Mould & Spores

Mould releases microscopic spores (2-10 microns) that trigger allergies and asthma. While a purifier cannot kill mould on walls, it captures airborne spores to stop them spreading and landing elsewhere.

info

Health DisclaimerAir purifiers capture airborne spores but cannot remove mould growing on surfaces. You must treat the damp source first.

Expert Guides on Mould & Spores

Do Air Purifiers Help with Damp and Mould?

Do Air Purifiers Help with Damp and Mould?

Mould is a major issue in UK homes. Can an air purifier fix it, or do you need a dehumidifier? We explain the difference.

Common Questions

?Do air purifiers kill mould?

No. They trap airborne spores preventing them from colonizing other areas, but they do not remove existing mould from walls.

?What filter do I need?

A True HEPA (H13) filter is essential. Avoid "HEPA-type" or lower grades which may let spores pass through.

?Will it stop mould returning?

It reduces the spread, but if humidity remains >60%, mould will likely return. Fix leaks and ventilation first.

?Is UV light necessary?

UV-C can neutralize spores in the unit, but a high-airflow HEPA filter is far more proven and effective for residential rooms.
