Yes! In fact, cleaning your Pre-Filter regularly can help extend the life of your filters until your next filter change. We recommend giving your Pre-Filter a quick going over with a vacuum hose or extension about once per month.
Can I wash my Pre-Filter?
Yes, but if you choose to wash your Pre-Filter, you must remove it fully from the Carbon/VOC filter, hand wash it with a gentle soap, and allow it to dry completely before reattaching it to Carbon/VOC filter. You do not want to introduce any moisture onto the filters.
It is important that you never wash your UltraHEPA or Carbon/VOC Filter. Doing so will damage your filters, making them unusable.
