Smart Home · Smart Air Purifiers (App-Connected)
Do smart purifiers actually need WiFi to work?
Reviewer consensus
No. Every model in this roundup runs as a standard purifier with onboard buttons if you skip pairing. The app unlocks scheduling, voice-assistant integration, filter-life tracking, and remote air-quality monitoring, but reviewers on r/dyson and r/AirPurifiers frequently note that the apps themselves can be flaky and that core purification is unaffected if you never connect.
