Air purifiers are effective tools for dealing with air pollution. Breathing clean air will help you lead a healthy life and prevent conditions such as high blood pressure. Various pollutants must be removed from the room to complete the air purification process. The position you place your air purifiers affects how well they work.

Here, we look at the best location for your purifier, common rooms with pollutants, maintenance methods, and many more. Read on to learn this and much more.

What Common Pollutants Can an Air Purifier Clean in Your Home?

Many airborne pollutants, like gases and particulate matter, can be found in your home. When disturbed by airflow or human activity, these areas can quickly accumulate pollutants and release them into the atmosphere. 

Here are the most common pollutants in your house;

  • Dust
  • Dust mites
  • Pet dander
  • Mold spores
  • Pollen
  • Volatile Organic Compounds

Which Is the Best Place to Put an Air Purifier

Knowing where to place an air purifier once you buy it is important. The position you place the air purifier will determine whether it cleans air effectively or not. Which is the best location you can place your air purifier? Let’s take a look.

Near Pollutants

You should put an air purifier near the source of pollution; wherever there is a high concentration of pollutants, an air purifier should be installed. An air quality monitor is usually used by a specialist in air quality to determine where the pollutants are concentrated. 

This is how you can identify pollutants and place your air purifier near them. 

 Your eyes

It’s easy to see contaminants like smoke and mold. Put a mold air purifier close to the mold infestation for best results and clean air.

Could you place the air purifier close to the smoking area? When using strong air purifiers to deal with wildfire smoke, place them closer to the windows where the smoke enters your home.  


Bad-smelling air or odor is a definite sign of a high concentration of air pollutants. They include tobacco smoke or oil smoke. 

Allergic reaction

Do you experience allergic reactions when in the kitchen or your home? These symptoms show a higher concentration of allergens in your home. Placing an air purifier in such places will help deal with the problem.  

 The air purifier can give you fresh air and improve indoor air quality when placed close to the most affected areas.

Places With High Air Flows

Air purifiers draw in large volumes of air to remove airborne pollutants and recirculate clean air into the space. They must therefore be positioned to draw air from all room corners quickly.

Placing an air purifier in a room’s corner, up against the wall, is the biggest mistake people make. As a result, there needs to be more airflow, which has limited outcomes.

Placing an air purifier close to a doorway, window, or particularly on a wall where air moves makes a lot of sense.

More pollutants and particles are also present in moving air. This is so that there is vertical air movement in your home. This loosens all the dust and other particles your house can accommodate.

Pollutants from the outdoors that might spread throughout your home can be stopped if you put an air purifier close to entry points. The entry points include front doors or open windows where there is maximum airflow.

Pet Areas

Setting up an air purifier in pet areas is easy. The only requirement is to put the device closer to where the pet typically lives or urinates. For instance, if you have a cat litter box, placing it nearby is a great idea.

But remember that animals don’t have a high tolerance for pain. So, ensure the air isn’t blown directly at your pet.

In Living Rooms

The living room is frequently the most crowded space for many people because someone is always present. An air purifier in the living room is important because it’s the most polluted area compared to all the rooms.

Although the center of the living room would be the perfect location for an air purifier, there are better options than this.

You should be able to place the air purifier where people frequently step because the living room can become dusty from frequent movement. The air purifier will be able to get rid of airborne dust particles.

Overall, each situation will determine where to place the air purifier in the living room. But you get more clean air when you put closer to the source.



It is well known that basements are musty and damp. These conditions can encourage the growth of mold and cause allergies. As a result, using an air purifier in this setting is a great idea, but the placement can affect how it works.

Place the air purifier close to the mold’s source, usually near the moldy wall. This way, the cleaner can deal with these bad odors. Air purifiers will also stop new mold growth on the wall by capturing airborne spores.

Elevated Points in the House

Indoor air circulates in two directions: It can either be vertical or horizontal. Elevating an air purifier allows you to capture horizontal and vertical indoor air movement. The desk is a convenient place for a small air purifier.

Mounting an air purifier on a wall is the perfect placement. Wall-mounted air purifiers are usually up to 5 feet off the ground and can access the highest airflow areas.

Air purifiers have plenty of air available when placed in a higher position. Air is easily sucked into the device, and purified air is released.

Placement on a wall is perfect for air purifiers. You must elevate and secure it, of course, to hang it from the wall.

Where to Avoid Placing Air Purifiers

There are some locations you must avoid placing an air purifier. Let’s take a look at some of them;

Close to Walls/ Near a Corner

It is not a good idea to place your air purifier near a wall or a corner. It has the least airflow. An air purifier cannot effectively purify the air if placed in a corner. 

