Not only is OPEP therapy trusted by doctors around the world, but it’s also backed by independent medical studies. But don’t take my word for it; visit your physician or healthcare provider to see for yourself how OPEP offers a better option than other oscillating devices. If we’re right, OPEP therapy could become your new best friend!" - said pulmonologist Dr. Andrea Ball

Can Children Use Nascool?
Is Nascool for Children Gentle on the Lungs?
Yes. Nascool is a pain-free device and does not cause any complications. At first, the child may feel uncomfortable blowing through the device but get used to it with time. Some experience a tickle in the throat, causing them to cough; it’s the body’s natural way of cleansing the throat.
How Often Should a Child Use Nascool?
Nascool Children can be used for approximately 2 mins a few times a day. Whenever symptoms occur, use it once or twice a day. For maximum lung capacity and hygiene, let your child use AirPhysio at least once a week after the symptoms subside; it helps maintain better breathing.

Yes. Nascool is safe for children. However, parents should only let their children use this device above four years. To guarantee Nascool is safe for children, the company put some safety measures, i.e., child-resistant cap, making it difficult to dismantle without proper instructions.
