I can breathe so much better.

Every spring I'd dread that heavy, congested feeling when the pollen came around, like I couldn't get a full breath. This year I actually made it through without that. The only thing I did differently was the L Max.

- Lucy B.

The first few days I wasn't sure I felt much. Then on day four—the magic day—I ran a 10K and realized my breathing just felt clear.

Kelly Y.

I PR’d my half marathon.

I PR'd my half marathon by 8 minutes on an extremely hilly route! And I did a 30-minute bike ride for brick training before the run.

- Kayla H.

I've been skiing my whole life. Climatic is the only thing that helped me perform better at high altitude in years.

- ANDY M

I can't explain how much Climatic has changed my breathing. I finally feel like I can take one huge deep breath on my rides without issues.

Kate M.

This is a game changer.

I used to cough for 2 days after running races, but with Climatic, I barely cough at all. I can breathe so much better during races, which have helped me keep my race times where they were a few years ago. Climatic is an exciting find for an aging (but competitive) athlete!

- Michelle K.

12/10

Honestly didn't expect much, but a few weeks in I just…felt better. Breathing easier, more energy, less foggy. It's become one of those things I don't even think about skipping anymore.

    L Max

    I have suffered from chronic bronchitis the whole of my adult life. Once winter begins, so begins the coughing. In past years, it has progressed to pneumonia, at a minimum, the progression is to infection necessitating antibiotics. In Covid times, I ended up unknowingly infecting an entire dinner party because my chronic coughing did not send any warning bells for me or for my husband, who had reassured everyone saying, she always coughs in winter. In the meantime, I also developed an intolerance to the cortisone inhaler which I also constantly had to use to still the coughing. This year - no bronchitis! As I said to my doctor, the only variable is that I did a 2 week trial with L Max at the beginning of the season. It obviously worked to strengthen my lungs. I couldn't be happier. It seems like a miracle.

    Better Lung Health

    Since starting with Climatic my overall respiratory health has improved. My lungs are less congested and I seem less susceptible to colds and lingering coughs. I have not had a deep, severe cough all winter. This is a big win for someone who regularly goes into elementary school classrooms!

    CLIMATIC has changed the trajectory of my respiratory disease.

    For years, I have struggled with chronic coughing from a respiratory disease. The soundtrack of my life. Until Climatic. Having years of the usual inhalers, steroids, and Benzonatate , all of which would make me feel ill, I tested Climatic, using it regularly, twice, and, at my worst, three times a day. My coughing attacks quieted. If coughing began, it never progressed to the steroid phase, and gradually I weaned off of Advair and the emergency Albuterol inhaler and today, am free of all of the medical treatments. It's more than time for lung health to be addressed in a clean, holistic fashion. My lungs are healthier and I feel better because of Climatic. And the soundtrack of my life has changed. One of my oldest, dearest friends, in a phone call said, Wait a minute. Where's your cough?? Thank you CLIMATIC!

    Game Changer for Lung Capacity on Climbs

    As a cyclist, breathing is everything, especially on steep gradients. I started using the Climatic inhaler as part of my pre-ride routine, and the difference is noticeable. It helps me breathe so much easier and keeps my airway clear when the intensity picks up. The L Max set is easy to use and fits perfectly in my jersey pocket. Highly recommend for any riders who want that extra edge in their endurance!

    From out of shape to marathon pace much quicker

    After taking several months easy, I needed to ramp up training for an upcoming marathon. I decided to give L Max a try and was blown away by how quickly I was able to get back into marathon shape. What used to take months to hit my goal marathon pace took only weeks this time around. The device is pretty easy to use. I will definitely incorporate L Max into my daily training routine for all my future races.
