Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Honeywell - HPA300 | Levoit - Core 600S |
|---|---|---|
| Coverage | 44 m² | 60 m² |
| CADR | 510 m³/h | 680 m³/h |
| Min noise | 32 dB | 24 dB |
Between the HPA300 and Core 600S, the HPA300 comes out ahead in several specs, while the Core 600S wins on coverage / cadr. Overall, the HPA300 scores 74.4 and the Core 600S scores 83.9 on our Mars Score.
Which should you buy?
The Core 600S is the clear pick on raw spec strength, leading by 9.5 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
The HPA300 does not pull ahead on any single popular-comparison spec — its strengths sit in the spec-table groups rather than the headline advantages.
Pick the Core 600S if you care most about coverage / cadr. Its strongest claims are coverage, cadr, min noise. The single most decisive one: Coverage — 36.36% more. 60 m² vs 44 m².
Both ship with comparable true hepa h13+, activated carbon, so those specs do not separate the two — focus on the differences below.
Bottom line: the Core 600S is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
