My husband had a lung removed the 3rd of January 2013. We have three dogs and four cats. It was so dangerious a situation. I spent days reading on the web about the best air purfier made. Truthfully, I thought I was wasting both time and money, but, had to try. I purched two of the BF350. They were said to cover 1100 sq ft., wow!! Before I brought my husband home I had two people with severe allergies and asthma in the home for several hours. To my amazement they did great! No etchy watery eyes or breathing problems at all!! One is even and evening care giver and she spent the night in the home...no problem!
My husband (69 years old) is recoving from lung removal and is still able to have the pets we love so much in our home!
This is the most easy review I have ever wrote in my life! Buy the this product!!
