The pre-filter should be cleaned every 2-4 weeks to increase efficiency and extend the life of your filter. You can use a soft brush or vacuum hose to remove hair, dust, and large particles. You can also use water to remove dirt and dust from the pre-filter only. However, the entire filter needs to be changed every 12-15 months.
Sorry, there was a problem. Please try again later.No HEPA filter is washable for reuse. The pre-filter can be washed, which catches the larger particles.
