More Than Filtration: A Complete Under-Sink Water Experience

The HisoAir Under-Sink Cold & Sparkling Water System integrates water filtration, compressor cooling and carbonation into one compact product platform.

Users can access ambient, chilled or sparkling water through one multi-function faucet, while the main appliance remains installed beneath the sink to help keep the countertop clear.

The modular architecture can be adapted for residential kitchens, premium apartments, office beverage areas, hospitality projects and branded healthy-home product portfolios.

Three Water Options from One Smart Faucet

Users can select ambient, chilled or sparkling water through the integrated faucet interface. The light-ring display provides visual feedback for the selected dispensing mode.

Compressor Cooling for Consistent Chilled Water

The system uses compressor refrigeration to provide faster cooling and more stable chilled-water performance for regular household and light-commercial use.

Rated refrigeration capacity of approximately 1 gallon per hour
Approximately 0.75-gallon chilled-water storage tank
Target chilled-water temperature of approximately 3°C
Approximately 0.75 gallon of continuous water below 7°C under specified conditions
Automatic cooling activation according to detected water temperature

Actual performance depends on inlet-water temperature, ambient conditions, dispensing frequency and final product configuration.

Integrated Sparkling Water Module

The carbonation module is integrated into the under-sink platform, eliminating the need for a separate countertop sparkling-water appliance. Water can be chilled before carbonation to support a more consistent dispensing experience.

Water flow process through filtration cooling carbonation and smart faucet modules

Integrated Architecture Cooling and carbonation modules are contained beneath the sink.

Chilled Before Carbonation The water path can be configured to cool water before adding carbonation.

Configurable Modules Product combinations can be selected according to market positioning.

Multi-Layer Composite Filtration

The quick-change cartridge combines several filtration materials in one compact structure to reduce sediment, residual chlorine, unwanted odors and compounds that may affect water taste.

1. Pleated Pre-Filter Layer Reference filtration accuracy: 10–15 microns

2. Charged Membrane Layer Reference filtration accuracy: 1–5 microns

3. Carbon Block Layer Reference filtration accuracy: 0.5–1 micron

Final contaminant-reduction claims must be supported by test reports or certifications applicable to the exact cartridge and final product model.

Water-Break Quick-Change Cartridge

The cartridge uses a twist-lock replacement structure with an integrated water-stop mechanism. When the cartridge is rotated and removed, the internal valves are designed to close the water path and help reduce uncontrolled water discharge.

01 Rotate the cartridge approximately 90 degrees.

02 Unlock and remove the used cartridge.

03 Insert and lock the replacement cartridge.

04 Flush according to the operating instructions.

Modular Architecture for Different Product Strategies

Brands can select different combinations of cooling, filtration and carbonation according to their intended market, price positioning and user requirements.
