## Verdict

The Guardian's best overall, with the performance to match, but a meaningful slice of its price buys design rather than clean air, so it sits below the value picks.

## For

- Named 'Best air purifier overall' in The Guardian's 2026 UK testing
- Measured performance keeps it competitive with dedicated air cleaners
- Premium design and finish
- RTINGS' best air purifier for pets (tested)
- Very high overall performance with whisper-quiet operation

## Against

- Part of what you pay for is design and finish rather than clean-air delivery

## What this tier means

- B: Good. A solid choice with real caveats worth knowing.

## 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.
