Everything around is calm and full of moisture, with water flowing through every part of the body. Staying healthy starts with clean, pure water—free from pollutants, dyes, and additives.
If you're serious about living a healthy life, having a water purifier at home is essential. These devices are becoming more common in households, but choosing the right one can be confusing for many consumers.
With so many options on the market, it's easy to feel overwhelmed. Today, we’ll walk you through some key features that make a good water purifier stand out.
The term "pure water machine" is often used by everyday consumers to refer to a "plug-in water purifier." But behind this simple device are several critical safety and performance features that ensure clean, safe water every time.
Low Voltage Protection
Low pressure protection is one of the most important safeguards in a water purifier. It prevents the pump from running dry when there’s no water supply, which helps extend the pump’s lifespan.
This feature activates when the water pressure drops below 0.05 kg. At that point, the system automatically stops to avoid damage. However, self-priming models typically don’t require this protection.
Inlet Protection
Inlet protection ensures that the water purifier only allows water to flow into the system when it's actively producing purified water. When the unit stops, the inlet valve closes, preventing tap water from entering and wasting resources.
The quality of the inlet solenoid valve is crucial here. It needs to be both sensitive and able to withstand high pressure for reliable performance.
Wastewater Protection
Wastewater protection plays a vital role in the cleaning process of the reverse osmosis membrane. During the flushing cycle, the system fully opens the wastewater channel to remove impurities trapped in the membrane, helping it last longer.
When the system is producing water, another wastewater channel remains open to maintain proper pressure, ensuring consistent water output. The sensitivity of the solenoid valve and its ability to handle both flush and wastewater pressures are key factors in the system’s efficiency.
High Voltage Protection
High voltage protection is essential for safely shutting down the system when the purified water tank is full. Without it, the pressure vessel could overpressurize and even explode.
The sensitivity of the high-pressure switch and its durability (how many times it can open and close) are crucial for long-term safety. Unfortunately, some brands use cheaper switches to cut costs, increasing the risk of failure.
Pump Pressure Stability
To function properly, the reverse osmosis membrane requires a stable pre-pressure of around 6–8 kg. A consistent water pressure before the membrane ensures steady water production and extends the membrane’s lifespan.
While standard pumps may have fluctuating pressure levels, a high-quality pump maintains a more stable output over time. Poor-quality pumps tend to lose pressure quickly, which can reduce the system’s efficiency and overall lifespan.
So, now that you know what to look for, choosing the right water purifier should be easier. Don’t just go for the cheapest option—invest in a reliable, well-designed model that protects your health and saves you money in the long run.
