## What reviewers say

Only one whitelisted tester produced verifiable readable review text: Tom's Guide, whose hands-on (not lab) review calls the Core 400S the 'ideal air purifier' - stylish, quiet, and fun to use, clearing stovetop smoke in about 10 minutes. The reviewer explicitly states Tom's Guide could not scientifically lab-test the filtration claims, so no measured lab data is available. (Based on 1 review, 2021-08-02.)

Praised: Sleek, futuristic minimalist cylinder design that looks nice in a living room; Quiet, easy to set up, clean and carry; Responsive auto mode that ramped up and cleared stovetop smoke fast; Fun real-time laser PM2.5 air-quality readout plus capable VeSync app with scheduling and graphs.
Flagged: Replacement filters cost ~$50 and may need swapping as often as every 6 months, adding up over time; Voice-assistant control was hit-or-miss; easier to just use the app; Filtration/HEPA claims unverified - reviewer could not scientifically lab-test them.
Disagreement: No cross-source comparison is possible: only one whitelisted source (Tom's Guide) produced verifiable review text. Its verdict is uniformly positive but is explicitly a hands-on impression rather than a lab-measured evaluation.
