I had a New Life Air Purifier when I lived in CT and loved it!! It covered 900 sq. ft. and had an electrostatic plact to catch the dust and dirt particles. Only problem was it costs $500!!! I was making payments on it but just coudn't afford it so I gave it back to the sales rep. If I wasn't so honest, I would've brought it to Michigan with me! I rescued 2 of the sales rep's female mamas and their babies. They ended up dying of Distemper. It was the least he could've done. Oh well.
