The SwitchBot Air Purifier Table comes in a white or natural wood finish and has a cylindrical base measuring 17 by 9.8 inches (HW). It pulls in air through the removable grille on the back of the unit and expels purified air through the grille on the top. The 3-by-11.3-by-16.6-inch (HWD) simulated-wood-grain oval tabletop sits above the air outlet and is connected to the purifier via a data cable. The tabletop has a maximum load-bearing capacity of 11 pounds and includes a Qi1 wireless charging station that delivers 15 watts to Android phones and 7.5 watts to Apple phones. It ships with a screwdriver and screws for securing the tabletop to the purifier, an AC power adapter, and a user manual.
The SwitchBot is designed for rooms up to 360 square feet and uses a 360-degree, three-stage filtration system. The cylindrical filter assembly sits behind the removable magnetic panel on the lower half of the base. The filter has an outer layer of gauze material that captures pollutants such as dust, hair, and pet dander, and can be removed for washing or vacuuming. The gauze is wrapped around a HEPA filter that captures 99.97% of microscopic PM2.5 (particulate matter with a diameter of 2.5 micrometers or less), including bacteria, mold, pollen, and smoke. Finally, a carbon filter is used to eliminate odors such as ammonia, cigarette smoke, hydrogen sulfide, and other pollutants that emit unpleasant smells. The filter assembly is rated to last 6 to 12 months, depending on usage, and replacements are reasonably priced at $39.99. That’s much more affordable than the Blueair Blue Signature filters, which cost $99.99, though that model covers about twice the room size.

An LED dome attached to the bottom portion of the tabletop acts as a night light with 10 available colors. It also serves as a PM2.5 status indicator that glows blue when the air quality is very good (0-50 ug/m3), green when it is good (51-100 ug/m3), orange when it is moderate (101-150 ug/m3), or red when it is bad (greater than 150 ug/m3). The purifier’s air quality sensor only measures PM2.5 contaminants in the air, while the Blueair Blue Signature adds PM1 (particulate matter with a diameter smaller than 1 micron) and PM10 (particulate matter with a diameter of 10 micrometers or less) readings. Missing is a digital display that shows you the actual PM2.5 measurement, a feature of many other purifiers such as the Morento Smart Air Purifier HY4866-WF, the AiDot WELOV Matter P200 Pro, and the Blueair Blue Signature.
The onboard control panel on the SwitchBot purifier’s front edge includes buttons for Power, Mode (Sleep, Auto, Pet), Fan Speed (1-3), Child Lock, and Timer. LED indicators illuminate to let you know when the purifier is connected to Wi-Fi, when the child lock is enabled, when the filter needs to be changed, and the current fan speed level, mode, and timer setting (2, 4, or 6 hours).
In Sleep mode, the purifier runs at a low fan speed to reduce noise, while Auto mode adjusts the fan speed based on air quality. Pet mode runs at high speed to help remove pet hair, dander, and odor. Near the top of the purifier, there’s an aroma pad box. You can slide the box out and douse the pad with essential oils to add fragrance to purified air. Finally, the power port is located around back near the bottom.
