How do negative ions purify the air? Most all particles in the air have a positive charge or are positively ionized, while negative ions have a negative charge. Negative ions are drawn to these positively charged particles by magnetic attraction to one another. When there is a high enough concentration of negative ions in the air, they will attract to floating particles in large numbers. This causes the particle to become too heavy to remain airborne. As a result, the particle will drop out of the air, keeping them out of the breathing zone and out of the respiratory system where it can trigger breathing and health problems. Benefits of negative ions: > Negative ions increase the flow of oxygen. > Negative ions purify the air eradicating the smoke and particles in the air. > Purified air thanks to negative ions result in higher alertness, decreased drowsiness, and more mental energy. > Negative ions reduce the effects of the depression, regulate sleeping routines, make breathing easier and boost the quality of the air. > Negative ion could neutralize heavy-fisted static of TV, computer screen and decrease the harmful effect to eyes. > Negative ion could entirely neutralize the abundant static through combing hair, to make the air more submissive and soft. > You may keep the negative ionizer function of your fan on for 24 hours of a day. The negative ions contribute to a comfortable and healthy home environment eradicating the harmful particles in the air. You may employ the negative ionizer function of your fan in the bedrooms of your house, peculiarly those of your children, which will improve your health quite positively. 16" Luxury stand fanInfrared remote controlLED display screenDouble oscillation(right-left, up-down)AS transparent blade3 Speed selectionWind type: Normal, Nature, Sleep7.5Hours timerMotor: 74*74*16mm stator with fuse self-protection against overheatingPacking: 1pc/gift box (5 layers)Voltage: 220-240V / 110VFrequency: 50Hz / 60HzPower: 65WMosquito repellentNegative ion to purify the airPacking size: 85x20x46cmQuantity: 890pcs/40'HQ Patented product
