Dyson Purifier Hot+Cool HP09
✓ Pros
- Three functions in one: heater, fan and HEPA H13 air purifier
- Real-time particulate and VOC sensors display air quality continuously
- Fully sealed system — air only exits through the filter, not around it
- Projects purified air across the whole room (not just near the unit)
- App control and scheduling — runs intelligently without intervention
✗ Cons
- £600+ for a fan/heater/purifier combination
- Heater function raises electricity costs if used frequently
- Filter replacement costs £60-70 per year — budget for this
Levoit Core 400S Smart Air Purifier
✓ Pros
- True HEPA H13 captures 99.97% of particles 0.3 microns and above
- CADR 260m³/h — independently tested, not just manufacturer claims
- PM2.5 laser sensor triggers auto mode when air quality drops
- VeSync app provides air quality history and scheduling
- Relatively low filter running costs — ~£25-35/year vs Dyson's £70+
✗ Cons
- Purification only — no heating or cooling like Dyson HP09
- Real-world coverage is 40m² — ignore the 'large room' marketing for anything bigger
- Auto mode fan noise at maximum (52dB) is noticeable
