Air Purifier Buying Guide

If you have clicked on this article, there is a big chance that you have already made up your mind about buying yourself an air purifier. However, there must be many questions looming over in your mind about the safety, efficiency, maintenance, andof the product you want to buy. This buyer’s guide has been curated to help you with all these questions!

Why Do You Need an Air Purifier?

You may be surprised knowing all the different benefits an Air Purifier can bring. One of the biggest beneficiaries of this device is Asthma patients. If you are someone who suffers from Asthma, an air purifier can largely reduce your risk of triggers within indoor spaces. We all know that indoor spaces can harbor a variety of substances that can set off an attack—like the use of perfumes, deodorant, air fresheners, or certain food smells. An air purifier can prove to be a good roadblock for all Asthma triggers indoors.

Another set of people that can enjoy the advantages of an air purifier are the ones who have dust or pollen allergies, or even the ones who have housed a pet (or two). This device can help remove all types of bad smells and pet dander from the air. It is also efficient in doing away with pollen, dust, and other allergens inside your house or workspace.

Air purifiers can also reduce your risks of lung diseases by trapping the harmful smoke emitting from chemically-fueled cigarettes. While another usage of this appliance can do away with Radon gas, which is a naturally-occurring radioactive gas, and reduces the likelihood of you developing lung cancer.

Living in an urban society can bring along many types of pollutants inside your house that can be managed and eliminated easily by installing an air purifier. Overall, an air purifier has many advantages that you can enjoy, even more, if placed in a ventilated space.

Know the Air Pollution Level in Your Home

Hold on! Before you begin with searching for an air purifier, you need to first have a grasp on the air pollution level inside your home. There is a chance of higher risks of corrupted air within your homes if you reside in metro cities like Delhi, while lower risks for cities like Kochi have been known for its rather clean atmosphere.

You may also be grappling with bad indoor air health if you use incense sticks or mosquito coils often. Both of which are very near and dear to our Indian households. Therefore, you will need an air purifier to deal with these substances and clear out the air in your house efficiently.

Apart from this, several reasons require you to use an air purifier compulsorily like seasonal allergies, Asthma, renovating your house, presence of pets, and being in close proximity to industrial spaces. If you fall in any of these categories, your only way out of bad respiratory health is getting yourself an air purifier.

Features You Can Find in Air Purifiers in India 2022

There are many types of features you can find in air purifiers in India 2022 . Some of them we have listed below for your reference.


Pre-filters are exactly what they sound like as they are placed at the forefront to tackle the big mess before the inner filtration process. This feature can add many years to your air purifier’s life by capturing some of the largest particles of dust and mold in the air. Pre-filters are also extremely affordable and you can even wash them if they get too dirty!

Adjustable Fan Speeds

Another valid feature that you will come across in air purifiers is adjustable fan speeds. Most of these devices will come with a speed setting between 2 to 5. You will also find some models with options for turbo speed that will accelerate the process of purification (but they will be noisy as hell). This way you can regulate the device and its working according to your requirement.


You do not need the air purifier to stay on all the time, but there is a chance you will forget to turn it off. In these cases, an automated time helps turn the device off when the time comes and saves you a lot of electricity.

PCO & Anti-Microbial Treatment

Photocatalytic Oxidation is an extremely advanced filtration process that uses UV light to keep all the chemicals and other bacteria, fungi, and mold at bay. Another great way to prevent the spread of bacteria and viruses and an anti-microbial coating on the purifiers. These two features will not only keep you in the best of shape but will also increase the life of the filter.


Many air purifiers nowadays come with indicators for their filters. This indicator helps you replace or wash the filters whenever they have been stuffed with pollutants and grime. This feature can massively increase the productivity of the machine and help you enjoy its benefits to its full potential.

Air Quality Sensors

The air quality sensors can monitor the air by looking out for specific air pollutants and making the necessary adjustments to remove those substances almost immediately. Many air purifiers made in recent times come equipped with these sensors.

Remote Control & Mobile App

It is easier to manage machines with remote control, and with air purifiers, you will find many models that come with a remote that helps you manage the device from a distance. A mobile app can also assist you in controlling the purifier from the ease of a couch or a bed.

Types of Purifying Techniques in Air Purifiers

Air Purifiers have many kinds of purifying techniques and filters to offer you. However, how do you decide on the perfect filtration process for yourself? We have listed all of them below along with their advantages, disadvantages, and usage.

HEPA Filter (High Efficiency Particulate Air Filter)

HEPA filters are probably the most powerful and efficient filters available on the market. Their filtration is considered to be of the highest level. The ultimate aim of the HEPA filters is to catch the radioactive dust particles looming around in your apartment, and the US HEPA standard was created way back by the Atomic Energy Commission.

