Source: dreo.com (verified 2026-07-07) · corroborated by amazon.com. VERIFIED 2026-07-07 (re-fetched and re-confirmed 2026-07-10). The official Dreo product page (title "Smart Humidifier 524S 6L", "HM524S User Manual") confirms a 6 L water tank, 60-hour autonomy, 28 dB operation, "Operation Mode: Ultrasonic", "Easy Top-Fill", and Wi-Fi smart control (a "Smart WiFi" variant; DREO app, Google Home, Amazon Alexa); its Specifications table states "Floor Area: 500 Square Feet" (the site nav teaser card's "550 ft²" was disregarded in favor of the authoritative spec table, which Amazon's spec table corroborates at 500). The Amazon US listing (DREO Store, "Model Name HM524S") corroborates every headline spec verbatim: Capacity 6 liters, Floor Area 500 Square Feet, Runtime 60 hours, 28dB Ultra-Quiet Operation, Easy Top-Fill design, Operation Mode Ultrasonic. Exact model HM524S confirmed on both pages (not the non-smart HM524 sibling nor 512S/713S/717S variants). Price: the Dreo store shows "Sale price $69.99 USD" during its Summer Chill Sale with no regular MSRP displayed, while the Amazon page rendered EUR 61.25 for German delivery, so no independent USD MSRP was captured. No release date is stated on either fetched page (Amazon lists only "Manufacture Year 2024", not a release date), so releaseDate is null.
