IKEA's side table that doubles as an air purifier — round top, about 21–22" tall and 21" in diameter, with a real air purifier built into the base. This color isn't sold anymore.
Lift the top off to access the filter. Runs on 5 fan speeds or auto mode, which reads the room's air quality (PM2.5) and adjusts itself. Filters out about 99.5% of dust, pollen, and other fine particles. Comes with the particle filter; pairs with the IKEA Home smart app if you have a DIRIGERA hub, but works fine as a standalone unit without one. Retails for $199.99 new. Pick up in Somerville.
