Between the HPA300 and Core 600S, the HPA300 comes out ahead in several specs, while the Core 600S wins on coverage and cadr. Overall, the HPA300 scores 65 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 12.4 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 HPA300 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, min noise.
Both ship with comparable true hepa h13+, activated carbon, 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.
