1.Water cooler filters

Water cooler filters ensure that not only will you have a readily available source of water, but that water will also be as pure as possible. There are many different water cooler filter types that you can use. We’ve listed a few of these water cooler filter types for your consideration. The following is the types of usual water cooler filter.

Charcoal water cooler filter

Most water cooler filters used in the home are charcoal water cooler filters. An interesting fact is that the charcoal filtering medium used in this type of water cooler filter is made from coconut husk - something to remember if you’re ever stranded on a tropical island.

A charcoal water cooler filter should be replaced twice a year for maximum effectiveness, more often if it’s only used infrequently as disuse invites mould buildup.

Reverse osmosis water cooler filter

A reverse osmosis water cooler filter is commonly referred to as an RO membrane. Reverse osmosis technology was invented to purify water on submarines using a very fine membrane. RO water is extremely pure, but also lacking in beneficial minerals. A reverse osmosis water cooler filter should be replaced every two to three months.

Water distillers

At one time water distillation was a popular method of water cooler filtration, but informed opinion now advises against using water distillers. Distilled water lacks important minerals, and the water produced is also more acidic.

Other water cooler filters

Other water cooler filter types that are less common in the home include ultraviolet water cooler filters, backflush water cooler filters, and magnetic water cooler filters. If you’re looking for a water cooler filter for regular home use, it’s safe to go with a charcoal water cooler filter. They’re inexpensive, easy to install, and won’t remove minerals that the human body derives from drinking water.

2.Materials for water dispensers


Brass is a material formed by the combination of copper and zinc. Sometimes aluminum is added to brass alloys for greater strength and corrosion resistance. Brass has a yellow, gold-like color and is commonly used to make water dispenser faucets and connectors.


Bronze is an alloy similar to brass, except it is usually a blend of copper and tin. Bronze is very corrosion resistant and is frequently used to manufacture storage tanks or reservoirs for water dispensers.


Chrome is a thin, decorative metal plating derived from chromium, a steel-gray, lustrous metal. Chrome plating is usually applied over a nickel plate and imparts a corrosion-resistant, highly polished look. Chrome plating is commonly applied to water dispenser faucets, connectors and kitchen faucets.


Polystyrene is a solid thermoplastic polymer. Polystyrene casing is very rugged, durable, and impact resistant, and is one of the commonest materials used in water dispenser construction. Polystyrene is also used in combination with stainless steel as a water dispenser reservoir insulator.

Stainless steel

Stainless steel is an iron alloy that contains at least 10% chromium. The compound is called stainless because it is more resistant than ordinary steel to stains, corrosion, and rust. Stainless steel is used to manufacture water dispenser reservoirs.

3.How often should I change the filter on my water dispenser?

The answer depends on what type of filter your water dispenser is using and how often you use it. A water dispenser that uses a charcoal water cooler filter should have its filter changed about every six months. Water dispensers that use reverse osmosis should have a filter change every two to three months. Some filter types will become contaminated if not used for a significant period of time, so always check your water dispenser filter when coming home from a vacation or long trip. Of course if your water tastes unusual, that could be a sign that the water dispenser filter needs changing.

4.water Benefits of drinking pure, filtered

Water is essential for good health. Most of us know this yet we still don't drink enough of it. Dehydration is linked to many ailments including migraine headaches, fatigue, depression, high blood pressure, skin problems, constipation and allergies. By drinking water our bodies function better and we are more energized. Quite simply, we feel better!

The quality of water that comes out of our taps has deteriorated over the years. Chemicals are used to kill bugs. Pesticides and insecticides increasingly pollute the catchment areas while pipes and plumbing fittings age and leach impurities into the water.

A possible option is to drink bottled water. However, in some instances the quality of this water is no better than tap water, it may contain preservatives and it's much more expensive. Plus there's the unacceptable impact of plastic bottles on the environment.

The good news is that Pure Water on Tap water filters and water purifiers will eliminate pollutants whilst remaining incredibly cost effective. Whether you live in an urban or a rural area, whether you want to just filter your drinking water or are looking at whole house systems, we have a solution for you.

Once you've removed the impurities from your tap water you'll taste the clean, fresh difference. Drinking enough water won't just be easier - it'll be enjoyable!

How lonsid cooler work

1.What is Ultra Violet? What's the connection between wavelength and effectiveness in killing bacteria? What are the ways to use Ultra Violet? What are the advantages of this method and how can you combine it with other purification methods?

Ultra violet light is electromagnetic radiation.

The electromagnetic radiation map - the spectrum - is characterized by the wavelength of each wave in its group: Radio waves in Meters, Micro waves in Millimeters, Infrared in Microns, the visible light and Ultra Violet in Nanometers (One meter = 1,000,000,000 nm) and the shortest waves - X waves and Gamma radiation.

The short area between 200-300 nm is called: the "a biotic area" - deadly for live creatures. When microorganisms were radiated with lamps that produced a biotic wave length - it was found that the deadliest wavelength is 260nm.

Low pressure Mercury lamps produce 85 percent of their power in a wavelength very close to 260nm. This attribute makes them efficient in purifying water and other materials removing microorganisms.


There is a variety of methods to use UV lamps:

  • Exposing surfaces to UV light.
  • Transferring solids, liquids, gas and air through the radiation area. This transfer can take place in rooms, containers, open and closed channels and transparent pipes that has either a UV lamp in the centre or several lamps externally.


