## Verdict

Unvalidated core technology and a bankrupt manufacturer: the single worst ownership bet in the category. Avoid at any price.

## For

- Premium, design-forward positioning
- PECO technology marketed as a differentiator from standard HEPA

## Against

- PECO technology never validated in independent testing
- Wirecutter's testing found its particle removal mediocre
- Company filed for Chapter 11 bankruptcy, leaving warranty support, app maintenance, and proprietary filter supply in limbo
- A premium-priced purifier whose manufacturer may not exist to sell you filters

## Flagged as one to avoid

This product entered 3 of 8 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

- F: Avoid. The evidence points you elsewhere.

## 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.
