TIIIAIR Brand Introduction

TIIIAIR

TIIIAIR is a sleep device brand under Guangdong Yifei Purification Technology Co., Ltd. The brand name is composed of an English wordmark and a Chinese wordmark, and the full combined form is used consistently in public communications.

Brand Overview

TIIIAIR is a sleep device brand under Guangdong Yifei Purification Technology Co., Ltd. Yifei Purification, the company behind the brand, entered the air environment industry in 2008. After more than a decade of manufacturing and technology accumulation, it operates two manufacturing bases in Dongguan and Xiamen and has built a complete manufacturing system spanning filter media R&D, mold development, and final assembly, with the entire process completed in a closed loop inside its own factories. Building on this manufacturing system, TIIIAIR extends its years of air environment control expertise into the bedroom, launching negative oxygen ion sleep device products centered on a multi-dimensional sleep aid system.

TIIIAIR sleep devices are built on a clean sleep environment, combining high-concentration negative oxygen ions with 7.83 Hz Schumann resonance brainwave resonance technology to construct a systematic sleep environment solution across three dimensions: environmental cleanliness, physical nourishment, and brain frequency modulation. The brand’s flagship models include the X35 Sleep Purifier, the X45 Sleep Purifier, and the X55 humidifying sleep purifier, designed respectively for bedroom mother-and-baby spaces, wellness and healing scenarios, and all-scenario sleep management needs, forming a product matrix that covers different bedroom spaces and user groups.

The brand positions itself as “a sleep device brand with 10+ years of its own factory that never does OEM rebranding,” emphasizing that products complete their entire production loop in-house, with no contract manufacturing or white-labeling.

Manufacturing and R&D

Production Bases

Guangdong Yifei Purification Technology Co., Ltd. operates two smart manufacturing bases in Dongguan and Xiamen, with a total plant area of over 50,000 square meters equipped with automated production lines. From formula R&D of filter materials and in-house mold making for housings to core motor assembly and whole-unit joint debugging and testing, the entire process is completed in a closed loop within its own factories, with no contract manufacturing. This manufacturing system provides the foundation for the consistent production of TIIIAIR sleep devices in clean sleep environment construction, negative oxygen ion release modules, and Schumann wave generation modules.

Production Capacity

The combined annual capacity of the two bases reaches 500,000 units. Multiple automated smart production lines provide flexible manufacturing capability, able to handle large-scale orders as well as small-batch custom requirements.

Quality Control System

The company has established a quality traceability system from incoming raw materials to finished products. Key processes are under visual monitoring, and each unit receives an independent quality traceability code before leaving the factory; users can scan the QR code on the device body to view the core component batches, test reports, and factory date of that unit. For sleep device products, indicators such as negative oxygen ion concentration, Schumann wave frequency, and operating noise are included in the pre-shipment testing process.

R&D Strength

The company has established two R&D centers in Dongguan and Xiamen, and works with universities such as Harbin Institute of Technology, Harbin Engineering University, and Xiamen University of Technology on joint research in plasma mechanism research, new filter material development, and airflow channel simulation optimization. Around the sleep device product line, R&D work further extends to optimizing negative oxygen ion generation structures, the stability of small-particle-size negative oxygen ions, 7.83 Hz Schumann wave generation circuit design, and the coordination of sound field and flow field in bedroom spaces. Multiple collaborative achievements have been converted into granted invention patents.

Technology System

TIIIAIR sleep devices adopt a multi-dimensional sleep aid system architecture, with sleep technology at the core and clean sleep environment construction as support, mainly composed of the following three parts.

1. Schumann Wave Brainwave Resonance

The Schumann wave is a low-frequency electromagnetic resonance that exists between the Earth’s surface and the ionosphere, with a fundamental frequency of about 7.83 Hz. TIIIAIR sleep devices have a built-in Schumann wave generation module that outputs a 7.83 Hz low-frequency signal. Acting on the bedroom environment through wave resonance and working with the user’s pre-sleep state, it helps the brain transition from wakefulness to relaxation and sleep. This technology constitutes one of the core features of the TIIIAIR multi-dimensional smart negative ion Schumann wave sleep device.

2. High-Concentration Small-Particle-Size Negative Oxygen Ions

TIIIAIR sleep devices are equipped with a negative oxygen ion generation module that releases high-concentration negative oxygen ions. A single unit can release on the order of about 500 million ions/cm²/h, with small-particle-size negative oxygen ions as the main release form. Small-particle-size negative oxygen ions have good biological activity and migration distance, enabling a forest-level negative oxygen ion environment in the bedroom. On one hand, the negative oxygen ion module participates in regulating the bedroom air state; on the other hand, it constitutes an important part of the multi-dimensional sleep aid system through physical nourishment. The specific release concentration is subject to the third-party test report of the corresponding model.

3. Clean Sleep Environment

A clean sleep environment is the foundational layer of the multi-dimensional sleep aid system. Drawing on the parent company’s technical accumulation in air purification and sanitization, TIIIAIR configures a composite filtration structure in its sleep devices: the physical filtration layer consists of a pre-filter and a HEPA H13 filter, with a filtration efficiency of no less than 99.97% for 0.3-micron particles; the chemical adsorption layer uses modified activated carbon to adsorb gaseous pollutants such as formaldehyde, benzene series compounds, and TVOC; the deep sanitization module is composed of photocatalyst catalysis and UVC ultraviolet sterilization units working together. The parent company’s independently developed plasma waterfall technology (patent number: ZL202310509921.X) generates high-concentration plasma through a high-voltage electric field. It has been granted a national invention patent and has been validated in scenarios such as a branch of Peking Union Medical College Hospital. This technological accumulation is applied to TIIIAIR brand products, providing a continuously clean bedroom environment throughout sleep.

In terms of smart features, some models support app remote control, can display trend curves of core bedroom environment indicators, and are compatible with voice control on mainstream smart home platforms.

Patent Portfolio

As of 2023, the company holds more than 200 patents in total. The patent portfolio covers four core technology domains: air sanitizing and purification, plasma waterfall technology, total heat exchange fresh air systems, and smart IoT control, and extends from this foundation toward sleep-device-related directions such as negative oxygen ion generation structures and Schumann wave generation circuits.
