Sources of Indoor Air Pollution
Before selecting the best air purifier in India you need to know what are the pollutants that are polluting your indoor space and where are they coming from.
It is common knowledge that our cities and towns are highly polluted. Needless to say that the outdoor air quality does affect indoor air quality.
Particulate matters that pollute outdoor air also pollute the indoor air through the doors and windows.
However, this is not the only source of indoor air pollution.
We are habituated to using a number of artificial fragrances, insect repellent liquids, deodorants, asbestos, pressed wood products, wall paints, radon, automotive products including stored fuel, cleansers, disinfectants and more.
All these pollute the indoor air with volatile organic compounds, inorganic material like lead and mercury, dust and more. Apart from these there are spores from mold and dust mites all of which are harmful for your health.
Particulate Matter And Role of Air Purifier
The sheer variety of air purifiers is borne out of the variety of particulate matters found in the air. Indoor air is contaminated with a variety of particulate matter ranging in size from PM 2.5 to PM 10.
There are other particles found in the air too and these are even finer than PM 2.5. Some of these are even finer than 0.1 µm and are known as ultrafine particles.
This is why you need to find an air purifier that can purify the air off all the harmful particulate matters. So, if you are living in a city like Delhi, you need to look for the best air purifier for Delhi.
Types of Particulate Matters In Indoor Air
PM2.5 are those particles which have a diameter of less than 2.5 µm. Such a dimension can be roughly considered to be about 3% of a human hair.
These are not visible to naked eye, but are present in the air. Such particles mostly result from combustion of diesel and petrol and contribute to outdoor air pollution.
However, outdoor air pollution is not restricted to outdoors. It does get into indoors through doors and windows.
Moreover, PM2.5 emission from indoor pollutants such as chemicals from cleaning products and carpentry, bacteria etc. too contribute to indoor air pollution. They can be harmful to lungs as well as other organs of your body as you continue to inhale them daily.
PM10 particles have a diameter 10 µm or less. Comparatively, they are larger sized particles, but they too are harmful for your health.
Dust, pollen, mold etc mostly contribute to PM10 pollution in indoor air.
The Best Air Purifier in India – Selection Criterion
Before selecting the best air purifier in India you have to consider the following factors:
To ensure maximum purification throughout your living space you need to select the best air purifier that has a coverage area greater than the total living space.
So, it is the area of your house that you need to figure out first while looking for an air purifier. If you are looking for a purifier for your study room or bedroom, the basic ones may serve the purpose.
However, if you are looking for a device to purify air in larger rooms you need to get a large purifier or buy two small purifiers. You can get the details of coverage area on the purifier label.
This will help you to select the best air purifier in India among the most suitable ones for your room size.
Clean Air Delivery Rate (CADR)
Clean Air Delivery Rate is the international standard for calculating effectiveness of an air purifier. It measures the volume of clean air delivered by the purifier in one minute.
It helps to identify how fast a purifier can clean the air in a room.
The higher the CADR number of an air purifier, the faster it is able to clean the air in the room.
Theoretically, CADR indicates the ability of the air filter to reduce dust, smoke, and pollen particles ranging from 0.10 to 11 micron.
It is easy to gauge the size of a micron by comparing it with the size of a strand of human hair which measures about 100 microns in diameter.
The standard of CADR is ANSI/AHAM AC-1-2006, but it is solely meant for measuring the efficacy of portable air purifiers. Whole house air purifiers are not covered by this particular standard.
Before buying the best air purifier in India you have to consider the filtration system of it. Filtration system is the main component of an air purifier.
Some of the best air purifiers have a 3-layer filtration system. It consists of a HEPA filter, a pre-filter, and activated carbon filter.
All these filters work together to remove dust particles, pollutants as well as odour. However, these filters work independently of one another.
HEPA: High-Efficiency Particulate Air/Adsorbing/Arrestance
High-efficiency particulate air (HEPA), also known as high-efficiency particulate absorbing and high-efficiency particulate arrestance, is an efficiency standard of air filter.
