SwitchBot Air Purifier — Matter-enabled HEPA air purifier with reasonable noise/CADR balance
Owner’s hands-on review ★★★★☆

Great, but Home Assistant Exposure is lacking

I have allergy problems, and thus want air purifiers I can change the fan speed of based on things like outdoor air quality, rather than waiting for indoor air quality to go below the threshold to bump up the level.

I have two, and while I haven’t found an air purifier I like more, home assistant integration is a little frustrating (Changing the fan speed requires more clicks than I want).

I first integrated with home assistant and when I added it to the Switchbot app, it unpaired from home assistant, which was also annoying.

Quick verdict

A solid mid-range HEPA purifier that exposes to Home Assistant locally over Matter (through a SwitchBot Hub 2 or 3). Matter currently covers on/off; fan-speed control comes via the local SwitchBot Bluetooth integration, so it is local-capable but a little clunky to drive.

Standout: Matter-enabled HEPA air purifier with reasonable noise/CADR balance.

Why it stands out

  • Real HEPA filter at a reasonable price for the noise level
  • Matter support means it can be added to Home Assistant or HomeKit without the SwitchBot cloud
  • Compact for the CADR rating; works well in a single room

Reasons to hesitate

  • Out of the box, control still routes through the SwitchBot cloud unless you set up Matter
  • Filter replacements are an ongoing cost
  • HA integration via HACS is community-maintained, not first-party

Best for

  • Single-room air purification for households already running Matter
  • People who want quieter operation than the budget alternatives

Avoid if

  • You want a fully local-control air purifier out of the box without Matter setup
  • You need whole-home coverage (look at AirGradient + a larger HEPA)

Privacy and local-control notes

Pairs to SwitchBot account by default; some control is possible via local BLE bridge but cloud is the primary path. Matter support is the cleanest route to local control.

Home Assistant support: supported · integration path: Matter (via SwitchBot Hub 2/3) plus SwitchBot Bluetooth (HACS) for fan speed.

Buying reality check

Price notes: Mid-tier on price; filter replacement cost is the long-term variable.
