The Dyson Purifier Cool Formaldehyde TP09 is engineered to create a cleaner, healthier indoor environment. Featuring advanced solid-state formaldehyde sensing, it continuously detects and destroys formaldehyde gas—a common indoor pollutant emitted by furniture and household products. Its fully-sealed HEPA H13 filtration system captures 99.95% of ultrafine particles, including dust, allergens, and VOCs. Designed with Air Multiplier technology, it circulates purified air throughout the entire room while operating 20% quieter than previous models. The elegant gold finish makes it a sophisticated addition to any home or office space.
