India is plagued by air pollution right now. Indians woke up to Sunday morning with pictures of the capital city plastered in smog with a near zero visibility. And while the situation in Delhi is drastic, the rest of the country isn’t any better off. Unfortunately, we only consider what we can see or what is visible as pollution (e.g., smoke) and nothing else. But did you know that there is something else that leads to air pollution too? That is Pollen. Air pollution is basically caused by 2 things – particulate matter and pollen. Around winter time, as the humidity decreases, the pollen and dust tend to be a lot more in the weather adding to air pollution.
In order to escape this air pollution, the one solution we are jumping on is the use of Air Purifiers. There’s a lot of talk about Air Purifiers and the need to install one. But there are many types of purifiers from small, portable ones to mammoth ones in the market. What is the difference between them? Which one do you choose? And how do you know what is best for you? Well, first things first, you need to be able to choose the right Air Purifier for your home. Every home needs a different purifier. Also, if you’re someone who uses an air-conditioner or heater, the rules for you are different.
The most important thing while choosing your air purifier is the size of your room. You cannot use the same purifier throughout the home, especially if it is a large home. You need a separate one for every room. And the bigger the room, the bigger should be the purifier’s capacity. If you use a central cooling or heating system, you can invest in just a filtration module which will be fitted on the device and function simultaneously with the device. They clean the entire space in one go. However, on the downside, they are expensive. You can choose one with a larger capacity than the size of your room so even if you keep it on the lowest setting, it is still effective.
The key part of an air purifier is the filter. It is what takes in the air, cleanses it and then circulates it in the room. There are different types of filters Air Purifiers come with. The first one is the High Efficiency Particulate Air (HEPA) filter, which is useful for every type of filtration: pollen as well as particulate. However, the HEPA filter does not remove chemical fumes, cigarette smoke or odors and small viruses. Also, the viruses caught inside can breed and lead to problems inside the filter. The second type of filter is Activated Carbon Filter. Activated Carbon filters are the most absorbent but then they do not remove or absorb dust and allergens and are ineffective against micro-organisms. The third type is an Ionic filter. An ionic filter works slightly differently as compared to the HEPA and the carbon filter. The Ionic filter traps the durst and pollution particles together so they stick to one another and become heavy. These heavy particles then land up on the floor. While it does clean the air, in the long run, the floor around the filter isn’t cleaned, there can be dirt accumulation and the problem can aggravate as the particles are not being actually cleaned. The last type of air filter is the Ultraviolet Pure Air Purifier. Now the UVPA purifier comes with UV radiation to destroy bacteria. While it is effective against the smallest of particles, it does not help dealing with dust and chemical gases or smoke making it slightly redundant for more polluted cities.
Now that you’re aware of the different types of purifiers and their purpose, let’s take a look at the best purifiers in the market presently:
