5)Finding responsible suppliers

      To sum up the above points, I personally think that when finding and choosing a truly responsible OEM partner the most important thing is; how do you know that your supplier is responsible?

Take a look at the following:

1 Decide whether you need to purchase full global product liability insurance every year.

As I was just saying, different countries have different water pressures which, in addition to improper use of filter bottles, can cause them to rupture at night or when people go out for a long period of time. This can lead to flooding and serious damage or loss of furniture and carpets. An OEM that purchases full global product liability insurance every year is a guarantee for the buyer.

2 Commitment to Quality

An OEM that can clearly show, in an open way to a buyer, their commitment to quality though methods, such as by: publishing information on their official website; posting "quality commitment" posters throughout their factory areas; printing "quality commitment" on their business cards along with other ways and means can allow buyers and the general public to monitor their business while, at the same time remind the OEM to maintain their commitments at all times.

3 Voluntary recall of defective products

    The biggest headache for a buyer should not be problems in supply plant quality but should rather be that these problems have gone unnoticed or have been ignored.

A responsible supplier has the responsibility to ensure that, if they either find that quality is abnormal or suspect that there is a problem with the quality of a product, they will take the initiative to recall the defective product with immediate effect, or to ask the customer to have the product modified or replaced locally, with the supplier reimbursing the buyer for the cost. This is the meaning of being truly responsible.

4 Apply for ISO-14001 international environmental management systems certification and continuing to implement the standard

Many suppliers are either trying to save costs in their factories or have no awareness of environmental protection. As a result, many supply factories have not obtained ISO-14001 international environmental management systems certification. How can such a supply factory have an environmentally friendly heart? Obtaining ISO-14001 international environmental management system certification and implementing it on a continuous basis for many years is also part of having a responsible attitude.

2. Select features according to the regional water quality characteristics.
For example: Although Taiwan is a beautiful treasured island which, not only has its own special scenery and cultural style, there are still noticeable differences in the water quality in different areas. In general, the water quality is better in the north than in the because of the high carbon content. Calcium is commonly known as hard water so drinking it means the taste is poor. If you buy a water purifier on the Internet please remember to choose the correct one for your area.

3. Understand the function of the filter. Do not listen to the exaggerated words from companies.
Each of the different materials in the filter has its own importance. For example, the PP filter can remove sediment (including larger sediment) and other impurities from the water.  Hollow fiber membranes can filter out most bacteria, and RO reverse osmosis filters can filter out more small viruses. It is recommended that consumers do their homework by first reading this article: "water filter core comparison function table"

4. With filters having standard specifications the purchase and installation in easy.
Almost every water purifier manufacturer uses a dedicated filter connector for quick and easy installation, to prevent leakage, and which is suitable for people to use on a daily basis without the need to spend a lot of time studying the filter area to replace it.
The benefits of a general specification is that it is easy for Carrefour and other large buyers to buy filters. However, the product may be of poor quality, may have assembly problems, and could leak. We suggest that you only purchase well-known domestic brand.
 

5. Regular replacement of the filter is better than purchasing a high-priced water purifier.
The purpose of the filter is to filter the harmful substances in the water, which, through long-term use, clog the pores and cause other issues. We often hear from a friend or a consumer who has forgotten to regularly replace the filter because of their busy life and who only does so when the flow of the water is reduced or when the water starts smelling. Many appear shocked when they realise they haven’t changed the filter for over a year. In these situations the residual bacteria in the filter may be far greater than in ordinary water.  The amount of bacteria in high priced, high-standard water products may cause more harm than drinking water directly. You do not want to drink water with bacteria in it. Therefore, water friends, please remember to regularly replace the filter!

 

Please remember to replace the filter regularly!

Please remember to replace the filter regularly!
Because it is important, so say it three times!

Understanding the common two, three, four, five filter water purifiers on the market.

* two-way water purifier

* three-way water purifier

* five way pure water machine

The above shows the most common combinations on the market. However, there many manufacturers have also introduced small water purifier products with a multi-material combination single filter. Make sure you have in-depth understanding of each filter material so you can make the best choice for the most suitable filter for your own water purifier.

Can you really drink purified water?

The problem with drinking water is not how much bacteria is in it but how much chlorine has been added by the Taiwan Water Company to reduce levels of bacteria.  In principle water from the water plant is in line with the standards. However, the pipelines in most areas of Taiwan are old and households use water towers for storage of water. Bacteria breeds in the pipeline and water towers meaning that most of the water cannot be drunk in its raw state. Bacteria consumed through the drinking of raw water can easily lead to diarrhea and sickness.

In addition to bacteria, there is another harmful microbial – virus that is about 20-200nm in size; much smaller than the bacteria, which is 1,000-10,000nm in size. As RO reverse osmosis membrane pore sizes are less than 1nm, viruses and bacteria can be completely blocked so the water is safe to drink.