These filters are known to eliminate more than a whopping 99.97% of all the microscopic particles. The smallest particles bring as small as 0.3 microns. Therefore, if you have an allergy to pollen, or you have housed a pet, then you can be sure of removing all the triggering particles from your house with the help of these filters.

Beware, you will find many air purifiers that use terms to misguide you, for instance, “HEPA-like” or “HEPA-type” are words you need to scan the product for. You want to find the true HEPA that is capable of blocking and eliminating even the smallest particles. This is also one of the reasons why you will find HEPA filters to be rather expensive than other filters.

Make sure to look for larger square footage, as that means the product will be more efficient in removing particles and will have a better performance overall.

Ionizers and Ozone Generators

Ionizers and Ozone generators work almost in a similar way, although they produce molecules different than each other. They produce charged ions or ozone which helps in capturing the particles looming in the air with a neutral charge. They help the air purifiers to remove the small particles easily.

However, there is a set back to these generators that you need to know about before you jump into such a product. People who have respiratory issues can experience irritation in their lungs after being in close proximity to Ionizers or Ozone filters. If you suffer from a chronic breathing issue, you should avoid these purification techniques.

Electrostatic Filters

Electrostatic Filters have a similar working to ionizers or ozone generators. They too charge the particles present in the air and collect them in the machine. To clean these filters, you will have to remove the plates used to capture the particles and wash them before you use them again.

The one thing you need to beware of is that these filters produce ozone. Therefore, they can be a disadvantage to Asthma patients and people with chronic breathing disorders. You also need to clean these filters regularly or else they will start harming the air-flow of your house.

Activated Carbon Filters

You can use carbon filters with different types of air purification techniques. The amazing tendencies of carbon help you trap different types of odors and gases that go through it. It begins to remove them from your indoor environment which can result in sterile and pure air at your disposal.

This filter also has the potential to trap the large particles inside the carbon’s pores. Therefore, if you ever find your existing air purifier not doing a great job at tackling the stench indoors, you can fix an activated carbon filter and get the job done efficiently.

How to Choose the Best Air Purifier in India 2022 ?

There are several factors you need to pay attention to before you get your hands on an air purifier. Here we have listed some of the aspects of your purifying device that are crucial to your health and its efficiency. Make sure to tick all the boxes before you make the final purchase.

Size of Air Purifier and Room

The size of the air purifier is of the most importance. For the device to work properly and according to your requirements, you need to check the square footage rating on the packaging. After this, you will be required to compare that to the measurements of the room you are going to place it in. All you need to make sure is that the square footage rating of the device is equal or greater than the size of the room you’re placing it in.

There is also a way you can measure the square footage of your room. You need to take the measurements of the room like the length and the width in feet. Now you have to go ahead and multiply these numbers, for instance, 10” x 20” rooms = 200 sq. ft.

CADR ratings of Air Purifier

The Clean Air Delivery Rate is a rating that was created by the Association of Home Appliance Manufacturers, also known as AHAM. This rating was developed to help the consumers know how fast a particular air purifier can clean the air in a room. Manufacturers are required to enroll for the AHAM test and get certified in order to flaunt this rating on their products.

In very simple terms, the CADR rating is going to help you understand how big a room a particular air purifier can tackle smoothly while maintaining a particular speed. This rating is taken in cubic feet per minute also known as CFM. This measurement is generally for pollutants like pollen, dust, or smoke as they are not only small but are highly allergenic.

Weight, Portability, and Noise

Air purifiers are heavy machinery and they can take up a lot of space. If you are looking to accommodate one machine for multiple rooms, then you need to get yourself a lightweight and mobile device. Some of the air purifiers come with caster wheels and that can help you immensely in the portability of the machine.

Another thing to put your attention to is the noise emission level. If you’re planning to sleep with the air purifier on, you have to choose one that does not cause a lot of disturbance during your sleep. Most of these devices will come with a fan and thus you will be able to adjust its settings and noise accordingly.

Cost of Maintenance

You simply cannot overlook the cost of maintenance of your air purifier. Before you get your hands on any purifying device make sure to grapple on the cost of keeping it running smoothly once you have bought it. Most purifiers that come with HEPA or Carbon filters will require replacement frequently. As these filters trap even the smallest particles, they tend to clog up quickly and will lose efficacy with time.

While HEPA or Carbon filters will last you only for about a year, you will not have to worry about the maintenance of Ionic or Ozone generators. These filters can be washed and used again as per requirement.


Checking the warranty of any air purifier is of utmost priority when you’re making a buying decision. Warranties help you navigate your way out of uncertainties and avoid any future issues with the machine. You must look for manufacturer warranties to safeguard your hard-earned money against defective pieces.

As air purifiers are a long-term investment, you do not want to get stuck with a device that dies within a month of your purchase. Electronic devices are very unpredictable and you require a valid warranty to protect the repair and replacement of the product if it turns out defective.
