This is the top of the tank-based range and makes sense for a well household that also wants mineral taste restored, which is a narrow but real buyer. Stacking UV and remineralisation costs ninety-two dollars over the plain RO10 and adds no footprint, which is the genuinely clever part of the design. Against that, it inherits every weakness of the platform and adds two: a mains outlet requirement and two extra consumables on separate schedules. Neither added stage carries certification - no NSF/ANSI 55 for the UV and no published dose, no verification of mineral output for the alkaline cartridge - so the buyer is trusting Express Water on both. The trade here is convenience and taste against maintenance count and unverified claims.
- Both UV sterilisation and remineralisation without any increase in footprint or weight
- Sensible combination for private wells where flat RO taste is also a complaint
- Shares cartridges and housings with the rest of the range
- Leak-detection pad and clear first-stage housing included
- Ninety-two dollars for two stages is cheaper than buying either as an upgrade kit
- No NSF listing, no NSF/ANSI 55 for the UV stage, no published UV dose
- Mineral output is reported to fall off across cartridge life with no published range
- Seven consumables on two different replacement schedules
- Requires a mains outlet under the sink
- One-year warranty
- 50-100 GPD production, slow for the money in 2026
The ROALKUV10 combines both optional Express Water stages on one chassis: a 12-16 W ultraviolet lamp after the membrane and an Active Mineral Technology remineralisation cartridge after that. Production is 50-100 GPD into a 4-gallon tank holding about 3.2 gallons usable, with a 0.8 GPM faucet. Weight and footprint are identical to the base system despite the two extra stages.
