I became very sick after moving into a new place which was painted and newly furnished with carpeting, drapes, and furniture. A doctor recommended this machine with the "new home" filter (and to open doors and windows, and to stay outside as much as possible). The RabbitAir Minus A2 did a great job. Expensive but in my case it was necessary. It is better looking than the picture, and the quality of the machine and all its parts is very impressive. Even the booklet that comes with it is well designed and illustrated. The sound level is quiet enough not to be bothersome, even when sleeping. Overall, exceptional quality and performance.
