3 July 2017
Have you ever found yourself sneezing for no apparent reason, or a running nose or sudden itching? Well it can be all due to pollen, animal dander, mold spores or dust in the air.
Around 46% people in the world are unknown to their own allergies and only comes to know when something grave happens.
With the increase in pollution and dust in our environment air born allergies are also increasing rapidly; and in response to this air purifiers have evolved.
Air purifier removes the antigens and allergens from our home and reduces the risk of allergies and asthma to a great extent.
Benefits of Air Purifier
In todays world where the greatest danger on earth is pollution, the quality of the air we breathe is deteriorating; leading to many respiratory diseases, with asthma leading the chart. Thus, the use of Air Purifier is an absolute necessity.
# Air Purifier suck up second hand smoke.
# They also eliminate any kind of odour. They are great at removing medicinal odour, heavy cooking smell and even cigarette smoke.
# Air Purifiers are a boon for people with health issues as it cleanses the tiniest particle in the air.
# They are a helping hand in maintaining the room decor. Air Purifier reduces the need of housekeeping and maintenance.
# Overheating of electric equipments and fire hazard are also regulated by air purifier.
Air purifier may seem like a new innovation but they have been present for almost 200 years now. What started as a protective mask has not evolved into complex machines to eliminate air pollutants.
The basic Air purifier uses fine sieves or sifters that circulates air through them and filtering it in the process. Finer the sieve better the filtering. And the more the air passes through them the purer it becomes.
Ionizing Purifier uses corona discharge method to create ions (charged molecules). They give the molecules passing an additional electron, giving the molecules a negative charge; once the particle is charged it attracts to anything with an opposite charge, there are plates present to attract these particles. All the particles clump together and get heavier and settle out of the air.
These are the two most popular type of Air Purifier sold in the market currently. Apart from these there are other purifier as well such as ozone generators and UV light cleansers.
What is HEPA
HEPA- High Efficiency Particulate Air. It is the most common and most reliable air filter. The standard for HEPA are set by States Department of Energy (DOE). Filters that have to meet the HEPA standards should have many applications such as-
# Use in Medical Facilities
To be qualified under HEPA, an air filter must remove 99.97% of all particles under 0.3 microns. HEPA has become a generic term for highly efficient filters.
HEPA filters work by mechanical means unlike many other air filters present in the market, which reduces the chance of airborne allergies to a bare minimum.
HEPA filters working is a 3-step procedure-
# Interception: Small granules are captured and separated # Impaction: Larger granules are captured # Diffusion: Both the small and large granules are prohibited from entering the atmosphere again.
They are designed to collar very fine particles efficiently, but it does not help in filtering out gases or odour. For this purpose, an activated carbon (charcoal) is used separately in addition to HEPA filters.
The only drawback to HEPA filters is that it demands maintenance and regular change of filters. But that is a very small price to pay for your health.
Before buying an air filter it is very important to recognise your needs first. There are n number of air filters in the market, to choose from which can get a bit overwhelming, so here is a checklist of things that your air purifier must have-
Go for a HEPA filter only, there'll be many filters claiming to be HEPA like but they won't be as efficient as HEPA.
Your purifier should have charcoal as it beats the bad odour and keep harmful gases at bay.
Check the Clean Air Delivery Rate (CADR). Higher the CADR, the better the air purifier is. It is the purifiers ability to remove pollutants from a specific amount of air.
Determine the square feet area of the place you'll keep the purifier at. Buy accordingly, manufacturers mention the area in square feet that the air purifier will work best in.
Avoid purifiers with UV lights and negative ions, they will cause more harm than good. Purifiers with these technologies have proven to increase asthma problems among users.
Go for purifiers with built in pre-filters. They are great assist to HEPA filters and increase the life of air purifiers.
With the rapid increase in uncontrollable pollution air purifiers will become every household's necessity. Let's try to stay ahead of our times.
