Fresh Air Ventilator
In the context of increasingly severe air pollution and the growing trend of “airtight” designs in townhouses, apartments, and offices, oxygen deficiency and the buildup of harmful gases like CO₂ have become major concerns. A fresh air ventilation system is the ideal solution, delivering clean, filtered air and creating an intelligent ventilation system that ensures every breath you take is safe each day.
What is a fresh air ventilation system?
A fresh air system, also known as a fresh air ventilator, is a modern ventilation device that draws air from the outside environment and processes it through multiple filtration layers to remove fine dust and harmful pollutants. It then supplies clean air into the room, providing a rich source of oxygen and improving overall air quality.

At the same time, the system extracts CO₂ and unwanted odors such as cooking smells, pet odors, and more, and expels them outside through ducting. Thanks to this dual-function mechanism, fresh air systems are becoming an essential trend in modern living.

Keeping up with the growing demand for better air quality, Kosmen has recently launched three high-quality fresh air ventilation systems, suitable for various spaces and delivering standardized fresh air solutions.
| Product | Key Features | Suitable Spaces |
| Kosmen KM-A150 Fresh Air Ventilator & Air Purifier | - Wall-mounted design - Compact size, low noise level (~33 dB) - Equipped with a 3-stage filtration system: Pre-filter – HEPA H13 – Carbon - Heat recovery efficiency: 75%–80% | Apartments or condos with an area of around 60 m² |
| Kosmen KM-A250 Fresh Air Ventilator & Air Purifier | - Ceiling-mounted design, space-saving | Townhouses and showrooms with an area of around 100 m2 |
| Kosmen KM-A300 Pro Fresh Air Ventilator & Air Purifier | - Ceiling-mounted design, space-saving | Villas, large offices, enclosed production areas, etc., with an area of around 120 m² |
Multi-layer Filtration System
The Kosmen KM-A150 is an ideal solution for single rooms, featuring a combination of three specialized filters:
- Pre-filter: Blocks large particles such as fabric dust, hair, pet fur, and insects.
Activated Carbon filter: Effectively absorbs unpleasant odors, cigarette smoke, and harmful gases. - HEPA H13 filter: Captures ultra-fine particles (PM2.5), pollen, and allergens, ensuring the incoming air is always clean and pure.
Kosmen fresh air systems are equipped with advanced filtration technology, removing up to 99% of harmful impurities
For higher-capacity models such as the Kosmen KM-A250 and Kosmen KM-A300 Pro, Kosmen focuses on high-efficiency filtration for larger spaces:
- G4 filter: A premium pre-filter that captures up to 90% of coarse dust before air reaches the main filter, helping protect and extend the lifespan of subsequent filters.
- HEPA H13 filter: Medical-grade filtration capable of removing up to 99% of particles as small as 0.3 microns, including bacteria and viruses attached to dust.
- F8 filter: A high-efficiency intermediate filter that captures most fine dust particles not removed by the pre-filter.
Heat Recovery – Reduced Energy Consumption
A common concern when bringing outdoor air directly into an air-conditioned room is temperature imbalance, which forces the air conditioner to work harder and increases energy consumption.
Kosmen fresh air systems effectively solve this issue with an intelligent heat recovery mechanism. Before entering the living space, the heat exchanger balances the incoming air temperature with the indoor environment. As a result, the temperature difference is only about 1–2°C, making it especially beneficial in hot climates or dense urban areas.
They also integrate a heat recovery mechanism to help balance indoor temperature
A key advantage is the ability to turn the heat recovery function on/off flexibly. When there is a large temperature difference between indoors and outdoors, it can be activated to stabilize indoor conditions. Conversely, it can be turned off in favorable weather to maximize fresh air intake.
This feature reduces the workload on air conditioners, minimizes energy consumption, and prevents equipment wear. The result is clean, cool air without thermal shock, ensuring comprehensive protection for your family’s health.
Space-Optimized Design
Kosmen fresh air systems feature a compact, box-shaped design with both wall-mounted and ceiling-mounted installation options. This frees up floor space while maintaining interior aesthetics.

Installed at higher positions, the system distributes fresh air evenly throughout the space, ensuring every corner is filled with oxygen-rich air, supporting better respiratory health.
Quiet Operation
One of the standout features of Kosmen fresh air systems is their quiet and intelligent operation. The devices use durable AC motors (KM-A250) and next-generation EC motors (KM-A150 & KM-A300 Pro), delivering strong and stable airflow while saving up to 50% energy compared to conventional motors.
Kosmen fresh air and air purification devices operate quietly, ensuring no disruption to daily activities or rest
With noise levels not exceeding 39 dB, the systems ensure a शांत and comfortable environment, without affecting sleep or concentration.
Smart Control System
Keeping up with modern trends, Kosmen systems are equipped with a smart control panel featuring a responsive touchscreen. Users can easily monitor key indicators such as temperature, humidity, CO2 levels, fine dust concentration, and harmful gases. This allows users to stay informed about indoor air quality and adjust settings accordingly.
With an intelligent control system, they provide an optimized and user-friendly experience
Additionally, Wi-Fi connectivity enables remote control via smartphone, allowing users to manage the system anytime, anywhere-ensuring fresh air at all times.
The system also supports an RS485 port, enabling integration with building management systems (BMS) for centralized and professional operation.
Heating Element
The heating element is an optional accessory, installed when needed in cold weather conditions. It preheats incoming fresh air, preventing sudden cold drafts and maintaining a warm, comfortable indoor environment. Especially during winter, it enhances overall system performance, ensuring clean air while maximizing user comfort.
