      Use Your SIKA FSA/HSA Funds

      HSA/FSA FAQ Recommendations 

      1. Can I Use My HSA/FSA for Merchant name Products? 

      Yes! You can use your HSA/FSA dollars to purchase eligible products on our website using the Sika Health payment method. All eligible products will say HSA/FSA eligible under the Product Description. When you add HSA/FSA eligible products to your cart, you can select the “Sika | Pay with HSA/FSA” payment method and follow the instructions. No receipts, no reimbursements, no hassle. 

      2. What happens if I have both HSA/FSA eligible items and ineligible items in my cart? 

       If you have a mixed basket of eligible and ineligible products, Sika Health makes this very easy. When you select the “Sika | Pay with HSA/FSA” payment method at checkout, your cart will automatically be split into an eligible and ineligible subtotal. You can then add the appropriate payment method for each subtotal. Sika Health will handle the rest! 

      3. What if I don't have enough money in my HSA/FSA account to cover my purchase amount? 

      Not to worry! Sika Health can check your available HSA/FSA balance, charge that amount, and allow you to provide a backup credit or debit card to handle the rest. Enter your card details like normal and follow the prompts from Sika Health! 

      4. What if I don’t have an HSA/FSA debit card? Can I still use Sika Health? 

      Yes! If you would like to redeem your HSA/FSA funds for a purchase on our website and you don’t have an HSA/FSA card, you can choose Sika and pay with a normal credit or debit card.

In this email will be everything you need to redeem your purchase for HSA/FSA dollars, including the proper receipt to submit to your HSA/FSA administrator. Download the itemized receipt and upload it to your HSA/FSA administrator to get reimbursed for your qualifying items.

      5. My payment didn’t go through with Sika Health, why is that? 

      There are a few potential reasons why this may happen. It’s possible your HSA/FSA card has not yet been activated, or that you are attempting to purchase ineligible products with an HSA/FSA card. If you believe it is something other than that, please reach out to support@sikahealth.com.

      6. What is an HSA or FSA?

      A Health Savings Account (HSA) is a pre-tax account that lets you set aside money for qualified healthcare expenses. Typically, you can sign up for an HSA when you sign up for a High Deductible Health Plan. These accounts are individually owned so the funds roll over each year and you can take them if you leave your job.

      A Flexible Spending Arrangement (FSA) is an employer-offered benefit plan that lets you set aside money for qualified healthcare expenses. You can sign up for an FSA if your employer offers this option. It’s important to remember that FSA funds do not roll over at the end of the year (unless your employer allows it) and they immediately are returned to your employer if you leave your job. Spending with your pre-tax HSA/FSA funds helps you to save 30% to 50% on qualified health expenses. And we’re here to help you maximize your savings.

      Sika makes it easy to discover and spend on qualified items at your favorite brands. Just look for Sika at checkout and start spending smarter today.

      People Also Ask?

      Higher hydrogen concentration means greater dissolved H₂ per serving and faster diffusion into water at neutral pH.

      At the core of the Echo Flask is a Solid Polymer Electrolyte / Proton Exchange Membrane (SPE/PEM) system, the same class of technology used in medical and laboratory‑grade hydrogen generation.
      This membrane ensures:

      • High‑purity hydrogen only
      • Zero chlorine, ozone, or harmful byproducts
      • Stable, consistent output across every cycle

      This is the gold standard for hydrogen water generation: clean, efficient, and engineered for long‑term reliability.

      About Echo H2 Flask

      What is the Echo Flask?

      The Echo Flask is a portable hydrogen water generator designed to infuse water with high‑concentration molecular hydrogen using advanced SPE/PEM technology.

      How long does the hydrogen last in the Echo Flask?

      Hydrogen levels remain stable for up to 12+ hours per fill when the flask is sealed.

      What is the hydrogen concentration of the Echo Flask?

      The Echo Flask can generate up to 8 PPM of molecular hydrogen, depending on water quality, temperature, and pressure. Tested at levels of over 200 Psi and will perform optimally under normal room temperature and pressure.

      How does the Echo Flask create hydrogen water?

      It uses SPE/PEM electrolysis, the cleanest and most advanced method available.

      • Anode: 2H2O→O2+4H++4e−
      • Cathode: 4H++4e−→2H2
        Only pure hydrogen gas dissolves into the water, while oxygen is vented separately.

      Does the Echo Flask change the pH of the water?

      No. SPE/PEM electrolysis keeps the water neutral pH because no hydroxide ions (OH−) enter the drinking chamber.

      Is the Echo Flask a medical device?

      No. The Echo Flask is intended for general wellness and is not designed to diagnose, treat, or cure any medical condition.

      What makes SPE/PEM electrolysis better than magnesium tablets?

      SPE/PEM electrolysis:

      • Produces pure H₂
      • No magnesium, no metals, no residues
      • No pH shift
      • No byproducts

      Magnesium reactions produce magnesium hydroxide Mg(OH)2 and depend on water chemistry.

      What materials is the Echo Flask made from?

      The body is constructed from BPA‑free medical‑grade PPSU, a high‑performance polymer known for durability, heat resistance, and safety.

      How long does the battery last?

