The UK's Most Common Indoor Allergen
House dust mites are microscopic arachnids that live in mattresses, carpets, pillows, and soft furnishings. They feed on shed human skin cells and thrive in the warm, humid conditions typical of UK bedrooms in winter. Allergy UK estimates that approximately 10 million people in the UK are allergic to dust mites. Crucially, the allergen is not the mite itself but rather its faecal particles and shed body fragments — these are typically 10-40 microns in size, well within the capture range of a True HEPA filter. An air purifier running in the bedroom captures these particles as they become airborne during movement, bedmaking, and normal activity. It will not eliminate mites from the mattress — for that you need mite-proof encasements and regular hot washing of bedding — but it dramatically reduces the concentration of airborne allergens, particularly during the night when you are sedentary and inhaling continuously for 7-8 hours.

The Complete Dust Mite Strategy
An air purifier is one part of a three-part strategy. First, encase your mattress, pillows, and duvet in mite-proof covers (available from Allergy UK). Second, wash all bedding at 60°C weekly — below 60°C, mites survive the wash. Third, run an air purifier in the bedroom 24/7. This combination addresses mites at every stage: the encasements prevent mite access to their food source; the hot wash kills mites in the bedding; the air purifier captures the allergen particles that are inevitably still present in the room. If you can only do one thing immediately, start with the air purifier in the bedroom overnight — it provides the fastest noticeable relief for morning symptoms.
