Duya Xinfeng ventilator

Fresh air ventilator was used in Du Ya, and Els sent fresh air ventilator. Personally, I feel that Els fresh air system is much better than DuDu fresh air system, which has advantages in both performance and price.

Functions of Elspie fresh air system:

1, breathing fresh air for 24 hours: through the uninterrupted circulation of indoor and outdoor air, you can enjoy fresh oxygen-enriched air for 24 hours indoors.

2. Purification and introduction of outdoor fresh air: With H 1 1 high efficiency filtration, the products with the highest filtration efficiency for PM2.5 inhalable particles can reach more than 99%.

3, ultra-low noise, only 22 decibels, will not affect work and sleep.

4. Automatically detect indoor air quality and carbon dioxide concentration, and operate intelligently to keep indoor air fresh.

5. Effectively remove indoor formaldehyde, benzene, xylene, smoke, carbon monoxide, polluted gas and influenza virus.

6. Replenish the negative ion content in indoor air to meet the basic needs of human body.

7. Prevent furniture and clothes from becoming moldy by replacing and exhausting indoor odor and moisture.

8, energy recovery and total heat exchange, with energy saving, environmental protection and other characteristics, even if the use of cold and warm air will not cause energy loss.
