Air Water Coolers

Frequently Asked Questions - Watair Water Cooler


The most vital human need is always for clean, pure drinking water. While bottled water is certainly one solution to availability, delivering quantities of bottled water entails heavy expenditures in energy, transportation and money. Plus, the cost to the environment is already becoming legendary!

water from air - water coolers

Perhaps you think that all water is the same or comes from the same place, and up until now you may have been right. Water comes from a river, a lake, a well, or even caught rainwater, which in all cases is a land-based source. Companies for years have taken this water and spent huge amounts of money to set up plants to clean and purify the water to bring you all sorts of different "water", some cleaner and better than others. But the fact remains that the sources are still land-based and thus will never be 100% clean.

How Does It Work?

The atmosphere holds a lot of moisture that is free for the taking. The Watair water cooler uses refrigeration techniques to condense this humidity from air. Air is taken in to 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 which is funneled into a holding tank which has a level switch controlling the water making cycle. Water is then passed through various filters to remove solids, oxygenates, and to remove any odor & to eliminate any bacterial content. Pure drinking cold water is then supplied through the spout.

The Watair water cooler system is a humidity and temperature driven machine. This means the machine depends on the level of humidity in the air and the temperature to produce water. Ideally, the humidity level should be at least 50% or above to achieve the machine's optimum performance. In places with lower humidity level, the machine will still produce water but not as quickly, nor as much as in places with high level of humidity.

The machine also depends on the temperature to operate at its optimum level. The ideal temperature is 65 F or above. Because your Watair water cooler device works by converting the humidity in the air to water, this unit also acts as an effective dehumidifier and air purifier. In areas with high humidity, the Watair water cooler not only acts as a good water generator, but also a perfect dehumidifier to keep you healthy and ensure your home or office appliances last a long time.

Is there enough water in the air to drink?

The water cycle is all about storing water and moving water on, in, and above the Earth. Although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe. Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents. Cooler temperatures aloft allow the vapor to condense into clouds and strong winds move the clouds around the world until the water falls as precipitation to replenish the earthbound parts of the water cycle. About 90 percent of water in the atmosphere is produced by evaporation from water bodies, while the other 10 percent comes from transpiration from plants.

There is always water in the atmosphere. Clouds are, of course, the most visible manifestation of atmospheric water, but even clear air contains water -water in particles that are too small to be seen. One estimate of the volume of water in the atmosphere at any one time is about 3,100 cubic miles (mi3) or 12,900 cubic kilometers (km3). That may sound like a lot, but it is only about 0.001 percent of the total Earth's water volume of about 332,500,000 mi3 (1,385,000,000 km3).

Will it operate in areas with no humidity?

Low humidity conditions are a challenge for any system that extracts moisture from the air. The system will not produce water during the day in deserts or in very hot climates due to less humidity. However, it will still produce water at night due to the dew point factor. The machine will trip off when the humidity goes below 40% RH. So, in areas of low humidity, you simply need to keep it working overnight.

Is removing water from the air harmful to the environment?

Certainly not. Water is constantly evaporating into the air. People are condensing humidity every day using dehumidifiers and air conditioning systems inside buildings and cars. That moisture is returned to the atmosphere as it naturally evaporates.

Is the water produced really pure and safe?

Yes, the water is pure, safe and clean; as well as great tasting. Water that is produced starts out cleaner because it is produced from the humidity in the air - same as what you are breathing - rather than dirty, contaminated ground water that needs to be purified. Our filtration system is highly efficient and extremely effective. It utilizes multiple safeguards as well as UV (ultra violet) lights to eradicate bacteria.

How does Ultraviolet light kill bacteria?

Ultraviolet (UV) light has become an established water treatment disinfection technology due to its extremely effective ability to kill or inactivate many species of disease-causing microorganisms. Ultraviolet light disinfection is effective on bacteria, protozoan parasites (e.g. Giardia, Cryptosporidium), and, can also be effective for most viruses, providing sufficiently high UV dosage rates are used.

Typical UV disinfection systems involve the flow of water through a vessel containing a UV lamp, as shown below. As the water passes through this vessel, microorganisms are exposed to intense ultraviolet light energy that causes damage to genetic molecules (i.e. nucleic acids: DNA or RNA) needed for reproductive functions. This damage prevents the microorganism from multiplying or replicating in a human or animal host. Because the microorganism cannot multiply, no infection can occur. Disinfection of water is achieved when UV light causes microbial inactivation.

What are the advantages to using Ultraviolet light as a disinfectant?

The advantages of UV disinfection over other disinfection methods include:
  • No use of chemicals (or a reduced amount of chlorine chemical when it is combined with UV disinfection)
  • No known production of chemical by-products
  • Simple to install, operate, and maintain
  • Inline process requiring no contact tanks
  • Energy efficient to operate (saves on costs)

What does it cost of water production?

The answer would be dependant on local electricity costs; however, under ideal conditions, the cost of production of water will be around 20¢ per gallon assuming per unit cost of electricity is 10¢ per unit. Production cost also depends on the temperature and humidity conditions at the location and the per unit cost of electricity.

Is water produced by the Watair water cooler better than bottled water?

Water produced by the Watair water cooler is the best water on earth. 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 it is pure and contaminant free.

How do your water coolers compare to the ones with an inverted 5-gallon bottle on top?

Your Watair Water Cooler produces the purest water on earth. The water inside that big 5-gallon bottle is most likely okay, but the cooler may be another matter. If it is not cleaned and regularly maintained, bacteria and algae build up in the reservoir and the water you drink may be contaminated. And who likes to handle that 40 lb. water bottle?

How is my water cooler installed?

The Watair Water Cooler operates on 110v power and only needs to be plugged in. No outside water hook up is needed.

When will my water cooler start making water?

Water will be dispensed within 4-6 hours from startup, depending on the humidity and temperature conditions.

If there is no power can my water cooler still dispense water?

Our machines can operate on electrical power provided by the local utility or by generators. It cannot dispense water if there is no power.

Does the water get stagnant or stale if it is not used for a long time?

Water never sits still inside your Watair Water Cooler. It continuously re-circulates through the filtration system every hour to assure the freshest tasting water available.

When the reservoir is full will the machine continue to make water?

Your Watair water cooler is controlled by a computerized regulatory system. Once the reservoir is filled, the water cooler will stop making water. Once the water level drops, the water cooler begins to make water again.

How often do I need to replace filters and are they expensive?

Of course, it is dependant on the volume of water production, but generally filters will last one to two years for the Watair Water Cooler. The cost of filters is nominal.

What is the machine's life span?

If the machine is used as designed and as specified in the owner's manual and proper maintenance procedures are employed, then the unit will operate for over 8-10 years.

What is the warranty on the machines?

There is a one year warranty on all the machines from date of purchase.

What maintenance is needed?

Maintenance for the Watair water cooler is simple; it only takes a couple of minutes and it will ensure your machine will operate efficiently in producing excellent quality water.

It is recommended that the side slide out air filter on the machine be washed approximately once a week in warm water (or dishwasher). The bottom tank will need to be removed and washed every 4 to 6 weeks to remove the any film that builds up over time.

Turn the machine off and unplug. As you slide the bottom tank out, notice a small clip joining the wire that will need to be unclipped so the top cover can be removed. You can either empty the bottom tank before you remove it or afterward, into a clean container. It can be refilled once it is cleaned.

The bottom tank can be rinsed in warm water with a sponge and small amount of detergent or it can be put in the dishwasher along with the air filter. Be sure to plug the wire back in after lid goes back on.
