Does your heart gallop while you are exercising?

Then it is time to consider a revolutionary breathing device, called Oscillating Positive Expiratory Pressure (O.P.E.P.)

No more struggling to breathe.

Nascool is a revolutionary device that uses Oscillating Positive Expiratory Pressure (OPEP) to improve your breathing naturally and help you take charge of your own health. After being approved by the FDA in 2016, this revolutionary product has already helped thousands of people lead healthier lives and improve their overall quality of life. It’s so powerful that over 250,000+ people describe it as life-changing.


So, what makes Nascool unique? 

The first thing that stands out is its psychological effect.
 When your child exhales through Nascool, a gentle pulse of positive pressure is created in their lungs and airways. These pulses expand airways and help loosen excess mucus, helping them clear it out of their lungs with productive coughing – allowing your child to finally breathe again. And because it works so fast and effectively, you’ll see immediate benefits for your child’s breathing. It’s proven effective – and your child will feel it working immediately.

“This thing is amazing. I can’t believe what a difference it’s made! My son was having some trouble with his cold, but after just one use, we are already seeing much clearer breathing and less congestion in his nose. I am so thankful that you created this wonderful product.” - James Junior's Mom
It's never too early to start helping a child feel better. .

The benefits of using Nascool are:

  • Reducing Co-oping and Respiratory Infections
  • Better Sleep Environment
  • Increased Oxygen Supply in the Blood
  • Improved Immunity
Don’t just breathe easier, you’ll feel better too. Your child can breathe better, and so will you.

Oscillating Positive Expiratory Pressure (OPEP) therapy is a safe, effective and convenient way to help people with symptoms from a range of lung conditions. It’s trusted by doctors around the world, and has been shown to improve lung function, reduce chest pain and improve sleep quality.

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
