What types of harmful impurities are generally found in drinking water?

Harmful impurities found in drinking water can be classified into suspended impurities and dissolved impurities. Suspended impurities includes mud, dust, sand, bacteria, viruses, cysts, etc. Dissolved impurities become soluble in water such as pesticides, arsenic, fluoride and heavy metals salts (mercury, lead, copper, cadmium, etc).

What types of water purification technologies are available?

Most commonly used methods of purification are chlorination, boiling, ultra filtration (UF), ultra violet (UV) disinfection, reverse osmosis (RO) purification and alkaline filtration.

Why boiling alone does not make water fully safe for drinking?

Boiling only kills bacteria and viruses but does not remove harmful dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. Just as we cannot remove dissolved salts from water by boiling, similarly we cannot remove dissolved impurities from water by boiling. Presence of such impurities in water may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer.

What is Reverse Osmosis and how it works?

Reverse osmosis is a separation process in which dissolved ions, heavy molecular weight compounds, bacteria, viruses and particulate matter are removed from a liquid. Reverse Osmosis is the reversal of the natural flow of osmosis. In a water purification system, the goal is not to dilute the salt solution, but to separate the pure water from the salt and other contaminants. When the natural osmotic flow is reversed, water from the salt solution is forced through the membrane in the opposite direction by application of pressure-thus the term Reverse Osmosis. Through this process, we are able to produce pure water by screening out the salts and other contaminants.

What is alkaline filtration?

Alkaline filtration maintains the safest pH level in drinking water. This advanced water purification technology supplies health sustaining minerals such as Ca, K, Na, Mg, Fe, etc.

What are the benefits of drinking alkaline water?

  • Improves Blood Circulation
  • Reduces Inflammation and Pain in Muscles and Joints
  • Reduces Cholesterol & Blood Sugar Level
  • Anti-Aging Effects
  • Supplies Essential Minerals (Ca, Mg, K, Na, Fe, Al, F, Cl, V, Li)
  • Increases Metabolism
  • Improves Immune System
  • Powerful Anti-Oxidants & Detoxifier
  • Hydrate your body
  • Restores pH Balance In Body
  • Helps with Weight Loss


What are the disadvantages of purifiers using only UV technology?

UV purification has been popular since last few years. It does kill bacteria and viruses but does not remove dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc.

What are the disadvantages of purifiers using only RO technology?

RO purification is the latest technology to come up in the market and has gained popularity. Apart from killing bacteria and viruses, it effectively removes dissolved impurities as well. However, while doing so, it removes natural minerals also from the water which are essential to our health. Thus it renders the water totally mineral-less. Such water can prove to be dangerous in the long run as it can lead to mineral deficiency in the body.

What are the advantages of multi-layered purification?

Unlike conventional water purification processes based on a single technology, Heaven DEW water purifiers work through multi-layered purification – RO + UF + Mineral, RO + UF + UV + Mineral and RO + UF + Alkaline. It has the following distinct advantages:

  • Multi-layered purification leaves less scope for impurities to pass through.
  • Ensures bacteria and viruses are totally killed.
  • Although RO purification process removes even dissolved impurities, back-up purification by UV and UF processes makes the water 100% pure all the time.
  • Alkaline filteration maintains the safest pH level in drinking water.

Why is it essential to retain minerals in water purifier?

Natural minerals are essential for our health. In conventional water purifiers, these natural minerals get removed along with dissolved impurities. This makes the water mineral-less. Such water may be harmful to health and can cause mineral deficiency in the body. Heaven DEW water purifiers are equipped with Technologically-advanced filters, which retain essential natural minerals in the purified water.
