Understanding where to position your portable air purifier is a vital step in achieving the desired results. In this guide, we’ll explore the strategic placements that can maximize the impact of your air purifier, helping you breathe easier and enjoy a healthier atmosphere.

How to Use an Air Purifier

If you just bought an air purifier or are considering getting one, you may be wondering how to use it. The answer is simple: you place it in a room, turn it on, and let it work. Seriously—that’s all you have to do. This means the real difficulty is deciding where to place it in your home.

Factors to Consider Before Installing an Air Purifier

Room Size

Larger rooms are more difficult to purify. Purifiers are rated by the size of the room they can handle. In general, a larger purifier can handle a larger room.

However, there is something to be said for using multiple smaller units. If your home or room is broken up by walls or other obstacles, multiple smaller units can do a better job cleaning the air than one larger unit.

Air Quality Concerns

If you’re trying to reduce the effects of a particular contaminant, pay attention to its source. Contaminants are most concentrated near their source, and your purifier will work best if placed in that area. If it’s placed farther away, the contaminants will disperse throughout the room.

If you’re worried about potential allergens from a furry friend, you can place the air purifier near your pet’s bed. The unit will trap the allergens before they ever leave the source.


If you want to get the most out of your air purifier, make sure it has adequate airflow around it. Purifiers work by pushing air through a filter, and they need a clear path to do this efficiently. When choosing where to put your air purifier, try to avoid corners or any areas where furniture or other obstructions could reduce airflow.

Some areas may receive additional airflow from your air conditioning unit or heating system. This is another thing to consider when installing an air purifier.

Best Place to Install an Air Purifier

While you can put an air purifier in any room, there are a few places people tend to choose over others. 


You spend a significant portion of your day sleeping. During that time, you’re impacted by the quality of the air in your bedroom. This can impact the quality of your sleep, which impacts your energy levels and overall wellness.

With this in mind, you may wonder where in your bedroom to put an air purifier. One of the top choices may be near the door so the unit catches any contaminants before they have a chance to make it into the room. However, don’t put it so close that it will hit the door or where airflow will be disrupted.

Living Room

The living room is one of the most common places to put an air purifier. It’s the room where people gather and paths cross. It’s also the room where contaminants multiply.

That’s why placing an air purifier in your living room is a great choice. Just be sure to place it somewhere discreet so it doesn’t disrupt the organization and aesthetics of your living space.


Your kitchen is a common source of odors and CO2 particles. Placing an air purifier in your kitchen is a great way to eliminate these unpleasant odors and potentially harmful particles.

When placing an air purifier in the kitchen, choose a safe area for it. Don’t put it too close to the oven or in a commonly used pathway.

Additional Tips

When using your air purifier, there are some other factors to consider. These helpful tips and tricks will help you get the most out of your air purifier.

Placements to Avoid

There are a few things you should avoid when considering where to place your air purifier. The most important is to not place it directly against another appliance or object. You shouldn’t put it right up against a wall or the back of your sofa. With this in mind, room corners are the worst places to put them. Instead, aim for a place where the air purifier will have room to breathe and do its job.

Maintenance and Filter Replacement

Air purifiers don’t operate without some interruptions. Their filters must be replaced regularly. If they’re not, the filter will get so dirty that it will restrict airflow and reduce the unit’s effectiveness. Follow the unit’s manufacturer’s recommendations for proper unit maintenance.

Airflow Tips

Improving the airflow in your air purifier will help it work better. Keep the unit away from obstructions, including walls. Placing it roughly six inches from the wall can help boost airflow.

Another way to increase airflow is to elevate the purifier about three to five feet. You can do this by setting it on top of a table. If you have minimal table space, consider a wall-mounted option.