      A full charge provides:

      • 5–7 cycles (10‑minute mode)
      • 3–4 cycles (20‑minute mode)
        Charging takes approximately 2.5 hours via USB‑C.

      Does the Echo Flask have a self‑cleaning mode?

      Yes. A touchscreen‑activated electrolysis cleaning cycle helps maintain performance and purity.

      Can I use any type of water in the Echo Flask?

      Use filtered, purified, or bottled water for best results.
      Avoid:

      • Distilled water
      • Highly mineralized water
      • Carbonated water

      These can affect hydrogen dissolution.

      How long does the hydrogen stay in the water?

      Hydrogen naturally dissipates over time. For best results, drink within 15–30 minutes after generation.

      Is the Echo Flask safe?

      SPE/PEM(SolidPolymerElectrolyte/ProtonExchangeMembrane) electrolysis splits water molecules into hydrogen and oxygen gas. The hydrogen dissolves into the water while oxygen is vented separately through a dedicated release port. This produces pure molecular hydrogen water with no chlorine, ozone, or metal byproducts and maintains neutral pH.

      What makes the ECHO Flask different from other hydrogen bottles?

      The ECHOFlask generates up to 8 ppm of dissolved molecular hydrogen via SPE/PEM electrolysis, among the highest concentrations available in a portable bottle. Many users incorporate hydrogen water into their daily hydration routine. Individual experiences vary.

      How does SPE/PEM electrolysis work?

      SPE/PEM(SolidPolymerElectrolyte/ProtonExchangeMembrane) electrolysis splits water molecules into hydrogen and oxygen gas. The hydrogen dissolves into the water while oxygen is vented separately through a dedicated release port. This produces pure molecular hydrogen water with no chlorine, ozone, or metal byproducts and maintains neutral pH.

      Is the Echo Flask FSA/HSA eligible?

      Yes, many customers successfully use FSA/HSA cards. Check your plan or card provider for eligibility.

      What’s included in the box?

      Echo Flask

      USB‑C charging cable

      Quick Start Guide

      Does the Echo Flask connect to an app?

      Yes. It features Bluetooth connectivity and integrates with:

      • The Echo App
      • Apple Health
      • Android Health

      What is the capacity of the Echo Flask?

      The flask holds 12 oz (350 ml) of water.

      What are the dimensions and weight?

      Size & Weight

      Height: 10 inches (258mm)Width: 3 inches (76mm)Depth: 2 inches (48mm)Weight (empty): 1lb (455.5g)Weight (full): 1.8lbs

      What do customers typically experience?

      Users commonly report enjoying the ECHOFlask as part of their daily hydration routine. Individual experiences vary. The ECHOFlask is not intended to diagnose, treat, cure, or prevent any medical condition.

      How is the Echo Flask different from other hydrogen bottles?

      With proper care, the SPE/PEM system is designed for long‑term durability and consistent hydrogen output.

      Is the Echo Flask H₂ certified?

      Yes. The Echo Flask is third‑party certified to produce up to 8 ppm of dissolved molecular hydrogen. Certification verifies:

      • True SPE/PEM electrolysis
      • Accurate ppm output
      • No chlorine, ozone, or mixed gases
      • No metal contamination
      • Stable performance across repeated cycles

      Testing is performed using gas chromatography, the industry standard for measuring dissolved hydrogen.

      Do you have to refill the hydrogen?

      No refills, cartridges, or consumables are ever required.
      The Echo Flask generates fresh molecular hydrogen (H₂) every time you run a cycle using pure electrolysis:

      • Anode: 2H2O→O2+4H++4e−
      • Cathode: 4H++4e−→2H2

      Hydrogen is created directly from the water you add, no chemicals, no minerals, no tablets, no replacements.

      Does it need special water?

      Yes. For optimal performance and membrane longevity, use:

      • Deionized (DI) water
      • Reverse osmosis (RO) water

      These waters prevent mineral scaling on the SPE/PEM membrane and ensure maximum hydrogen dissolution.

      Avoid using:

      • Tap water
      • Mineral water
      • Alkaline water
      • Carbonated water

      These can reduce hydrogen output and shorten the lifespan of the electrolysis system.

      Does the Echo Flask change water pH or add metals?

      No. The Echo Flask maintains neutral pH and does not introduce metals into the water. This is because:

      • The SPE/PEM membrane isolates the drinking chamber
      • No magnesium or metals contact the water
      • No hydroxide ions (OH−) enter the drinking chamber
      • Oxygen is vented separately
      • Only pure H₂ dissolves into the water

      This ensures clean, pure hydrogen water with no chemical byproducts.

      Can I add supplements to the Flask?

      We recommend using plain water only inside the device.
      Adding powders, flavorings, electrolytes, or supplements can:

      • Interfere with electrolysis
      • Reduce hydrogen concentration
      • Leave residues on the membrane
      • Shorten the lifespan of the SPE/PEM system

      If you want flavored hydrogen water, generate your H₂ first, then mix it in a separate container.
      Note: stirring or adding ingredients accelerates hydrogen loss because H₂ naturally escapes over time.

      Can I put the Flask in the dishwasher?

      No. The Echo Flask must be hand‑washed only. Avoid:

      • Dishwashers
