## Verdict

CNET's best overall for balanced performance, held back one slot by HouseFresh's finding that its thin carbon makes it weak on odors and VOCs.

## For

- The most balanced overall performance in CNET's lab testing
- Excellent particle removal
- Named CNET's best overall air purifier
- Good air cleaning performance at top speed per HouseFresh
- Strong large-room performance; CNET's best bet for larger spaces

## Against

- Lacks pelleted activated carbon, making it pretty useless for VOCs and chemical gases
- Genuine filters are pricier than Coway/Winix equivalents
- Nudges app registration and filter-subscription upsells

## 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.
