Contaminants & Water Quality
Q: Is high TDS in my water harmful? What does it mean?
A: TDS (Total Dissolved Solids) measures the total amount of dissolved substances in water, including minerals, salts, and other particles. While a high TDS level can indicate more dissolved substances, it doesn't necessarily mean the water is unsafe—many bottled waters have high TDS due to beneficial minerals. However, some dissolved solids, like heavy metals, can be harmful. Hydrofast's filtration system removes contaminants while retaining essential minerals, ensuring your water is both clean and healthy, with a safe TDS level (≤1000 mg/L).
Q: Is TDS the best way to judge water quality?
A: Not entirely. TDS only measures dissolved substances like salts (e.g., calcium, magnesium), organic ions, and heavy metals (e.g., lead, copper), but it doesn't detect harmful bacteria, viruses, or chemicals like pesticides and nitrates. That's why Hydrofast uses advanced RO filtration, which removes 99.9% of contaminants—including those TDS can't measure—ensuring every drop is pure, safe, and up to national drinking water standards.
Q: What is the pH level of water filtered by Hydrofast water purifier?
A: Hydrofast's filtration system maintains a slightly alkaline pH, aligning with the body's natural balance of 7.35 to 7.45. Our built-in mineralization technology ensures that your water remains fresh and health-friendly. Remember to replace the filters regularly for optimal performance!
Q: Can I reuse leftover water in the raw water tank after refilling?
A: Hydrofast's reverse osmosis (RO) membrane filters water with a precision of 0.0001 microns, effectively separating pure water from concentrated impurities. The "wastewater" (higher TDS) is drained to protect the lifespan of the membrane. This water is suitable for non-drinking purposes, such as watering plants or cleaning, but it is not recommended for consumption.
Care & Maintenance
Q: What should I do if I'm not using the machine for a while?
A: If unused for less than 72 hours: The system auto-cleans after 48 hours of inactivity. You can also long press the Flush button for 5 seconds to flush the internal system.
- If unused for over 72 hours: Empty the tank, turn off the power, and store the machine in a cool, dry place. When restarting, flush three full tanks of water (just like initial setup) to reactivate the system.
Q: What is the lifespan of the filters?
A: The lifespan of a filter depends on the quality of your water and your usage patterns. Hydrofast's smart monitoring system tracks filter health in real time. With the Filter Cartridge Life Indicator, you'll always be aware of the filter's status and when it's time for a replacement, ensuring consistently pure water.
Q: How long is the shelf life of the filters?
A: Hydrofast filters have a shelf life of five years, provided they are kept in their sealed packaging and stored in a cool, dry place. You can be confident in using the filters as long as they are properly stored.
Q: How does the machine ensure that cold water remains free of contamination during storage?
A: Hydrofast's closed-loop design ensures that only clean, filtered water enters the cold storage compartment.
Q: Does the ice water system need regular cleaning to prevent bacterial growth?
A: To maintain long-term cleanliness, we recommend using food-grade citric acid descaler. After thoroughly dissolving it, pour the solution into the water tank to soak. The water will simultaneously flow into the ice tank. Perform a drain operation to clean both the water tank and the ice compartment, ensuring the drinking equipment remains hygienic.
Product & Other
Q: Is the machine noisy when filtering water?
A: Not at all. Hydrofast's RO system features a high-efficiency, low-noise pump that operates quietly. You'll only hear minimal noise during active filtration, and even that won't disrupt your daily activities.
Q: How long does it take to make cold water?
A: The initial cooling process takes approximately 50 minutes. After dispensing cold water, the machine will cool down again within 8 to 10 minutes. If no cold water is dispensed, the machine will continue to operate when water temperature is above 12°C, which may vary with room temperature. Chilled water flows at a rate of 0.39 L/min, the same as room-temperature water. The display provides real-time temperature readings, ensuring you are always aware of what to expect.
Q: Can I adjust the temperature of the cold water?
A: No, there's no temperature adjustment. There's only one "Cold Water" button. When pressed, the machine cools the water to a preset temperature. After dispensing about 300 mL (around 1 cup), the cold water will gradually warm up to match the room-temperature water in the pure water tank. The machine then restarts cooling automatically and stops once the temperature drops back to 9°C–12°C. (It works like an automatic cycle to keep the water chilled.)
Q: Why does the cold water temperature change when I dispense it?
A: The cold water container (ice tank) is connected to the room-temperature pure water tank. When you dispense cold water, room-temperature water flows into the ice tank to refill it. This mixing causes the overall temperature in the ice tank to rise until it equilibrates with the room-temperature water.
Q: Can I easily switch to room temperature water if I don't want cold water?
A: Yes, simply avoid pressing the cold water button, just press the water button, and the machine will dispense water at a normal temperature.
Q: How energy-efficient is the machine when making ice water? Is it more energy-efficient than a traditional refrigerator?
A: Yes, it's highly efficient. Here's a breakdown of its energy consumption:
- Standby mode: 2W
- Water filtration: 30W
- Cooling process: 65W
For a typical household (4 people, 40 uses/day), energy consumption is about 15 kWh per month, significantly lower than a traditional refrigerator.
