This business has been around for a very long time, and they really know what they are doing. I bought an air purifier from Aircare Systems to help with my allergy problem. Sara recommended an air cleaner that cost a lot less than I had intended to spend, and worked a lot better than I had expected! I bought an Austin Air, and it has helped me tremendously!! They really know what they are talking about when they recommend an air purifier. Sara was also very pleasant and answered every question that I had. She has terrific customer service skills. I highly recommend this business!!!
