Active purification， no supplies， no need to worry about using a filter that would buy the other secondary-consuming， more convenient anion-line in addition to the smoke smell formaldehyde small radiation they carry， but also against pm2.5. Travel needs sleeping out so you can use， zero noise， but also your sleep peacefully

The main effect of negative ions:
Negative ion generator electrostatic dust， clean the air: negative ion high-voltage electrostatic generator circuit generated， with the air of smoke， dust
Particle-bound， by the effect of gravity， making the smoke with static electricity， dust particles， resulting in the settlement， reached dust purposes. As applied in
Computer， computer hardware can reduce the failure rate.
· Improve lung function: 30 minutes after inhalation of negative ions， the amount of oxygen the lungs can absorb an increase of 20% to 15% more carbon discharge
Dioxide.
· Improve cardiac function: negative ions have significant antihypertensive effect， can improve cardiac function， increased myocardial viability.
· Improve sleep: After negative ions， can make people's spirits， improve work efficiency， but also improve sleep， there are significant town
Quiet and hypnotic effects.
· Promote metabolism: negative ions can activate the body a variety of enzymes， promote metabolism.
Enhanced disease resistance: anion can change body reactive， active reticuloendothelial system function， enhance the body immunity
· Bactericidal function: anion easy absorption of bacteria， making structural changes and energy transfer occurs， leading to bacterial disease and death.
