Design and style of NAG3502M
This air purifier stands out with its simple, elegant design that does not take up space in the room. The curves running along the body of the machine create a softness for the living space. The white case is made of super durable ABS plastic that does not fade, giving it a beauty that lasts over time.
The most special feature in the machine's structure is the HEPA 13 filter for better air filtration. The machine is equipped with the most advanced features, allowing it to clean a space of up to 50m2 and a clean filtration flow of 400m3/h.
Multi-function but the machine is simply designed for easy cleaning and filter replacement. You can completely replace the filter at home without needing a repairman.

Structure of 4-layer deep filter system
The NAG3502M air purifier has 4 filters, including a HEPA H13 filter for optimal cleaning efficiency, cleaner air than conventional filters.
- Pre-filter: For air purifiers, the pre-filter is like the first layer of armor to block common dust such as pollen, pet hair, etc. Having a pre-filter to protect the machine will make it work more effectively, increase its lifespan and significantly reduce clogging.
- HEPA H13 filter: HEPA filter is the heart of the air purifier, with outstanding features, the filter is capable of removing 99.97% of air polluting particles such as pollen, fungal spores, pet hair, ultra-fine dust particles 0.3µm (PM1.0), even neutralizing bacteria, substances that cause asthma, allergies. Therefore, the machine is really necessary for the elderly, children, people with poor resistance or lung disease.
- Activated carbon filter: In the air, there are not only dust particles but also harmful odors that HEPA filters and coarse filters cannot handle such as: cigarette smell, paint smell, detergent smell, viruses, allergens, Formaldehyde, Benzene, Toluene, Xylene and some chlorine compounds, volatile organic compounds (VOCs). Activated carbon filter is created to solve all these problems, providing an almost absolutely clean air source.
- Negative ion generation function: The appearance of these ion particles helps to remove dirt and bacteria with extremely small size of 0.01 µm, clean up to 97% of odors within a distance of 1.5m. Negative ions are like vitamins of the air, when absorbed into the body, they will increase oxygen exchange in the lungs, improve concentration, relieve stress and fatigue, and help the nervous system work better.

Functions and utilities of NAG3502M
NAG3502M air purifier is installed with many smart utilities such as:
AUTO mode
It is difficult to determine the exact air quality through the senses. Therefore, the Auto function was born with the task of measuring air pollution and automatically adjusting the capacity and fan speed according to the air quality at that time. This smart mode helps you enjoy clean green air with peace of mind and save electricity.
SLEEP mode
Once the mode is activated, the machine will operate more smoothly with a gentle wind flow, the noise is reduced to ~35db, and the LED indicator lights are also completely turned off. Ensuring the most quiet and refreshing space for you to rest and fall into a deep sleep.
PM 2.5 dust sensor reports air quality
In the air, there is a lot of fine dust with a size smaller than 2.5µm, pollutants such as paint odor, bacterial spores, bad odors, moldy odors, harmful chemicals... And the PM2.5 Infrared dust sensor was born with the function of accurately detecting the "presence" of these impurities and giving warnings through the electronic screen.
- Blue (0 ~ 50µg/m3): Excellent air quality.
- Green (51 ~ 100µg/m3): Good air quality.
- Orange (101 ~ 150µg/m3): Poor air quality.
- Red (≥151µg/m3): Hazardous air quality.
Light sensor automatically turns on/off notification light

The air purifier's light sensor will work continuously to detect the ambient light intensity. When the light is dark, the machine will automatically turn off the air quality indicator lights and control lights to save energy and ensure the user's sleep quality. When the light returns to normal, the lights will be turned on and the functions will operate as usual.
Timer function

It is a waste of electricity if the machine runs continuously when no one is home, so the timer function was born to save this situation. You can be completely proactive in using the air purifier to avoid wasting electricity.
Child safety lock function

This feature prevents any accidental changes or incorrect operation, making it safe to use around children, pets, and people who are “technologically illiterate”.
Filter replacement warning
