This post highlights essential notes on how to keep an air purifier in a good spot. But to find the perfect place, there are a few questions to ask yourself.

Air pollution is one of the biggest challenges many countries across the globe are trying so hard to combat. While that is still being handled, individuals have the responsibility to fight against pollution as it affects each of us. Researchers say that poor-quality indoor air is one of the factors increasing mortality worldwide. This means we need to pay more attention to battling it. Air purifiers are designed to help achieve this goal, and here we will tell you the best place to put an air purifier at home.


It’s more than just getting an air purifier; it’s also about ensuring that it is placed at a convenient location where it can serve its purpose effectively. It is essential to know that placing an air purifier in the proper position increases its efficiency by about 25%- 35%. That is a huge difference.

What is the estimated size of the room?

The room size should be calculated because it plays an important role in the air purifier’s choice, model, size, and capacity.

It is important to know that not all purifiers function in the same capacity. Some are built for smaller spaces and can only purify about 10 square meters. This means that it will not work efficiently when placed in a room of 40 square meters space.

When buying an air purifier, the size of the room will influence the CADR number specified on the device. The higher the CADR, the faster air will be purified in the room, and the better it will eliminate certain air pollutants.

Tips on where to place an air purifier

There are many speculations on the ideal place to keep an air purifier. Can it be placed on the table, shelf, or floor?

Follow these valuable tips and find the best place to put an air purifier.

1. Keep the air purifier away from humidity

Although it may seem that bathrooms and kitchens are the rooms that need it most, it would be best to know that there are better ideas than an air purifier for such spaces. Bathrooms are particularly humid with thick and moist air. In addition, high humidity can affect the performance of HEPA filters.
A good strategy is not to place an air purifier in the bathroom while you are bathing but when the steam disappears, and the humidity is no longer felt.

2. Consider the principle of diffusion

When considering the diffusion principle, the best place to position an air purifier is at the side of the room with the most open space. This principle of diffusion describes that the particles in the air will circulate across the room at equal distances from one another.
Therefore, as the air purifier sucks in air, the particles in the air begin to fill up the gaps they originally had. And as the clear air is released, it will circulate across the room.

3. Obstructions and obstacles should be avoided

It’s crucial to ensure the unobstructed flow of the air to and from the purifier. It is then important not to cover the vents and not to place the device directly against the wall or a corner.

4. Ensure to place it away from sources of heat

Just like most machines, an air purifier will get heated when during its course of operation. This is due to the mechanical mechanism it runs on, producing heat.
So, to avoid overheating the air purifier, place it away from heat sources. Placing your air purifier around other appliances that emit heat is also not advisable. It will help if you put an air purifier where it is not at risk of overheating.

5. Close windows and doors

It is often thought that opening windows and doors is a good idea to remove pollution from home. However, by opening them, we are letting in more pollutants.
It is therefore recommended to use the air purifier with the doors and windows closed for more effective operation.

Summary of the best place to put an air purifier

In addition to knowing how efficient an air purifier works, you might ask if it’s okay to leave it on all through the night. YES, it is entirely okay to leave it on all night. Air purifiers are created to work all around the clock (day and night).


Air purifiers come in different types, models, and designs. Some can work all night, while some are not. So, ensure that you buy a good product and try your best to keep your air purifier in a suitable place.
