1. 設備的產氫模式：這類 PEM 電解水素機通常設計為可持續產氫，以滿足吸入需求。部分類似設備設有「連續運轉」模式，但也可能為了設備壽命而設定保護機制，例如運行一段時間後需要短暫冷卻。

2. 建議的吸入時長（更關鍵）：與其關注機器能開多久，醫學界對「吸入氫氣」的建議時長更有參考價值。根據 2026 年發布的氫氧醫學團體標準，對於居家使用有明確指引：

   • 每日累計時長：建議每日累計使用不少於 4 小時，可以分次進行。

   • 夜間持續使用：如果使用者能夠耐受鼻導管在夜間佩戴，推薦夜間持續吸入 8 小時。

這個建議的背後邏輯是，氫氣在體內的代謝很快，單次吸入的抗氧化效果會隨著氣體排出而迅速衰减。因此，透過長時間、持續的吸入來維持體內氫氣濃度，被認為是更有效的策略。

🫁 長時間用鼻導管吸入，會缺氧嗎？

對於 HYA-150 這款設備，在正常使用下，缺氧的風險極低。 原因在於其流量設計和鼻導管的吸入方式：

• 流量是關鍵：HYA-150 的產氫量為 每分鐘 150mL。作為對比，有資料指出，通常需要純氫流量達到每分鐘 2000mL 左右，才可能開始出現輕微缺氧的疑慮。HYA-150 的流量遠低於這個閾值。

• 鼻導管的特性：使用鼻導管吸入氫氣時，你同時仍在呼吸周圍環境的空氣（包含正常的氧氣）。氫氣只是混合在你吸入的空氣中，並不會完全取代氧氣。因此，在這種低流量、非密閉面罩的給氣方式下，造成氧氣被大量排擠而導致缺氧的可能性非常小。

💡 長時間使用的實務建議與注意事項

雖然缺氧風險低，但若要進行長時間（如數小時）的吸入，有幾點需要留意：

1. 注意鼻黏膜舒適度：長時間以鼻導管吸入乾燥的氣體，可能會導致鼻腔乾燥或不適，尤其是在流量較高或使用時間較長的情況下。可以考慮在房間內使用加濕器來緩解。

2. 確保環境通風與遠離火源：這是最重要的安全原則。氫氣是易燃氣體，使用時絕對要遠離火源、避免吸菸，並確保使用環境通風良好，以防萬一。

3. 遵從漸進原則：如果是初次使用，建議從較短的時間（如 30 分鐘）開始，讓身體適應鼻導管的佩戴和氣流，再逐漸延長至建議的 4 小時或更長。

總結來說，HYA-150 的 150mL/min 流量在鼻導管吸入方式下是安全的，缺氧擔憂極低。若要發揮其潛在效益，重點在於「累積足夠的吸入時長」，可參考每日 4 小時以上或夜間 8 小時的建議，同時注意鼻腔舒適度與用火安全。

Not necessarily — and this is one of the biggest misunderstandings in the water world.

💧 Short answer:

Hydrogen‑rich water is not automatically alkaline.
Its pH is usually neutral (around 7) unless the device also changes pH.

🧪 Why hydrogen water is not the same as alkaline water

• Hydrogen‑rich water is defined by dissolved H₂ gas, not by pH.

• Adding hydrogen gas does not change acidity or alkalinity.

• A good hydrogen generator can produce high H₂ concentration even in neutral pH water.

🔍 Where the confusion comes from

Some machines (like ionizers) produce:

• Alkaline water (high pH)

• With some hydrogen

So people think hydrogen = alkaline, but they are two different properties.

📌 Clear comparison

• Hydrogen‑rich water → Defined by H₂ concentration, usually neutral pH

• Alkaline water → Defined by high pH, may or may not contain hydrogen

• Electrolyzed water → Sometimes alkaline + hydrogen, depending on machine

🎯 Bottom line

If your hydrogen water cup is designed correctly, it produces neutral‑pH hydrogen water, not alkaline water.

If you want, I can check the specs of your specific hydrogen cup (from Shopee or Flying336) and tell you exactly what type of water it produces.

💧 What does TDS < 5 ppm mean?

🌊 TDS = Total Dissolved Solids

TDS measures how many dissolved substances are in the water.
These include:

• Minerals (calcium, magnesium, sodium)

• Salts

• Metals

• Organic matter

• Impurities

It’s measured in ppm = parts per million.

So TDS < 5 ppm means the water contains less than 5 parts of dissolved solids per 1 million parts of water — extremely pure water.

🧪 Why hydrogen cups require low TDS water?

Hydrogen generators (especially PEM/SPE types) work best with very pure water because:

• High TDS can damage the electrolyzer plates

• Minerals can cause scale buildup

• Impurities reduce hydrogen production efficiency

• Some devices will auto‑stop if TDS is too high (Flying336 does this)

That’s why Flying H2 Cup recommends:

• RO water 0 - 10 ppm

• Distilled water 0 - 2 ppm

• Mineral water          150 - 500 ppm

• TDS < 5 ppm

This ensures:

• Higher hydrogen concentration

• Longer device lifespan

• Cleaner, safer water output

🎯 Simple explanation

TDS < 5 ppm = extremely clean water with almost no minerals or impurities.
Perfect for hydrogen generation.

