How To Choose The Best Water Purifier For You?

Water purifiers from LG are equipped with some unique features. We have mentioned them below for your reference.

1. Multi-Stage Filtration

When it comes to purity of water, LG water purifiers can remove impurities as small as 0.0001 micrometers. Its multi-stage filtration also ensures removal of virus, bacteria, and heavy metals. So, you can be assured that only pure and safe water is provided by these water purifiers.

LG water purifier models have 5-stage RO filtration system.

Pre-Filter -> Sediment Filter -> Carbon Filter -> Reverse Osmosis -> Mineral -> UV LED lamp (based on model)

Responsibilities of Each Filter:

  • Pre-Filter – This filter is responsible for removing rust stains, big dirt particles, mud, hair, and other impurities.
  • Sediment Filter – This will eliminate residues and other pollutants present in the water.
  • Activated Carbon Filter – It will remove residual chlorine, fine particles, VOC (volatile organic compounds) and others.
  • Reverse Osmosis Filter – It will filter dissolved impurities, heavy metals, virus, volatile organic compounds, bacteria, others.
  • Mineral Booster – It is responsible for adding minerals into purified water without adding impure water.
  • UV Lamp – The UV rays emitting from the lamp will kill the bacteria, virus and other microorganisms present in the storage tank. This will make the water safer and tasty for consumption.

2. Every Fresh UV Plus

Usually, RO filter removed bacteria, virus and other microorganisms present in the water. Because of this, the need for UV filter has decreased. However, if the water is left in storage for long time, then microorganisms can grow in it. To prevent this, LG purifier recycles the water present in the tank using UV lamp (in-built). The water will be purified for 75 minutes once in every 6 hours. This process is often referred by LG as Preservation Stage. It is present only in LG water purification models.

3. Stainless Steel Tank

Unlike water purifiers from other brands that provide plastic storage tank, LG models come with stainless steel tank which is more safe and hygienic. It will maintain the water contamination free and decrease any chances of algae and bacteria growth.

According to the tests conduction in labs, stainless steel water tank that is available in LG models have shown 94.4% less E.Coli growth in 24 hours compared to plastic water storage tanks. Multiple safety measures that been considered while designing this storage tank. For example, gasket around the side of the lid and multiple locks. This safety features are often mentioned as Dual Protection Seal that will keep water sage for consumption even if water is left inside the tank for a long time.

4. 2-in-1 Care

Some LG water purifiers come with UF (Ultra Filtration) which provides water suitable for cleaning vegetables and fruits. LG water purifiers with this feature will have two outlets. The secondary outlet is available through pipe present in the right side. Water from this outlet can be used for washing vegetables, fruits and raw foods.

Outlet will not use RO filtered watered present in the storage tank. The inlet water will pass through three stage filtration and released through the secondary outlet. The 3-stage filtration process include Pre-filter, sediment filter and ultra-filtration filter.

5. Smart Display

With circular digital display, it is very easy to know the purifier mode and water level in the storage tank even at the night or dim lighting conditions.

  • Blue light represents the purifier is on drinkable water filtration mode or UV sterilization or both.
  • White coloured light represents that the purifier is in standby mode or tank is full or there is no water input supply.
  • Amber light represents the purifier maintenance time.

6. One Touch Hot, Cold & Normal

With just one touch, you can get cold water (at 5-degree centigrade minimum) and hot water (at maximum 90-degree centigrade) instantly. So, now you can prepare cocktails, smoothies, plain punch, coffee or tea by just clicking a button.

7. Digital Sterilization Kit

8. Flexible Installation

LF water purifiers can be installed as per your convenience. You can either wall-mount them or place them on kitchen counter top.

Advantages of LG Water Purifier

Compared to other water purifiers, LG models have two main benefits. We have mentioned them below for your reference.

Most of the water purifiers take bypass route for adding minerals back into RO purified water but this is not appropriate method. LG models don’t have any bypass route. They come with mineral booster which will add back minerals into water. This is the appropriate way of boosting minerals in purified water.

Usually, water purifiers don’t work well in areas with low water pressures. In such cases, service professionals from other brands cut off LPS (low-pressure switch) which will force the motor to work all the time. But LG water purifiers can run even with low water pressure.

Why is ultra-filtration filter not used in some LG models for drinking water filtration?

Actually, UF filter doesn’t have any role in drinkable water filtration system. Many brands in the market add another fine pore sized UF filter at the end of purification system just to market their models as best based on the number of filters. But once the water passes through RO, there is no need of any ultra-filtration process. It’s like passing the water from fine filter (RO purification) to coarse filter (UF filter) which doesn’t make any sense. So, placing a UF purification after RO purification is just a marketing tactic.

Frequently Asked Questions

1.How long can one store water in the purifier tank?

As the company uses food-grade plastic to build the storage tanks, still, it is better if you consume the water within three days of purification.

2.Which purifier is better electric or non-electric?
