Our take
The Core 400S pairs a True HEPA H13 filter with a built-in laser dust sensor and the VeSync app, covering rooms up to ~1,900 sq ft with a single air change per hour. It's the go-to mid-range pick because it delivers genuinely strong CADR and a real PM2.5 readout at a price well under premium rivals. The main catch is that VeSync is an account-required ecosystem and replacement filters are proprietary.
What we like
- High CADR for large rooms with a real laser PM2.5 sensor and auto mode
- Quiet 24 dB sleep mode and accurate app air-quality display
- Strong value versus similarly capable competitors
- Works with Alexa and Google Assistant
What to keep in mind
- Requires a VeSync account and cloud connection for full smart features
- Proprietary filters add ~$50 every 6-12 months
- Bulky cylindrical footprint takes up floor space
