10 inch PP cotton melt blown filter cartridge universal flat mouth accessory for pre purified water machine

Description :

  The 10 inch PP cotton filter is the first line of defense in household and commercial water purification systems, mainly solving the problem of large suspended particles such as sediment, rust, and insect eggs in tap water. As the core component of the pre purified water machine, it effectively intercepts impurities through deep filtration technology, protects the subsequent activated carbon filter and RO membrane from blockage, and extends the service life of the whole machine. This category is suitable for various standard ten inch bottle water purifiers and is a basic consumable for ensuring clear water quality and improving drinking safety. Typical operating conditions include household kitchen water purification, office water dispenser pre filtration, and small commercial water purification equipment.

  The 10 inch PP cotton filter is made of food grade polypropylene ultrafine fibers, which are formed by hot melt spraying technology and have a gradient distribution structure of inner and outer pore sizes. The standard size is 250mm ± 2mm in length, 60mm ± 2mm in outer diameter, and 28-30mm in inner diameter, suitable for universal ten inch flat mouth filter bottles. The filtration accuracy is usually between 1-5 microns, depending on the pressure difference and flow rate design. The product complies with NSF/ANSI material safety standards, is resistant to acid and alkali corrosion, and operates within a temperature range of generally 4-45 degrees Celsius. The maximum operating pressure can reach 0.4 MPa. The meltblown process ensures that the filter element has no adhesive residue, avoids secondary pollution, guarantees pure water taste, high physical interception efficiency, and large initial flux.

  When selecting, it is necessary to confirm whether the filter bottle specification is the standard "10 inch flat mouth", which is the most commonly used interface type on the market, different from snap on or special threaded interfaces. If the original machine uses a folding filter or a wire wound filter, it is necessary to check whether the installation space is consistent. Although the size is the same, there are differences in the flow area and pollutant holding capacity. This PP cotton filter is suitable for primary filtration in areas with turbid water and high levels of particulate matter; If the main source of water is residual chlorine odor, it needs to be used in conjunction with post activated carbon. Not suitable for directly removing heavy metals, bacteria and viruses, or reducing water hardness. These functions need to be completed by subsequent RO reverse osmosis membranes or soft water resin components, and the classification filtration requirements need to be clearly defined when purchasing.

  Before installing the 10 inch PP cotton filter, the inlet valve should be closed and the pressure should be released. Pay attention to the water flow direction markings (if any). There is usually no direction requirement, but it is recommended to replace it as it is. The recommended replacement cycle is 3-6 months, depending on the turbidity of the local water quality. When the surface of the filter element turns yellow or black or the water output decreases significantly, it should be replaced immediately. No cleaning is required during daily maintenance. PP cotton is a disposable consumable, and cleaning cannot restore its filtering performance and is prone to bacterial growth. Common faults include water leakage caused by improper installation, which can be solved by checking whether the O-ring seal is aging or misaligned; If there is black powder in the effluent after replacing the filter element, it is mostly due to powder loss from the activated carbon filter element, not a problem with the PP cotton itself. Simply rinse with water.
