Best Air Purifier in India – Buying Guide

Air purifiers are precious inventions for asthmatic or allergic patients as they provide quality air to breathe. An air purifier is an expensive appliance, and you probably don’t want to buy it every year.

Therefore, you need to take some precautionary steps before buying it. Let me explain some significant factors that everyone has to keep in mind while choosing the best air purifier for homes or cars.

1) Types of Filters –

Filters are the heart of an air purifier because the primary function (air filtration) is performed by the air filter itself. Hence, you should know the essential types of filters and which is the best, and why?

There are five prominent types of filters that are used in air purifiers; different filters eliminate different particulates, microbes, allergens, odor, etc.

A) HEPA Filters –

HEPA refers to High-Efficiency Particulates Air filters, which are the most popular and efficient filters widely used in modern air purifiers. HEPA filters are also recommended by the Department of Health, the US and are capable of trapping pollutants, dust, mold spores greater than 0.3 microns, hence removing 99.97% of contaminants and allergens effortlessly.

However, some pollutants and odors like gases, fumes, and VOCs are still untapped by the HEPA filters.

B) Activated Carbon Filters –

Activated Carbon, also known as Activated Charcoal, refers to the form of Carbon that is processed to acquire a vast area. The tiny pores are hence created and have a natural absorption or chemical reaction property.

Activated Carbon filters are a potent odor and VOCs absorber and thus removes terrible odor, fumes, smoke from the air.

C) UV Light Filters –

UV filters are best for killing bacteria and sometimes viruses because Ultraviolet Rays are bactericidal. The Ultraviolet Lamp is placed inside the filtration chamber along with other fliers of an air purifier.

Therefore, the air passing through the UV lamp gets purified further and becomes free from microbes and viruses.

D) Ionizer and Ozone Generator Filters –

The Ionizer or Ozone generator filters formulate the ions and ozone, which are charged particles. However, the particles floating in the air are neutral, whereas as soon as they come in contact with these ion or ozone charges, they also become charged.

Therefore, instead of floating in the air, the particles settle down over the room’s surface or wall, and thus the air becomes purified.

E) Electrostatic Filters –

The working principle of Electrostatic Filters is the same as ion and ozone generator filters. They also charge the particles present in the polluted air and gather them in the air purifier device itself.

Such filters are reusable and can be reused; you just need to wash them off after a few days or weeks, depending upon the level of pollution or according to your choice. Some premium quality air purifiers utilize electrostatic charge filters for cleaning the air.

2) Room Size (Coverage) –

The first most crucial parameter is to clarify whether the air purifier which you’re thinking to buy would be sufficient as per your room size or not.

Not all air purifiers cover different room sizes, and it may so not happen that you end up buying a less efficient air purifier. Hence, make sure you buy an appropriate air purifier that can provide comprehensive coverage that matches your bedroom or living room sizes.

3) CADR (Clean Air Delivery Rate) –

The CADR is a significant matrix that shouldn’t be ignored while buying an air purifier. The CADR refers to the amount of purified air, typically measured in M3 (Cubic Meters) per hour.

In other words, it is the air delivery capacity of an air purifier. If the CADR value is high, the machine is supposed to be more efficient and vice versa. It doesn’t mean that you should always consider a high CADR value air purifier. Instead, you need to buy it according to the pollution level and size of your room.

4) Air Change Rate (ACR) –

As the name suggests, ACR is the rate of change of polluted air inside your room. In simple words, how many times the air purifier cleans the room air per hour.

Typically, the ACR of an air purifier varies from 2-4 depending upon the brand to brand. Suppose the ACR value of an air purifier is two that means the machine changes the room air every 30 minutes. We recommend that you should buy a device with a high ACR value to ensure clean and healthy air all the time.

5) Air Quality Indicator –

The reporting pattern of an air purifier is also a vital aspect while buying it. Most of the brands possess the air quality indicator, which represents the status of air quality inside your bedroom.

Some air purifiers use different lights to represent air quality; however, premium brands like Dyson provide historical data along with graphs to report air quality.

6) Running & Maintenance Cost –

Air purifiers are used for a longer duration, primarily when you reside in an industrial or highly polluted locale. Hence power consumption becomes another vital criterion. Typically, air purifiers run on 50 – 70 watts, and if you are planning to use them for 10-12 hours every day, you should choose a relatively low power consumption air purifier.

A filter is the primary component of the air purifiers and often requires cleaning, maintenance, and replacement. The frequency of cleaning and replacement of filters typically depends on the filters used in the air purifier.

HEPA and activated carbon filters need to be replaced more frequently; however, Ionic and electrostatic filters don’t require replacement but shouldn’t be damaged physically.

Therefore, if you are buying an air purifier, you can’t ignore these two important factors. Otherwise, it will always cut down your pocket.

7) Noise Level & Portability –

Since air purifiers run approximately all day, typically in bedrooms, their noise strikes in mind and sometimes becomes quite irritating. Hence don’t forget to check the noise level produced by the device.

Please keep in mind the air purifiers using Ionic or electrostatic or UV filters don’t have fans installed. Hence they produce almost negligible noise.

Air purifiers are not small appliances, and if your plan is to use a single air purifier in multiple rooms such as living room, guest room, or bedroom, you should buy a lightweight or trolley-built machine. Thus it can easily be placed from one location to another.

8) Brand & Price –

We always recommend that one should buy the product of the most reliable and reputed brands in their segment. However, such brands who have made a very positive reputation in the market will definitely cost you more. But eventually, you will realize that you made the right decision at that time. The one-time investment is far better than lifetime tiny expenses.

However, we don’t deny that you shouldn’t check your budget before buying. That’s why we made the above list of the Top 10 best air purifiers in India so that you may purchase the right product according to your budget and requirements.

What is the Air Quality Index (AQI)?

The Air Quality Index refers to an index (value) from 0 to 500 that represents air quality levels in the region or cities. Different cities have different AQI values, which indicates the pollution level in the town. If the AQI level is below 100, the quality of air is supposed to be acceptable. However, if the AQI value is 300 or above, the air quality of that region would be considered hazardous.

For each pollutant, such as PM2.5, PM10, O3, NO2, and CO, the AQI value is given. You can refer to which pollutants are more hazardous in your city and which are satisfactory.

We always advise that you check the Air Quality Index (AQI) of your city (region) before buying any air purifier because it might be the case that you don’t even need an air purifier.

You will also come to know which pollutants are more dangerous and need to be focused on. In this way, you choose an efficient air purifier that you exactly require. People sometimes buy an expensive and best air purifier even if they don’t need it, hence keep AQI level in mind while purchasing an air purifier.
