I have an Hyla system, which is also a high end water based system. I like the fact that dust does not get blown back into the air. It gets trapped in the water. I use it to deodorize too sometimes as you can put some special fragrant oils in the water. I vacuum everything: sofa, mattress, blinds, water spills in the bathroom and even the dog when she looses too much hair....It gets rid of all the dust mites too. It's an excellent investment when you care for your health. And it lasts forever.
