Buying Guide for Best Air Purifier 2021

Having listed the best air purifiers for the year 2021, it is mandatory to tell you about the things that must be noted while buying the air purifier from any source. Before you buy your air purifier, make sure whether that machine suits your requirements or not.

So, to give you a clear idea about the factors that should be noted before buying the machine, I am going to add an effective air purifier buying guide. If you comply with this guide while buying this machine, hopefully, it will come up with all your expectations from this machine.

Therefore, sticking to my topic of air purifier buying guide, here are the factors that you should check before you finalize a machine for you.

Air Purifier Buying Guide

Size and Weight of the Purifier

Checking the size and weight is the first and most common factor of buying your purifier machine. If you buy a machine with heavyweight, you might find yourself in trouble while moving that from one place to another place.

On the other hand, if the machine is light in weight, you can place it anywhere in your house where you feel that it should be.

Similarly, the size of the machine plays an important role in determining its worth.

If the machine’s size is normal, you need not worry about placing this machine anywhere in the house.

But, if the machine’s size is bigger than normal, you need a considerable area to place that machine.

Especially, people who are making their living in small houses must consider these factors; otherwise, they might create problems for them other than convenience and comfort.

The noise of the machine

Most of the conventional air purifiers create disturbing noise while performing their so-called air cleaning option.

Instead of cleaning the air for you, these cleaners create a high-level sound that disturbs you while doing routine work, especially when you go to sleep.

So, it becomes evident that machines with greater sound should not be preferred in any way.

On the other hand, the machines that I have recommended above don’t create that sound level, which is disturbing for you.

Meanwhile, if you don’t pay heed to this thing, you might get your night sleeping disturbed due to your air purifier machine’s noise.

So, if you like the machine whose sound is level is between 25 to 65db, you can go with that option.

Ozone Free

Earlier, it has been seen that most of the air purifiers were using UC-V light and Ozone particles to deplete the air pollutants in the air.

But, according to recent research, it has been noted that the presence of ozone in air cleaning operation is not good for residents of the house.

Especially when you have people aging above 50 years and children whose age is less than ten years, it becomes necessary to check whether your air purifier is ozone free or not. Because, if it is not ozone free, you can bring you more harm than it benefits you

On the other hand, purifier without ozone molecules suits your requirements best, and it does not pose any threat for the residents of house irrespective of their age.

Filtration Mechanism and Life of Filter

The filtration process of any air purifier is a thing that determines its veracity and worth. So, when you make your mind up of buying an air purifier, you have to satisfy yourself after properly checking the details of its filtration mechanism.

Now, the latest air purifiers for 2021 that I have mentioned above comprise of 3-stage filtration process; HEPA filter and carbon activated filters are essential parts of these machines.

If you are looking for your purifier, the filtration process must contain HEPA Filter and carbon activated filter, as these filters make sure that these filters will successfully intercept the air pollutants, odors, and smoke in the air.

However, if your desired machine has these functionalities, it is fine to go with that option. Moreover, if you want to avoid any inconvenience, the above-given list is the best list from where you can choose a reliable and durable air purifier for your home.

Coverage Area of Air Purifier

You are going to buy an air purifier without defining the area that needs to be served using that air purifier; what do you think that how does that purchased purifier will serve your cause?

Of course, you may buy a purifier that has been designed for a bigger area, and in reverse to this, it may not fulfill your requirement due to being short in capacity.

Therefore, to avoid this situation, you must check the area that you want to be served using an air purifier, then select the machine according to your area’s requirement.

As each of the purifiers serves a specified area, so it is necessary to consider the area that needs to be served using this air purifier.


Now a day, it is a common problem to have an allergy due to air pollution. Some of you might consider ignoring this problem, but it cannot be ignored when it comes to the health of your children and parents who have now become aged and delicate against disease. So, the best solution to this problem is to have clean and fresh air free from all kinds of air pollutants and allergens.

And this is only possible if you have a good quality air purifier at home.
