Yes. Every MistAirHome ultrasonic humidifier ships with CE, FCC, RoHS, UKCA, ETL, REACH, MSDS and ISO 9001 documents. The certificates are issued by TUV Rheinland, SGS and Intertek, and a fresh test report is included with each production batch. Compliance covers EMC per EN 55014-1, RF per EN 300 328, electrical safety per EN 60335-2-98, and BPA-free per EU 10/2011.
The WH-100 to WH-900 lineup covers noise levels from 23 dB on the WH-500 whisper-quiet sleep unit to 35 dB on the WH-900 commercial unit, verified in IEC 60704 anechoic chambers. Humidistat accuracy is +/-3%RH across the 30 to 80 %RH range, calibrated against Rotronic HygroClip reference probes.
Tank capacity runs from 300 mL on the pocket WH-100 to 12 L on the commercial WH-900. Runtime per fill ranges from 8 hours on the WH-100 to 60 hours on the WH-900. Top-fill design on WH-300 to WH-900 allows 5-minute tank cleaning with no spillage. Anti-bacterial BPA-free tank material reduces biofilm buildup, and we recommend monthly demineralization cartridge replacement.
Levoit, Honeywell and DREO retail brands command premium retail pricing and rarely accept OEM/ODM orders under 5000 units. Pure Enrichment and TaoTronics offer solid firmware but their OEM flexibility is limited and unit costs are 35-55% higher than factory-direct pricing. MistAirHome ships with full certification, OEM from 1500 units and 24-month warranty at factory-direct price.
