About Rain Curtain Multifunctional Humidifier
Rain Curtain is a combined air purifier and humidifier designed for home use. Water is circulated and sprayed onto the humidification filter from above, which keeps the filter moist and improves humidification efficiency. The filter is separated from the water tank to reduce bacterial growth. A semi-transparent window, named the rain curtain, makes the flowing droplets visible during operation. Four air purification functions and five water sterilization functions are included. Rain Curtain is controlled through the front touch screen or a mobile application.
Within the evolving landscape of contemporary domestic technology design, Qierling Health iTech's Rain Curtain Multifunctional Humidifier emerges as a compelling synthesis of functional engineering and contemplative aesthetic experience, positioning itself within lineages of Scandinavian and East Asian design philosophies that privilege material restraint, geometric clarity, and the integration of natural phenomena into technological objects, the work achieves particular distinction through its novel transparent reservoir system where visible water circulation transforms utilitarian moisture dispersion into meditative visual spectacle, suggesting affinities with traditional water features and rain chains that have long occupied places of honor in contemplative garden traditions, the circular digital interface embedded within the pristine white facade references historical astronomical instruments and contemporary smart device conventions simultaneously, creating temporal bridges between ancient timekeeping traditions and twenty-first century connectivity expectations, technically the design demonstrates sophisticated understanding of visual hierarchy wherein the luminous water chamber commands initial attention before the eye descends to discover operational parameters displayed with typographic precision, the chromatic strategy of predominantly achromatic surfaces punctuated by cool blue illumination and warm amber indicators creates temperature contrast that enlivens the minimal palette without compromising overall serenity, material choices suggest ceramiclike durability while maintaining approachable domestic scale, the proportional system governing the relationship between transparent crown and opaque body suggests careful calibration to achieve visual balance between technological function and sculptural presence, one might consider how this object participates in broader cultural conversations regarding the aestheticization of wellness technology and the domestic integration of climate control systems that no longer hide their mechanisms but celebrate them as visual amenities, viewers are invited to contemplate how technological objects increasingly aspire to the contemplative qualities traditionally reserved for decorative arts and how the boundary between appliance and sculptural presence continues to evolve
Press Kit
- Unique Properties
- Traditional siphon mistless humidifiers can promote bacterial growth due to immersed cartridges. The company developed Living Water Circulating Spray Humidification Technology, which sprays water onto the cartridge from above, keeping it soaked and improving efficiency. The cartridge is separated from the water tank to minimize bacteria. The "rain screen" window visualizes the humidification process, with droplets flowing like "rain mist" on the transparent PP surface for a natural experience.

- Production Technology
- The company designed the "Rain Curtain" semi-transparent window to showcase its water circulation spray humidification technology, allowing users to see rainwater effects on glass. Emphasizing "less is more," the product's front was simplified, focusing on the round screen and transparent window. The air intake grille is cleverly hidden on the sides and back, while the square and round contours help it blend seamlessly into various home environments.
- Design Challenge
- Traditional siphon humidifiers use soaked filters, which can cause bacteria to grow in the water. Generally, if the filter is not soaked in water, the humidification efficiency may be reduced. To this end, the company has developed a live water circulation spray humidification technology that sprays water from above to the humidification filter to keep it moist at all times and improve humidification efficiency. The filter is separated from the water tank to reduce bacterial growth.
- Project Duration
- The project officially started in Beijing, China in March 2023 and will be completed and listed in China in October 2024.
- Operation Flow
- Users can control the product via the "Smart Life" app or the front touch screen, allowing them to set fan speeds, humidity levels, and switch between preset modes. The screen will prompt users to clean the filter when it is exhausted. When the top circular screen shows "00%" for the water tank, users can easily fill it with tap water through the top port. The water tank includes five levels of antibacterial technology to purify the water at the source.
- Research
- This product uses living water circulation spray technology, delivering 1200ml/h of humidification for spaces up to 120 square meters. The 6L water tank allows for 19 hours of continuous use. With a particle CADR of 400, it purifies areas up to 48 square meters. It features a dynamic humidity algorithm for intelligent adjustments, preset modes, and an automatic air-drying function. It also monitors temperature for optimal humidity and includes a sleep mode for added comfort.
- Inspiration
- The 720 Air Purifier Humidifier features active water circulation spray technology, directing water to the top of the cartridge for downward spraying. This design separates the cartridge from the water tank, minimizing bacterial growth. It includes four air purification and five water anti-bacterial functions for fresh air. The "rain curtain" translucent window showcases the technology, simulating rain on glass for a soothing humidification experience.
