Air Purifiers Buying Guide India – How to Buy the Right Air Purifiers?

Here are some of the important factors that should be considered before purchasing an air purifier:

1. Clean Air Delivery Rate (CADR):

It is the Clean Air Delivery Rate. This factor determines the time needed for an air purifier to work. It is measured in cubic feet air in a minute, which implies the amount of air purified in this duration. The CADR varies for various types of pollutants such as smoke, dust, and pollen.

2. High-Efficiency Particulate Arrestance (HEPA):

When we refer a filter as HEPA, it implies that dust and dirt can be trapped by them, based on the particle size. All ideal air purifiers have this filter to function efficiently.

Other than this, there are air purifies with activated carbon filters, pre-filters, ion, and ozone generators, all of which are explained below:

i. Pre-Filters:

It forms the initial resisting line for impurities and is generally found in AC units. the material used in these filters include some polyester material that is non-woven or foam material.

ii. Activated Carbon Filters:

They are best for VOC elimination and make a room free from any kind of odor. An air purifier with a larger carbon filter is known to perform much better. It needs to be replaced when it gets filled up with impurities.

iii. Ion and Ozone Generators:

Charged particles are emitted into the air by the ion generators, which then gets attached to impurities and fall on to the ground because of an increase in weight. The same is the case with ozone generators but you should know that inhaling ozone is neither good for health nor good for the environment.

3. Area of Coverage:

It indicates the area of the room whose air can be easily cleaned by the appliance. If you have a bigger room, select the device accordingly for better results.

4. ACH Ratings (Air Change Per Hour):

This figure denotes the number of times an air purifier exchanges the entire air in a room.

5. Cost:

There are expensive models of air purifiers but they have many features too which makes the investment worth it. Based on your need and budget, decide the best device for your home or office.

Besides the initial price, check the cost of annual filter replacement too

6. Energy Rating:

The BEE rating indicates the energy consumption of the device. One with a higher rating is preferred as you will have fewer electricity bills.

7. Noise:

Generally, fan speed leads to noise but certain devices are built to ensure noiseless operation. This is important to make sure that you sleep peacefully at night.

8. Additional Features:

This includes different speed control of fan, heating and cooling option, voice control, remote control, control through App, and wifi connectivity, an indicator to replace the filter, LED display for AQI, and various modes such as night mode among others. A smart featured device will cost a little more but you will have an amazing experience in operating it.

It is essential to know the basics of an air purifier before getting one. If you are living in a highly polluted area, this will be a good investment since it will save you from various breathing issues in the long run.

Frequently Asked Questions (FAQs)

This will depend on the air quality in your home and surrounding. In the case of the worst air quality, the replacement needs to be done more often. Make sure to replace it on time so that you can enjoy better functionality for years.
In case your device doesn’t have an alarm to indicate filter replacement need, enter into AMC with the manufacturer so that they can do it annually.

2. Is it possible to reduce noise from an air purifier?

The fan in air purifiers generally produces noise, especially at higher speeds. Smart air purifiers with the latest technology have sensors built in them to identify the impurity level and change the speed of the fan accordingly. Even at night time, you can choose the night mode for silent operation and have a comfortable sleep.

3. Is HEPA filter only enough in an air purifier?

The HEPA filter is highly efficient in removing 99.9% impurities of PM2.5. But generally, you will find other filters also equipped for better functionality. This includes pre-filter, activated carbon filter, and even UV methods for killing germs.