Before operating a UV system, several factors should be considered:

  1. The sensitivity of the energy that will be used for purification. This is being measured in Microwatts seconds per square centimetre. Different organisms in different development stages require different energy levels
  2. Using a UV system doesn't mean that contamination in the rest of the cooler won't occur. That's why the lamp should be positioned as close as possible to the faucet
  3. A temperature of 30-40 degrees, which is essential to the maximal production of the lamp can be obtained by the isolation of the lamp with a quartz sleeve
  4. If the lamp is being turned on often, it will wear out quickly. (The lamp life is between 7,500-10,000 hours).

The main advantages in this method ate that there are no chemical modifications taking place in the system and there are no dangerous by-products.


It's low cost, ease of use and no need for added chemicals make this method more common as a stand-alone method or in tandem with additional purification methods:

Drinking water: In home purifying water systems

Beverages: To prevent chlorine taste and chlorination by-products

In food industry: washing fruits and vegetables

Drugs and cosmetics: The standard requires the use of high quality water when creating drugs and cosmetic products

Hospitals: Dialysis, labs and even regular treatment in immune systems patients.

Water reservoirs: To prevent contamination

Sewage purification

2.What is Active Carbon? What are its qualities? What is the difference between physical carbon adsorption, chemical adsorption, and what affects the adsorption capabilities?

Removal of chlorine and organic matter is done effectively by active carbon as a function of time, contact and cloudiness of the water.

The right combination of particles in different sizes will allow adsorption of a large range of polluters.

Enlarging the carbon's surface area bigger (creating cracks and branched channels) is done by exposing the carbon to high temperatures and steam in anaerobic conditions. Enlarging the carbons surface area provides the carbon high adsorption ability and allows the negative ions of the polluters to adsorb to the carbon's positive charged surface.

The adsorption and absorption capabilities of the carbon is affected of many factors, but basically affected of:

  • The raw material's source
  • The division of the pores capacity inside the carbon

There are two types of adsorption:

Physical Adsorption: In this process, the adsorbed materials are located on the pores' surface area and are drawn with low electrostatic forces (Van der Vals). This adsorption produces a small amount of heat. An example of physical adsorption: is removal of organic materials.

Chemical Adsorption: In this type of adsorption there's a chemical interaction between the adsorbed material and the active carbon. This adsorption produces a large amount of heat. An example of chemical adsorption is the removal of inorganic compounds and formaldehyde. Organic apolaric materials are absorbed quickly on the active carbon. The more soluble the material is, the less its capability to adsorb, and that's why variables such as temperature and pH which affect its solubility, indirectly affect its adsorption.

Adsorption Capabilities

Since pores in different sizes adsorb different sized molecules, loading tests are done:

A. IODIN NUMBER: The results of this test give indication to the effectiveness of the adsorption of small molecules on the general surface area of the carbon.

B. MOLLASSES NUMBER: Gives information of large molecules adsorption capabilities.

C. TANIN NUMBER: This value helps in the assessment of carbon's capabilities in removing odours and flavours from water.

Active Carbon's features:

  • Density Bulk
  • Content Ash Total - To determine the amount of the mineral materials in the carbon
  • Hardness/Wear
  • Volume Pore Total (ml/g) A large amount of pores shows a high effectiveness of adsorption.
  • Radius Pore: The average radius is measured in Microns and changes by the carbon's type.
  • The pore volume segmentation: Each carbon type has a different
    MICROPORES, MESOPORES and MACROPORES. Carbon that adsorbs different types of gas molecules is characterized with MICROPORES. Carbon that is recommended for dichloride is characterized with MESOPORES.

3.Operating Principle

This Dispenser mainly makes the water from the humidity in the air. In other words, it totally relies on the water vapour in the air to make water. The best water making can only be achieved under the ideal environment where the humidity is around 70%--80%. Water can also be made in places with low humidity, but the speed is slow. This is also the same case for places with high humidity and low temperature. So it is better to test the humidity of every position in a room before the dispenser is placed. In a living house, positions near the kitchen or window, or spacious places, will see high humidity.

If the air water dispenser wants to reach the best operating state, the temperature of ambient environment is very important, with the ideal temperature of 24℃--29℃. However, this does not mean that the dispenser will fail to work in places where the temperature is higher or lower. More drinking water will be produced at faster speed under ideal temperature. So it is necessary to measure the indoor temperature before placing the dispenser. As water is made by converting the water vapour in the air, the diespenser will become a very powerful humidity intaker. Therefore, for the sake of health, please use this dispenser only in rooms where the humidity is ensured, or when the window is opened and the indoor and outdoor air exchange is available.

4.Installation & Operation

  1. Before the air water intaking part is installed, choose a position with good humidity, put the dispenser horizontally, and make the air outlet and inlet vacant, so as to ensure fine ventilation.
  2. Place the water dispensing part according to actual needs. Reserve 10-15cm at the back of the Dispenser to facilitate heat radiation.
  3. Connect water outlet of air intaker with the water inlet of Dispenser.
  4. Connect the return water outlet of air intaker with the water outket of Dispenser. Note: This item is not applicable to super-filtering machine.
  5. Connect the control line of Dispenser with the control end of air intaker. Turn off the “Heating” and “Cooling” switch at the back of Dispenser, and insert the power supply socket. The screen of air intaker will display the humidity of present environment, indicating the power is on.
  6. Press “ON/OFF” on the control panel and the machine will start work. After operating for a period of time (above 4 hours for first use), turn on the “Cold/ Hot” water tap, and then “Heating” and “Cooling” switches when water running from the tap is normal.
