Where to Place Air Purifier?

The market for air purifiers has seen steady growth in recent years, driven by increased awareness of the health risks associated with indoor air pollution and the growing popularity of smart home technology. However, we rarely place our air purifiers in the right location. To improve the performance of an air purifier, where will the air purifier manufacturer tell the air purifier to be placed?

How to Place the Air Purifier?

After buying an air purifier, many users tend to place it somewhere out of sight and let it work alone. However, air purifiers may work differently in different places, so it is very important to know where to place an air purifier. The following information may help you.

It is recommended to place an air purifier no higher than 5 feet off the ground, as it can not only eliminate the risk of tripping but also enhance its vertical cleaning ability by capturing airborne impurities closer to the ceiling in a swifter manner. To save space, a wall-mounted air purifier is also recommended.

Air purifiers work by pulling large amounts of air towards the device, filtering it to extract the pollutants in the air, and then distributing the purified air into the surrounding environment, which means they need to be placed in areas with more air circulation to avoid Airflow is not working.

Electronics operating on comparable frequencies may interfere with each other, so it is recommended to keep air purifiers away from televisions, microwaves, and audio systems to prevent disruptions.

Place the purifier near the problem area to achieve the purpose of cleaning the air, and ensure that the air purifier is not obstructed from the top during operation as most models take in air through this area.

The Do’s and Don’ts of Air Purifier Placement

By following these Do’s and Don’ts of air purifier placement, you can ensure optimal performance and a clean indoor environment.


  • Place the air purifier near the source of the odor or contaminant to allow it to circulate air more efficiently.
  • Keep it away from obstacles: Air purifiers need adequate supply and return of air to function properly, while obstacles can block air circulation and limit the purifier's effectiveness, so remember to keep it away from obstacles.
  • Keep it away from direct sunlight: Direct sunlight can affect the performance of the air purifier and can also cause the plastic casing to discolor or warp.
  • Pay attention to the room and unit size: If you have a larger room or multiple rooms, more than one air purifier is more considerable, as well as the device’s CADR.
  • Keep the purifier about 6 feet away from any electronics to avoid the interference of each other’s performance.


  • Don’t place it near humid areas: Air purifiers should be kept away from areas with high moisture such as bathrooms or kitchens to avoid damaging the internal components of the air purifier.
  • Don’t put it in a corner: Placing the air purifier in a corner can obstruct the airflow and decrease the speed at which the device can intake and purify the air within the space.
  • Don’t put it on a dusty surface: Placing the air purifier on a dusty surface can cause the filter to clog faster, which will reduce the efficiency of the unit.

Tips on Improving Air Purifiers Efficiency

The following five tips may help you maximize the performance and functionality of an air purifier.

Choose the right size: It is important to choose an air purifier that is the right size for the room. A unit that is too small for the room will not effectively clean the air.

Keep windows and doors closed: Make sure to keep all windows and doors closed while the air purifier is running, which will prevent outside air from entering and allow the device to focus on cleaning existing air.

Make sure the unit is clean: Air purifiers will lose their efficiency over time, so you need to regularly clean the air purifier filters to ensure the unit functions well. For example, for air purifiers with HEPA or carbon filters, it is recommended to replace the filters every year. What’s more, to keep the purifier’s body clean, a microfiber cloth is advisable.

Consider adding plants: Certain types of plants, such as snake plants, can help naturally purify the air in your home and supplement the air purifier's efforts.

Keep air purifiers on: Maintaining clean air in your living space requires continuous effort as air circulation fluctuates constantly. 

Use in conjunction with other efforts: Using an air purifier in conjunction with other efforts, such as keeping floors and surfaces clean and vacuuming frequently, can also help improve indoor air quality.

How Do Air Purifiers Work for or Help With Smoke?

Dida Healthy air purifier supplier tells you how an air purifier cleans up smoke. Air purifiers mainly consist of filters, all of which work together to ensure the normal operation of air purifiers.

lFilters: Generally, filters can be further divided into three types and perform different functions. The pre-filter is typically made of a porous material such as foam, mesh, or non-woven fabric. They work to capture larger particles such as pet hair, dust, and other pollutants from the air before the air passes through the HEPA or activated carbon filters, so that the HEPA or activated carbon filter life can be extended and the air purifier can work more efficiently. Usually they should be cleaned or replaced every 1-3 months. An activated carbon filter is a unique filter that consists of a highly porous material that can open millions of tiny pores between carbon atoms after being treated with oxygen. Therefore, when air flows through the filter, gases and odors become trapped in these pores and won’t be released back into the air. Usually a thicker filter or one with a higher density of activated carbon will be more effective at removing odors and VOCs. HEPA filters are made of a dense mat of randomly arranged fibers, especially fiberglass. When air flows through the filter, dense fibers cause the air to change direction and particles as small as 0.3 microns get trapped in the fibers.

lUV-C Light: Some air purifiers use UV-C light technology to destroy germs and bacteria in the air, which is especially beneficial for those who are allergic to smoke or have respiratory problems.

Ionizers: Ionizers attract and trap pollutants in the air, including smoke particles. They work by emitting negative ions into the air, which attach to smoke particles and other pollutants to make them easier to capture in air purifier filters.

However, no air purifier can completely remove smoke. Once you choose to use the best air purifier (or even to quit smoking at home), you have to clean and disinfect your house to get rid of odors. As a professional wholesale air purifier supplier, Dida Healthy can introduce a variety of air purifier types for you, please choose the appropriate product to purchase.
