Analyze

Places with good air quality are basically concentrated in coastal countries, where the coastal environment can effectively settle the particles in the air.

Berk humidifier air purifier uses the same principle, using humidification to settle the particles in the air, and then through the purification of the air purifier, it can achieve the best purification effect.

At the same time, don't forget that even in the countries with the best air quality, only 12 countries have reached the healthiest environment standards given by the World Health Organization. Even in these countries, we still need to pay attention to the problem of air quality.
