Users of the hydrogen inhalation machine for rental must strictly follow the usage instructions for each hydrogen product and the maintenance guidelines outlined below:
※ After confirming the precautions through the notice on our company website, the user affirms that they fully understand the purpose, operation method, and precautions for using the rented hydrogen inhalation machine, and agrees to take responsibility for any improper operation.
※ If the product is intentionally damaged or improperly used, rendering it unusable, the user must compensate the full product price.
※ For any abnormalities or inquiries regarding the equipment, please contact customer service via email or phone.
※ The user agrees to and will strictly adhere to all items listed in the "Hydrogen Inhalation Machine Usage Precautions Confirmation Form."

1. Water Source: The hydrogen inhalation machine is designed to use only purified water. Please ensure to use purified water when filling the machine. As purified water is a consumable, none of the products come with purified water, so users must purchase it themselves from major stores (any brand). If any internal components of the hydrogen inhalation machine are damaged or its lifespan is shortened due to the use of "non-purified water," the company reserves the right to seek compensation from the user.

 

2.  Damage Reporting: If the user discovers any damage (including packaging) or missing accessories upon receiving the product, the user must take a photo and immediately notify customer service within 24 hours of signing for the product. The signing time will be based on the timestamp provided by the logistics. If the user fails to report any issues within 24 hours of signing for the product, it will be considered as acceptance of the product being intact and without any issues.

       3.  Product Maintenance: Please follow the maintenance guidelines for the rented hydrogen inhalation product as outlined in the precautionary checklist below.

 

Hydrogen Inhalation Machine Usage Precautions Confirmation Form
Personal Safety Precautions
1	Hydrogen is a means of self-care. This product does not claim to have any medical effects.
2	If users experience discomfort during hydrogen inhalation, they should stop using it immediately and consult a doctor to confirm their health condition.
3	Keep the product away from flames and heat sources, and ensure proper indoor ventilation.
4	The hydrogen inhalation device is not an air pump; do not use it to inflate balloons.
5	Keep children's fingers away from any gaps in the device to prevent accidents or injuries.
Consumable Usage Notes
6	For hygiene and safety, the nasal cannula should not be shared with others. It is recommended to replace it with a new one monthly. Nasal cannulas are consumables and can be purchased by users.
7	Use only purified water with the hydrogen inhalation device. As purified water is a consumable, it is not included with the product. Users are advised to purchase purified water (any brand) from major retailers.
8	The filter cartridge of the device must be replaced regularly. If the "Filter Replacement" indicator light turns on during the rental period, contact customer service to receive a new filter cartridge for replacement.
Device Maintenance Guidelines
9	Do not tilt the device during use. Maintain at least 20 cm of clearance around the device from walls and other objects.
10	Plug the power cord into a 110V power outlet. After connecting to power, the home-use hydrogen inhalation device will initiate a three-minute preheating process, during which the device will not operate. This is normal.
11	If the nasal cannula or tubing is bent or compressed, causing hydrogen to fail to flow properly, the "Blockage Indicator Light" will illuminate, and an alarm will sound. Press the start button to turn off the power, check the tubing for bends or compression, and then press the start button again to resume use.
12	If the "Low Water Indicator Light" turns on and an alarm sounds, it means the device is low on purified water. Press the start button to turn off the power, refill the water tank with purified water, and press the start button again to resume use.
13	The home-use hydrogen inhalation device will automatically stop after two hours of continuous operation, while portable devices will stop after one hour. Press the start button again to continue using.
14	If the device emits an alarm and the cause is unclear, such as overload or other issues, press the start button to turn off the power. Wait five minutes, then press the start button again. If the issue persists after three attempts, contact customer service for assistance.
15	In case of abnormal device operation not covered in the manual or website announcements, press the start button to turn off the power and contact customer service for help.
16	Users should maintain the device's appearance and cleanliness. Visible dirt should be appropriately cleaned before returning the product.

 
       4. Product Return: The company does not provide refunds or any form of discount vouchers for unused products after rental. Before returning the product, please ensure that there is no damage or dirt, and clean it properly.
   
       5.Return Inspection: Any returned product that has severe or irreparable dirt will entitle the company to seek compensation from the user. All products, except for shrink wrap,  should be returned in the original packaging (e.g., bags, color boxes, outer boxes, packaging materials, etc.). If the product is returned without its original packaging or if the original packaging is damaged, the company has the right to seek compensation from the user.※Before returning the product, please make sure to drain the purified water from the machine. If you will not be using it for more than a week, please remove the water and store it properly.
The company will schedule an inspection within seven working days after receiving the signed return of the product to check for any damage (product and packaging), missing accessories, excessive dirt, etc., and will notify the user based on the findings. The signing time will be based on the timestamp provided by the logistics.
Any damage to the returned product or packaging, or missing accessories, will result in maintenance, repair, or replacement costs. The company reserves the right to make the final judgment regarding the product's condition and to seek compensation from the user.

6.  Damage Compensation: For damage to the product (product and packaging), missing accessories, or excessive dirt, the company will base the compensation amount on the [Product Price List] and notify the user of the compensation amount. During the return inspection, a detailed check and confirmation will be conducted, and if any damage or missing items are found, the user will be notified by email or phone of the total compensation amount. If the user agrees to pay the compensation amount in a phone call or email reply (either method), the company will deduct it from the deposit balance. The remaining deposit balance will be refunded to the original credit card, with the refund process following the issuing bank's procedures (typically 30 days) to return the credit card limit in the following month; or it will be transferred to a designated account (free of charge for Hua Nan Bank, and a 15 NTD fee for other banks). If the deposit balance is insufficient to cover the compensation amount, the user will need to pay the remaining compensation amount.

     Early Termination of Rentals:

• Before the product is shipped / rental period begins:
  • If the order is canceled for any reason, 20% of the rental fee will be charged as a handling fee.
  • Example: Renting a portable hydrogen inhalation device for 90 days with a rental fee of NT$4,000 (rental period: 10/01–12/29). If the order is canceled before shipment and the rental period has not started, NT$2,000 x 20% = NT$400 will be charged as a handling fee. 

    2.  After the product is shipped / rental period begins:

• Rental fees will not be refunded if the product is returned early. Once the product is received and confirmed to be intact, the deposit will be refunded.
• Any applicable platform fees or tax differences will be deducted before refunding the deposit and rental fee.

 
     3. Termination of Rental Agreement:
        - To terminate the rental agreement early, please contact customer service by phone.

      4. Late Return
          If the product is returned late, a late fee will be charged based on the average daily rental fee for the current rental period (rounded down) plus an additional 20% of the average daily rental fee (rounded up) for each day of delay.
           Example: A customer rents a portable hydrogen inhalation device for a 90-day period starting 10/01 and ending 12/29, with a total rental fee of NT$2,000. The average daily rental fee is calculated as NT$2,000 ÷ 90 = NT$66.
If the product is returned one day late, the late fee will be calculated as NT$66 + (NT$66 x 20%) = NT$79.
The late fee will continue to accrue until the product is returned.
      5. Refunds for Deposits or Remaining Rental Fees:

•  Once the returned product is received and confirmed to be in proper condition, the deposit will be refunded within 7 business days.
