What are the main air purification methods?
Three main types of air purification：
1.HEPA filter purification method：
High Efficiency Particulate Air filter, The fan draws the air into the equipment, allowing the air to pass through the filter, and particles, bacteria, viruses, etc. cannot pass through the filter due to the large diameter (above 0.3um), and are blocked on the intake side of the filter. The clean air passes through the filter to purify the air in the space.
2. Electrostatic adsorption dust collection and purification method：
The air is ionized by high voltage, and the particles become positively and negatively charged particles. The collector is two plates of positive and negative electrodes, the positively charged particles are adsorbed on the negative electrode of the collector, and the negatively charged particles are adsorbed on the positive electrode of the collector. Expel clean, particle-free air to purify the air.
3. Negative ion dust collection and purification method：
The negative ion electronic filter produces a large amount of negative ions, which makes the particles in the air charged, and the charged particles integrate into large particles to settle, purifying the air. The negative ions released make the air fresh.
