Osmio PRO-III-XL Ultimate Whole House Water Filter System
Ready to Transform the Water Quality in Your Entire Home?
The Osmio PRO-III-XL Ultimate Whole House Water Filter System is one of our premier models, perfect for those who demand the very best in water filtration.
Whole house systems are often paired with either salt-based or non-salt-based softeners for optimal results and a reverse osmosis point-of-use system for the ultimate gold standard in home water treatment.
Enjoy the convenience of filtered water from every tap, eliminating the hassle of using filter jugs or installing separate drinking faucets.
This unit efficiently removes chlorine, toxins, heavy metals, hormones, and fluoride, and targets harmful bacteria like E. coli and Pseudomonas.
No ongoing maintenance or system backwashing is required; simply replace the cartridge at a low cost when it expires.
Whether your home is small, medium, or large, this unit fits pipework up to 1” in diameter and performs best at flow rates up to 70 LPM.
The PRO-III-XL Ultimate is capable of eliminating numerous water impurities, including chlorine, toxins, and heavy metals, and it also eradicates any unpleasant tastes or odours from your water.
The Pro-III-XL features three separate filters and housing bowls, providing flexible installation options such as arranging them in an L shape to fit into corners.
This system consists of three individual filter housings and three filters. The setup is as follows:
Housing 1 4.5 x 20 Inch Antibacterial Grey Housing with Active Ceramics Whole House Filter. This filter is replaced every 3 years or 300,000 litres and is highly effective at the removal or reduction of a vast array of impurities in water including chlorine, hormones, fluoride, lead and so on.
This filter is also highly advanced and effective at killing and containing bacteria in water such as E-coli, Pseudomonas and other microorganisms. The filter uses a unique filtration method using a patented active ceramics blend, so it has 4 different active ceramics which treat the water in a different way and is completely unique. Not only that but the filter adds antioxidants and minerals back into the water after filtering and additionally makes water more alkaline by raising the pH value, usually increasing the pH to around 0.5 a point or more (however this could be more or less depending on a number of specific variables including the presence of certain dissolved solids and gases).
Housing 2 4.5 x 20 Inch Antibacterial Grey Housing with Carbon Block 5 Micron. This filter further reduces chlorine and nay taste and odour issues that may be present in the mains tap water.
The carbon block also reduces certain Volatile Organic Chemicals (VOC) from drinking water. The coconut base of the carbon also makes a slightly sweeter taste which is pleasant. The carbon block has a very high dirt holding capacity with virtually zero pressure drop.
The filter is rated for 46,000 litres so is usually changed every 6 months.
Housing 3 4.5 x 20 Inch Antibacterial Grey Housing with GAC and KDF Process Media Filter Cartridge. This cartridge primarily reduces the bad taste and odours of chlorine and other chemicals in the water. This filter contains Granular Activated Carbon (GAC) and Kinetic Degradation Fluxion (KDF). When these 2 are combined, they are known to kill algae and fungi, control bacteria growth and remove chlorine, pesticides, organic matter, rust, unpleasant taste and odour, hydrogen sulphide, iron, lead, nickel, chromium, cadmium, calcium, mercury and other organic compounds.
The filter is ideal for situations where you need a higher flow rate or have very low water pressure problems.
Filter Life: Approximately 12-18 months or 200,000 litres.
Includes brackets, screws, and a large housing spanner
The total footprint, when installed with the connecting nipples as depicted in the product image, measures 655mm x 606mm
Environmental Benefits
After the main active ceramics cartridge has served its purpose, you can extract the ceramics and use them to fertilize your garden, improving plant health and soil drainage. You can recycle the plastic housing with your everyday recycling.
Please note: Whole house filter systems do not remove limescale. For limescale removal, check out our Water Softeners section.
