[Core Principle — Difference in Combination Methods]
◆ UF(Direct-flow type) Combination with water purifier — Why is it safe?
UF (Ultrafiltration) is a simple direct-flow structure: tap water → water purifier → purified water. Huwell UNDER adds a branch to the water purifier's "inlet line" — tap water passes through Huwell's 14-stage mineral filter to generate 14 types of minerals, then enters the water purifier for further purification.
① No damage to the internal circuit, filter, or pump of the existing water purifier.
② No impact on the purification function or pressure of the water purifier.
③ When separating or relocating, simply remove the branch part to restore to original state.
Most domestic major brands' basic and mid-range models use the UF method — applicable to a very wide range of households.
◆ UFOther than UF (such as RO) and appliance combination — Why disassemble the main unit?
RO has a complex structure with a pressure tank and wastewater line — unlike UF, a branch at the inlet is not possible.
Therefore, the existing filter is removed and the tubing line is directly connected to the direct-flow section.
Since disassembly of the main unit is required, ownership must belong to you.
Cold and hot water purifiers, ice water purifiers, ice makers, and coffee machines can also be applied in the same way (prior consultation required).
[Compatibility Matrix — 4 Cases]
【Case ①】 UF (direct water type) + Owned by you
→ ✅ Official compatibility · Technician installation support
• Branch connection + Owned by you → The safest combination.
• Huwell technician support · Headquarters A/S guaranteed.
【Case ②】 UF (direct water type) + On rental
→ ✅ Combination possible (Huwell advantage)
• Combination possible by branching only at the inlet without disassembling the main unit — No impact on the structure of rental products.
• Prior consultation recommended (check filter type).
【Case ③】 Other than UF (such as RO) + Owned by you
→ ⚠️ Prior consultation required · Disclaimer of responsibility
• Remove existing filter + Direct connection of tubing line to direct water inlet.
• Involves modification of the main unit structure — May affect normal operation.
We are not responsible for any damage or malfunction caused by this.
• Can also be applied to hot and cold water dispensers, ice water dispensers, ice makers, and coffee machines using the same principle.
• Free preliminary consultation is required before applying.
【Case ④】 UF, others (such as RO) + currently on rental
→ 🚫 Combination not possible.
• Main unit disassembly required → Violation of unauthorized modification by rental company (possible penalty fee).
• Combination not performed. Possible after rental ends and ownership is transferred.
RO Precautions when combining with water purifiers
RO combination involves disassembling the main unit. On the day of installation, a waiver agreement must be signed; if not signed, disassembly will not proceed and Funding can be refunded.

Frequently Asked Questions (FAQ)
📦 A. Product·Technology
Q1. What exactly is the difference between the water activator and a water purifier?
A water purifier removes impurities. A mineral water dispenser adds "mineral balance."
Q2.What is the principle behind the filter generating minerals?
The Huwell filter uses mineral materials to naturally elute minerals—similar to how spring water passes through bedrock.
Q8.Is it really okay that it doesn't use electricity?
Non-powered direct water supply—just connect to the water line, no outlet or electrical work needed.
◆ Mineral Water Dispenser PLUS → 4 AA batteries (self-powered water dispensing)
