What is air quality, and why does it matter?
The air we breathe indoors is rarely as clean as we think. Ultra-fine particulates, gases, pollen, and mould spores accumulate — and modern insulation seals them in.
This page explains what air quality really means, which pollutants matter most, and how HEPA filters actually work.
What's in the air?
PM2.5 and PM10 are particulate matter — the finest dust. VOCs are volatile organic compounds from paints, cleaners, and furniture. CO₂ builds up in closed rooms and reduces focus. Pollen and mould spores are biological allergens.
Health impact
Long-term exposure to PM2.5 is linked to cardiovascular disease, asthma, and reduced lung function. Children, the elderly, and people with asthma or allergies feel the effects first.
How HEPA and HyperHEPA work
HEPA filters catch particles through a combination of three physical mechanisms: impaction, interception, and diffusion. HyperHEPA goes further — a filter density that catches particles down to 0.003 microns, a hundred times smaller than standard HEPA.
The Iceland context
Iceland has some of the cleanest outdoor air on Earth — but volcanic ash, geothermal fumes, tightly insulated homes, and pollen seasons mean indoor air can still be worse than outdoor. On good days the difference is small. On bad days, it's big.
