This guide will tell you about the kinds of indoor pollutants that a purifier can help combat, along with the specific types of air purifiers.
Tip: When choosing an air purifier, the size of the room is one of the most important aspects to consider.

Placement, Performance and Features
Make sure the purifier is suitable for the size room you’re looking to protect, and look for a high clean air delivery rate – the cubic feet of air a purifier cleans per minute.
Placement
- Avoid placing a purifier in a room that’s too large for it to fully cover.
- Some devices, like UV purifiers, are installed directly into your HVAC system.
- You may need a purifier for each room you spend time in.
- Casters and handles make it easier to move portable units around.
Performance
- Improve the effectiveness of your air purifier and extend filter life by using pre-filters that trap large particles before air gets to the main filter.
- To ensure quality, look for purifiers that have been approved by the Underwriters Laboratory.
- Filters with larger surface areas are more effective than smaller ones.
- The clean air delivery rate (CADR) indicates how many cubic feet of air a purifier cleans per minute.
- The more air changes per hour a machine provides, the higher the quality of air it creates.
Features
- Multispeed fan: Allows you to increase or decrease the speed to help provide the proper number of air changes per hour in different-sized rooms.
- Quiet operation: Operates quietly so you can sleep soundly without sacrificing air quality.
- Automatic timer: Set your purifier to turn on and off automatically.
- Filter change indicator light: Lets you know when it’s time to change the filter.
