There are a lot of reasons you might want an air purifier – if you have allergies, for instance, or live with a smoker.
Air purifiers are available in a range of sizes and prices, and you should select one that’s big enough to clean the air in whatever room you expect to run it in the most.
Here are some other things to look for:
• HEPA filter – these filters trap fine particles such as dust mites, pollen, and pet danders as they clean the air.
• Prefilters or other filters – these trap bigger particles before they get to the HEPA filter, extending the life of the HEPA filter, which can be an expensive replacement.
• Noise level – if you’re going to be in the room as the air purifier runs, look for a quiet unit.
• Dirt sensor – this feature senses how much dust and dirt is in the air and adjusts the fan speed based on that reading.
Other features that are nice to have include remote control, a timer, and automatic settings. Generally, the more an air purifier costs, the more likely it is to have extra features.
