## Verdict

Tank simplicity, cheap universal filters and a support record that has held for a decade. The dependable budget anchor.

## For

- Six stages of filtration
- Large storage tank
- Standard-sized filters with a huge aftermarket
- Water quality rivaling pricier options
- Water tastes as good as from far costlier systems

## Against

- Dated efficiency versus modern systems
- A tester's water analysis found it introducing contaminants the feed water did not contain
- The RCC7AK beats it on ergonomics and adds remineralization for similar money
- Legacy tank-based 5-stage design
- Poor water efficiency compared with modern tankless systems

## Flagged as one to avoid

This product entered 2 of 12 runs as one buyers cross-shop but should not buy, rather than as a pick. It is published here rather than dropped.

## What this tier means

- A: Excellent. Strongly recommended, beaten only by the very best.

## How to read this

- Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.
- LP is this product's points on its own category ladder. It is comparable within a category and not across categories.
- Link status reports what our pre-publication link check found when it fetched the cited URL. It says nothing about the quality of the review.
- A citation with no usable link is listed rather than dropped, and is excluded from the counted total above.