There might be excellent air quality there. However, the quality of air in the other rooms would not be as purified as it would have been with a proper air purifier placement.  

A corner is not a good place to put an air purifier. An air purifier’s ability to effectively purify the air is affected when placed in a corner. 

Here are three factors that make a corner or near a wall the worst place for an air purifier: 

  • It can impede airflow. 
  • Air vents are blocked in both directions. 

The ability of air purifiers to perform as intended can be affected when placed in a corner or near a wall.

Places With Obstructions

You want the air purifier’s air flows to be unblocked. An air purifier could be placed in free spaces behind the TV or furniture. Please do your best to resist the urge to do this. An air purifier will operate at its best when placed at a 3 feet radius from any other item.

Books frequently cause another issue. An air purifier improves indoor air quality. People naturally prefer reading in an outdoor setting, which makes sense.

However, a stack of books near an air purifier, especially in a library, could prevent it from working at its best. The books might block the air intake.

Generally speaking, try to give the air purifier some room. It will work more efficiently and better when it is not blocked by anything.

Humid Areas

Air moves slower in places with high humidity. The Air purifier will have a hard time cleaning this air because;

  • To create airflow with heavy air, an air purifier requires more energy. 
  • Filters’ capacity of most air purifiers will be decreased by humid air. 

An air purifier would not work well in the following two locations in our home: 

  1.   Kitchen. Cooking produces kitchen smells. In the kitchen, boiling water will increase the humidity, making it more difficult for an air purifier to do its job. 
  2. Bathroom. Showering can cause the relative humidity to go higher than 90% due to excess moisture. That humidity level will make it harder for the air purifier to work. 

Mold grows in places with high humidity levels. Bathrooms are where you can find mold, which later turns into mold spores. You can combine it with an air purifier when you aren’t using the bathroom. Always remember that the humidity should be lower than 50%.

Near Heat Sources and Electronics

Avoid placing your air purifier close to heat sources like electronics or radiators. They can release heat and affect the device’s performance.

Air purifiers should not be placed close to electronic devices. Some smaller purifiers may be affected by these electronics.

Factors That Determine Air Purifier Placement Positions

There are factors to consider before placing air purifiers at certain places in your home. Not all air purifiers are the same; different measures must be considered before placement. Here are some of them:

The Size of the Room

To use your air purifier correctly, you must first determine the size of the room. Simple rules apply: your air purifier won’t perform at its best if you buy one with a smaller coverage area than your room. However, investing in a powerful air purifier may be a waste, especially if you have a small room.

It’s advised to use an air purifier with a minimum rating of 4.8 times an hour to clean the room.

Therefore, to make sure you choose one that is appropriate for your room size, carefully review the manufacturer’s recommendations and look for CADR and Room Coverage ratings before buying.

The Air Purifier Type

Let’s look at the airflow and filtration technology of different air purifiers. It’s important to understand that every air purifier draws air in and releases it differently. As a result, when choosing a placement location, it is crucial to consider the airflow.

Another factor to consider is the filtration technology used by the air purifier. For instance, you should install an air purifier with an activated carbon filter in a space where people smoke or exposure to various VOCs.

Noise Levels

The noise an air purifier makes is one of the things to consider before installation. A specialized tool can be used to measure the noise level. The devices’ ability to reduce noise depends on the motor quality used.

All these factors are important because loud air purifiers can be a problem, especially in the living room and bedroom.

Proximity to Power Outlets

Air purifiers need to be plugged into power sources to run. However, most air purifiers have a power cord that needs to be longer. They range from 80 centimeters to 2 meters. It is important to consider your power outlets when choosing where to place your air purifier.

The cleaner should be placed in a way that it won’t be a tripping hazard to people passing by. You will not need an extension cord which will significantly reduce the risk of accidents.

How to Improve an Air Purifier’s Efficiency?

An air purifier’s efficiency affects how it works and performs in your home. Here are some tips to improve your unit’s efficiency and keep getting clean air.

Moving it Around

We can clean more air by moving an air purifier across different rooms. Doing this improves its performance. An air purifier can be more effective by moving it around a room than placing it in one spot.

Regular Cleaning and Maintenance

For the device to remain highly effective, it is important to keep it well-maintained. This involves cleaning the pre-filter and changing the filters regularly. The maintenance requirements are different depending on the model. Refer to the manufacturer’s recommendations to carry out maintenance.

Run It Continuously

Continuously running an air purifier will increase its effectiveness and efficiency. You should use a low setting on your air purifier if you plan to use it constantly.