If you want, I can also explain:

1. Why high‑TDS water reduces hydrogen concentration

2. Whether you can use tap water

3. How to measure TDS with a meter

4. What happens if TDS is too high in your cup

Answer to the above 4 points 

💧 1. What is TDS? (Total Dissolved Solids)

TDS measures how many dissolved substances are in the water.
These include:

• Minerals (calcium, magnesium, sodium)

• Salts

• Metals

• Organic particles

• Impurities

It’s measured in ppm (parts per million).

So TDS < 5 ppm means the water is extremely pure — almost nothing dissolved in it.

⚠️ 2. Why high‑TDS water reduces hydrogen concentration

Hydrogen generators work by splitting water into hydrogen (H₂) and oxygen (O₂).
When TDS is high:

• Minerals interfere with the electrolysis reaction

• Hydrogen production becomes weaker

• More bubbles form on the plates instead of dissolving into the water

• The device may produce oxygen-rich water instead of hydrogen-rich water

• Hydrogen ppm drops significantly

In short:
More minerals = less hydrogen dissolved in the water.

⚙️ 3. Why hydrogen cups require low‑TDS water

Hydrogen devices — especially PEM/SPE types — are designed for pure water.
Low TDS protects the machine and improves performance.

Benefits of using low‑TDS water:

• ✔️ Higher hydrogen concentration (better ppm)

• ✔️ Cleaner electrolysis reaction

• ✔️ No mineral scaling on the plates

• ✔️ Longer device lifespan

• ✔️ More stable hydrogen output

This is why Flying336 recommends:

• RO water

• Distilled water

• Purified water

• TDS < 5 ppm

Your device even auto‑stops if TDS is too high — a safety feature.

🚱 4. Can you use tap water?

Generally no, unless your tap water is extremely soft.

Typical tap water TDS:

• Australia: 80–300 ppm

• Malaysia/Singapore: 50–150 ppm

• Taiwan: 100–300 ppm

This is far above the safe range for hydrogen cups.

Using tap water can cause:

• Mineral buildup

• Rust‑like deposits

• Reduced hydrogen output

• Device malfunction

• Shortened lifespan

So it’s best avoided.

📏 5. How to measure TDS with a meter

A TDS meter is simple to use:

1. Turn on the meter

2. Dip it into the water

3. Wait 2–3 seconds

4. Read the number on the screen

Interpretation:

• 0–5 ppm → Perfect for hydrogen cups

• 5–30 ppm → Acceptable for some devices

• 30–100 ppm → Not recommended

• 100+ ppm → Avoid completely

If your water is above 5 ppm, use:

• RO water

• Distilled water

• Bottled purified water

💥 6. What happens if TDS is too high in your hydrogen cup

If you use high‑TDS water:

• ❌ Hydrogen production drops

• ❌ Plates get coated with minerals

• ❌ Device may overheat

• ❌ Electrolysis becomes unstable

• ❌ Water may smell metallic

• ❌ Device lifespan shortens

• ❌ Some models will auto‑stop (Flying336 does this)

In extreme cases, high TDS can permanently damage the electrolyzer.

🎯 Simple summary

• TDS = Total Dissolved Solids

• TDS < 5 ppm = extremely pure water

• Pure water = better hydrogen production + longer device life

• Tap water = too many minerals → bad for hydrogen cups

• Always use RO, distilled, or purified water

Answer to 1-4 above

Absolutely — here is a complete, organized, and easy‑to‑use master list of all the points we discussed about TDS, hydrogen cups, water purity, and device performance. This version is polished and structured so you can use it for your own notes, training materials, or even future flyers.

💧 Complete Explanation: TDS, Water Purity & Hydrogen Cup Performance

1️⃣ What is TDS? (Total Dissolved Solids)

TDS measures how many dissolved substances are present in water.
These include:

• Minerals (calcium, magnesium, sodium)

• Salts

• Metals

• Organic particles

• Impurities

Unit: ppm (parts per million)
Meaning:

• TDS < 5 ppm = extremely pure water

• TDS 5–30 ppm = low‑mineral water

• TDS 30–100 ppm = moderate minerals

• TDS 100+ ppm = high mineral content

2️⃣ Why hydrogen cups require low‑TDS water

Hydrogen generators (especially PEM/SPE types) are designed for pure water.

Benefits of low‑TDS water:

• ✔️ Higher hydrogen concentration (better ppm)

• ✔️ Cleaner electrolysis reaction

• ✔️ No mineral scaling on the plates

• ✔️ Longer device lifespan

• ✔️ More stable hydrogen output

• ✔️ Prevents overheating or malfunction

This is why Flying336 recommends:

• RO water

• Distilled water

• Purified water

• TDS < 5 ppm

3️⃣ Why high‑TDS water reduces hydrogen concentration

When water contains many minerals, several problems occur:

• ❌ Minerals interfere with the electrolysis reaction

• ❌ Hydrogen dissolves poorly because bubbles stick to mineral particles

• ❌ More oxygen is produced instead of hydrogen

• ❌ Hydrogen ppm drops significantly

• ❌ Water becomes cloudy or metallic‑smelling

In short:
More minerals = less hydrogen dissolved in the water.

4️⃣ What happens inside the device when TDS is too high

High‑TDS water causes:

• ❌ Mineral buildup on the electrolysis plates

• ❌ White or yellow scale deposits

• ❌ Reduced hydrogen output

• ❌ Device overheating
