We recommend that you change out the activated charcoal in your Lomi every 3 months, or about every 45 cycles. But don't worry about remembering that – Lomi will notify you with a filter light if you haven’t changed your activated charcoal in this time!
If you don't yet have a Lomi filter subscription, or haven't purchased any replacement Lomi filter refills, check out this link to order today!
Please note: Only charcoal (Lomi Filters) purchased on our website or from our authorized Amazon retail store are valid. Using charcoal purchased or sourced from other retailers will void your Lomi's warranty.
