  • You should check the stats before buying an air purifier, paying close attention to its CFM and CADR ratings.

Are There Multi-room Air Purifiers?

Simply put, most air purifiers can purify more than one room simultaneously, but the exact amount will be set by the square footage of the rooms in question and the power of the purifier itself. Read this article to know troubleshooting tips for your air purifier when it stops working.

Do I Need an Air Purifier in Every Room?

You do not need an air purifier in every single room, though you may need more than one throughout your home depending on a variety of factors including home size, air purification power, and just how unhealthy your home’s air is.

How to Purify Multiple Rooms at Once

Here are some tips to help you purify the air throughout your home without having to buy an air purifier for each and every room.

Run it Continuously

You can run your air purifier continuously, providing that it is on its lowest setting. Running your purifier all of the time can help treat several rooms at once, particularly if these rooms are connected in some way. Be wary when it comes to continuously operating an air purifier at its highest setting, as this can eventually wear down the unit.

Check the Stats

There are several commonly found stats that you will run into while shopping for an air purifier. These numbers could let you know how the purifier will do when it comes to treating multiple rooms at once. Look for the cubic feet per minute number, otherwise known as the CFM, and the clean air delivery rate, otherwise known as the CADR. These metrics illustrate just how powerful the unit is and how quickly it can purify the air.

Move the Purifier Around

If you are not going to be running your purifier continuously in a single room, feel free to move it around the home as needed. You can run it in the bedroom before sleeping, for instance, and then move it to the living room as you work remotely or take care of the kids. Air purifiers tend to be rather light and easy to transport. Also you can use a water air purifier, and this article will show you how.

F.A.Q.

What are air purifiers supposed to filter out and do they actually do it?

Air purifiers are supposed to filter out anything out of the ordinary that is floating around in the air. This can include allergens, pet dander, dust, smoke, virus particles, and bacteria, among other items. As to their efficacy, it depends on the make and model of the air purifier.


Can air purifiers filter the outdoor air that enters your home?

Air purifiers can filter the outdoor air that enters your home, but you should exercise caution when allowing outdoor air inside your house. This is because an air purifier can only filter so much air at once.


How to calculate if you need additional air purifiers?

Let’s do some math. If an air purifier is rated to treat 500 square feet, and you have a 2,000 square foot home, you will need four air purifiers.



STAT: In the North American definition, “true HEPA” means that a filter removes at least 99.97% of airborne particles of a 0.3-micron diameter in a single pass. (source)
