## At a glance

- Five filtration stages include three pre-filters, an RO membrane and a final polishing filter, according to the listing.
- A 3.2-gallon storage tank provides a reserve of filtered water.
- The listing describes a transparent first-stage housing for visual filter inspection.
- The manufacturer says the system is intended for municipal tap water, not untreated well water.

## Pros

- No electrical power source is required according to the listed power configuration.
- The included black faucet provides a separate dispensing point for treated water.

Confirm the exact certification scope for the complete system and components if certification is a purchase requirement.
