Our direct flow 4-stage RO system is a new type of aquarium filter. Water after it has been passed through an RO system has a reduced pH*. It is an excellent source to prepare appropriate conditions for aquatic organisms.

This system is equipped with two pre-filtration stages. The first is a sediment cartridge made from spun polyester. It effectively removes sediments including sand, silt, dirt, rust, etc. The second is an extruded carbon block cartridge made from high-quality coconut shell activated carbon, which is designed to remove chlorine and volatile organic compounds.

The main filtration takes place on RO membrane, which removes 96-99% of all impurities from water. Waste water is poured into the drain.

The final 'polishing' stage is provided via mixed-bed ion-exchange resin. It consists of a carefully blended mixture of virgin raw materials, strong acid cation and strong base anion resins. It is widely recommended for all non-regenerable mixed-bed applications where reliable production of the highest quality water is required, and where the resin must have an absolute minimum of ionic and non-ionic contamination before it is used. Any pre-contamination in the resin will reduce its overall lifespan, so a high quality resin will last longer.

Our MB-115 mixed-bed formulation is regarded by all in the water purification industry as the best performing mixed-bed de-ionisation resin available, consistently out-performing every other brand, pound for pound. Colour-change resin turns from green to yellow when it has expired, meaning you have a visual indicator of when your resin will need replacing. Ordinary resin usually requires to be checked with a TDS meter, however colour-change resin means you can tell at a glance when it is time to renew the resin.

This reverse osmosis water filter, like all direct flow reverse osmosis water filters, does rely on you having a strong mains water pressure. Please do not buy this item if you do not have a good water pressure. This unit operates best at input water pressures of between 30psi (2 Bar) and 60psi (4 Bar). We would suggest that this is not suitable for use with gravity-fed cold water systems (where the water is stored in the loft). Normal UK water pressure should start from around 2 bar or above.

Our aquarium filter is factory tested and ready to use with connection hardware, tubing and instruction manual, all of which is designed to make installation and maintenance quick and easy without the need for a plumber.

It is offered as a complete set with filter cartridges, RO membrane, DI resin, additional accessories and valves to prevent the membrane from becoming dried out.

*pH of water after RO system depends on source water.

ADVISORY: Avoid cheap water filtration systems and cartridges which have no testing credentials or certifications, and often leach harmful chemicals into the water which are linked to cancer, birth defects and infertility. In addition, cheap components may also lead to membrane fouling, leaks and general poor performance. Instead, always choose VYAIR tested and certified water filtration systems and cartridges.

STAGE, PART#, COMPONENT, FUNCTION:

  • 1) PP. 10" sediment cartridge (pre-filter) melt-blown polypropylene. 5 micron sediment filter traps dirt, sediment, rust and other particulate matter.
  • 2) CTO. 10" coconut shell carbon cartridge (pre-filter). Activated carbon block filter is used to reduce chlorine, colour, taste, odour and other organic impurities.
  • 3) RO-1812-100. Thin film composite reverse osmosis membrane (100 GPD - US Gallons), 0.0001 micron. Semi-permeable membrane removes salts, minerals, metals, bacteria, viruses, cysts, TDS, hardness, fluoride, pesticides, lead, mercury, cadmium, arsenic and more. Due to the time needed to remove all these ingredients we strongly recommend purchasing a water storage tank with your RO system.
  • 4) MB-115. Mixture of cation and anion de-ionisation resin combined in a 40/60 blend. Mixed-bed demineralizer is used for final water polishing to clean the last few ions within water prior to use. A single pass through a mixed-bed ion-exchange column results in the purest water that can possibly be made.

IMPORTANT: Do not use with water that is micro-biologically unsafe or of unknown quality without adequate disinfection before or after the system. Water filtration systems can help reduce the presence of contaminants. In addition, some water filtration systems can help reduce the presence of micro-organisms or other contaminants that pose potential health risks. Regularly scheduled maintenance and replacement of the filter cartridges is recommended in order for the product to perform as specified.
Replace the filter cartridges at least every 3 or 6 months (depending on water quality).
Replace the RO membrane every 2 to 3 years (depending on water quality).

LIMITED WARRANTY: VYAIR warrants that this product is free from defects in materials and workmanship. This warranty, together with any and all warranties implied by law, shall be limited to a period of twelve (12) months from the date of original purchase. This limited warranty does not apply to failures that result from abuse, misuse, alteration or failure to properly comply with installation, or cartridge change instructions. VYAIR strongly recommends adding to all point of use filtration systems a Pressure Limiting Valve (contact us for further details) to guard against unwanted extreme water pressure events, pressure increases, surges, and water hammer which could occur in the water pipes. Not having one installed could mean that if you ever did have to claim damage caused by a burst water filter system, your claim could be denied.
