Best picks
The Levoit Vital 100S and WINIX ZERO Compact publish CADR figures in m³/h. We compare five models by manufacturer data, with room-size assumptions and missing costs made clear.
Quick answer
For airborne dust, compare a published particle CADR with the room size and air-change rate behind the manufacturer’s figure. The Levoit Vital 100S publishes 243 m³/h; WINIX ZERO Compact publishes 250 m³/h. Philips AC0820/10 publishes 190 m³/h, while Blueair gives its dust CADR in cfm. These specifications do not mean a purifier will remove settled dust from surfaces. Filter prices are absent from the source pack, so annual filter cost is shown as —.
Compare the manufacturer’s CADR with the room-size and air-change basis. A purifier filters airborne particles; it does not remove settled dust, replace routine cleaning or correct damp.

Best published CADR and compact-room figure
Philips publishes a 190 m³/h CADR. Its page distinguishes a 20 m² cleaning-time footnote from a 48–49 m² maximum room-size claim, so use the lower figure when comparing cleaning assumptions.

Best for a larger room with a stated air-change basis
Levoit gives 50 m² at two air changes per hour (or 100 m² at one) and Sleep Mode at 22 dB. Its UK page does not publish a CADR, so check airflow against your room before choosing.

Best for a compact room
Levoit publishes CADR of 243 m³/h and 20.8 m² at five air changes per hour. The filter interval is 8–12 months; filter cost is not in the source pack.

Best for a smaller room with particle CADR figures
Blueair recommends about 16 m² at 4.8 air changes per hour and publishes CADR in cfm rather than m³/h: 123 cfm for dust. Sound ranges from 24 to 49 dB.

Best published CADR for a larger room
WINIX publishes CADR of 250 m³/h and a maximum room capacity of 50 m². The manufacturer does not state the air-change basis for that room figure.
| Model | CADR | Room figure and basis | Noise figure | Filter interval | Annual filter cost |
|---|---|---|---|---|---|
| Philips AC0820/10 | 190 m³/h | 20 m² cleaning-time footnote; 48–49 m² maximum claim | 19 dB(A) sleep; 49 dB(A) max | 12 months | — |
| Levoit Core 300S | — | 50 m² at 2 ACH; 100 m² at 1 ACH | 22 dB sleep | 6–8 months | — |
| Levoit Vital 100S | 243 m³/h | 20.8 m² at 5 ACH | — | 8–12 months | — |
| Blueair Blue Pure 511 | 123 cfm dust CADR | about 16 m² at 4.8 ACH | 24–49 dB | 6 months | — |
| WINIX ZERO Compact | 250 m³/h | 50 m² maximum; ACH basis not stated | 26.5–53.7 dB | 12 months | — |

Common questions
They can filter airborne particles as room air passes through them. The figures here describe manufacturer-rated airflow or room assumptions; they do not mean settled dust on furniture or floors will disappear.
The source pages in this list do not provide pet-safety assessments. Follow the manufacturer’s placement and operating instructions, and keep pets away from the appliance and its cable.
These product specifications do not establish an asthma outcome. Speak with a qualified healthcare professional for personal medical advice.
A model with suitable particle CADR for the room can filter airborne particles. Compare the CADR and air-change basis; an air purifier does not replace dusting or vacuuming.
It cannot stop dust from being created or settling. Its role is to draw room air through a filter; match the published airflow to your room and continue normal cleaning.
This page compares household models, not car purifiers. Vehicle size, power and ventilation differ, so these room-air specifications do not answer that question.
They may filter some airborne particles while operating, but they do not remove dust already settled on surfaces. Room size and airflow affect the comparison.
They can capture airborne particles that pass through their filters. Results depend on the model, room and use; none of these specifications promises a dust-free home.
We compared manufacturer specifications and UK Amazon catalogue records supplied for this brief. Gearjury has not physically tested these air purifiers. Suitability labels describe the published figures and do not imply a health result.

Philips AC0820/10 leads with a 19 dB(A) sleep mode in manufacturer data. Levoit, Blueair and Winix cover other bedroom needs, from small rooms to larger spaces.
Philips AC0820/10 has the lowest published sleep-mode noise in this shortlist. Levoit, Blueair and Winix offer alternatives for different room sizes and features.
