FREQUENTLY ASKED QUESTIONS

HOW DOES MEGHDOOT AWG WORK?

The atmosphere holds a lot of moisture which is free for the taking. MEGHDOOT AWG uses refrigeration techniques to condense this humidity from air. Air is sucked into the system through an electro static filter. Cooled coils located in the path of air provide a temperature differential between the air and the coil surface resulting in condensation. Water is then passed through various filters to remove solids and to remove any odour & to eliminate any bacterial content. Pure drinking cold water is then supplied through the dispenser tap.

IS THE WATER PRODUCED FROM MEGHDOOT REALLY PURE AND SAFE?

MEGHDOOT produces water to international standard, which is 100% Microbe free. Our filtration process removes all external particles and dissolved organic pollutants, There by making our water completely pure, fully potable and of International standards. It not only maintains the water-soluble minerals which are essential for our body but also uses specially designed cartridges, which enhance the quality of water with essential minerals. In select models the water is further remineralized with our proprietary mineral salt mixture.

IS TAKING WATER FROM THE ATMOSPHERE HARMFUL TO THE ENVIRONMENT?

Not at all! AWG extracts water from air. Water that evaporates from ocean is 850 billion litres in a Single day which is nearly equivalent to 60 days of mankind requirement of water. In Short, moisture from atmosphere is an everlasting source of water. By extracting this water, we not only get pure drinking water but also save our ground water.

 IS THERE ENOUGH WATER IN THE AIR TO PRODUCE WATER EVERY DAY?

There are 3.1 quadrillion gallons of water in the atmosphere at any given time.

CAN I REALLY GET PURE DRINKING WATER FROM AIR THAT MAY HAVE SO MANY IMPURITIES IN IT?

Absolutely! MEGHDOOT only condenses the water vapour and generates the purest form of water. The machine has an air filter of 10 microns to remove and suspended particles in the air. The water generated is further passed through a Sediment filter that removes any water soluble substances that might be present in the water, while the Activated Carbon filters eliminate any funny smell or taste present in the water and finally the UV kills any bacteria present in the water.

IS IT EXPENSIVE TO PRODUCE WATER WITH AN AWG?

The atmospheric water generator is extremely efficient using minimal amounts of energy to produce water. Only 0.25 units of energy is consumed to produce 1 litre of water of highest quality. On an avg 1 litre of highest quality water would cost less than ₹ 2 /-, which is very economical for the quality of water produced.

DOES MEGHDOOT AWG HAVE SPECIAL POWER REQUIREMENTS?

MEGHDOOT AWG units operates on standard Power or with solar panel solar/wind power or with oil powered generators.

WILL WATER PRODUCED FROM THE AIR IN MY HOME OR OFFICE HAVE A FUNNY TASTE OR SMELL?

Absolutely not. The water generation process involves air being passed through air filters to remove any suspended particles from air andcondensing of water vapour into pure and safe water. Activated carbon present in the machine removes any dust if present.

WHY DO I NEED AWG TO BRING ME WATER ANYWAY? WHAT IS WRONG WITH THE WATER I GET FROM MY TAP?

Numerous articles have been written warning about the amount of impurities that are contained in public drinking water supplies as well as the vulnerability of public water supplies to terrorist attack. The only way to be absolutely certain that your drinking water is really pure and safe is to produce it yourself with an AWG.

WHAT ABOUT BOTTLED WATER? ISN'T THAT SAFE AND PURE?

Articles have been published revealing that some bottled water is really only reprocessed tap water. Some government studies have shown over 30% of the bottled water tested to be unsafe for humans.

IS WATER PRODUCED BY AN AWG BETTER THAN BOTTLED WATER?

Water produced by MEGHDOOT AWG is the best water on earth and it is generated right before your eyes. Bottled water in many cases is filtered city water processed in a manufacturing plant. Other bottled water is "spring" water and there are no guarantees that it is truly pure and contaminant free.

IS WATER FROM AN AWG AS GOOD AS THE WATER COOLERS I SEE IN OFFICES WITH AN INVERTED 5-GALLON BOTTLE ON TOP?

Even if the water in the bottle is good, the cooler in many cases is the problem. If it is not cleaned and regularly maintained, bacteria and algae build up in the reservoir and the water you drink may become contaminated. And who likes to handle that 40 lb. water bottle anyway? Again, MEGHDOOT AWG water is the purest water on earth.

HOW DOES THE COST AND QUALITY OF BOTTLED WATER COMPARE WITH AWG WATER?

  • Very little maintenance and supervision required

  • No skilled personnel required for operation or maintenance

  • Raw material (air) is available free of cost.

WHAT DOES PH MEAN FOR WATER?

The indicator for acidity or alkalinity is known as the pH value. A pH value of 7 means a substance is neutral, water with a pH lower than 7 is considered acidic and with a pH greater than 7 water is considered alkaline. The normal range for pH in surface water systems is 6.5 to 8.5. The range in MEGHDOOT  AWG is 7.2 pH

WHAT DOES ALKALINITY MEAN FOR WATER?

Alkalinity refers to the capability of water to neutralize acid, it is a measure of the alkaline materials that are in the water This is really an expression of buffering capacity. A buffer is a solution to which an acid can be added without changing the concentration of available H+ ions (without changing the pH) appreciably.

WHAT TEMPERATURE AND HUMIDITY DO I NEED, IN ORDER FOR MEGHDOOT AWG TO PRODUCE WATER?
