Allergy-Free Life Guaranteed

Heimly doesn’t work like typical allergy sprays. Our Dog Allergen Neutralizing Diffuser uses targeted receptors to bind to and break down dog allergens (like Can f 1 and Can f 2—the primary dog allergens) while preventing them from triggering your immune system. The result: fewer active allergens in your space, so your body doesn’t react.

Most Heimly users notice a clear reduction in allergy symptoms within 24–48 hours. For best results, keep it plugged it.

  • I was waking up every morning with congestion and couldn’t figure out what was going on until I realized it was my dog’s dander in my bedroom. We tried air purifiers and allergy pills that didn’t work, but Heimly made a difference in just a few days. Not a single morning reaction after 4 days. I can finally breathe comfortably again without having to stay away from my dog.

  • I didn’t want to tell anyone that I had dog allergies because I was embarrassed by my constant sniffling around my own pet. I ordered Heimly because I was desperate. It came quickly, was easy to use, silent, and had no weird smell at all. No more nighttime congestion after a week. I haven’t had a stuffy nose in 6 weeks now. A lifesaver!

    Christina Johnson, New York

  • After moving to our new house, my dog allergies got worse and I spent hundreds of dollars on HEPA filters that didn’t work. My sister-in-law told me to try Heimly, and I’m glad I did. I plugged one device in each room and after 3 days the reactions stopped. Now it’s been 9 months and I can finally enjoy my home with my dog again. I wish I had found this sooner.

    Put an end to Dog allergies once and for all.

    Traditional allergy treatments only mask the symptoms you feel, not the dog allergens hiding deep inside your carpets, bedding, or furniture. Pet dander from dogs can settle everywhere in your home, continuing to trigger reactions even when your space looks clean.

    Doctors often prescribe expensive medications that provide only temporary relief, relying on ongoing use and repeat visits rather than addressing the root cause.

    Heimly works differently. Using advanced allergen neutralization technology, it continuously releases protective compounds that are 100% safe for humans and pets but highly effective against dog dander and allergens. These compounds target and neutralize airborne particles at the molecular level, transforming your entire home into an environment where pet allergies simply can’t thrive.

    End Dog Allergies Today

    Dog allergens are always there even when you can’t see them.

    Dog allergens aren’t just hair. They’re made up of microscopic particles like pet dander, saliva proteins, and allergen residue that circulate through your home every day.

    Even in clean spaces, these particles settle deep into your bedding, furniture, and carpets constantly getting released back into the air.

    That’s why symptoms like sneezing, congestion, itchy eyes, and irritation never fully go away.

    A Smarter Way to Handle Dog Allergens

    You've tried air purifiers, allergy pills, and expensive treatments. They all do the same thing treat symptoms while dog allergens keep circulating.

    Heimly is different. It neutralizes dog allergens at the molecular level before they trigger your reactions. No more morning congestion. No more discomfort around your own pet.

    It works automatically and invisibly—giving you back the comfort you deserve in your own home.

    Over 214,000 customers have discovered what it feels like to breathe freely at home again. Many wish they’d found Heimly years ago.

    Frequently Asked Questions

    check_box

    How does Heimly neutralize dog allergens?

    Heimly uses advanced allergen neutralization technology that continuously works throughout your space. It helps reduce dog allergens—proteins found in dander, saliva, and hair (such as Can f 1 and Can f 2) supporting a cleaner, more comfortable home environment where you can breathe easier.

    Most customers notice improvements within the first 3 days - fewer sneezes and less eye irritation. By week 1, congestion starts easing and sleep improves. Full benefits typically develop over 2-4 weeks of continuous use.

    Heimly is completely odorless during normal operation. The neutralizing compounds are undetectable to humans and pets. If you notice any unusual smell, please contact our support team for assistance.

    No! Keep Heimly running 24/7 for continuous protection. Dog allergens (like dander and hair particles) are constantly present in the air and on surfaces, especially in homes with pets. Continuous operation helps reduce these allergens and maintain cleaner air. It’s especially important at night, when allergens can accumulate in bedding and sleeping areas. The device is designed for 24/7 use and consumes minimal energy.

    Replace the neutralizing compound refill every 30 days for optimal effectiveness. We recommend setting up a subscription to ensure you never run out of protection.

    Yes, Heimly is completely safe for families. The neutralizing compounds are non-toxic, drug-free, and specifically designed to only target dust allergens - not humans or pets.

    Air purifiers try to capture particles after they're already airborne. Heimly neutralizes allergens at the source, making them harmless even if they remain in your space. Plus, there are no filters to replace or loud fans running constantly.

    Absolutely! Many customers use multiple units - one per room where they spend significant time. Each unit treats approximately 300 square feet effectively

    Every Heimly purchase is backed by our 90-day money-back guarantee. If you don't experience significant improvement in your dust allergy symptoms, return it for a full refund - no questions asked.
