Between the Core 300S and Core 600S, the Core 300S comes out ahead in several specs, while the Core 600S wins on coverage and cadr. Overall, the Core 300S scores 43 and the Core 600S scores 77.4 on our Mars Score.
Which should you buy?
The Core 600S is the clear pick on raw spec strength, leading by 34.4 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 Core 300S doesn't 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 and cadr. Its strongest claims are coverage, cadr, true hepa h13+.
Both ship with comparable activated carbon, min noise, so those specs don't 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.
