Today only, you can save up to 33 percent on six models of brand air purifiers and humidifiers that range from $20-$120. The cheapest—a humidifier by the name of MistAire Studio—is best for smaller rooms. It has a .7-liter tank and runs for 10 hours.

The PureZone Elite—the most expensive—is a four-stage air purifier that runs the air through an active carbon pre-filter, True HEPA filter, a UV-C light, and an ionizer. The device also uses a smart air monitor that gauges air quality in real time and then adjusts its fan speed to clean the air faster. The purifier has an indicator that lets you know when to change the two filters. $120.
