CADR (clean air delivery rate)
What is this?How many cubic metres of clean air the purifier delivers per hour on its top setting. It is the single most useful number on the box — more useful than "room size", which brands calculate generously |
433 m³/hCleans all the air in a room up to ~42 m² every 15 minutes | |
| How often it can clean all the air in a typical HDB room | ||
| Common bedroom (9–12 m²) | Every 15 min | |
| Master bedroom (12–15 m²) | Every 15 min | |
| 3-room flat living room (~20 m²) | Every 15 min | |
| 4/5-room living + dining (25–35 m²) | Every 15 min | |
Rated coverage (manufacturer)
What is this?Levoit's own figure, worked out on cleaning the room's air every 30 minutes with a 2.4 m ceiling. Fine for keeping already-clean air clean; use the CADR room guide above for haze days |
90 m² | |
Filtration
What is this?True HEPA (H13) captures 99.97% of particles at 0.3 µm — haze, dust, pollen, pet dander. Activated carbon handles smells and gases; HEPA alone does not |
3-Stage Filtration (Pre-filter, HEPA Filter, High-Efficiency Activated Carbon Filter) | |
Air quality sensor
What is this?PM2.5 means particles under 2.5 micrometres — the ones in haze and smoke that reach deep into the lungs. PM10 is coarser dust and pollen; PM1.0 is finer still. A laser sensor reads these live and drives Auto Mode. Units without a sensor run at whatever speed you set. |
PM 2.5 | |
App control (VeSync)
What is this?Control from your phone, set schedules, see live readings and remaining filter life. Works with Alexa and Google Assistant. |
Yes | |
Noise
What is this?Lowest to highest fan setting. 20–25 dB is a whisper, 30 dB is a quiet bedroom, 50 dB is normal conversation. |
28–54 dB | |
Filter life
What is this?How long one filter lasts under typical use before it should be replaced. |
12 months | |
Power draw
What is this?Maximum watts at the top fan speed. Sleep mode uses a small fraction of this. |
38 W≈ $8.21/month at full speed, 24/7 | |
Dimensions (W × D × H)
What is this?Cylinder models need about 30 cm of clearance all round because they draw air in from every side. Panel models can sit closer to a wall. |
27.4 x 27.4 x 52 cm | |
| Weight | 5.0 kg | |
Child / display lock
What is this?Locks the touch panel so curious hands or paws cannot change the settings. |
Yes | |
Warranty (Singapore)
What is this?Local warranty serviced in Singapore (Dasher service centre, 4 Pandan Crescent). |
2 years | |
Room guide: “Every 15 min” means the purifier can clean the whole room’s air every 15 minutes at top speed — fast enough to clear haze or cooking smoke. “Every 30 min” is fine for keeping already-clean air clean. Based on a 2.6 m ceiling. CADR figures are manufacturer-stated in m³/h.
