Mould spores are 2–20 microns — squarely in MERV-13's capture range. In London's older, damp-prone housing stock (Victorian conversions, ground-floor flats) a purifier reduces the airborne spore load while you tackle the underlying damp.
How an air purifier helps with mould
- Spore capture: MERV-13 traps the 2–20 micron spores that trigger symptoms and spread mould.
- High-risk rooms: bathrooms, kitchens and bedrooms on cold external walls — run the purifier there.
- Companion, not cure: a purifier lowers airborne spores; you still need to fix the moisture source.

Can an air purifier remove mould?
It captures airborne mould spores, reducing spread and symptoms — but it won't remove mould already growing on surfaces or fix the damp causing it.
Why is MERV-13 suitable for mould?
Mould spores are 2–20 microns, well within MERV-13's capture range, and high airflow clears them from the room quickly.
