Verdict

The Airthings Renew is a smart, minimalist air purifier designed for rooms up to 525 sq ft, offering a clean air delivery rate (CADR) of 140 CFM through a 4-stage filtration system. This setup features a textile outer pre-filter, a washable inner mesh pre-filter, a medical-grade HEPA-13 filter that captures 99.97% of particles down to 0.3 microns, and an active charcoal filter to mitigate volatile organic compounds (VOCs) and odors. Key pros include its versatile floor-standing or wall-mountable design, an ultra-quiet 23 dB Silent mode ideal for bedrooms, an automated Auto mode guided by a high-precision laser PM2.5 sensor, and smartphone app connectivity. However, notable cons include its high retail price, expensive filter replacements, basic on-device display lacking exact numerical PM2.5 readings, and a lack of native integration with popular smart home platforms like Amazon Alexa, Google Assistant, or Apple HomeKit.
