Overview
The iSpring RCC7U is a reverse osmosis filtration system rated for 75 gallons, built with a metal housing and set up as a DIY do-it-yourself install for under sink use.
This is a self install reverse osmosis system rather than a professionally fitted or countertop unit, aimed at buyers comfortable connecting their own under sink plumbing. The 75 gallon rating is lower than some other listed systems, pointing to more frequent filter changes.

- 75 gallon capacity
- DIY install type
- Metal construction, 28 lb
Who it's for
Fits homeowners comfortable with a DIY under sink install who want reverse osmosis filtration on a budget. Renters or anyone unwilling to do their own plumbing work should look at a countertop RO unit instead.
Pros and cons
- Reverse osmosis filtration
- Metal housing for under sink installation
- DIY install keeps cost down versus professional fitting
- 75 gallon capacity means more frequent filter changes
- Requires comfort with DIY plumbing work
- At 28 lb, sizing for under sink space should be checked
Performance notes
Reverse osmosis filtration through a semi permeable membrane targets a broad range of dissolved contaminants, and the metal housing is built for a fixed under sink placement. A 75 gallon capacity rating is on the lower side, so expect more frequent filter changes than the higher capacity systems in this category.
