Why do we need to filter our water?

Even water that looks clear may contain dirt, minerals, chemicals and other impurities that affect its smell or
taste. It may even contain microbes that could endanger your health. Pollutants can enter water at any
point of water cycle, such as lakes, rivers, and ponds.

Causes of contamination include:

  • Agriculture Runoff

    Water used in farming contains
    fertilisers, pesticides / herbicides
    and other pollutants

  • Storm Water Runoff

    Rainwater flowing through drains
    and ditches picks up all kinds of
    contaminants

  • Leaking Landfills

    Various contaminants and toxic
    chemicals from garbage can
    leach into the groundwater

  • Industrial Discharge

    Factory waste is often
    discharged directly into
    water bodies

  • Personal Care /
    Household Products

    Detergents, medicines, makeup
    and other contaminants go down
    the drain and into water sources

  • Rusting Pipes

    Water picks up rust and
    other sediments from the
    corroded pipes

What’s in your water supply?

What should you test your water for?

Total dissolved solids (TDS)

What is it? Caused by: Measured in:

Contaminants smaller than 2 microns. Moderate to high TDS changes water’s taste and odour and poses health hazards.

Weathering and erosion, as well as human activities, which cause materials to be dissolved in water.

Parts per million (ppm) (equivalent to milligram per litre of liquid water).

National standard for drinking water: 1000mg / l

Turbidity (water clarity)

What is it? Caused by: Measured in:

Suspended particles in water. The higher the turbidity, the more particles there are.

Soil erosion, high levels of nutrients, various waste products and pollutants, bottom-feeding organisms which stir up sediment in the water.

Nephelometric Turbidity Unit (NTU). The lower the NTU, the clearer the water is.

National standard for drinking water: less than 5 NTU

Colour of water

What is it? Caused by: Measured in:

The more colour water has, the less transparent it is.

Dissolved substances in water.

True Colour Units (TCU). Lower TCU means there are fewer dissolved substances in water, making the water more transparent.

National standard for drinking water: 15 TCU

pH-level of water

What is it? Caused by: Measured in:

“Potential hydrogen” is a measurement of a substance‘s hydrogen level.

Water pH varies depending on weather, human activity, and natural processes.

A scale of 0 to 14. Water can be acidic (pH 0 to 7), neutral (pH 7) or alkaline (pH 7 to 14).

National standard for drinking water: 6.5-8.5 pH

Total iron

What is it? Caused by: Measured in:

Total iron includes all of the different forms of iron that exists in water, such as ferrous or ferric iron, complexed iron, or iron oxides (rust).

Iron exists in natural water sources but may also come from industrial wastes, iron refineries, or corrosion of metals.

Milligram per litre of liquid water.

National standard for drinking water: less than 0.3 mg / l

Hardness of water

What is it? Caused by: Measured in:

Water with a high mineral content that causes calcification and lime scaling.

Water seeping through limestone and chalk which absorbs the minerals in them.

Milligram per litre of liquid water.

National standard for drinking water: less than 500 mg / l

Total coliform count

What is it? Caused by: Measured in:

Indicates the bacteria level in water.

Found in digestive tracts of animals and humans. It is excreted in their wastes and absorbed into plants and soil.

Total number of coliform bacteria.

National standard for drinking water: 0 total coliform

The proof is in the water

While different applications require different levels of water quality, what is most important is the
reliability of the filtration system to deliver on the requirements. As the water filtration pioneer in
Malaysia, Bacfree sets the standard in this area. Our filters have helped millions attain not just
clean water, but Bacfree Clean Water. See the results for yourself.
