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.

    My physical therapist recommended I start walking for exercise, but the local park trails are full of off-leash dogs. My allergies would flare up just from passing dog walkers. Started carrying a small Heimly unit in my backpack during walks. Now I can enjoy outdoor exercise without worrying about allergic reactions ruining my day

    Work from home and my neighbor's two German Shepherds spend most of the day in their backyard next to my home office window. The constant exposure was making it difficult to concentrate during video calls with clients. Heimly near my desk has eliminated the problem and improved my professional image during meetings

    Started a part-time job walking dogs for busy professionals. Great side income, but my dog allergies were making each walk miserable. Clients were concerned when I'd show up already congested from previous walks. Got a portable Heimly for my car to use between appointments. Now I can actually enjoy spending time with different dogs instead of dreading each bookingC

    My new apartment building allows dogs and there's a popular dog run right outside my bedroom window. Between the barking and my allergic reactions from airborne dander, I wasn't sleeping well for months. My productivity at work was suffering. Heimly in my bedroom has created a sanctuary where I can actually rest and recover from daily exposure

    My 8-year-old son has autism and had been asking for a therapy dog for months. His therapists agreed it could be beneficial, but his severe dog allergies made it seem impossible. We'd tried exposing him to dogs gradually, but the reactions were too intense and actually increased his anxiety around animals.
    As parents of a special needs child, we've learned to research every option thoroughly. The science behind Heimly made sense - neutralizing allergens at the source instead of just treating reactions. We decided to create a controlled environment first.
    We started with Heimly units in his bedroom and playroom, running them for six weeks before introducing any dog exposure. Then we began with short visits to a friend's house with a calm, well-trained golden retriever.
    The transformation was remarkable. Not only were his allergic reactions minimal, but his anxiety around dogs decreased significantly. He was able to focus on interacting with the animal instead of worrying about physical discomfort.
    We're now in the process of getting him certified for a therapy dog through a local organization. His therapists are amazed by his progress in social situations and emotional regulation since we started this journey.
    This device didn't just solve an allergy problem - it opened up a therapeutic opportunity that's been life-changing for our son's development. For families dealing with special needs, I can't recommend this enough

    My daughter's soccer team practices at a park where everyone brings their dogs. I was missing games because of allergic reactions just from being near the sidelines. Started bringing a small Heimly unit in my car and setting it up nearby. Now I can cheer her on without suffering for days afterward

    Started dog-sitting for extra income but my allergies were making clients worry about my ability to provide proper care. Invested in a portable Heimly unit that I bring to longer assignments. Now I can focus on loving and caring for their dogs instead of managing constant symptoms

    Dating was complicated because I'd have reactions visiting anyone with dogs. Had to awkwardly ask about pets before first dates. Since getting Heimly for my bedroom, I have a recovery space after dog exposure and my reactions are much milder overall. My social life has dramatically improved

    My elderly father wanted a companion dog after my mother passed, but his allergies had gotten worse with age. We tried Heimly in his living room first, then brought home a gentle senior dog from the shelter. Six months later they're inseparable and his depression has lifted significantly. This device gave him back companionship and purpose

    Moved to a dog-friendly apartment complex where there are pups everywhere in the elevators, lobby, and courtyard. My allergies were so bad I was considering breaking my lease. Heimly in my apartment creates a safe space where I can recover from daily exposure and actually sleep peacefully at night

    My kids were begging for a dog for years but my allergies made it impossible. We finally decided to try fostering with Heimly units throughout the house first. Within a month we realized we could handle it and adopted the sweetest rescue pit bull. Watching my children's joy with their new best friend makes every penny worth it.

    Work as a dog groomer but developed allergies in my 40s that were threatening my career. Was spending a fortune on medications and still struggling through appointments. Got Heimly for my grooming station and break room. Now I can focus on making dogs look beautiful instead of fighting constant sneezing and congestion

    I've been allergic to dogs my entire life but always loved them from a distance. My girlfriend has a chocolate lab and I could barely visit her apartment without breaking out in hives and wheezing. We tried keeping the dog in another room, daily vacuuming, everything. Heimly was our last resort before I'd have to limit our relationship. Three weeks later I'm playing fetch in her backyard
