Water treatment equipment consumables―PP cotton filter

In our daily life, there are always many filtering instruments. The materials and principles of filtering instruments are actually different, so the filtering effect is also different. Funnels, filter papers, separatory funnels, etc. are commonly used in our daily life, and are also very familiar filtration instruments. The pp cotton filter element is also a widely used filter instrument, but everyone should be relatively unfamiliar. Now Guangzhou Lvyuan Water Purification Equipment Co., Ltd. will introduce to you what are the specifications of the pp cotton filter element and what are the pp cotton filter element What are the features?

What are the specifications and functional characteristics of the pp cotton filter element?




1. What are the specifications of pp cotton filter element?

The filter element should not be so unfamiliar to everyone. As far as we know, the filter element is generally an important part of the water purifier, which filters the water and achieves the role of water purification. With the improvement of living standards, people are paying more and more attention to hygiene and health, so many people will choose to buy a water purifier, so what is its effect? ??Let’s take a look: we call it pp cotton filter. It is a melt-blown pp filter element, a tubular filter element made of non-toxic and odorless polypropylene particles after heating and melting, spinning, traction, and forming. If the raw material is mainly polypropylene. It can be called PP melt spray filter element.

Model: PP-10PP-20PP-30PP-40,

Size: 10 inches 20 inches 30 inches 40 inches,

Maximum pressure difference: positive 0.4Mpa,

Water inlet pressure: 0.1-0.5Mpa,

It is not only used in water purification in large quantities. It also has a very outstanding chemical compatibility, suitable for the filtration of strong acids, strong alkalis and organic solvents. Strong dirt holding capacity, long service life and low cost.

2. Features of pp cotton filter element:

1. It can effectively remove various particles and impurities in the filtered liquid,

2. A structure with multi-layer depth, with a relatively large amount of pollution,

3. The filtration flow is very large and the pressure difference is relatively small.

4. It does not contain any kind of chemical adhesive, which is more hygienic and safe.

5. It is resistant to acids, alkalis, organic solvents, oils, and has good chemical stability.

6. It integrates surface, deep, coarse and fine filtration; it has the characteristics of large flow, corrosion resistance, high pressure and low cost. It is used to block large particles such as rust, sand, and insect eggs in the water.

3. The main application areas are:

Pharmaceutical industry: pre-filtration of various injections, medicinal solutions and injection bottle washing water, pre-filtration of large infusions and various antibiotics and traditional Chinese medicine injections.

Food industry: filtration of alcohol, beverages and drinking water.

Electronics industry: pre-filtration of pure water and ultra-pure water.

Petroleum and chemical industry: filtration of various organic solvents, acids, lye, and oilfield water injection filtration.

PP melt blown filter element can be widely used in: pure water, electroplating solution, printed circuit board, solvent, coating, detergent, medical water, oral industry, pharmaceutical injection, beverage, wine and other industries for liquid filtration, compressed air, gas filter.


The pp cotton filter element, also known as the melt-blown pp filter element, is made of non-toxic and odorless polypropylene particles. The tubular filter element is made by heating, melting, spinning, drawing, and receiving forming. It is not only used in water purification in large quantities. It also has outstanding Chemical compatibility, suitable for filtration of strong acids, strong bases and organic solvents. Strong dirt holding capacity, long service life and low cost.

Filter accuracy of filter element:

Absolute filtration accuracy: theoretically, the filtration of 100% of the marked particle size is called absolute filtration accuracy. Generally speaking, the absolute accuracy is actually the accuracy of 'tending to absolute'.

Nominal filtration accuracy: the common value of the initial filtration accuracy of the filter element. The filtering of nominal precision for the marked particle size is probability filtering. Filtration accuracy: 1μm, 5μm, etc.


Application fields of PP cotton filter element:

Pharmaceutical industry: pre-filtration of various injections, medicinal solutions and injection bottle washing water, pre-filtration of large infusions and various antibiotics and traditional Chinese medicine injections.　Food industry: filtration of alcohol, beverages and drinking water.

Electronics industry: pre-filtration of pure water and ultra-pure water.

Petroleum and chemical industry: filtration of various organic solvents, acids, lye, and oilfield water injection filtration.

PP melt blown filter element can be widely used in: pure water, electroplating solution, printed circuit board, solvent, coating, detergent, medical water, oral industry, pharmaceutical injection, beverage, wine and other industries for liquid filtration, compressed air, gas filter.

Identification of PP cotton filter element:

The solid density is higher and the pinch is firm, which means that the compressibility is also high, the filtration accuracy and the service life are longer, and the soft PP may disperse after the water pressure is high or the use time is long, causing the filtration degree to decrease and affect The normal operation of the RO machine requires PP, which is superior in quality and price, to fundamentally improve the quality of the entire water purifier.


The filter element is a new type of precision filter element. It has the characteristics of small size, large filter area, high precision, no pollution, and easy installation and replacement. PP cotton filter element, also known as melt blown PP filter element, uses non-toxic and odorless polypropylene particles , A tubular filter element made by heating, melting, spinning, traction, and receiving forming; if the raw material is mainly polypropylene, it can be called a PP melt-blown filter element. The PP cotton filter element is not only used in large quantities for water purification. It also has outstanding chemical compatibility and is suitable for the filtration of strong acids, strong alkalis and organic solvents. Strong dirt holding capacity, long service life and low cost.



pp cotton filter

PP cotton filter element is mostly used for water filtration. It can filter colloidal impurities, micro mud, rust, insect eggs, organic pollutants, minerals, etc. with a diameter of more than 5 microns in tap water. Used in water purifier equipment, the main purpose is pre-purification. PP cotton filter element mostly uses polypropylene as the main filter material.

PP cotton can also be used as a pillow filler, and PP cotton is most suitable as a pillow core. Soft and comfortable, the price is relatively cheap, easy to clean and dry, and the fluffy and soft hand feel is the most popular kind of filler for pillow cores on the market.

The replacement time of the PP cotton filter element is generally 6-10 months, depending on the local water quality and quantity.

Therefore, if you buy a household water purifier with a PP cotton filter element, in order to avoid secondary pollution of the water purifier and affect the filtering effect of the subsequent filter element, it is recommended that you replace it every 3-6 months or so. The first grade PP cotton filter element.
