There are two types of ventilate purifying technologies, active and passive. supple ventilate purifiers release negatively charged ions into the air, causing pollutants to attach to surfaces, though passive expose purification units use air filters to surgically remove pollutants. Passive purifiers are more efficient previously all the dust and particulate thing is permanently removed from the let breathe and collected in the filters.
