## Verdict

Certified and genuinely effective TDS removal, but the most expensive filters in the class to keep running, which is why it ranks below the Culligan-branded ZD-012-RP.

## For

- NSF certified
- Removes 100% of magnesium and sodium and 99-100% of calcium
- Ready-Pour dispensing design
- Drops TDS to zero, confirmed in hands-on review
- Ready-Pour spigot is genuinely useful

## Against

- Ongoing filter cost is the highest in the class, eroding the value case over a year of use
- Strips beneficial minerals along with contaminants
- Burns through filters fast
- High filter replacement cost

## What this tier means

- S: Exceptional. Finishes top run after run; capped at 3 slots per category.

## 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.
