Best picks
An air purifier does not remove mould growth or fix damp. This comparison covers five models’ published airflow and room figures for airborne particles, alongside the separate need to address moisture and visible mould.
Quick answer
An air purifier does not remove mould from walls, furniture or other surfaces, and it does not fix the moisture that allows mould to grow. A suitable filter may capture some airborne particles as room air passes through it, but these manufacturer pages do not verify mould-spore removal or a health benefit. We compare five models by published CADR and room figures only. Find and address the source of damp; consider a dehumidifier where appropriate, and follow reliable advice for mould cleanup.
A room air purifier does not remove mould growing on a surface or correct damp. Do not treat filtration as mould remediation. Address the moisture source and follow appropriate cleanup guidance. A dehumidifier serves a different purpose by reducing moisture; it does not replace mould cleanup.

Best published CADR for a room
Philips publishes a 190 m³/h CADR and a 20 m² cleaning-time footnote. This supports comparing particle-cleaning specifications only; the manufacturer page does not claim mould removal or mould treatment.

Best for a larger room with a stated air-change basis
Levoit publishes a 50 m² figure at two air changes per hour and a 6–8 month filter interval. It does not claim to remove mould or correct damp; its page does not publish CADR.

Best published CADR and maximum room figure
Levoit gives a CADR of 243 m³/h and 20.8 m² at five air changes per hour. This is an airflow comparison, not a claim to remove mould or resolve the source of damp.

Best documented small-room option
Blueair recommends about 16 m² at 4.8 air changes per hour and publishes CADR figures in cfm. Its product page does not claim mould remediation.

Best for a smaller room
WINIX publishes 250 m³/h CADR and maximum room capacity of 50 m². The page does not claim mould removal; address moisture and visible growth separately.
| 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 may filter some airborne particles, but a purifier does not remove mould growth from surfaces or fix damp. The manufacturer pages in this comparison do not verify mould-spore removal.
No. It cannot remove mould growing on surfaces or solve the moisture source. A suitable filter may capture some airborne particles, but address visible mould and damp separately.
This comparison does not assess virus removal. The supplied product specifications do not establish a virus-related health outcome.
This page is about mould-related searches, and its product evidence does not establish an allergy outcome. Check specific manufacturer filtration claims and seek medical advice for personal concerns.
It does not remove mould or correct damp. At most, filtration may capture some airborne particles; deal with the moisture and mould source separately.
They need suitable placement, electricity and replacement filters. Filter prices are not available in this evidence pack, so check current running costs and follow the manufacturer’s maintenance instructions.
It cannot replace ventilation, damp control or mould cleanup, and filters need maintenance. Check the room-size basis and ongoing filter costs before buying.
These are separate jobs: a purifier filters room air, while a dehumidifier removes moisture from the air. See our air purifier and dehumidifier options and check each product’s specifications.
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.
