Coral Pure Heavy Duty Water Filters Vs Korean OEM

Cost Savings With High Capacity Water Filter

Did you know that all our water filters are made for heavy-duty usage, supporting you and your family with good health the whole year round?

Water filters with low capacity have a shorter lifespan and require a higher frequency of change. This also means that the water gets contaminated easily, resulting in acidic drinking water that can cause numerous health hazards (development impairment, cancer, loss of bone mass etc..) and an increase in fatigue!

Make the right choice with Coral Pure!

Size Matters!

Low capacity water filters get contaminated faster and will cause water to be acidic resulting in health conditions and fatigue.

What is acidic water? 

Acidic water is any water with a pH value of 6.5 or less. pH is measured on a scale between 1 and 14, with 7 representing the neutral value. Acid water occurs naturally, as rain falls to earth soft and slightly acidic. As it absorbs minerals and dissolves solid materials, the pH of the water can rise. Water with a pH value higher than 7.5 is considered basic, or alkaline. Mineral-rich alkaline water is touted by many for its perceived health benefits and fresh spring water taste.

What causes acidic water? 

Water becomes acidic when it combines with carbon dioxide during the process of precipitation. During the hydrologic cycle, water from sources like the ocean, lakes, and streams evaporate. As the moist air rises, it cools and condenses into water vapour, creating clouds. This process is a natural form of water filtration. When water evaporates, it is stripped of water hardness, bacteria, and minerals. The water distillation process mimics this principle to purify water. Since all of the minerals have been vaporized, this water is now soft and acidic. 

When the clouds return the water back to the earth’s surface in the form of precipitation, like rain and snow, carbon dioxide (CO2) dissolves into the rainfall. This forms a weak carbonic acid and lends water a mild acidity. The average pH of rainwater is around 5.6. When it hits the earth and seeps through layers of rock and sediment, the pH will adjust depending upon the environmental conditions it encounters. If the rain is falling on calcium-rich limestone, it will absorb high mineral content and likely become hard water.


However, if it seeps through a rock bed of something like granite, the water will stay acidic. Metamorphic and igneous rocks lack the calcium to buffer the pH and neutralize the acid in the water. This means many wells are likely to have acidic water, as they are often accessing shallow groundwater for their water supplies. Water can also become acidic if from chemical runoffs or mine drainage sites. 

What does acidic water do to plumbing? 

Acidic water is extremely corrosive and destroys household plumbing. The corrosive properties of acid water dissolve the copper out of your pipes, leaving blue-green stains on your drains, in your bathtubs and sinks, and around your faucets. This is an indication that serious damage is transpiring within your plumbing system, as the acidity of the water is eroding the copper out of your pipes. If left unattended, pinhole leaks can spring and cause water damage.


If these leaks emerge behind a wall, serious flooding can occur, leaving you with considerable damages to repair. Replacing your household plumbing costs around 20% of your home’s value, so catching acid water before it brings ruin to your home is of great importance. If you have plastic water tubing in your homes like PEX or PVC, the acidic water will have a less corrosive effect on plumbing. However, acidic water also wreaks havoc on water heaters and hot water appliances. The increase in temperature actually amplifies the corrosive characteristics of the water, leading to damage and premature failure of water heaters and appliances.

The other significant problem acidic water presents is leaching. As the acid water flows through the metal pipes, it leaches the metal ions from the pipes and introduces them to your water supply. This means the water can potentially contain levels of iron, manganese, copper, zinc, and lead. Drinking elevated levels of heavy metals can be toxic, especially lead. Iron and copper discolour water and leave unsightly stains on your plumbing fixtures and in your sinks and bathtubs.  


Is acidic water bad for you? 

If the acidic water is leaching heavy metals into your water, acid water can pose health risks. Exposure to high levels of zinc and copper leads to gastrointestinal upset, including nausea, vomiting, and diarrhoea. Extended consumption of copper-heavy water can cause serious health complications, like gallstones, kidney stones, neurological damage, and even kidney and liver failure. Lead is an extremely dangerous heavy metal to consume, especially for children.


Children’s bodies experience accelerated growth and absorb contaminants more readily. Lead exposure can cause cognitive impairment, memory problems, stunted development, and seizures. In adults, exposure to lead can cause high blood pressure, kidney and nervous system diseases, miscarriages and stillbirths, strokes, and even cancer.
