Continuous Plug-In Air Freshening for Localized Odor & Smoke Control

The KINYO KYHC04 is a direct wall-socket mini negative ion air purifier engineered for localized continuous air treatment across residential bathrooms, commercial restrooms, hotel suites, kitchens, and pet environments. Utilizing an integrated solid-state high-voltage generator and precision carbon-fiber emission tip, the KYHC04 dispenses over 34 million negative ions per cubic centimeter. The high-density anion stream binds with positively charged airborne dust, particulate matter, and secondhand cigarette smoke to precipitate them out of breathing zones while rapidly degrading persistent ambient odors—all without replacement filters, bulky cords, or motorized noise.

Performance & Verification

Parameter Result / Accuracy Notes
Negative Ion Emission Density > 34.0 × 10⁶ pcs/cm³ Internal Laboratory Test
Deodorization & Smoke Removal Rate > 90.0% Internal Laboratory Test
High-Voltage Generator Output -1.6 kV to -10.0 kV DC Verified Internal Engineering Specification
Ozone Safety Boundary < 0.1 ppm Internal Laboratory Test
Operating Power Consumption 0.5 W (±10%) Verified Internal Engineering Specification
Operating Acoustic Noise 0 dB(A) (Solid-State Convection) Verified Internal Engineering Specification

Note: Performance results were obtained under controlled laboratory conditions. Actual performance may vary depending on test conditions, airflow, pollutant concentration and installation environment. Test reports are available upon request.

Engineering Highlights

01. High-Density Anion Dispersion

Solid-state emitter generates >34 million negative ions/cm³, binding with microscopic airborne dust, cigarette smoke, and allergens to precipitate them from breathing zones.

02. 0.5W Ultra-Low Power Draw

Optimized high-efficiency driver circuit consumes only 0.5 Watts of electricity, allowing cost-effective 24/7/365 continuous plug-in operation without thermal buildup.

03. 100% Filter-Free Architecture

Eliminates periodic HEPA or carbon replacement cartridges entirely, providing a true zero-maintenance, zero-consumable purification solution for facility operators.

04. Direct Wall Socket Integration

Compact wall-plug chassis available in US and EU configurations docks directly into wall outlets, freeing desktop surfaces and eliminating hazardous dangling power cords.
