Where To Place An Air Purifier In Your Home

Air purifiers are used to remove impurities in the air that we breathe. These devices are especially useful to people who suffer from allergies from dust, pet dander, and smoke. However, the location where you place the purifier can impact its ability to remove these pollutants.

Where to place an air purifier in your home? The air purifier should be placed in the room where you spend the most time, like a living room or bedroom. Or you can place them in a room where the air quality is a problem. Air purifiers require one to two feet of space on all sides in order to operate efficiently.

Where you place your air purifier can depend on many different situations. Whether it is to eliminate food odors in the kitchen or remove airborne particles from the bathroom, it is important to understand what you want to use an air purifier for when deciding where to place it. Here is what you should know about air purifier placement.

Where To Place An Air Purifier In Your Home

Which Room To Place Air Purifier

When deciding where to put your air purifier, you should consider where you will benefit the most from it. Typically, you should put it in the room that you spend the most time or where the air quality is the worst.

Here are beneficial places to keep the purifier:

  • Bedroom – You should choose this room if you have bad allergies while you sleep. This room is also beneficial because this is where you breathe the deepest. Having an air purifier on while you sleep will help you wake up with clear nasal cavities.
  • Living room – Having an air purifier placed in your living room can help eliminate dander, pet hair, and other allergens in the air.
  • An area where a smoker is – If you place the air purifier where the odor from a smoker subsides, it can help suck up those impurities. (You may also want to check my air purifier for smoke review.)
  • Kitchen – Keeping the air purifier in the kitchen will help eliminate the lingering odors that come from cooking.

 Air Purifier Placement

Once you have figured out whether you’ll be placing the air purifier in your bedroom, living room, or kitchen, you can then figure out the best placement for it. Typically, the best place for one would be in the center of the room without any object or furniture preventing air from reaching it.

But most people rather not place an air purifier in the middle of the room where it can be a tripping hazard or an eyesore. So other places the purifier can go are:

  • Against a wall
  • Behind the sofa
  • Near the door
  • Kitchen
  • Bathroom

Near a Wall

Placing an air purifier near a wall or in a corner is the next best option as it will still allow the device to trap those airborne particles in order to keep the air fresh and clean. Make sure to keep one to two feet of space between the wall and the air purifier and keep the intake vent facing toward the center of the room.

Having your device tucked away near a wall will prevent it from becoming a trip hazard and dangerous.

Behind a Sofa

If there is a smoker in the household, keeping an air purifier near the couch or chair where the individual smokes is an effective way of removing the tobacco smoke from the air and reducing the odors that are associated with smoking.

An activated charcoal device uses a technology that purifies the air by absorbing toxins into itself rather than allowing the toxins to remain in the surrounding atmosphere. When you opt for this kind of purifier, you will need to dispose of the activated charcoal and replenish it from time to time.

Near the Door

A good way of helping to reduce irritants from entering the home is to place the air purifier near a door. The purifier will work as a shield against bacteria and other microorganisms; this is especially helpful for people who suffer from asthma and other allergies.

It is also possible to place an air purifier in a doorway into another room to help filter out and prevent any irritating particles from entering that room. This is especially helpful when you have cats in your home, even though you are allergic. The purifier near a doorway can prevent the cat’s dander, hair, and odor from entering that room.

When placing an air purifier in a doorway, make sure the front is facing the opposite of the room you want to guard.

Kitchen or Bathroom

The two rooms that harbor the most bacteria and odor are the kitchen and bathroom. Placing the air purifier in the kitchen can help keep pet dander from reaching the foods you are cooking while keeping the odors from your food prep from seeping out of that room and into the rest of the house.

Mold spores thrive in damp and humid areas such as a bathroom, so having an air purifier in the bathroom can help prevent bacteria and mold from spreading.

Tips for Increasing Effectiveness of an Air Purifier

Placing the air purifier in the right spot is the most important factor for increasing the effectiveness of the device, but there are a few more ways to help increase their effectiveness.

  • Keep doors and windows shut
  • Make sure the room as good air circulation
  • Keep the device away from other electronics
  • Clean and replace filters regularly

What Type of Air Purifier Should You Use?

The type of air purifier you use is just as important as where you place it. While some purifiers are used to eliminate bacteria and mold, some are only designed to eliminate dust and pollen. When choosing an air purifier, consider the type of contaminants you would like to get rid of.

Here are the most common types of air purifiers:

  • HEPA purifiers – This is one of the most popular options as it traps bacteria and mold along with pet dander, pollen, dust, and other debris. However, it does not eliminate chemicals, odor, or gasses.
  • Activated carbon – This is an air purifier that can remove chemicals and odors as well as dust and pollen.
  • Ultraviolet lamps – UV technology does not eliminate airborne particles but instead helps to kill harmful bacteria and viruses.
  • Negative ion – These purifiers don’t actually get rid of the particles, but instead, make them too heavy to remain in the air.
  • Ozone – This is a once-popular purifier that healthcare professionals now advise against using as exposure to ozone may increase the risk of lung damage and asthma attack.

The most efficient solution is to use a UV air purifier that features HEPA and activated carbon filters. These air purifiers are a multi-functioning approach to air purification by removing even more pollutants from the air.

Cleaning Your Air Purifier

It is important to remember that regularly keeping your air purifier and filters clean is an effective way of making sure it lasts longer and works to its greatest ability.

Some air purifiers have a light that will indicate when the filter is dirty, while others need to be manually checked.

Always check your air purifier’s manufacturer instructions to know how to clean your device properly.


The placement of your air purifier affects its ability to purify the air in your home. The purifier needs to be placed in an area where it can be of use; this will typically be in a living room or bedroom.

It is best to make sure that there is one to two inches of space between the purifier and any other surfaces and should not be placed right up against a wall or any furniture.

Along with deciding where you want to place the purifier, you want to consider what types of contaminants you want to eliminate in order to purchase the right type of air purifier.
