Now a day, Air purifiers are becoming essential in our homes or offices, which makes us think, why we need to purchase these Air Purifiers or are these purifiers protecting us from air pollution or are these air purifiers only for indoors and not for outdoors?
To get the answer, let’s look at some facts about Air Pollution.
As we know in metro cities like Delhi, Mumbai, etc, air pollution has increased, and the only reason for this is not vehicles like cars, buses, bikes, etc, but also industries, burning of crops, mining operations, construction, etc. All of these factors are responsible for air pollution. Also, Diwali has passed off in India, due to the burning of crackers air pollution was increased.
If we observe, in Delhi at this moment, there is smog, not fog due to which we can’t see the road properly. Smog is a type of air pollution, contains very minute particles of size PM 10 and PM 2.5 which can’t be seen with naked eyes and are present in the air in the form of dust and can be seen in the presence sunlight coming from the window. These particles can cause various allergies, asthma or other respiratory diseases.
Can Air Purifiers reduce Air Pollution?
Air purifiers can’t remove air pollution because air not only have PM 2.5 particles but also have PM 10 particles and other harmful gases released from car emission and these air purifiers can’t completely clean the air.
Purpose of Air Purifiers
The motive of Air purifiers is to improve the air quality inside your home, offices, etc. Specific air purifiers can clean the air of a specific area like a bedroom or 1 sq feet and the area should be close to the air purifier so that it can suck the air through its filter and release the clean air.
Different Air purifiers from different companies clean different types of dust particles, odour due to smoking, and the smoke released due to the burning of food, pet’s hair, etc. They are specially designed for people sensitive to allergies. But all purifiers can’t do all kinds of cleaning.
Where to purchase Air Purifiers from?
You can purchase Air Purifiers of various companies online from on websites like Amazon, Flipkart or from the market also.
Point to remember while purchasing an Air purifier for your Home or offices
Contains HEPA filter and Carbon activated filter
Air purifiers should have a HEPA filter that is high- efficiency filter helps to clean bad odour from the air. It should also have a Carbon activated filter that captures different types of gases. Together both filters help to clean the air. Some purifiers have a special type of HEPA filter that can capture fine particles, around which there is a mesh called Pre-filter that increases its lifetime.
Some American or other companies certify different Air purifiers with various certifications like AHAM, Air Mind, ECARF. So, to buy a certified air purifier is the better option, if they are in the budget.
3. Check Noise Level
Some Air purifiers when cleans the air efficiently also make noise, you should also check their noise level by running it at full speed.
4. Air Flow Ratio
Air flow ratio is also important. As air purifiers suck the air and give back pure air, therefore the ratio of air per cubic meter coming is important. The Size of the room and how much area does the air purifiers covers are also important. E.g., if the air purifiers cover the area of 600m2, then room size should be equivalent to it. So, before purchasing air purifiers measure the size of the room in m2 where you want to install it. You can get this information from the box of an air purifier or from the website where it is listed.
5. The replacement cost of Filters
Check the replacement cost of different filters present in the purifiers. This cost approximately is ₹1500-₹2000, If is high I will not recommend you. These filters can be replaced after the heavy usage of 6 to 8 months, after that you need to purchase them.
It talk about filters, you can get good purifiers between ₹15000-₹20000, which also have other filters like UV light filter that cleans the air with UV light. In short, we can say good Air Purifiers are on that have different filters to clean the air efficiently but basic air purifiers should have HEPA and Carbon Activated filter so that they can clean bad odour.
