Can get loud
If you suffer from allergies, asthma, or are worried about airborne transmission of COVID-19, a high-quality air purifier can help you breathe a little easier. Suitable for rooms up to 512 square feet, LG s $1,299 LG PuriCare 360 packs two large 360-degree filters, both of which feature a True HEPA layer that promises to trap 99.97% of dust particles as small as 0.3 microns, and an active carbon deodorizing layer that captures foul smells and reduces harmful gases in the air. It also features Wi-Fi, so you can control it with your phone or voice in addition to the included remote, and LG s companion app lets you remotely monitor your home s air quality and create a weekly cleaning schedule. In testing, the PuriCare 360 cleared the air faster than the $799.99 Dyson Pure Humidify+Cool, so while it s definitely one of the pricier smart air purifiers you can buy, it s also one of the more effective.
