Air Purifier Buying Guide For Everyone

This is all the information one needs to buy an air purifier. Read on:

What is an air purifier and why is it important?

An air purifier is an essential component that keeps the pollutants in the air away, leaving the surroundings healthy.

By absorbing excess carbon dioxide and other toxic particles, the purifier ensures that the air you breathe is toxin-free. What makes it pivotal to our lives today is that it saves us from the multiple health risks that the environment poses to us.

Asthma, lung problems, irritation in the throat, eyes, and nose, health problems are aggravated in such conditions making it imperative for one and all to own an air purifier.

The least you can do for yourself is to keep your home and its air clean; we are not saying you have to but you must. 

Like a thermometer, measured in degrees, the air quality index (AQI) defines how healthy or hazardous is a country’s air for its residents.

While 0-50 degrees is healthy and AQI of 50-100 is moderate, anything above 100-150 is unhealthy and over 150 is extremely harmful.

The past few days saw the AQI of the National Capital reach above 500 and caused a state of panic. People wearing masks is common spotting now and there is no better way to protect oneself, especially when they have to step out of their houses for work.

However, when at home, people have started resorting to better ways to keep the air around them clean.

To combat the magnitude of air pollution, Delhi- NCR residents have turned to air purifiers and some of the best air purifiers in India have seen exponential growth in their sales in the past few weeks, compared to any other time in 2018-19.

Types of air purifiers in Delhi

A sea of choices is available for you, as soon as you go online or reach the market to shop for air purifiers.

All big electronic players in the market have released this product, one after another, striving to become one of the ‘best air purifiers in India’.

But which one to choose? What makes one air purifier better than the other? Don’t you fret, we have it all covered!

From this multitude of choices, how to select the best one will be easier for you to decipher once you’ve read what we have to tell you.

There are multiple features that a purifier encompasses- HEPA filtration, air quality monitoring, air exchange rate, et al. Air purifiers can be further bifurcated into different types, based on the ones available in India. Here are the most commonly found 5:

1. Ionic Air Purifiers

A commonly found and one of the best air purifier types in Delhi, ion-based purifiers create charged particles that attract airborne dust and other particles.

The weight of the impurities goes up as the ions cling with them, making them fall on the ground, thus, cleaning the air.

This modern-day technique to clean air needs thorough vacuum cleaning once the purifier has been used to clear the leftover particles that have fallen on the floor. This is a rather effective way to clean the indoor air in your house or room. 

2. Carbon-filter Purifiers

A huge, granular filter, black in colour, carbon filtration has been a successful process of cleaning the air.

The best air purifiers in India, well most of them, adopt this technique in their products and produce wonderous results.

Air purifiers with carbon activated filters can also absorb odours and other gases, neutralizing the environment and leaving your home fragrant and clean.

Lint, dust, VOCs, pet hair, household chemicals, et al, all are taken care of using carbon filters in purifiers.

3. Ozone Air Purifiers

A feature of paramount importance, the ozone protects the Earth’s atmosphere and us from the UV rays that could cause great harm.

When used in air purifiers, the ozone oxidizes everything it comes in contact with, thus killing it off. Once produced from the purifier, it kills odours and mold, leaving the air clean and healthy to breathe.

However, we have a problem! Inhaling ozone is not good for health and over the years, a number of health concerns have been raised because of it.

4. HEPA Air Purifier

Adopting one of the most popular trends from the modern world, the best purifiers in Delhi, and also the most-bought ones, use the HEPA purifying technique to filter out the air.

High-Efficiency Particulate Arresting, also known as HEPA captures the tiniest of particles into their filter, which is separated by three different components.

Inertial impaction, diffusion, interception, and sieving- the four-step process ensures that all impurities in the air are consumed by your purifier.

5. UV Air Purifier

A very reliable form of cleaning the air, the UV air purifier kills off bacteria, viruses, mold, yeast, among other organisms that tend to cause health issues among people.

This kind of air purifier uses UV light to remove pathogens from the environment. But the challenge with this kind of purifier is that it does not tackle the issues caused by dust, allergens or other solids.

UV purifiers also have no contribution towards cleaning cigarette smoke and chemical fumes. This kind of purifier should ideally be used in conjugation with some other high-quality purifier, like HEPA, for a holistic air cleaning experience.

Thanks to the extensive technology available in the market now, keeping your indoor purified has been simplified.

This invention saves time, keeps health issues at bay and offers the cleanest form of one of the most essential life necessities, oxygen.

The bifurcation of these air purifiers will be based on the kind of features offered by each air purifier, its power to absorb pollutants and price, among other things.

However, before we begin, here are the most important parameters to bear in mind before choosing an air purifier

1. HEPA Filtration Techniques 

The most effective type of filtration, for anyone, while choosing a purifier, this should be the first factor.

The most commonly found impurities come in sizes PM 2.5 and PM 10, which means that the diameter of the particle is less than 2.5 micrometers and 10 micrometers respectively.

This is impossible to catch for the naked eye but HEPA filters have that power. It can actually catch particles to size 0.1 microns, sometimes even smaller.

2. Clean Air Delivery Rate 

The CADR, also known as the clean air delivery rate is simply put, a measure of how quickly the air purifier works.

Measured in cubic meters per hour, the higher the CADR of an air purifier, the better. This element should be paired along with the air-exchange rate, which defines how much air can pass through a purifier in 60 seconds.

The air purifier with a higher exchange rate will clean more air in lesser time.

3. Smart Alerts

An air purifier filter needs to be changed from time to time, keeping a track of which is quite impossible with our busy lives.

Therefore, we all need smart machines that can tell us in advance about the need to change a filter, and thank our stars, with the advancement in technology, it is now possible.

So when buying an air purifier, make sure it offers you filter change alerts. The best air purifiers in India do, take our word for it!

4. Air Purifier Capacity

Depending upon the size of your room and the area covered, one can choose their air purifier based on the capacity.

The more affordable options cover a relatively lesser area while the costlier ones can take care of bigger rooms.

5. Lower Ozone Emission

While it is extremely effective in neutralizing the allergens and other chemical gases, ozone is harmful to the environment, breathing high-levels of which is dangerous for everyone.

So when planning to buy an air purifier, choose an option that emits lower ozone.

6. Air Quality Monitor

If an air purifier has an air quality monitor control, it is easier for it to regulate the speed of the purifier and the time for which it needs to run.

With the smart technologies now available around the world, a lot of advancement has been made in this technological sphere, making air purifiers automatic and rather smart.

So they know when to increase or decrease the fan speed or stabilize when needed. These elements should be seriously considered when planning to buy an air purifier. 

With many options available in the market, one should make wise choices when it comes to buying air purifiers in India. One should select the purifier based on their house or room size and need.
