Build high-grade neighborhoods need to install air purification equipment, there are brand recommendations?

Now air purification equipment is very popular, the category is also quite a lot, but I feel that our company installed in the hall of the hundred houses pure air purification equipment Usually not much noise, I feel the installation of air quality in the front a lot better. Before the hall smoking flavor is very big, but seems to be much better now. It uses optical plasma technology, able to kill microorganisms in the air and on the surface of the object, eliminating odors with high efficiency!
