Explore HSA and FSA payment options for your water system
Selected products may qualify when purchased to treat a specific medical condition. Eligibility requires review and may require a letter of medical necessity.
Available for qualifying US HSA and FSA accounts. Not every shopper or purchase qualifies.
Use tax-advantaged funds for qualifying expenses
HSA and FSA funds can help pay for eligible medical expenses. Any tax benefit depends on your circumstances and plan. This is a payment option, not a store discount.
A product's eligibility review does not approve it for every person. General wellness purchases do not automatically qualify, and a doctor's note alone does not guarantee reimbursement. Check with your plan administrator before buying.
What to expect at checkout
Example screens below illustrate the payment process. Available options can vary by order.
Choose HSA/FSA at checkout
Add your selected system to the cart and continue to standard checkout. Choose the HSA/FSA payment option when it is offered. It is separate from Shop Pay express.

Complete the eligibility review
Follow the provider's prompts about medical eligibility and any required documentation. Answer health questions only in the provider's secure flow.

Review payment and keep your records
If you qualify, follow the payment instructions. Review the final amount before paying and retain your receipt and any medical documentation for your plan.

Products available for eligibility review
These products have at least one available variant marked for HSA/FSA review by our payment provider. Medical eligibility and plan requirements still apply.

HSA and FSA questions
Does every water system qualify?
No. Product, variant, medical-purpose, and plan requirements apply. A product shown here is not a promise that your purchase will qualify. Complete the provider's review and confirm your plan's requirements before paying.
Will I need a letter of medical necessity?
The products in the provider's current review require a doctor's note. Follow the medical-review process and keep any documentation you receive. A letter alone does not guarantee that an expense qualifies or that your plan will reimburse it.
Is this a discount?
No. HSA/FSA is a way to pay for qualifying medical expenses with tax-advantaged funds. Any tax savings depend on your own circumstances. Review product pricing, shipping, applicable taxes, and the final checkout total before paying.
Can I still use my regular payment method?
Yes. Use the normal Add to Cart route to see the store's available checkout methods. The HSA/FSA-specific button opens a payment flow focused on HSA/FSA and card payment. HSA/FSA is not offered inside Shop Pay express.
What if only part of my cart qualifies?
If your cart includes both eligible and ineligible items, checkout automatically splits the payment. You can pay for the eligible portion with your HSA or FSA card and the remaining portion with a regular credit card.
Who can answer questions about my account or documentation?
Your HSA/FSA administrator can explain plan rules and required records. The payment provider handles its eligibility-review process. Our team can help with product and order questions.
Eligibility and plan requirements
Freedom Water Systems does not provide tax or medical advice. General wellness purchases do not automatically qualify as medical expenses. For installed home improvements, additional IRS rules can affect the qualifying amount. Product review, payment acceptance, and a medical letter do not guarantee reimbursement or tax treatment.
Confirm eligibility with your plan administrator and consult your tax professional about your circumstances. See IRS Publication 502 and IRS Publication 969 for general information.
