Can Air Purifiers Help with Asthma Triggers?

Reducing the Load

An air purifier is **not** a medical device and is not a replacement for an inhaler. However, asthma attacks are often triggered by airborne irritants: 1. **Dust Mite Droppings:** The #1 trigger in UK homes. 2. **Mould Spores:** Common in damp housing. 3. **Tobacco Smoke:** Severe irritant. A HEPA filter captures all three of these solid particles, drastically lowering the number of "events" your lungs have to deal with.

Look for Certification

When buying for asthma, look for independent certification from bodies like **ECARF** (European Centre for Allergy Research Foundation) or **Allergy UK**. This ensures the device has been tested to remove allergens effectively without producing harmful ozone.
