Package List
Disclaimers
*Whole-home, room-wide, full coverage: Tested by a third-party lab in a 2,860 ft³ chamber, Report No.: KH-IR-202402224. Actual results may vary by room size, layout, and ventilation.
*Mist-free Evaporative Technology: A humidification technology that increases air humidity through water evaporation without generating visible mist. Provides a more uniform and safer increase in humidity.
*Filters minerals: Converts water into water molecules through evaporation, avoiding the white mist generated by traditional ultrasonic humidifiers.
*27 fl oz/h: Tested by third-party laboratory. Report No.: WTS2025-18841-1.
*8 minutes: Tested by third-party laboratory. The sample unit was placed at the center of a 1,060 ft³ test chamber, with initial temperature and humidity set at 73.4±3.6°F and 30±5% RH. At maximum setting, the time recorded for humidity to rise from 30% to 50% was 8 minutes. Report No.: 20250819-001.
*Three-stage Purification: The product is equipped with a high-efficiency composite filter for air-duct purification, plus a phosphate-based anti-scale agent, and a 3D washable antibacterial filter for dual water-system purification, thereby achieving four-stage purification for both the air duct and water systems.
*Viruses: Determined according to ISO 18184:2014(E) standard by a certified testing organization. The filter material shows antiviral effects on influenza A virus (H1N1). Report No.: 2020FM15750R01.
*Bacteria: Tested by third-party laboratory. Our filter material provides antibacterial protection against Escherichia coli, Staphylococcus aureus, Serratia marcescens, and Legionella pneumophila. Report No.: 2019FM10578R01, 2019FM10616R01.
*Particulate matter: Based on tests in our in-house lab. Our filter material provides effective filtration of pet hair, dust, and particulate matter as small as 0.000012 in, Report No.: AZW-QR-RDC-A0.
*Reduced limescale in water tank: Tested by third-party laboratory. Tests showed that 0.18 oz of anti-scale agent achieved a scale inhibition rate of up to 96% in 462 gallons of flowing water; in the static water tank of a humidifier, the effect is even better. The product contains 0.71 oz of anti-scale agent in total, with no need for replacement or repurchase during its entire lifecycle. Report No.: H2302888.
*Mold prevention: Indicates that the 3D washable antibacterial filter achieved grade 0 in mold resistance performance. The test was conducted in a third-party laboratory by placing the sample material under 90% RH and 82.4°F, using mold species including Aspergillus niger, Aspergillus terreus, Penicillium variabile, Penicillium funiculosum, Chaetomium globosum, and Scopulariopsis brevicaulis. No mold growth was detected within 28 days, thus rated as grade 0. Report No.: WJ20233668.
*Safe antibacterial: Tested by third-party laboratory. The filter material demonstrates antibacterial effects against Escherichia coli, Staphylococcus aureus, Candida albicans, and Staphylococcus albus. Report No.: WJ20233505.
*It is recommended to clean the filter once a week to maintain efficient humidification.
*24 hours: In laboratory conditions, with a full 1.6-gallon tank and operating at 8.5 fl oz/h humidification setting, the usage time can reach up to 24 hours. The data is for reference only. The actual usage time may vary.
*0.6 kWh: 24 W * 24 h = 0.576 kWh, 1 kWh = 1000 Wh
*It is recommended to empty the water tank after each use and activate the air-dry mode to extend the service life of the evaporation filter.
*The illustrations in this manual are for reference only. Please refer to the actual product.
*All data is based on lab data. Actual performance may vary.
