Powerful yet compact reverse osmosis system with the innovative storage tank. RO-70S is one the most efficient and versatile domestic RO systems in the world given its high performance, water efficiency and incredible economic feasibility. Easy DIY click & turn cartridge replacement. HOW IT WORKS: The K1 filter with AQUALEN microfibre technology removes sand, rust and suspended solids down to 10 microns. The K2 further rduces suspended sediment of particles 2 microns or larger and protects the RO100S RO membrane. The latter serves as a long-lasting shield against any toxic substances, heavy metals, pesticides, bacteria, viruses and protozoa for 380 litres per day. Lastly, the K7BM further protects aginst smaller bacteria using hollow fibre membrane technology, removing particles larger than 0.1 micron, then enriches the water with magnesium and calcium HOW IT WORKS: The K5 & K2 prefiltration cartridges deliver the most effective filtration of coarse particles up to 3 microns like sand or clay and protection of the RO50S RO membrane. The latter serves as a long-lasting shield against any toxic substances, heavy metals, pesticides, bacteria, and viruses. HOW IT WORKS: Designed with CarbFiber Block technology, the replacement filter pre-treats the water by removing organic impurities, heavy metals and chlorine. It filters particles down to 5 micron in size and gives protection of the RO-50S RO membrane. The latter serves as a long-lasting shield against any toxic substances, heavy metals, pesticides, bacteria, and viruses. Review: A leak free RO under-sink Water Filter - Having tried twice before tried to install an under sink water filter, both of which leaked immediately after installation I went for the Aquaphor RO 101s. It has been in a month without leaking, provides pure drinking water due to the reverse osmosis system and is very compact. It does not require electricity to function and the filters are simple to change as it has a twist lock system. Highly recommended. Review: Perfect - One of the best filters and for a good price. Easy to install, No leak ## Features - INNOVATIVE TECHNOLOGY: The innovative RO-101S water tank takes up half the space under the sink than a traditional Reverse Osmosis system, saving up to 9,000 litres of water per year - and even works in houses water pressure at low as 1.9 bar of Dynamic Pressure. - WHATS IN THE BOX: The Aquaphor RO-101S system comes complete with a tap and 4 filters, 1 x K5 Pre-filter, 1x K2 treatment & filtration cartridge, 1 x R0-50S membrane cartridge and 1x K7M water conditioning and re-mineralisation cartridge. Replacement filters are available individually - or in convenient money saving multi-packs. - HOW IT WORKS: The K5 & K2 prefiltration cartridges use AQUALEN microfibre technology to filter out coarse particles like sand or clay - and the RO50S membrane eliminates bacteria, viruses, heavy metals,PFAS, microplastics, pesticides, lead, limescale, and chlorine. Finally, the K7M water conditioning and re-mineralisation cartridge adds back essential nutrients. - GREAT TASTING WATER WITH ESSENTIAL MINERALS RESTORED: Unlike basic RO systems that strip water flat, the RO-101S finishes with a K7M re-mineralisation stage — restoring the essential minerals for balanced, refreshing taste. Perfect for drinking straight, making baby formula, brewing coffee, or cooking. - LONGER APPLIANCE LIFE: RO-101 completely removes hardness from water, giving a longer life for coffee machines, kettles, irons and steamers - and means your humidifier will no longer leave a white dust on furniture. - SERVICE AND MAINTENANCE : AQUAPHOR recommend changing your cartridges once per year using the easy to do, click & turn cartridge replacement system. Replacement filters are available individually - or in convenient money saving multi-packs. - INSTALLATION : AQUAPHOR recommend engaging a plumber for the installation process - however, the AQUAPHOR RO-101S can be installed by a home owner competent in DIY. - REPLACEMENT CYCLE : AQUAPHOR recommend installing new filters every 12 months, and a new membrane every 24 months – however, if the taste of water output changes, please replace within this timeframe. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N4N1NUD | | Best Sellers Rank | 124,107 in DIY & Tools ( See Top 100 in DIY & Tools ) 84 in Under-Sink Filters | | Brand | AQUAPHOR | | Capacity | 5 litres | | Container Type | Faucet | | Country Of Origin | Estonia | | Customer Reviews | 3.8 out of 5 stars 69 Reviews | | Filter Life Cycle | 1 Years | | Included Components | Under Sink System | | Included components | Under Sink System | | Installation Type | Under Sink | | Item Dimensions L x W x H | 37L x 19W x 42H centimetres | | Item Weight | 7.4 Kilograms | | LowerTemperature Range | 5 Degrees Fahrenheit | | Manufacture Year | 2019 | | Manufacturer | AQUAPHOR | | Manufacturer Part Number | 508761 | | Material | Plastic | | Material Type | Plastic | | Maximum Flow Rate | 190 Litres Per Day | | Model Name | RO-101S | | Model Number | 101S | | Other Special Features of the Product | Remineralization | | Power Source | Corded Electric | | Product dimensions | 37L x 19W x 42H centimetres | | Purification Method | Reverse Osmosis | | Smart Home Compatibility | Not Smart Home Compatible | | Special feature | Remineralization | | Supported Water TDS Level Maximum (PPM) | 500 | | Unit Count | 1.0 count | | Upper Temperature Rating | 100 Degrees Celsius | ## Product Details - **Brand:** AQUAPHOR - **Capacity:** 5 litres - **Included components:** Under Sink System - **Installation type:** Under Sink - **Material:** Plastic - **Package information:** Faucet - **Power source:** Corded Electric - **Product dimensions:** 37L x 19W x 42H centimetres - **Purification method:** Reverse Osmosis - **Special feature:** Reverse Osmosis, Space-Saving Design, Remineralization ## Images ![RO-101S Compact Reverese Osmosis Under Sink Water Filtration System - 4 Stage Filter -Reduces Bacteria,Lead, PFAS, Heavy Metals,Chlorine and Limescale | Re-mineralises for better taste - Image 1](https://m.media-amazon.com/images/I/61QTlWkKBPL.jpg) ![RO-101S Compact Reverese Osmosis Under Sink Water Filtration System - 4 Stage Filter -Reduces Bacteria,Lead, PFAS, Heavy Metals,Chlorine and Limescale | Re-mineralises for better taste - Image 2](https://m.media-amazon.com/images/I/61uRjZ-+ndL.jpg) ![RO-101S Compact Reverese Osmosis Under Sink Water Filtration System - 4 Stage Filter -Reduces Bacteria,Lead, PFAS, Heavy Metals,Chlorine and Limescale | Re-mineralises for better taste - Image 3](https://m.media-amazon.com/images/I/81tCh1AjTuL.jpg) ![RO-101S Compact Reverese Osmosis Under Sink Water Filtration System - 4 Stage Filter -Reduces Bacteria,Lead, PFAS, Heavy Metals,Chlorine and Limescale | Re-mineralises for better taste - Image 4](https://m.media-amazon.com/images/I/81CBJJzz4CL.jpg) ![RO-101S Compact Reverese Osmosis Under Sink Water Filtration System - 4 Stage Filter -Reduces Bacteria,Lead, PFAS, Heavy Metals,Chlorine and Limescale | Re-mineralises for better taste - Image 5](https://m.media-amazon.com/images/I/71plPIS5jmL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A leak free RO under-sink Water Filter *by W***S on 13 July 2023* Having tried twice before tried to install an under sink water filter, both of which leaked immediately after installation I went for the Aquaphor RO 101s.
