Asthma is aggravated by airborne triggers: PM2.5 from traffic, dust, pollen and mould spores. Reducing the particle load in the rooms you use most can mean fewer flare-ups — and London's traffic PM2.5 makes that especially worth doing.
How an air purifier helps with asthma
- PM2.5 & traffic pollution: MERV-13 airflow keeps fine-particle counts low, which is the trigger most tied to London air.
- Dust & pollen: continuous filtration removes triggers before they settle into bedding and carpets.
- Overnight: a quiet kit on low protects you through the hours you breathe most.

Can an air purifier help my asthma?
It can reduce airborne triggers like PM2.5, dust and pollen, which may lessen symptoms — but it complements, not replaces, medical treatment.
HEPA or MERV-13 for asthma?
MERV-13 captures the fine particles that trigger asthma while moving more air, so it clears the room faster. For homes that usually matters more than HEPA's marginal edge.
