Spring is here, and if you're thinking about your allergies, you may want to consider using an air purifier. According to the EPA, an air purifier with a HEPA (high-efficiency particulate air) filter can remove up to 99.7% of airborne particles with a size of 0.3 microns, which includes dust and pollen. It can also help keep your home free from smoke particulate, if you live in parts of the world that will experience an upcoming wildfire season.

Before you start using an air purifier, you'll want to make sure you set it up correctly. You wouldn't want to spend hundreds of dollars on a product that's less effective than it could be. Here's where to put your air purifier to ensure optimal performance. For more, take a look at our guide on how to clean your air purifier so it runs optimally, and these expert-approved tips to protect yourself from wildfire smoke

The best place to install your air purifier

Using an air purifier isn't quite as simple as plugging it in and turning it on. Fortunately, it isn't that complicated, either. There are just a few things you want to do when you first set yours up to give it the best possible chance of cleaning your air. 

  • To begin, you want to make sure you have between 18 and 24 inches of room around the unit for it to operate correctly, according to the Montana Department of Public Health and Human Services (PDF). 
  • You should also keep the doors and windows closed in the room where the air purifier is working so more smoke and allergens aren't coming in from other rooms -- or from the outdoors. 
  • Whirlpool, a manufacturer of air purifiers, suggests picking a "firm, level and flat" spot to install its units, as well as facing the front of the air purifier toward the center (or most open section) of the room. Lastly, the company recommends putting a mat underneath an air purifier if it's in a room with light carpet, to avoid stains.

Another thing to keep in mind when it comes to air purifiers

It's important to note that other factors can determine how your air purifier operates, such as regular maintenance and cleaning. An air purifier might be set up correctly in a room, but if you aren't cleaning it regularly (once every few months or so), its performance could suffer. You also want to make sure you have the correct size air purifier to tackle the room (or rooms) where you plan to use it the most. If it doesn't have the right capacity for the space -- if it's too big or too small -- you might also run into issues.
