LEVOIT Core 600S-P Smart True HEPA Air Purifier

Carbon filter quantity is a deal-breaker — Levoit doesn't publish carbon weight for any Core series model

You want the smallest room-to-CADR mismatch — the 0.645 ratio is slightly below AHAM's 2/3 minimum for the stated 606 sq ft

You need explicit H13 grade certification — True HEPA without H13 means the grade isn't independently certified at that standard

Housing material transparency matters — Levoit does not disclose plastic type or BPA-free status