Taiwanese poison authority Xia Jue Lin has given 10 major pieces of advice regarding food safety, one of which is the suggestion that homes should install a RO reverse osmosis water purifier, to avoid drinking water from water stations.

Choose Counter Top, Under Sink, or Tap Water Filer

Regardless of the form of the water purifier filtering is still a major consideration. The more specialised item is the tap water purifier. Due to its small size the amount of water that can be filtered is less. However, the price is cheap, and it is easy to install, especially for students living away from home or for our single friends to use.

※ The reference value for filter life is based on the amount of water users use at different times.

2. Inventor
The 1^st company invented “PP cartridge” was 『Osmonic co.,』 in USA. This type of cartridge is less expensive than string wound cartridge. The process of “PP cartridge” is quicker and cheaper. For these reasons PP cartridges are most common so far.
 

3. Function:
PP cartridge can remove substance or particle from water. Normally PP cartridge will be installed as 1^st stage in water filter.

4. Microns:
When you ask sales person『What the micron PP cartridge does?』 the sales people usually answered 1 micron, 5 or 10 microns.
And it takes more cost and higher technology to produce 1 micron PP cartridge. Of course, the function of 1 micron PP cartridge will be better, too.

Using APP to check water quality at home…

When you step inside the hypermarket and stand in front of water filter selling area the salesman always introduces you the most expansive water filters and try to convince you to purchase those filters. They intend to brainwash and give you an idea of “the more expansive the better”. Surely, the salesman promotes the high-cost water filters to consumers as they have to pay astronomical of slotting fee to hypermarket day by day. Even worse the salesman will try to add ALL the expenses to products if they cannot sell any products within a week.

It will be so kind of you showing your understanding and sympathy to salesman if there is no harm for you to purchase products not worth to its value.

Nowadays, this bull campaign situation is held in contempt in some water filter suppliers. Hence, a free APP was revealed and ones can check their home water quality easily. Even better that this APP is able to recommend you the most suitable water filter for your use. No extra fee will be charged.

Using this APP you can be an expert when choosing water filters.

Modern people understand to take care of their health, health will be superior to either eating or using, but you know ? It is possible for the water you use to be the factor which causes your body unhealthy.

Everybody knows it is healthy to drink after filtration, how about bath water? Tap water consists of chlorine, and chlorine generates “Trihalomethanes”.

What is Trihalomethanes? Trihalomethanes was generated from tap water factory, then what damage will it cause to our health ?

According to the study of Trihalomethanes, it maybe carcinogenic, causing serious damage to body.

How can Trihalomethanes enters to body to affect health ? About 80% of them will enter by the respiratory tract, and the following 20% will enter by skin contact.

So this is the reason why everybody always says that it is not necessary to take a bath too long, for the rest 20%, if it should be avoid?

The water which modern people drink all choose water filters to filter, if bath water is need to be filtered !! Don’t let our bodies to be unhappy.

Sediment PP cartridges are the basic filters which can remove small particle such as sand, mud, asbestos, silt, and turbidity from the water. They are made from melt brown PP fibers.

Normally speaking, sediment PP cartridges are used to remove all types of sedimentary particles as per the required micron rating. PP pore sizes are divided to 1 micron, 5 micron, 10 micron and 20 micron.

These materials are cheaper compared to the materials used with other cartridges and it is where sediment PP cartridges got its other name of low-cost infiltration cartridges. Also, PP cartridges prevent pressure difference during the filtration. These materials are rather preservative, safe, and inexpensive and have good filtering rates. Sediments PP cartridges are equipped for the first stage cartridge in water filters and RO systems.

There are three types of PP cartridges which are melt blown, wound filter and pleated filter. Although the melt blown cartridges’ filtering rate and service life are lower compared to other PP filters and it is the cheapest one among their kinds. Melt blown filter is also the standard one in water filters in the market.

On the contrary, the pleated filter has the best filtering rate but has the most expensive price. Furthermore, the wound filter has both high quality filtering rate and competitive price.

In addition, it is recommended to replace the PP cartridges once in 2-3 months. After using these materials for 2-3 months, you could find them discolor due to the sediments and rust. Although PP’s price is quite affordable, people should be avoided purchasing bad quality products.

If the production process is poor, this would cause the pore size too big. Plus, poor production would lead the PP to deform once contacting with high water pressure. Above situations would certainly affect the filtering rate. At result, the sediments might flow to the following filters and result in clogging.

It is suggested that you press the sediments PP cartridges to check if it is firm before purchasing. Also, you could buy from ALYA which has released high quality filtering materials to bring you clean and safe pure water.
