2022.05.22

 

(1)Introduction

The filter bottle/filter shell can generally be divided into two styles. One is where the filter material is directly filled into the filter shell for use. The other is used together with the filter element to filter. Generally speaking, filter bottle selection is mainly based on the demand specifications of the incoming and outgoing water and is divided into 2 points, 4 points, 6 points, etc., as well as the material and size of the filter shell. Therefore, this article specially organizes the manufacturers of filter bottles (filter housings) in Taiwan as an important reference for your selection of filter bottles (filter housings).

 

Everyone knows that the filter is the core of the water purifier. However, the most important role that of the filter bottle (filter housing), which protects the filter, is often overlooked.

The quality of the filter bottle (filter housing) directly affects whether the water purifier will leak and burst.

The filter bottle is a device for the installation of the filter core, and it is also one of the indispensable accessories of the water purifier.

There is no filter cartridge filter that cannot filter. When people choose water purifiers, they often only pay attention to the function of the filter core, the appearance of the water purifier and the cost considerations. The filter bottle, which is usually forgotten, is actually one of the many components of the water purifier and plays a very important role and task.

 

A filter housing ruptures due to the impact of water pressure, causing water leakage, and it will burst instantly because it is unable to withstand excessive water pressure.

The water pressure in the place where we live will also affect the size of the water hammer, due to the relationship between the floor we live on and differences between day and night, which pose a great threat to the filter bottle. The most common problem is that the filter bottle bursts and leaks. Pay special attention to the following points:

 

  1. Durability of the filter bottle
  2. O-ring tightness and the burst value of the filter bottle.
  3. Whether the design of the water inlet and outlet holes of the inner teeth can withstand the extrusion of the tube teeth without breaking.
  4. The hydrophilicity, weather resistance, and impact resistance of the filter bottle material.

 

(2)What are the benefits to the water purifier factory

Did you know that in our daily life, most of the branded products we touch are actually OEM and OEM produced? A factory has its own professional technology which, combined with the brand advantage of the brand owner, allow the two to complement each other to achieve a win-win situation.

Therefore, it is very important to carefully choose a qualified manufacturer. In addition to adopting the division of labor model, the factory only needs to be responsible for the improvement of product quality, production capacity and professional technical ability, while the brand owner does not need to invest in additional production equipment costs. Entrusting its manufacturing to a professional factory can also greatly reduce costs, shorten the time to market for new products, and maximize the added value of the brand to ensure maximum profits.

 

(3)What are the selection criteria?

The following lists the conditions for selecting OEM/ODM manufacturers of water purifiers:

1. Does the factory have international certification?

 

Certification such as ISO9001 and ISO14001 will be a better choice. (Refer to Note 1)

ISO certification bodies are all authoritative organizations, recognized by the state, that are both rigorous and prudent in auditing the quality and environmental systems of enterprises.

For the internal part of the enterprise, quality and environmental management can be carried out in accordance with the strictly audited international standardization process to strengthen the level of internal management level within the company. The implementation of the international ISO9001 quality management system can not only improve product quality but can also enable enterprises to enhance their own advantages in a number of product quality areas when competing with others. By applying for international product certification, you can comply with the regulations in product design and production process using materials that will not harm human health nor cause environmental pollution.

 

Note 1: The International Organization for Standardization was established on February 23, 1947. It is an international standards establishment body that formulates international standards for industry and commerce around the world.

ISO is headquartered in Geneva, Switzerland, and currently has 164 member states. The organization is defined as a non-governmental organization and its official languages are English, French and Russian. Participants included national standards bodies and major companies in each Member State. (For full details, please refer to Wikipedia)

 

2. Do you have export experience?

 

Buyers who are looking for OEM/ODM contract manufacturing for water purifiers can communicate with you more easily. In addition, there are many proper nouns used within the water purification industry. It is a great bonus for buyers to choose a contract factory with export experience who are familiar with the export process. In addition, different countries have different specifications for water purifiers, which means that experienced factories can both provide solutions and reduce ineffective communication.

3. Have you set up a laboratory, purchased product liability insurance, etc.?

 

OEMs take out product liability insurance, not only to reassure buyers, but also to remind the OEMs to strengthen their quality awareness and to reduce the risk of claims, which provides a positive image for enhancing corporate responsibility.

By choosing a factory with a laboratory, you can judge whether the factory attaches great importance to product quality, and can check whether the factory's laboratory verifies the reliability of each product in accordance with the testing specifications of the National Sanitation Foundation (NSF). .

In addition, it is necessary to check whether the factory always implements the following quality control processes:

 

·         IQC incoming inspection

·         IPQC process inspection

·         PQC semi-finished product inspection

·         FQC final inspection

·         OQC shipment inspection

 

4. Accepts OEM orders from buyers?

 

It is also necessary to evaluate whether the factory can tailor-make exclusive customized products for the buyer. The factory itself must have the capabilities of product design, manufacturing, assembly, quality control, etc., before it can be awarded the contract for OEM production. The factory can also assist the buyer with professional services such as design, development and so on.

To assess whether a factory has adequate capabilities, the following four items can be checked:

 

·         Production equipment: automatic machine equipment, production line, ultrasonic rotary melting machine, water test/air test machine...etc.

·         Injection equipment: injection molding machine (equipped with robotic arm)...etc.

·         Product testing equipment: 3D projector, MI plastic melt index detector, specific gravity scale, microbial testing, various water quality analysis instruments...etc.

