Joos-Tech Corporation (Headquarters: Minato-ku, Tokyo) will launch the popular model 'Ultra S7,' which has garnered strong support in the Taiwanese market, under the air purifier brand 'Apolnus' in the Japanese market in mid-April 2026.
While typical air purifiers mainly focus on capturing particles between 0.3 and 0.1 μm, the Ultra S7 is designed to capture ultra-fine particles as small as 0.003 μm—equivalent to just 1/800th of PM2.5, which is about 100 times finer.
This model reflects the brand's unique technological prowess, significantly enhancing purification performance to areas that were difficult for conventional air purifiers to address.
Since its launch in Taiwan, the Ultra S7 has steadily gained support from consumers who prioritize allergy care and quality of living environment. It features a minimalist and sophisticated design, balancing high air purification capabilities with a compact size, and proposes a new standard of air purification for Japanese consumers seeking a cleaner indoor environment, including households with infants or pets.
**Evolution of Purification Technology – Beyond the "0.3μm Barrier"**
In recent years, the indoor air environment has become increasingly complex, requiring responses not only to PM2.5 and pollen but also to virus-derived microparticles and ultra-fine allergens—invisible 'extremely small risks'.
Typical viruses are about 0.1 μm in size, or even smaller depending on the type. Filters based on the conventional standard of 0.3-0.1 μm could potentially allow these fine particles to pass through, posing a significant challenge for thorough air management.
Apolnus focused on breaking through this '0.3 μm barrier'.
**Captures Fine Particles Down to 0.003μm**
The Ultra S7 successfully enhances its collection performance to the 0.003 μm level by adopting an H13 class high-performance filter. This enables the capture of ultra-fine particles down to 0.1 μm class and virus-derived airborne substances that conventional air purifiers could not trap.
This goes beyond simply circulating air; by physically removing invisible fine threats, it elevates the air in your home from being 'regulated' to being 'protected'.
**Real-time Detection with High-Sensitivity VOC Sensor**
Indoor air is constantly changing in various daily situations, from cooking and cleaning to emissions from new furniture.
However, many of these changes are invisible, and by the time you notice them by sensation, you may have already been exposed for a long time.
The Ultra S7 is equipped with a high-sensitivity VOC odor sensor, allowing it to detect subtle changes in odors and volatile organic compounds (VOCs) in real-time.
**Deodorization Performance to Improve Air Environment in a Short Time**
When the sensor detects changes in the air, the multi-layer filter system, including an activated carbon filter, responds quickly.
With an air circulation capacity that belies its compact size, it has been confirmed to reduce various household odors such as cooking fumes, VOCs, and pet odors by 99.9% in about 4 minutes.
It demonstrates its effectiveness even in situations where you want to quickly improve the air, such as before guests arrive or after cooking.
*Results from a sealed test environment; not validated in actual usage. Effects may vary depending on the usage environment and room conditions.
**Air Quality at a Glance – 3-Color LED Display**
The air quality detected by the sensor is displayed in real-time using a 3-color LED lamp (red, yellow, blue).
This eliminates the invisible anxiety of 'Is the air clean or dirty right now?' and allows you to intuitively grasp the timing for ventilation or air purification. By 'visualizing' the air quality, it supports the creation of a comfortable living environment at all times.
**Maintaining Performance for Longer – Durable and Hygienic Design with High-Density Filter**
It is generally understood that HEPA filters can become clogged with dust and cooking fumes over time, leading to a decrease in collection performance.
The Ultra S7 uses a multi-layer filter with a high-density and long-life design, allowing it to stably capture fine particles over extended periods.
Furthermore, by incorporating an antibacterial film layer, it suppresses the growth of bacteria and mold inside the filter, making it easier to maintain a clean state.
Thanks to this durable design, the filter replacement interval is approximately 12 months. Compared to models requiring replacement every three months, this can reduce consumable costs by about 75%.
The lower frequency of replacements also contributes to waste reduction, allowing for a design that easily balances high purification performance with environmental consideration in daily life.
**Quiet Operation of Approximately 19dB, Compatible with High Purification Performance**
The Ultra S7 achieves a quiet operation of approximately 19 dB. Its airflow structure, designed to enhance air current stability, enables quiet operation with minimized vibration.
It can be used comfortably without worrying about noise, even in spaces with napping babies or during evening hours for reading or working.
**Remote Operation via Smartphone Connectivity**
In line with modern lifestyles, the Ultra S7 supports smartphone connectivity features.
Through a dedicated app, you can check the indoor air quality, operating status, and filter maintenance notifications at any time from your smartphone, and operate it with a single touch even when you are away from home.
Furthermore, it supports voice control, allowing you to operate it solely by voice even when your hands are occupied with chores or work, making it easy to maintain a comfortable air environment.
**Compact Size, Capable of Handling Large Spaces**
Despite its compact size of only 31cm in height, it possesses air purification capabilities suitable for spaces up to 16 tatami mats (approximately 26 square meters).
Going beyond the typical constraint of being exclusive to small rooms, it demonstrates its performance in various spaces, from living rooms to bedrooms.
**Design that Blends Naturally with Interiors**
With a matte finish and a clean cylindrical form, it minimizes its presence as an appliance, designed to blend naturally into any space, whether it's an entryway, bedside, or desk area.
**Lightweight Design for Flexible Use According to Your Lifestyle**
The main unit weighs approximately 1.95 kg. Its light weight, allowing it to be held with one hand, means you can easily move it between rooms without being fixed to one location.
From the living room where you spend time with pets during the day to the bedroom at night, it's designed for flexible use according to the flow of your life and scenes.
**Commitment to Quality and Safety**
Apolnus is designed under strict quality control from development to manufacturing, complying with various standards such as SGS testing, PSE, and TELEC. Based on confidence in its proprietary technologies, a 2-year free warranty and support system are provided from the date of purchase, ensuring long-term, worry-free use.
