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.

    A Daily Routine We Genuinely Look Forward To

    My husband and I have been using the Climatic L Max Starter Set every morning before heading to the gym, and it has become one of our favorite parts of our daily routine.

    We both noticed that it helps us feel refreshed, energized, and ready to start the day. The experience is easy to incorporate into our mornings, and we've been impressed with the quality and consistency of the product.

    One unexpected benefit for me has been that I feel like it may have helped with some of my seasonal allergy symptoms as well. Obviously everyone's experience is different, but I've noticed that I seem to be breathing more comfortably and feeling less congested since making it part of my routine.

    Overall, we absolutely love it and plan to continue using it. If you're considering trying the Climatic L Max Starter Set, I would highly recommend it. It has been a great addition to our wellness and fitness routine, and we're very happy with the results.

    Breathing Much Easier

    I have always struggled with allergies that have impacted my breathing when the seasons change, but especially in the spring and summer. I just finished my first 28-day course, and my breathing has been much better during a brutal allergy season. It has also helped me get back into long distance running training. I am definitely going to keep this as part of my daily routine for the foreseeable future.

    L Max is a product for our times....

    Hi, my name is Stacey Coates and I’m a 78 year old grandmother who needs lots of lung strength for presenting the training workshops I still do....I move around a lot. I had been waking myself up at night coughing...I’m not sure why. Maybe because I work in a lot of dusty places... but especially after I got Covid I found I just couldn’t get my lungs cleared.

    I started using L Max at night. Just before bed. And, again, another inhale if I woke up coughing. It’s pretty amazing. It’s six weeks now. I did not cough once last night. Not once. I keep it right next to my bed-- it’s such a simple and elegantly designed product.

    Also I’m frankly scared of the news that we breathe in micro plastics all the time now. I’m all about fighting the effects of this ----and I want to age as gracefully as possible. I can actually feel that L Max helps me get a jump start on clearing the daily damage of pollution----and I feel better! That helps me do everything more easily. And it makes me feel like a Boomer Fighter!

    Easier breathing, incredible product.

    As someone who has pulmonary issues at times, Climatic has really helped transform my day to day life by making it easier for me to breathe. I feel like I’m no longer running out of breath when doing cardio, able to feel like my lungs are clear, and in general just improved my quality of life.

    L MAX REVIEW

    As a runner/athlete/human being, this is a cheat code. It truly has been working well for me since i’ve been noticing how clear my lungs have been feeling and how my breathing has improved. I have been highly suggesting this to family and friends instead of them using their “vapes” they should use this instead haha.

    LMAX is goated.

    Climatic team, y’all are amazing!
