Quiet on one side, cat-oriented design on the other. The KI-RS50 idles at 17 dB, among the quietest here, but covers only 38 m², has neither app nor pet mode, and SHARP publishes no CADR. The Core 400S states 45 m² and 400 CADR, includes both app control and a pet mode, and costs less. Pick the KI-RS50 if bedroom silence comes first; pick the Core 400S to choose on published numbers for hair and odour.
