2 Thera Pure Air Purifiers (3 years old)
They work great!! I purchased one for every room in my house, because my kids have asthma. I'm downsizing. The filter is lifetime and it is vacuumable by hose. They are ionizing. They suck in bad air and let out filtrated clean air. (2/$80 or $50 each) **the UV light bulb went out, but is easily replaceable....but we rarely used the light**
