Osmio PRO-II-A Advanced Whole House Water Filter System

Osmio PRO-II-A Advanced · Compact two-stage whole-house filtration Two-stage filtration for water throughout the home The Osmio PRO-II-A combines a 4.5 × 10-inch Active Ceramics filter with a 5-micron carbon block. Installed on the incoming cold main, it targets sediment, chlorine-related taste and odour before water is distributed to taps, showers and appliances. Explore the two stages Installation requirements Point-of-entry treatment Filter the mains supply before it travels around the property The PRO-II-A is a compact point-of-entry system for households needing broader treatment than a single sediment or carbon filter. Its two 10-inch stages retain full-flow 1-inch connections without requiring electrical power or a regeneration cycle. Two heavy-duty 4.5 × 10-inch antibacterial housings 1-inch female BSP parallel brass connections Useful complete-system flow stated up to 30 L/min 5-micron final filtration No electrical supply or regeneration cycle required 2 Two treatment stages Complementary filter media 5µ 5-micron filtration Sediment, taste and odour 30 Up to 30 L/min Published system guidance 1″ Full-flow connections Female BSP brass ports A defined two-stage sequence Two complementary filters with separate service lives Water passes through the Active Ceramics cartridge first and the carbon block second. Each filter must be monitored and replaced according to its own time or capacity limit. 01 4.5 × 10-Inch Active Ceramics Filter A patented blend of four active ceramic media, with each element performing a different treatment function. Published service life is 1–3 years or up to 300,000 litres, depending on incoming water quality and usage. 02 4.5 × 10-Inch Carbon Block · 5 Micron The final stage further reduces sediment, chlorine-related taste and odour. Published capacity is 37,000 litres, with replacement recommended every 6–12 months or sooner when conditions require. Important: Published capacities are guidance rather than a guaranteed service life. Higher contaminant levels, heavier use and declining flow can require earlier replacement. Choose it for the correct purpose Whole-house filtration does not soften hard water The PRO-II-A is intended for sediment, chlorine-related taste and odour filtration. It does not remove the dissolved calcium and magnesium that cause hard-water scale. ✓ Whole-home filtration Treats the supply before distribution around the property. + Can complement a softener Filtration and softening can work together because their roles differ. ! Not limescale removal Choose a water softener when hardness reduction is the priority. Compact full-flow installation Two antibacterial housings with flexible mounting options The standard side-by-side arrangement requires approximately 46 cm of height, 39 cm of width and 21 cm of depth. Where wall width is limited, Osmio advises that the housings can be mounted one above the other. Reinforced polypropylene heads and PET bowls Silver-based antimicrobial protection within the housing plastic EPDM bowl O-rings and pressure-release valve seals Maximum housing working pressure: 6 bar Working temperature: 4–45°C Important: Antimicrobial housing construction protects the product material. It does not mean the system disinfects incoming water. Plan before ordering Installation requirements that affect flow and reliability This system becomes part of the main plumbing. Incoming pressure, peak demand, pipe size, wall strength, bypass design and servicing space must be confirmed before installation. 01 Measure peak flow Confirm the property’s actual peak demand. The stated 30 L/min is complete-system guidance, not a guarantee for every installation. 02 Test the pressure Measure incoming pressure before installation. Osmio recommends a pressure-reducing valve when the measured pressure exceeds 5 bar. 03 Provide a bypass A three-valve bypass is recommended so water service can continue while the system is isolated for maintenance. 04 Allow servicing space Leave at least 2 inches below each bowl and adequate working space for safely removing a water-filled housing. Commissioning and filter changes Service each stage separately and protect the seals Isolate and depressurise the system before removing a bowl. Use the supplied housing spanner carefully, then clean the bowl and inspect the O-ring before reassembly. Apply drinking-water-safe silicone grease to the O-ring Open the incoming supply slowly after servicing Flush through the nearest cold tap for five minutes Initial black carbon fines or temporary cloudiness can occur Inspect every joint and bowl for leaks Commissioning and ongoing care Flush slowly, record usage and inspect the seals After installation or a cartridge change, fill the system slowly and flush through the nearest cold tap for five minutes. Inspect for leaks after commissioning and check the housings, fittings and O-rings at least every six months. 1–3 years Active Ceramics or 300,000 litres 6–12 months Carbon block or 37,000 litres Every 6 months Inspect housings, fittings and O-rings Verified technical information Osmio PRO-II-A Advanced specification Product type Two-stage point-of-entry whole-house filter Housing format 2 × antibacterial 4.5 × 10-inch housings Stage 1 4.5 × 10-inch Active Ceramics filter Stage 2 4.5 × 10-inch carbon block, 5 micron Useful complete-system flow Up to 30 L/min stated in the installation guide Maximum housing flow rating 35 L/min per individual housing data sheet Connections 1-inch female BSP parallel brass threads Maximum housing pressure 6 bar Working temperature 4–45°C Individual housing dimensions 360 mm high × 190 mm wide × 185 mm deep Approximate assembled size 460 mm high × 390 mm wide × 210 mm deep Head material Reinforced polypropylene with antibacterial technology Bowl material PET with antimicrobial technology O-ring material EPDM Housing standards listed IAPMO RT to NSF/ANSI 42, 61 and 372; CSA B483.1 Installation location Incoming cold main before it branches around the property Power supply Not required Included accessories Metal brackets, head-mounting screws and housing spanner Installation information Read the manual before arranging the plumbing The guide covers pressure checks, bypass planning, filter order, mounting, O-ring preparation, commissioning and cartridge replacement. ↓ Open the installation manual Official Osmio PDF · opens in a new tab Continue browsing Compare systems and plan future maintenance W Whole-house filters Compare point-of-entry filtration systems → O Shop Osmio Browse Osmio systems, filters and accessories → F Replacement filters Find cartridges for planned maintenance → Helpful answers Frequently asked questions What is the difference between PRO-II-A and PRO-II-XL? The PRO-II-A uses 4.5 × 10-inch cartridges and is listed for useful flow up to 30 L/min. The PRO-II-XL uses larger 4.5 × 20-inch cartridges and is listed for useful flow up to 40 L/min. Will the PRO-II-A remove limescale? No. It is a filtration system rather than an ion-exchange water softener, so it does not remove the dissolved calcium and magnesium that cause hard-water scale. What flow rate should be used when sizing it? Use the complete-system guidance of up to 30 L/min, not the separate 35 L/min maximum rating of an empty individual housing. Cartridge condition, incoming pressure, pipework and peak demand all affect the flow available in practice. How often are the filters replaced? The Active Ceramics filter is listed for 1–3 years or 300,000 litres. The carbon block is listed for 6–12 months or 37,000 litres. Replace either cartridge sooner if water quality or declining flow requires it. Does the antibacterial housing disinfect the water? No. The silver-based antimicrobial additive protects the housing material. It is not a substitute for UV treatment or another validated microbiological barrier. Should a bypass be installed? Yes, Osmio recommends a three-valve bypass where space permits. This allows the filter to be isolated for maintenance while retaining a route for water service. Can the system be installed outside? The manual permits an external installation only when the system and pipework are properly boxed, weatherproofed and protected from freezing. A suitable frost-protected internal location is preferable. Premium product support Need to confirm the flow, pressure or installation space?
