Water Filters for Family

Q：
What is (are) the special feature(s) of AP-DWS1000?
A：

The special features of AP-DWS1000 are:
(i)
A dedicated water faucet is provided to prevent cross contamination with tap water;
(ii)
It comes with a patented filtration technology that retains the essential minerals in water while reducing contaminants, like chlorine, taste and odor, particulates, cysts, leads, MTBE and VOCs1；
(iii)
It has a built-in shut-off meter to cut off the water supply when it reaches the set capacity in order to ensure that only the highest quality water is passed through;
(iv)
Its SQC™, Sanitary Quick Change, encapsulated cartridge design allows for fast and easy cartridge replacement without wrenches or water spills.

Q：
How do I know whether or not AP-DWS1000 will be as safe and effective as claimed at reducing various contaminants from my water supply?
A：

AP-DWS1000 has been tested and certified by NSF2 under NSF/ANSI Standard 423 and Standard 534.

NSF/ANSI Standard 42 applies to drinking water treatment units designed to reduce aesthetic contaminants, like chlorine, taste and odor, and particulates in water. NSF/ANSI Standard 53 addresses drinking water treatment units to reduce health-related contaminants, like lead, cyst, MTBE and VOCs that may present in water. All NSF-certified products must bear a NSF Mark. You may visit www.nsf.com to check the details of AP-DWS1000’s claims.
Q：

What kind of filtration system is AP-DWS1000 using?
A：

AP-DWS1000 is using a dual-stage multi-carbon block filtration system, which is the most effective and reliable filtration system in the market for reducing common but harmful contaminants while retaining the essential minerals in water.

Q：
What is the different between RO (Reverse Osmosis) and carbon filtration system?
A：

RO is an effective filtration system that can provide water of a high level of purity, i.e. it also eliminates almost all essential minerals your body needs, like zinc, copper, calcium, iron, etc which you have to absorb in your daily diet.

RO uses a filter membrane that can be easily attacked by chlorine and the water in Hong Kong contains a lot of chlorine during the water treatment. Over time, it is difficult to find out if the membrane is still intact or not. Therefore, its effectiveness cannot be guaranteed.

Also, the operation of the RO system infuses a great amount of water into the system and filters out only a few gallons of water for use. The wastage can be as much as 75-85% of incoming water depending on the external environment factors, like temperature.

As a result, there will be high maintenance cost and a high level of water wastage when using RO.

Carbon filtration system can reduce common but harmful contaminants while retaining the essential minerals in water.

Q：

How do we know that the filter cartridges need to be replaced?
A：

AP-DWS1000 has a built-in shut-off meter and our technician will set the capacity to “1500 gallons” during installation. When the water flow reaches that capacity, the system will automatically shut off. Or, when the filtered water comes out more slowly than normal, it means that the carbon blocks inside the filter cartridges are saturated, even though the water flow has not reached the set capacity. Then this will be the time for replacing the filter cartridges.
Q：
What is the normal life span of the filter cartridges? How much are the replacement filter cartridges?
A：

The life span of the filter cartridges is 1 year for a family of 4-6 people. It is the manufacturer's recommendation that the filter cartridges should be changed at least once a year for maximum efficiency. The cost for the replacement filter cartridges is HK$1,500, including installation.
Q：
The material used in the filter cartridges of AP-DWS1000 is PVC. Can PVC withstand high water pressure?
A：
The maximum pressure that AP-DWS1000 withstands is 375 psi according to NSF's test, and the optimum operating pressure is 25-125 psi. Therefore, it should work well under the regular household water pressure.

In order to lower the risk of bursting the filter cartridges, the technician will check on-site if the water pressure is over 70 psi during every installation. If it is above that mark, a pressure-reducing valve will be added to regulate the water pressure.
Q：
What is the use of the filtered water?
A：

AP-DWS1000 is a direct drinking water system. The filtered water can be used as follows:
(i)
Direct drinking;
(ii)
Washing vegetables or fruits for salad;
(iii)
Making coffee, tea and Chinese tea etc. after boiled;
(iv)
Cooking soup and rice.
Q：
What is the different between filtered and boiled water?
A：
AP-DWS1000 is certified for the reduction of contaminants, like chlorine, taste and odor, particulates, cysts, leads, MTBE and VOCs1 , while retaining the essential minerals in water. However, boiling has not been proved to be able to eliminate contaminants or get rid of the smell and impurities in water.




















Water Filters for Commercial
Q：
Is it necessary to use water filters in food & beverage business?
A：

Water filter systems have been widely used in food factories and restaurants around the world. In the U.S., it is required by law to use water filters in commercial kitchens.

With the customers in Hong Kong becoming more and more conscious of the hygiene in restaurants, it is high time that the catering industry started considering serving their customers with filtered water, especially when it comes to preparing coffee, tea, fresh juices and ice-cream as filtered water can bring out the best flavor of the drinks. For some top-notch chefs, it is a must to use filtered water for cooking soup and rice.

Q：
What is the use of the filtered water?
A：

The 3M™'s BEV Series is a direct drinking water system. The filtered water can be used as follows:
(i)
Direct drinking;
(ii)
Washing vegetables or fruits for salad;
(iii)
Beverage preparation in coffee machine, tea machine, ice-cream machine, ice machine, hot & cold water station, hot water dispenser;
(iv)
Cooking soup and rice.
Q：
Does the 3M™’s BEV Series comply with any water standard? Which approved company / organization sets that water standard?
A：

The 3M™’s BEV Series has been tested and certified by NSF2under NSF/ANSI Standard 423 and Standard 534.

Standard 42 applies to drinking water treatment units designed to reduce aesthetic contaminants, like chlorine, taste and odor, and particulates in water. NSF/ANSI Standard 53 addresses drinking water treatment units to reduce health-related contaminants, like cyst that may present in water. All NSF-certified products must bear a NSF Mark. You may visit www.nsf.com to check the details of BEV Series’ claims.

Q：
What kind of filtration technology is the 3M's BEV Series using?
A：

The 3M-BEV Series is using the revolutionary IMPACTechnology media (Integrated Membrane Pre-Activated Carbon Technology) for unsurpassed cartridge life and economy. A single 3M-BEV filter can accomplish what was previously the job of a two- or three-cartridge system.

The IMPACTechnology media package combines a patented pharmaceutical-grade micro-porous membrane and a patented pre-activated carbon block in a single cartridge to dramatically reduce pressure drop and eliminate the need for pre-filtration.

Q：
How do we know that the filter cartridges need to be replaced?
A：

The manufacturer recommends the user to change the filter cartridge every 6 months for maximum efficiency, or when the filtered water starts coming out more slowly than normal. That will mean that the carbon blocks inside the filter cartridges are saturated. This is the time for replacing the filter cartridges.
