General description vhbw offers a high-quality, precision-fit HEPA filter designed specifically for Bionaire BAPF30B air purifiers. This filter is ideal for allergy sufferers, as it effectively extracts tiny dust particles and impurities from the air, including household dust, smoke, mould spores, and pollen. The air flow is directed through the filter, where the smallest particles are attracted to the fibres and trapped, resulting in a more pleasant indoor environment and improved air quality.
