxic chemicals which can cause serious allergies. These are all the more dangerous for those who are prone to respiratory problems.

So, in order to make sure that you breathe in clean air, you must consider buying HEPA filter in air purifier for home.

HEPA stands for High-Efficiency Particulate Air. In simpler words, it is a filter famed for trapping air particles quite efficiently. What individualizes HEPA from the rest is that a true HEPA will stop almost 99.97% of the particles of 0.3 microns or bigger. But this does not imply that it can’t trap microns smaller than 0.3. Filters which are designed to have a sturdier threshold can capture smaller microns as well.

Functioning of HEPA Filter

HEPA purifiers trap contaminants in a complicated web of filters. The filter does it in 3 techniques depending on the size of the air pollutants, diffusion and interception and sieving. Smaller particles of less than 0.3 microns are diffused while travelling through the filter and are trapped after a collision with the filter. By the process of interception, the medium-sized pollutants are sucked by the fibers while moving through the filter .In case of larger particles, it is captured by implementing the process of sieving or inertial impaction.

If you think that all the HEPA filters work the same way, then you are wrong. They have the same work purpose, correct, that is to purify your home but they have distinct work formulae. Different air purifier brands employ various techniques to design their HEPA Filters. For example, the brand IQAir’s HEPA filtration can trap particles as small and 0.003 microns by utilizing their nanofibers.

Some popular air purifying technologies which are in rage apart from HEPA are UV technology, ozone and activated carbon methods.

Things worth consideration

If you wondering to buy a HEPA filter in air purifier then make sure to read the specifications before buying the most suitable product for your use. Also, do make sure to check the label of the product, to see if it has got a genuine HEPA filter or a HEPA-like filter.
