Buying Guide

With the COVID pandemic, the demand for air purifiers has increased because people want to keep their indoor living space free from germs and viruses. Life in quarantine can be difficult as you cannot leave your home. Therefore, it is necessary to do something about the air quality in small apartments and living rooms as you are going to be spending so much time indoors.

There are so many companies coming up with different models of air purifiers, which can be a bit intimidating. Before buying an air purifier, you must consider important questions such as do you want a bigger device or smaller device to fit into your room and what your budget will be. We have explained some important factors about purifiers that you must consider so that your money does not go to waste.


Air purifiers come in all kinds of sizes and shapes; some are huge and slim, while others are compact and portable. If you live in a small apartment, then a tabletop air purifier is ideal for you as it will occupy less space. These purifiers are compact and are available at affordable prices, so you don’t have to spend too much on them.

On the other hand, if you have a family and large living room, then you must consider investing in a large-sized air purifier so that it can take in more air and supply fresh air after filtration. Such air purifiers are a bit pricey, but they come with extra features so that you can get the maximum benefit from them.


Noise is a significant factor to consider when choosing an air purifier. Most air purifiers work silently at the lowest fan speeds but the noise level increases as you increase the fan speed. It is recommended to choose an air purifier whose sound level ranges from 20 to 50dB(A).

A purifier that is loud even at the lowest fan speed will make it hard to sleep at night and will be too noisy to make conversations. So it is ideal to go for an air purifier with a sound level lesser than 50dB(A).

Useful Features

Some air purifiers have useful features such as air quality indicators, which lets you know how good or bad the air quality is by using the built-in sensors. Such sensors let you know when to increase or decrease the speed of the fan.

There is also an auto feature provided by some purifiers, which automatically changes the speed settings depending on the present air quality in the room. These features can help you use the purifier in the most effective way. So try to look for such features in air purifiers to make your task easier.


When it comes to using filters, some companies use the three-stage filtration process while others use as much as 5 filters. For large rooms occupied by several people, it is better to have more filters to get rid of all the allergens, pet hair, odor, and bacteria particles from the air.

The efficiency of the HEPA filter holds great value when it comes to purifiers. Try to look for the true HEPA filter air purifiers as these have high efficiency for getting rid of harmful bacteria and germs. Clean Air Delivery Rate (CADR) is another important aspect of air purifiers that should be considered before making your pick.

The higher the value of this metric, the more efficient it will be at removing unwanted particles. It tells you how much clean air can the device supply to replace the concentration of the unwanted airborne particles. So always compare the CADR values when choosing between two purifiers.


Air purifiers can massively improve air quality indoors and get rid of unwanted particles. Therefore, it is necessary to invest in such devices so that you don’t have to worry about virus carriers making their way into your living space.
