Investing in an air purifier is a great way to improve the overall air quality of your home. But what many people don’t realize is that even the best air purifiers are only as good as their placement with the home.

Air purifier location does matter, so use this guide to learn about the best place to put your air purifier for maximum benefits. We’ve provided you with tips on where to place an air purifier in the house, safety precautions for setting up the device, and more.

Whether you’re looking for air purifiers to relieve allergies, combat asthma symptoms, or just to give your home’s air quality a boost, the key to better air quality is to invest in multiple purifiers.

While air purifiers can be extremely powerful, they are unable to work through walls. If you have a purifier in the master bedroom, that means only the air circulating within that room will go through the purification process.

That’s why it’s recommended to invest in an air purifier for some or all of these rooms in the home:

  • In the Kitchen
    A kitchen air purifier is great for removing common odors from cooking and food waste. In terms of placement, the best place to put an air purifier in the kitchen is near the trash can or right next to the kitchen table.
  • At the Front Door
    One of the biggest access points for airborne contaminants to enter the home is the front door. That’s why many homeowners place an air purifier in the foyer.
  • In the Living Room
    The living room is where you do lots of your living, so why not freshen up the air in here with an air purifier? This is an excellent place for a purifier, and placing the machine near the couch is a solid option.
  • In the Bathroom
    Bathrooms are one of the smelliest rooms of the house, so it just makes sense to put an air purifier in here. You can either get a small countertop purifier and place it next to the sink or use a full-sized purifier next to the toilet.
  • In the Bedroom
    Using an air purifier in the bedroom is a great way to improve sleep quality. Not only will you breathe easier, but the gentle lull of the machine is perfect white noise while you sleep.
  • In Garages/Basements
    Garages and basements are prone to high moisture levels, which means higher levels of contaminants in the air. If you decide to invest in an air purifier for your garage or basement, just make sure that it’s rated to handle large square footage areas.

If your budget only allows for a single unit or you’re only interested in purifying a small space, one air purifier should do the trick.

How to Find the Best Place to Put an Air Purifier

Where to Place an Air Purifier
  1. .Place it where the worst air pollutants are
    Your main goal for buying an air purifier is probably to improve your home’s air quality, so focus on improving the area of your home that needs the most help. If you know that a certain room or space is prone to mold, dust, smoke, or other pollutants, the first placement step is to focus on that area.
  2. .Put it in places with the highest airflow
    Air purifier performance is greatly affected by the surrounding airflow. The higher the airflow, the better the purifier will be able to draw in air in order to clean it. That’s why it’s best to place your purifier in areas with high airflow, like near a window or close to a doorway.
  3. .Don’t place it in a corner or with low airflow
    This next rule goes along with the previous one. By using an air purifier in areas with very little airflow, like the corner of a room, you won’t get to experience all the benefits.
  4. .Don’t place it behind obstacles
    Do your best to leave about 3 feet of space surrounding the air purifier from all angles. That means you should avoid putting furniture, books, appliances, and ANYTHING too close to the purifier.
  5. .Place it 3 to 5 feet off the ground
    By placing the purifier off the ground, the machine will be able to capture air moving in all directions, including hot air that rises.
  6. .Keep it away from electronics
    Electronic devices like TVs, stereos, and microwaves can interfere with a purifier’s function. This is especially true for modern-day purifiers that use advanced technology to operate. It’s best to keep all electronics at least 5 feet away.
  7. .Avoid high humidity areas
    Air containing lots of moisture is heavier than dry air, which means an air purifier will have to work extra hard to purify humid air. On top of that, humidity can have a negative effect on the purifier’s filtration system.

People Also Ask (FAQ)

Which way should the air purifier face?

It’s best for the purifier to face towards the middle of the room. As long as the machine isn’t too close to the walls and there are no obstacles in its way, it should be able to draw in the surrounding air and expel it back into the room.

Can I put my air purifier on a table?

Yes, some air purifiers are designed to sit conveniently on a table or countertop. It depends on the model, though, so if you want to put your purifier on a table, look for a tabletop machine.

Should I run an air purifier all the time?

Yes, it’s generally recommended to leave a purifier on continuously. Most air purifiers are designed with an “Auto Mode,” so they’ll turn on and off on their own based on the room’s current air quality.

When should I use the low and high settings?

Whether or not you use low or high settings is based on the quality of the air. For highly polluted air that contains lots of pollen, dust, smoke, or whatever it may be, it’s best to use the purifier’s high setting.

Will a dehumidifier improve air quality?

When comparing air purifiers vs. dehumidifiers, these two machines have something in common; both will improve air quality. However, a dehumidifier’s primary focus is to remove moisture from the air, so if a boost in air quality is what you’re looking for, an air purifier is the better choice.

How much area does an air purifier cover?

This depends on the specific model – all air purifiers have different specs for coverage areas. Before buying your purifier, always consider the square footage of the room you’ll be using it in.

Conclusion

Hopefully, this guide on where to place air purifiers has helped you find the perfect place for your Dyson, Holmes, or Honeywell air purifier. The main thing to remember when deciding on the optimal location is to remove all obstacles, choose a spot with maximum airflow, and avoid placing the machine too close to walls.
