TL;DR
Both purifiers are AHAM VERIFIDE and suit allergy sufferers in large rooms but cater to different buyers: the KNKA Air Purifier for Home covers up to 1,695 sq ft per hour and includes a live AQI display, making it the better option for open-plan spaces where real-time air feedback matters. The LEVOIT Air Purifiers for Home offers a slightly larger coverage of up to 1,875 sq ft/hr, adds smart Wi-Fi control, and measures just 15.6 × 8.5 × 19.8 in, making it easier to fit into smaller areas. The KNKA’s biggest drawback is a higher price point and not confirmed in the sources checked for this update dimensions, while the LEVOIT lacks documented CADR figures.
