HEPA filters are the best option for allergy and asthma suffers because they catch and trap small pollutants and pollen particles, such as pollen and dust mite faeces, which would otherwise be recirculated into the air and potentially trigger symptoms.

In fact, HEPA filters remove at least 99.97% of airborne particles 0.3 micrometres in diameter. To put this into perspective, a typical human hair is 100 microns in diameter, making the size and number of particles that can escape extremely small and far beyond our eyesight's capabilities. HEPA filters are washable and reusable,because they trap these tiny dust particles keeping them clean will ensure your cleaner is working effectively and producing good suction power. However we recommend that you replace them once per year and you can purchase new filters from the spares section on our website.