The job of HEPA filter is to trap dirt and dust. It makes use of three principles, namely – inertial impaction, interception and diffusion to serve the purpose. The HEPA filter can remove 99.97% of PM2.5 impurities.
That is an astounding performance by any standards. Therefore, having a HEPA filter is mandatory for the unit to work successfully.
Pre-filters are quite common and they are also present in air conditioners. This is the first line of defense against impurities. These are usually made of non-woven polyester material or foam.
These filters can trap animal hair, human hair, large dust particles etc.
Activated Carbon Filters
The job of Activated Carbon Filter is to eliminate Volatile Organic Compounds (VOCs) and bad odour. VOCs are present in deodorant sprays, apparel perfumes, wall paints etc.
These compounds interact with dust particles in air and create smog, which may trigger asthma and also scar your lungs.
So, the activated carbon filter plays a significant role in eliminating the most harmful of particulate matter. It also removes odours and obnoxious gases by adsorbing them.
However, you need to remove this filter once it becomes full of impurities.
While some purifiers combine all three functions into one unit, others come with three separate filters. In most cases
it is convenient to select one with separate filters since you can replace them individually in case one or two of these need replacement.
Ion and Ozone Generators
These generators make ions and discharge them into the air. These particles will stick to the pollution and cause them to fall to the earth as a result of their weight.
The disadvantage is that breathing in ozone isn’t good for your health. Furthermore, an overabundance of ozone in nature is also harmful.
This is a basic necessity for air purifiers. In most cases there is either an LED indicator or a digital display to indicate air quality. Those with digital displays indicate the actual air quality inside the room.
In these devices it is easy to figure out if you need to keep the device running or you can turn it off.
Most air purifiers do not have a remote control. This means every time you need to enable or disable a function or change the mode, you have to get up and do it manually.
This is why the best air purifier in India 2021 comes with a remote control. Some modern air purifiers can also be controlled by apps through WiFi connection.
This is certainly a helpful feature.
Filter Replacement Indicator
Filtration system is the core of an air purifier. However, the filters have a lifecycle and they need to be replaced from time to time.
Mostly filters run out of life in few months since it is they who bear the brunt of all the impurities.
So, you need to replace them with new filters. But how do you know when to replace a filter? This is why the best air purifier in India comes with filter replacement indicator.
In some devices the filter replacement indicator turns orange to indicate that it is time to replace a certain filter.
Smell sensor is a useful component of modern air purifiers. It often happens that people get habituated to a certain odour and they no longer sense it.
However, the smell sensor can sense all kinds of odour and smell and remove the particulate matter responsible for it. So, a smell sensor can be a good piece of utility for the best air purifier in India.
Noise Cancellation System
There are some air purifiers which cause too much sound while working. The sound mostly emanates from the fan and it increases as you make the device work with higher efficiency.
However, having a buzzing equipment in the bedroom at night or in the study room is an irritation. This is why modern air purifiers are equipped with noise cancellation or sound proofing systems.
These systems make sure that the noise does not come out of the device and disturb people.
Brand and After Sale Service
Electronic products may develop problems even if you a buy an expensive device. This is why after sale service and customer support are the essential parts of every electronic product.
So while buying the best air purifier in India you need to inquire about after sale service and customer support of the brand.
Warranty is an essential part of every product sold from a store, whether you buy online or offline. While buying the best air purifier in India you must see that the manufacturer offers warranty for at least two year or more.
Some of the best air purifier brands also offer extended warranty. You can opt for that as well.
Although today air purifiers are no more a luxury item but they don’t come cheap also. The price also depends from model to model.
But we recommend that you choose it wisely as you cannot change an air purifier every year. You should also consider the cost of replacing filters annually.
Hey there, you can have the purest air by going organic. Remember, every electric item you use, you leave carbon footprint on this planet.
Instead, get a green thumb by choosing natural Plants and get more benefits without wasting money on something mechanical.
