Engineered for reverse osmosis systems. XIONO modules restore alkalinity and minerals to purified water.
Our flagship 11" × 2.5" alkaline post-filter for reverse osmosis systems. Five media layers (magnesium, alkaline and mineral ceramic balls and coconut-shell carbon) raise the pH of RO water from about 6.3 to 8.5–9.5, bring ORP to between −150 and −280 mV and improve taste. Rated capacity 8000 L; replacement recommended every 12 months.
Each layer has one job. Together they turn flat, slightly acidic RO water into alkaline, lightly mineralised water with a better taste.
Magnesium media shifts ORP from about +130 mV (RO water) to −280 mV at first use and around −150 mV at 8000 L, according to the manufacturer's life test.
Alkaline ceramic balls lift pH from 6.35 to 9.48 at first use and keep it at 8.5 or higher for the full 8000 L.
Mineral balls and coconut-shell carbon return minerals to RO water (TDS from 37 up to 69 ppm) and remove off-odours.
XIONO is a Polish brand that selects, tests and supplies water treatment modules for the European market. We work with an established manufacturer of filtration media and check every delivery with our own pH, ORP and TDS measurements.
We publish only measured parameters. Technical data sheets and test reports are available to B2B partners on request.
XIONO supplies RO installers, distributors and system builders with alkaline post-filters, documentation and sales support.
Choose XIONO-branded modules for resale or OEM (private label) cartridges with your own branding. We handle sourcing, quality control and import, so you receive tested stock from a European partner.
Safety first: the ceramic media are NSF certified, and water passed through the cartridge was tested by SGS for 22 heavy metals, all below detection limits. We are preparing the PZH hygienic certificate for the Polish market.
