What is a pre-filter?
Pre-filters are for capturing the larger particulate pollution – big things like dust, hair and fluff. This leaves the HEPA filter to do what it’s best at – capturing the really small particles – prolonging the HEPA filter lifespan.
What does ‘washable’ mean?
Pre-filters can be washed every 2-3 weeks for a maximum of 4 times (or until they start wearing out). This means that you can re-use your pre-filter, prolonging the lifespan of your HEPA filter. Learn why you can’t wash your HEPA filter here.
How to use it?
It sticks onto the velcro tabs on the corners of your Smart Air HEPA filter to prolong the life of your HEPA and trap bigger dust particles. Replace this every two months for optimal efficiency. When installing this prefilter, remember that the prefilter attaches to the back of the HEPA, that is, the side facing the outside.