·         Customized development capability: It does not simply outsource but also has design capabilities. It is necessary to understand the development trend of the water purification market and then provide buyers with design and development in the correct product direction, which can help them to avoid taking the wrong path. In combination with the buyer needs and technology integration development costs can be reduced, allowing new products to be launched on schedule.

 

5. Do you have your own production line, and can you control the delivery time and quality by yourself?

 

It is only by having our own production line that we can take hold of exact delivery times, avoiding the problem of often being unable to provide a delivery time. If we can't reply to the buyer's delivery date immediately, we will not be able to order shipping with immediate effect, especially during the current epidemic, when shipping schedules and sea freight are both generally uncontrollable, which is relatively important. Another key point is quality control. The visible production process allows customers to not worry about corners being cut on the product or materials mixed with recycled materials, affecting the quality of the product.

 

6.To become a qualified water purification equipment factory, it is necessary to have the following 4 major items

 

  1. Complete and sophisticated production equipment
  2. Injection equipment (because about 80% of water purification equipment is composed of plastic raw materials, the quality of the key and important components is vital, which can only be controlled and achieved if the components are produced by the factory, as well as the control of a smooth delivery).
  3. Product testing equipment
  4. Customized development capabilities

 

(4)The common filter bottle specifications on the market

 

The filter bottle used in household water purifiers is generally 10 inches in length, and usually comes in two styles: white and transparent.

 

1. Filter bottle material: PP, AS, PET, and stainless steel.

 

Description: Food grade raw materials.

 

The most commonly used material is PP polypropylene (usually white) or AS styrene-acrylonitrile resin plastic (usually transparent), also known as SAN.

The better the filter bottle material, the stronger its pressure resistance. The thickness of the filter bottle also affects the pressure resistance and strength of the filter bottle.

In theory, the larger the thickness, the stronger the pressure resistance and strength, but this increases the weight and cost, so the thickness has to be appropriate.

Two different plastic materials, PP and AS, are most commonly used in the water purification equipment industry. Firstly, they are reasonably priced. Secondly, they are non-toxic. Thirdly, they are easy to store and process. We will analyze their characteristics with these two items:

 

PP Features:

  1. High impact resistance with strong mechanical properties: PP is most suitable for filter bottles with high water pressure and can resist water hammer without breaking. It is

resistant to a variety of organic solvents as well as acid and alkali corrosion: In industrial water, there is often too much acidic or too much alkaline water, and PP plastic can withstand these special waters.

 

AS Features:

  1. Good light transmission: It is convenient to use the naked eye to judge the contents (for example: whether the filter core is dirty).
  2. Greater heat resistance: Outdoor water temperatures are often as high as 50-60 degrees C (e.g.: Middle East countries), AS material is therefore the favorite choice of water filtration equipment manufacturers.
  3. Can improve both mechanical and chemical properties: This advantage is the same as that of PP plastic materials.

 

AS disadvantages:

Strong rigidity. Compared to PP material it is less resistant to water hammer and water pressure, unless the product design structure is strengthened or the thickness of the filter bottle is increased, but it will increase the material cost.

 

 

2. Inlet and outlet pipe diameter (interface size): 1/4" (2 points), 3/8" (3 points), 1/2" (4 points), 3/4" (6 points), 1" (one inch)

 

Description:

Most household water purifiers use 1/4 inch (2 points) pipes, and if they are used in water towers, most of them are 1 inch.

The size of the pipe diameter affects the flow of water out of the filter bottle. If the water output of a general household water purifier is too large (more than 3 points), the filtering effect of the filter core will be reduced, because the flowrate in the filtration is too fast to absorb too many impurities in the water or to remove chemical substances in the water, such as: residual chlorine, pesticides, calcium and magnesium ions, heavy metals...etc.

 

3. Filter bottle color: white, black, clear, blue, or special color.

Description: The standard configuration of commonly used water purifiers is: three. The first is transparent, while the second and the third are white bottles.


4.Length: 5 inches, 10 inches, 20 inches

Description: General household is 10 inches

 


5.Diameter: 2.5 inches (little fat) or 4.5 inches (big fat).

Description: It is dependent on the demand; the general household filter bottle is 2.5 inches, and the filter bottle for water towers is usually 4.5 inches.

(2.5 inches and 4.5 inches refer to the outer diameter of the filter element itself and not the filter bottle).

6.Water-stop O-ring: single O-ring or double O-ring.

 Description: These are important components whose main function is to seal or prevent water leakage when the machine is working

 


7. Air release button (pressure relief button): 1/4 inch (mostly not attached), 1/2 inch (most of the above sizes will have an air release button).

Note: When replacing the filter element, lightly press the pressure relief button to release the pressure in the bottle, so that there is no air remaining in the filter bottle, resulting in a smooth water discharge.

 


8. Inlet and outlet threads: NPT, PS, and BSP.

Description: American and British standards are the two major threads currently used in the United States and the United Kingdom, respectively.

American regulations (NPT/ NPS) and British regulations (BSPT, R/ BSPP, G) are commonly used in Taiwan.

The American National Standard Pipe Thread Standard, commonly referred to as the National Pipe Thread Standard, is the technical standard for threads used on American National Threaded Pipe and Fittings. British Standard Pipe, a thread standard widely used internationally, includes the mating of external threads and internal threads (female teeth). Equal to the US NPT standard, it is often used as a thread standard for pipes and pipe fittings.

   

 

In addition to the above filter bottle specifications, housings are also divided into the following names

Quasi-type filter housing

Length: 5"/10"

Water inlet and outlet: 2 points / 3 points / 4 points

The more commonly used colors are: transparent/white/blue
