An air purifier can help improve the quality of the indoor air in your home, but its location can seriously affect its effectiveness in cleaning the surrounding air. So where should you put your air purifier?

Where in your home to put an air purifier

There is no single answer to the best location for an air purifier. It depends on many factors, including the details of your air purifier, your home, and where you spend most of your time. Ideally, you should start thinking about the location of your air purifier as you shop for it. This is because the number of air purifiers you are buying and the size of the area they can clean efficiently will play a big role in where you will place your air purifier.

Ideally, you have air purifiers for every room where you spend a significant amount of time in your home. So, it only remains to think about where to place those air purifiers in their respective rooms. But if you only have one air purifier, it’s best to place it in the room where you spend most of your time. For most people, that’s the bedroom, as we spend nearly a third of our lives sleeping. But if you work from home, you can also put it in your home office, since you would be spending a lot of time there.

Air purifiers can also be moved between locations as the day progresses. So an air purifier can be in your bedroom while you sleep and in your home office or living space during the day. However, remember that some air purifiers can be heavy or difficult to move. So if you think you’ll be moving your air purifier often, it’s a good idea to invest in one with wheels and handles.

Once you have chosen the room where your air purifier will go, you need to decide exactly where in the room to place it. The best location is usually in the center of the room, as it allows the air purifier to distribute filtered air in all directions for the most efficient operation. But due to the length of cables and the way we tend to arrange our furniture, that’s rarely possible.

So the next best location is to place the air purifier in areas with the best airflow, as that would help get clean air everywhere quickly. For example, areas around a door or near windows are often the best for airflow. On the other hand, corners have the worst airflow, so avoid placing your air purifier in a corner.

You can also place it next to a source of contamination, such as mold buildup, pet living quarters, or vents, to efficiently and quickly trap any contaminants before they spread. Additionally, it is recommended to place the air purifier three to five feet above the ground to take advantage of both horizontal and vertical air movement.

Lastly, make sure there is enough space around the air purifier so that its inlet and outlet are not obstructed.

Can you run it 24/7?

Now that you’ve set up your air purifier, you may be wondering if you should run it permanently or if a few hours is okay.

It is highly recommended that you leave your air purifier on continuously for the best experience. This is because the air in your home is constantly changing. Whether the air outside is bringing in pollutants or something inside the house is releasing pollutants, it doesn’t take long for filtered air to become polluted again. So keeping your air purifier running all the time is ideal, and there’s nothing wrong with doing that because it’s usually designed to run 24/7.

But if you don’t want to or can’t run it continuously, there are times when you can turn off an air purifier. For example, if you and your family are going out for several hours or days and no one will be home, you can turn it off while you leave and turn it on when you return. Plus, many air purifiers these days have smart features built in, so you can also schedule it to turn on an hour before you’re due back to make sure you get filtered air.

Also, if you have multiple air purifiers in your home, you can turn all of them off except the ones in the bedrooms when you sleep.

Some people run their air purifiers intermittently due to power usage issues. But unlike many other appliances in our homes, air purifiers consume relatively little energy. For example, on average, an air purifier uses about 50W of power, which means it will use at most 1.25kW of power in 24 hours. So even if you run it for an entire year 24/7, you’ll end up with power consumption of just 465kW, or $91 worth of power billed at a rate of 20 cents per kWh.
