Air Quality (Allergies + Damp)
The biggest win is matching the purifier to the room size — not buying the fanciest model.
Start here
- Check your room size (m²) before buying.
- Choose HEPA + carbon if odours bother you.
- Put it where the air flows (not hidden in a corner).
- Replace filters on schedule — it matters more than “extras”.
If damp/mould is the issue
A purifier helps particles, but damp often needs dehumidifying + ventilation.
Avoid
- Overpaying for “smart” features you’ll never use.
- Units that are too loud for bedrooms (you’ll stop using them).
- Buying small units for big rooms.
