  • Aquafilter TLCHF-2T In-line ultrafiltration membrane 0.01 micron cartridge 1/4" NPT Sediment Cartridge Aquafilter

    Aquafilter Aquafilter TLCHF-2T In-line ultrafiltration membrane 0.01 micron cartridge 1/4" NPT

    Aquafilter TLCHF-2T In-line ultrafiltration membrane 0.01 micron cartridge 1/4" NPT. Compatible with most under-counter systems available on the market. Due to the small pore size (0,02 micron) in combination with its unique structure, which decreases from the outside to the inside, the membrane is capable of removing various contaminants such as: sand, silt, rust and other suspended impurities, most bacteria, and some viruses. Large sediment particles are blocked near the capillary surface (surface filtration) and smaller ones flow inside until they are captured by smaller pores (depth filtration). Unlike RO membranes, UF membranes are characterized by zero rejection ratio which in turn leads to quicker and more efficient delivery of clean water. Moreover hollow fiber UF membranes leave beneficial minerals intact. TLCHF-2TF is designed for cold potable water filtration. Aquafilter TLCHF-2TF Ultra filtration membrane. Fits most 1/4” water lines and requires no additional tools for installation.Specifications: Size: 10" x 2" Micron rating: 0.02 microns Filter Life: 6-12 months Max pressure: 3,5 bar Min temp.: 2'C Max temp.: 45'C

Inline water filters provide a compact and convenient way to treat water directly within a pipework system or at the point of use. Unlike conventional filter housings, many inline cartridges connect directly to the water line using standard threaded or quick-connect fittings. Their compact design makes them suitable for applications where space is limited or where a dedicated filter housing is not required.

At GroAqua, we stock a range of inline water filter cartridges from Aquafilter, covering several filtration and water treatment applications. Whether you need to improve the taste and odour of drinking water, add a final filtration stage to a reverse osmosis system or help manage scale in an appliance, choosing the correct inline cartridge is essential for effective performance.

Types of Inline Water Filter Cartridges

Different inline filters use different filtration media and technologies. Selecting the right type depends on the water quality, the application and the treatment required.

Inline Activated Carbon Filters

Activated carbon inline filters are commonly used to reduce chlorine, certain organic compounds and substances that can affect the taste and odour of water. Granular activated carbon (GAC) cartridges are frequently installed as a post-filter on reverse osmosis systems or used in compatible refrigerators and drinking water dispensers.

Aquafilter inline carbon cartridges are available in different sizes and connection types. Always check the cartridge dimensions, fittings and manufacturer's specifications before choosing a replacement.

Inline Ultrafiltration Cartridges

Ultrafiltration (UF) cartridges use a fine membrane to reduce suspended particles and other specified contaminants. Depending on the membrane specification, ultrafiltration can help reduce sediment, rust, bacteria and certain other microorganisms.

Unlike reverse osmosis, ultrafiltration does not normally remove dissolved minerals from water. This makes UF cartridges suitable for applications where particulate and microbiological filtration is required while retaining dissolved minerals. Check the individual product specifications for pore size, performance claims and compatible applications.

Inline Mineralising and Remineralising Filters

Mineralising cartridges are commonly installed after a reverse osmosis system. Reverse osmosis removes a broad range of dissolved substances, and a compatible remineralising cartridge can add selected minerals, such as calcium and magnesium, back into the treated water.

These cartridges are available in different formats and connection types. Check that the cartridge is suitable for your RO system and that its fittings match your existing water line.

Inline Water-Softening and Anti-Scale Filters

Inline water-softening and anti-scale cartridges are designed for specific applications where limescale or mineral deposits may affect equipment performance. Depending on the media used, these filters may reduce hardness minerals or help limit scale formation.

Some specialist cartridges are designed for appliances such as washing machines, while others are intended for particular water filtration systems. It is important to distinguish between filters that remove hardness minerals and anti-scale products that condition water without removing those minerals.

Inline Water Filters for Reverse Osmosis Systems

Inline cartridges are widely used as additional treatment stages in domestic reverse osmosis systems. Depending on the system design, they may be fitted before or after the RO membrane to provide additional filtration or water conditioning.

Common applications include:

  • Carbon post-filters: Help improve the taste and odour of RO water.
  • Mineralising cartridges: Add selected minerals such as calcium and magnesium after RO filtration.
  • Ultrafiltration cartridges: Provide an additional membrane filtration stage in compatible systems.
  • Replacement cartridge sets: Restore the filtration stages of compatible multi-stage systems.

If you are replacing a cartridge, check the original model number, dimensions, connection type and recommended flow direction before ordering.

Inline Filters for Refrigerators and Appliances

Compact inline water filters can also be used with compatible refrigerators, ice makers, water dispensers and other appliances. Activated carbon cartridges are commonly selected for reducing chlorine and improving the taste and odour of water supplied to these appliances.

Specialist anti-scale cartridges are also available for selected applications, including washing machines. Always confirm that the filter is designed for the appliance and water connection in question. Not every inline cartridge is suitable for every appliance or installation.

Choosing the Right Inline Water Filter

Before purchasing an inline water filter cartridge, consider the following:

  1. Filtration purpose: Decide whether you need sediment reduction, activated carbon filtration, ultrafiltration, remineralisation or scale treatment.
  2. Connection type: Check whether your system uses threaded connections, such as 1/4-inch NPT, or quick-connect fittings.
  3. Cartridge dimensions: Confirm the length and diameter of the replacement cartridge.
  4. System compatibility: Check the manufacturer's model number and compatibility information, particularly for proprietary filter systems.
  5. Operating conditions: Check the maximum operating pressure, water temperature and recommended flow rate.
  6. Replacement interval: Follow the manufacturer's guidance for cartridge replacement and service life.

Choosing a compatible filter helps maintain the performance of your water treatment system and reduces the risk of leaks or poor filtration.
