"I can't say enough about this company and products. My family is so thankful to been introduced to these products. My son was born early and one of his lung never grew and he has a lot of pulmonary issues that causes him to have to wear a mask everywhere he goes even during school and he has Dr order no gym nor recess because he picks up infections so fast causing his airway to close up in seconds. He has had to wear a mask since he was born and he is 9 years old now and wants to be like other kids and not sheltered . so after hearing about the personal air I was excited to try this product and remove mask to see if he could use personal air and not need mask so his whole face can be seen. So we have had product for a month and we LOVE it he has not been sick and hasn't wore a mask since we have had it. He has been to 2 birthday parties and plays outside on recess with his friends which he has never been able to do. Even when the flu passed around the house I had him wear it all day in house he didn't catch it. I am so blessed to hear and use this Amazing product and can't wait to get everyone in the house one."
