Air pollution in India is intensifying in recent days. The current situation in the city of Delhi is an example of this. There are other health problems caused by inhaling the polluted air. Hence itself use of air-purifying equipment is inevitable in every home. The air purification equipment market is one of the growing home appliances markets and it is a very cumbersome task to select the best air purifier in India.
What is an Air Purifier?
In the broader sense air purifier (it can be also called air cleaner) is a device that can remove contaminants or impurities in the indoor air. Here we are discussing domestic air purifiers.
There are different types of industrial air purifiers that are also available to accomplish the air processing required in different industries for various applications.
We hope that this is worthwhile to discuss air-purifying techniques, as the Air Quality Index (AQI) of Indian cities is worsening day-by-day, which necessitates the need for an air purifier.
Do air purifiers work in India or Do we need an air purifier?
As per the data provided by the Central Pollution Control Board (CPCB), air contamination in most Indian cities is drastically increased in recent days, especially in the national capital region. Real-time Air Quality Index (AQI) in major cities is continuously monitored by CPCB.
Also, it is not good to hear that the cities with most air pollution are from India with Delhi in the top position.
So the requirement of an air purifier is essential during these days which can purify indoor air up to a certain extent.
Indoor air pollution is around 10 times worser than outdoor air pollution. Because indoor air pollution occurs in a smaller area.
Hence itself use of an air purifier is very useful for you in different ways.
- An air purifier can eliminate dust particles and contaminants in your room.
- Also, it eliminates about 99% of airborne bacteria.
- It can neutralize smoke inside the room.
- It avoids the expansion of allergens initiated by pets.
- As it avoids dust in breathing air, you can breathe clean air and keeps your lungs healthy.
How does an air purifier work?
As discussed above an air purifier purifies the air in its working area.
Mainly there are two types of air purifying technologies are available now. One is active purification and the other is passive purification.
In active purification as the name indicates air impurities are removed by a direct method. Active air purifiers release negatively charged ions which allow the air pollutants to stick on its surface.
In passive purification, polluted air is filtered by proper filters. Passive purification is very efficient as it can permanently remove all dust particles or contaminants in the processing air.
The air purifier uses an internal fan system to pull air through a series of filters to expel dangerous airborne particles such as dirt, pollen, and bacteria into your home. The air purifier then returns the cleaned air to the room. This process repeats itself several times an hour to maintain a healthy environment.
The air purifier pre-filter eliminates pollutants up to the size of PM10. The HEPA filter also eliminates PM2.5 particles and much smaller particles to about 0.3 microns, almost seven times smaller than PM2.5. Besides, an activated carbon filter is useful for picking up gasses and removing odors.
How do we choose a good Airpurifier?
To select the best air purifier following things are to be considered,
1. Area to be filtered (Room size)
The first and most important thing to remember is the size of the room. Room size is a key factor to select the best air purifier. There are a lot of air purifiers on the market, from compact to heavy ones. You should always go for a model designed for a slightly larger space to purify the air than the actual size of the room. For optimum performance, buy an air purifier that is designed to operate in a space that is 20-40% larger than your space. It won’t have to run the fan as quickly, so in that case, it will be quieter and consume less energy.
2. Type of Filtration
Before you get one purifier, make sure you research the type of filter used in an air purifier. To filter items like pollen, dirt, smoke, odor, and other harmful contaminants, the filter must be fitted. Also, ensure that at the primary filtration stage, the air purifier has a pre-filter that can remove pet hair and other large particles from the air.
Four filter types are available-HEPA (High-Efficiency Particulate Air), charged paper, antibacterial and germicidal precipitator, and electrostatic precipitator.
You should also regularly change the filters to increase the life span of the purifier.

To be successful, a multi-stage air filtration system is required for air purifiers. In general, a multi-stage air filtration system has three filter types.
The pre-filter serves as the first defense line and eliminates contaminants from PM10 such as dirt, smoke, fur, pet dander, broad pollen, etc. The pre-filter also helps to improve the secondary filter’s life by not allowing it to die sooner.
B. HEPA Filter
The High-Efficiency Particulate Air Filter collects PM2.5 contaminants that the Pre-Filter is too small to avoid. It can remove particles up to the size of 0.3 microns. For air filtration devices, HEPA filters are considered the industry standard. These filters are capable of removing up to 99.97 percent of air pollutants.
C. Carbon Filter
The carbon filter is used to remove volatile organic compounds (VOCs), gaseous substances, and air odors. When purchasing an air purifier, choose one with an activated carbon base. This layer absorbs all harmful airborne gases and chemicals. A larger activated carbon filter can absorb more airborne chemicals and work longer as well.
3. CADR(Clean Air Delivery Rate)
It is an important metric for the efficiency of the air purifier and calculates the purifier’s velocity of filtered air. Go for a higher CADR purifier because it means higher filtration power.
As mentioned CADR is Clean Air Delivery Rate. This allows you to identify how fast the air purifier works. It calculates how many cubic feet of air in one minute the purifier can filter. The CADR number is higher, the air filtration is greater. There are three CADR numbers of air purifiers for dust, pollen, and smoke. Consider going for an air purifier with a higher CADR rating if you have a larger operating space.
4. ACH(Air Change Per Hour)
The rate of air change indicates how many times during an hour the air purifier has cleaned the air of the entire room. This refers to the number of times the air purifier cleans the entire room’s air in one hour. So if you find an air purifier that promises 6 ACH score, it means that it will clean the air 6 times in an hour. If you or any member of your family have asthma, go for a 5-6 ACH air purifier.
5. Air Purifiers to be avoided
When you get an air purifier, there are certain devices that you should stop. For example, never go for purifiers based on UV filtration and ionization. These emit ozone can cause breathing problems. Ozone is toxic to the lungs and is likely to result in more asthma attacks and other breathing problems.
6.Portability and weight
If you are looking for an air purifier, consideration should be given to the portability and weight factor. Even a small air purifier may be able to clean a large room. On the other hand, a large purifier is going to be more expensive and take up a lot of space.
Last but not least, consider the levels of noise emissions. Together with fans, all air purifiers produce noise. So go for those who make less noise, so you don’t want the buzzing fans to disturb your sleep.
8.Customer Service and Provision for filter replacement
The filter replacement and customer care considerations must also be kept in mind when buying an air purifier. In air purifiers, filters need to be changed regularly. So, they should be ready to get one. Second, the manufacturer must have a robust network of services. This means checking the company’s post-sale operation.
Like any other electronic device you purchase from the market, air purifier comes with a guarantee as well. So check all of the warranty terms and conditions offered.
Normally air purification equipment is very expensive. But nowadays you can grab a decent air purifier equipment at the price of an average smartphone.
