Overview
The iSpring RCC7AK-UV is an under-sink reverse osmosis system rated to produce 75 gallons per day, adding a UV disinfection stage to the RO membrane in a unit measuring about 15 x 8 x 18 inches and weighing 20 pounds.
Under-sink RO systems mount below the kitchen sink and typically feed a dedicated faucet, trading pitcher-level simplicity for a multi-stage setup that needs drain and supply line connections. The UV stage here layers disinfection on top of the RO membrane, a step beyond the plain carbon filtration used in pitchers and inline fridge filters.
- Reverse osmosis filtration with UV stage
- 75 gallons per day rated capacity
- Under-sink install format
- 15 x 8 x 18 in, 20 lb unit
Who it's for
Suited to households wanting whole-kitchen RO-filtered water on tap and willing to do, or pay for, an under-sink installation. Not a fit for renters or anyone wanting a filter with zero installation, like a pitcher or fridge cartridge.
Strengths and trade-offs
Drawn from this product's published specifications.
- 75 gallon per day rated output
- Adds UV disinfection on top of RO filtration
- Requires under-sink installation with supply and drain connections
- 20 lb unit needs dedicated cabinet space
Performance notes
Reverse osmosis forces water through a semi-permeable membrane to remove dissolved contaminants, and the added UV stage is meant to address microorganisms an RO membrane alone may not fully catch, at a rated output of 75 gallons per day.
