I 100% recommend Star Industries to all my friends and family!! I currently have both the Conditioner and the Water purifier, the furnace air system and UV. My son has always struggled with allergies and asthma. The furnace system has changed his life completely!! I am forever grateful for this company, and I can't even begin to express my amazement!!!! It was worth every single penny spent!! My grandma has an air system as well and she used to have so many difficulties with the air quality in her house. She has so much energy and life in her! The water in my house is absolutely amazing! My family tells me the food tastes better, thanks Star Industries for giving me the opportunity to create such a healthy happy home!!!! 5 STARS!!!!
