Text Size:

Air purifiers will surely become a part of every home soon, with the decreasing air quality making it a must-have for indoor use.

During the pandemic, a large number of people are spending time indoors. So, we have to safeguard the indoor air quality. And for that, an air purifier is necessary.

But do you know which air purifier is worth buying?

Don’t worry. We are here to guide you. We will answer your question ‘what should I look in an air purifier?’

Let’s start!

Why purchase an air purifier?

As discussed earlier, if the pollution increases at the same rate, every home will require an air purifier soon.

While this is the main reason for buying one, there are other reasons too.

This is what an air purifier does:

  • Removes dust, pollen particles from your home.
  • Soaks away the pet dander, mould, odour, ragweed, virus, and much more.

These two are the main uses of air purifiers. But what happens if these particles remain in the air you breathe in?

  • It will be harmful to patients who get allergies from minute or microscopic particles.
  • Asthmatic patients will find it hard to breathe in the air consisting of these microparticles.
  • If there is smoke spread around and an allergic patient or asthma patient has to survive, the air purifier will help them. It soaks smoke particles as well and helps in cleaning the air.
  • Having pets at home sometimes makes your home full of odour. For instance, your home is smelling bad and suddenly someone important visits your home! An air purifier will not only remove the odour of pets but also other odours found in a home.

Choose the correct air purifier filter type

It is the main point that you should take care of before buying the air purifier.

There are multiple filters available in the market. Let’s check each of them.

HEPA: A HEPA filter is the most selected air purifier in the market. But this filter is to be changed after one year (depending on the use)

Activated carbon filters: This filter is also used in many places. It needs to be changed or washed after six months.

Pre-filters: This type of air purifier filter has to be usually washed or changed once in three months

What should be the size of the air purifier machine?

Looking for the right size of the air purifier? First, you need to count the square footage of the place where you want to put the air purifier.

If your main concentration is on the asthmatic patient, always check for the air change per hour (ACH) rate of your buying model.

ACH means how many times the air of the room is changed in one hour by the air purifier.

Generally, if the air is changed four times in an hour, it remains best for asthmatic patients.

Now comes the main concern: How to check the size of the air purifier required?

There are four types of air purifiers based on their size and efficiency:

Small air purifiers: These machines are made for a personal room measuring up to 299 square feet.

Medium air purifier: These machines can work efficiently for the rooms or place that measures around 300 to 699 square feet.

Large air purifier: These machines are efficient for the rooms or halls measuring 700 square feet to 1,900 square feet.

Whole-house air purifier: As the name suggests, it will be helpful to purify the air of the entire house. It will be larger in size, and efficient, as well as costlier.

Main features to keep in mind while buying air purifier

Here are some special features that you have to keep in mind after choosing the proper size. Have a look:

  • It should be an energy saver and also not harmful to the environment
  • There are wi-fi-controlled air purifiers available in the market. Go for it if you want
  • It should constantly display the air quality in the room or hall where it is placed
  • Choose the air purifier with caster wheels, easily movable, remote controls, filter changing time indicator

Where to place the air purifier?

Actually, deciding the place of the air purifier is the first step. Because according to it, you will be able to choose the size of the air purifier.

But if you still have not decided the place, here are some points that might help you:

  • Put the air purifier in your bedroom. It is because it will help you to get sound sleep as well. And you also spend most of your time there, it will be beneficial
  • You can sometimes place it in the hall when you are expecting guests. They might be allergic to some odour or particles of your home. Or, they might carry some infection with them. So, your air purifier will work for both situations


The points mentioned above are the main reason to buy a portable air purifier or machine with wheels.
