An air purifier used to be a luxurious commodity in the past. It has become an essential component of many homes over the years due to its robust capabilities. The purpose of a good air purifier is to improve the air quality of any home. The device can get rid of airborne particles and unappealing odors within a short time. They also create a comfy environment by removing air contaminants. 

Knowing where to put your air purifier is a defining factor in its performance. You might lose up to 50% of your air purifier’s ability by placing it in the wrong position. But, you can also increase your air purifier’s capacity by 20% just by placing it in the right spot.

Please find out more about where to place your air purifier to maximize its functionality and breathe in clean air. 

The Worst Locations for Your Air Purifier

When figuring out the best spot to place your air purifier, it is essential to consider where you shouldn’t keep the device.

In the Center of the Room

The most crucial component in air purifier placement is providing your air purifier with enough airflow to function correctly. Placing it in the center of the room can limit its performance and ability to clean the air at maximum capacity.

The air cleaner cleans the air in front of the device and its surrounding air. Due to the way particles disperse, it’s best to put your cleaner on one side of the room. The fan’s vacuum draws in dirt from the other room parts, allowing a thorough clean.

Make sure that the air intake is clear of any blockages, as the air purifier will perform less efficiently if the air intake is blocked. Make sure the air stream discharge is directed toward the room’s center to achieve the most airflow.

Near Heat Sources

Air purifiers, like any other machine, become hot when in use. It is essential to place it away from heat sources to avoid overheating. Direct sunlight or heat can damage an air purifier from furnace vents, so avoid keeping it under direct sunlight.

Close to Moisture or Humidity

When the humidity is high, the air is heavier. Naturally, high-humidity areas are known for being excellent mold breeding grounds. In most cases, a mold infestation will begin in the bathroom.

Air purifiers are effective in removing moisture from the air. However, too much moisture can cause your air purifier to malfunction. For practical functionality, keep in mind that relative humidity should be less than 50%.

Too much moisture absorption can shorten the lifespan of your air purifier’s filter. To avoid condensation damage, ensure it’s not close to any sources of moisture. You can also employ the option of a dehumidifier in this situation.

Next to Electronics

It’s also vital to keep your air purifier away from electronic devices as some electronics that run on similar wavelengths can cause interference. So, keep them away from televisions, stereo requirements, and microwaves. When they’re situated near your router, they can also cause your WiFi to lose signal. 

The impact of your air purifier on your devices depends on several factors. Sometimes a little trial-and-error approach is required, primarily if you use an ionic air purifier. But, make sure electronics are at least six feet away from your air purifier. 

Ionic air purifiers produce charged particles that bond to filthy air particles; therefore, placing one near electronics is bad. The dirt particles in the air will drop on the closest surface as the charged particles bind to them.

The Best Locations for Your Air Purifier

When you find yourself wondering, “where should I put my air purifier?” your primary goal may be to maximize the airflow through your purifier. Here are some spots where you can place your air purifier to achieve its maximum capacity.

Living Room

If you spend a lot of time in the living room, putting your air purifier, there might be your go-to option. Your living room has one of the best sources of air infiltration in your homes, such as by the door or windows. 

Since dirt particles from outside have the possibility of coming inside your home as people enter and leave, it may be helpful to place them near the front door. If you position your air purifier close to the door, your device can filter the unclean air outside before it enters your home.

Make sure the air purifier you choose for the living room is large enough to filter all the air in the space. Since the living room is generally the largest in the house, the air purifier’s cleaning capability must be adequate for that space.


Air pollution can affect sleep duration, according to a study. There are several ways air pollution might disrupt sleep, such as the increased risk of sleep-disordered breathing. Dirty air particles in the bedroom might disturb your respiratory system and even impair your sleep. As a result, it’s critical to keep the air in your bedroom clean.

If you spend the maximum time in the bedroom or work there, it might be the ideal location to place the air purifier. Make sure you create enough space between the device, the walls, and other obstacles. Although this might be difficult in a bedroom, you should always aim for your air purifier to have enough room to operate without obstructions.

Your kitchen is likely a breeding ground for various odors and spores. Putting your air purifier there will help you displace odors before they spread throughout your home.

Food particles, mold, and cooking residues are all sources of pollutants in the air. Smoke is one of the pollutants that can affect the air quality in your kitchen when you’re cooking. If you cook regularly, your air purifier’s filter may need to be changed more frequently.

But, if you’re going to put your air purifier in the kitchen, it should be close to the trash can. Smoke, oil, and food particles will quickly gather in the filter of your air purifier. Ensure that your air purifier is free from any object and heat sources. 

Using a carbon pre-filter will also help your air purifier remove aromas from the kitchen. Carbon pre-filters overcome odor particles, ensuring that no odors are released into the air in your kitchen.


The basement is often a neglected section of your home, often dirty, dark, and damp. Mold spores could form due to the increased wetness, which is a severe health risk for those close to the basement. 

You can avoid mold and pollutants with an air purifier. This will preserve the quality and integrity of stored items like books and furniture. However, there are additional ways to remove musty basement smells.

Can You Put Air Purifier in a Corner?

Place the air purifier in an area with a high exchange of airflow. The airflow is lowest in a corner, reducing the device’s effectiveness. You can lose your air purifier’s maximum capacity if you place it in a corner. 

Should I Run My Air Purifier 24/7?

Since an air purifier works just like other appliances in your home, it can be expensive to run it all the time if it is not needed. Even if you’ve found the perfect placement for your air purifier, it is best not to keep it running all day and night if you’re not home. If you spend all your time at home, it is safe to keep it running 24/7. However, if you spend time outside your home, it is best to keep it off during those times. You can use the formula below to calculate the potential costs of running your air purifier 24/7.

Cost = Power Consumption of the unit (kW) x Rate of Electricity ($/kWh) x Hours of Operation

It is also important to remember that an air purifier alone cannot transform your home. It would help if you also were consistent with cleaning your home by vacuuming, mopping, and dusting regularly. Cleaning all aspects of your home will contribute to a cleaner environment.
