Sleep8 Sanitizing Filter Bag is made of a very durable material so you can count on it not leaking, plus there's a filter built right into the bag! The filter converts the ozone back to oxygen making this unit safe to use. The only filter you need to replace is the filter on your bag. To do that, just buy a new bag – that’s it. We recommend getting a fresh bag every 90 days.
Dimensions when flat: length 15" x width 13".
