Common questions about Knix
Are Knix products HSA or FSA eligible?
All 84 Knix products Caeli lists qualify for HSA or FSA, with no letter of medical necessity needed.
Can I split a Knix purchase between my HSA or FSA card and a credit card?
Yes. At checkout Caeli charges the eligible amount to your benefit card and puts the rest on a regular credit card, in one order, and you can combine funds from more than one benefit account the same way. The receipt is stored in your Caeli account for reimbursement or an audit.
