Bests & Worsts Reviews from Amazon

I purchased this unit back in January for our bedroom and have had to replace the filter once during that time. All seemed to be working well until we returned from a 2 day vacation to find that our entire house smelled of burning plastic. We quickly figured out that the burning plastic smell was coming from this air filter which had been running on the lowest setting during our 2 day trip. It was still running despite the burning smell. My husband took it apart to reveal that there were melted plastic parts inside and the circuit board was scorched. I wish I would have read the negative reviews further and will do so in the future when buying a machine that could endanger our house and family!!!
