If you don’t want to move your air purifier around all the time, place it in the room where you spend the most time each day.

You eat a well-balanced diet and exercise regularly. But there's another component of health to pay attention to: the air you breathe. If the air around you is full of contaminants and allergens, it could make you sick or cause respiratory problems. Fortunately, there are dozens of air purifiers on the market. Here's a quick look at what you need to know in order to choose the air purifier that's right for your home.

Considerations when choosing air purifiers

Air purifiers come in two types: portable and whole-home units. A whole-home unit is useful if you want to make sure all the air in your home is filtered all the time. But for most people, a portable air purifier is a better fit.

Portable air purifiers filter the air in a single room, and they're light enough that you can move them around as needed. These units come in different sizes, so think about the largest room you plan on using your air purifier in before choosing a size.

Features

There are several important factors to consider when choosing an air purifier.

Size

Look at the capacity of the air purifier to see how much air it can filter. This is often listed in square footage. Make sure you choose a unit that is large enough for the largest room you're going to use it in.

ACH/CFM rating

The air change per hour (ACH) and cubic feet per minute (CFM) ratings indicate how many times the air purifier will filter the air in a room. The more times the air is filtered, the cleaner it will be.

Filter type

Some air purifiers can filter smaller particles from the air than others. If allergens are a problem for you, an air purifier with a HEPA filter may be best.

Replacement filters

All air purifiers will need their filters replaced periodically. This is an ongoing expense, so it's important to pay attention to how often the filters on your unit need replacing and how much the replacement filters cost.

Speed settings

Some air purifiers come with multiple speed settings that enable you to choose how quickly the air is filtered and, consequently, how loudly the machine runs.

Timer

Your air purifier may have a timer setting, so you can determine when and for how long you would like it to run. This way, you don't always have to remember to turn the unit on and off.

FAQ

Q. What do air purifiers filter out of the air?

A. Air purifiers are typically designed to filter out dust, mold spores, pollen, pet dander, and smoke from the air so that you can breathe easier.

Q. What is a HEPA filter?

A. HEPA stands for high-efficiency particulate air. These filters are able to trap particles as small as 0.3 microns, and they're ideal for those with allergies who are not helped by a standard air purifier.
