Keep your HEPA System in good working order by replacing your filters regularly. Each kit includes two prefilters (change one filter every 6 months), and one core filter (change this every 12 months).HEPA (High Efficiency Particulate Air) filters are among the most effective filters available. They capture 99.97% of all particles, even those as small as 0.3 microns. For comparison, a human hair is 150 microns wide. HEPA filters help reduce symptoms from allergy, asthma, recurring colds and cough by removing particulates from the air. HEPA filters are so effective they are used in hospital operating rooms.
