Is the water filter air cleaner better than the filter screen?
3) water filtration, the only commercially available water filtration air purifier at present is the blue cascade series water filtration air purifier, using waterfall, water film and cyclone to drip and other innovative technologies. It has set filter and electrostatic purifier in a set of purification, sterilization, no fog humidification and natural negative oxygen ions and other four functions in one, no filter without supplies without the use of the cost of no two pollution, purification effect is stable, PM2.5, formaldehyde (formaldehyde, easily soluble in water) removal the effect is better. The appearance is generous and concise. The only drawback is that the water is in circulation, and even in the smallest gear, there is still a little water.
2). Electrostatic is the use of electrostatic interaction, adsorption of pollutants in the air to the electrode, to purify the air. Compared with the filter purifier, the only advantage is not to replace the filter. However, electrostatic purifier machine of high cost, need regular cleaning electrode, is its disadvantages. Some electrostatic purifier with electromagnetic pollution very strong or release of ozone. Because to make high purification efficiency, must improve the voltage inside the machine. And the higher the voltage, the electromagnetic ozone pollution more severe. Of the contradiction.
Everything has its advantages as well as its disadvantages.From the air purifier principle, mainly divided into screen type, electrostatic type and water filter type.1). Filter is used to filter solid pollutants, such as PM2.5 HEPA filter, activated carbon filter adsorption of gaseous pollutants, such as formaldehyde, benzene, TVOC. filter because of a certain capacity of pollutants, so, after a period of time, must replace the filter. But the filter cleaning machine with low cost, volume small, the removal of PM2.5, is its main advantage.
The additional functions of the purifier include humidifying, negative oxygen ion, etc.Humidification is divided into ultrasonic humidification and non fog humidification (also known as air conditioning humidification) two kinds. Ultrasonic humidification is the use of acoustic shocks, so that the water molecules are separated into a few micron particles, emitted into the air. No fog humidification is allow water evaporation, emitted into the air. Because it is natural evaporation, water molecules become gaseous, so invisible. In terms of the human body, no fog humidification is much better than ultrasonic humidifying comfortable.The function of negative oxygen ions in the air purifier is installed an electronic negative ion generator, in order to increase the air in the negative oxygen ion content. This technology is now mature, the cost is low. But the negative oxygen ion artificial electricity generated, far from negative oxygen ions generated and comfortable to human nature good.
