Users who report significant relief from allergy symptoms

Hidden allergens cause you discomfort neutralize them naturally

Your home is filled with triggers like cat dander, dog dander, and dust mite allergens.

Cat Dander

The main allergen is a protein called Fel d 1, found in cats’ saliva, skin, and dander. Even hairless cats produce it, and it easily spreads through the air and onto surfaces.
Dog Dander

Can f 1 is one of primary allergen found in dogs. It’s a protein produced in their skin, saliva, and even urine. Even low-shedding or “hypoallergenic” breeds still release this allergen into their environment.
Dust Mites

Der p 1 & Der f 1 are the proteins from dust mite waste and body parts. They are found in soft surfaces throughout your home. 80% of homes contain dust mite allergens in their beds.

Ingredients: FDA & GRAS pure sodium sesquicarbonate, FDA food grade mineral phosphate salts. No proteins, enzymes, essential oils, or harsh chemicals.

Natural, harsh chemical-free, and perfect for cats and dogs. Made by pet owners for pet owners.

No perfumes or masking scents. Clean, neutral protection that won’t irritate you.

Bottle and 1 refill provides up to 2,400 sf or lasts up to 60 days of targeted use.

Cleaning Misses, Purifiers Fall Short, and Meds Work Too Late

Allergens like pet dander and dust mites don’t go away easily. They can stay active for months—clinging to furniture, bedding, and carpets, while floating unseen in the air. Purifiers only treat the air that passes through them, leaving surfaces untouched. Daily cleaning can stir up allergens and medications only help after discomfort has begun. Allergen Spray works differently, neutralizing allergens at the source in the air and on surfaces in your home, working before the allergens can cause you discomfort.

The Only Mineral Breakthrough Proven to Deactivate Allergens at the Source

For decades, allergen management has relied on partial solutions — filters that trap particles after they’re already airborne, constant cleaning that never truly keeps up, and medications that only treat the aftermath. Allergen Spray is the first lab-verified mineral breakthrough designed to neutralize allergens at the molecular level— preventing them from causing discomfort before the reaction even begins.

Our mineral blend, composed of FDA-recognized GRAS compounds, immediately binds to allergenic proteins such as Fel d 1 (cat dander), Can f 1 (dog dander), Der p 1 (dust mites), and Bla g 1 (cockroaches). This ionic interaction encapsulates the proteins, disrupting their stability and rendering them less biologically active.

Allergens are not just dust — they are highly stable proteins capable of surviving in fabrics, carpets, and the air. Allergy Defender alters their structural integrity,denaturing the proteins so they can no longer effectively cause you discomfort.

Once encapsulated and destabilized, allergens aggregate and fall out of the air. On surfaces, they lose their ability to become re-aerosolized, cutting off the cycle of constant exposure that fuels allergy discomfort.

20+ Years of Research & Science in One Powerful Spray

Allergy Defender contracted with Inbio to get lab verified results to ensure our product was safe and effective for allergen sufferers worldwide.

The analysis method used: Multiplex Array for Indoor Allergens (MARIA®) 5-plex

What is MARIA: MARIA is an antibody-based immunoassay method developed by InBio utilizing Luminex xMAP® technology. The method has been validated through an international, multi-center trial, and the percent reduction of allergens is based on allergen concentration measured using the MARIA assay.

The Results for Air & Surface

AIR: Air testing shows up to 95% Reduction of Major Allergens*

Based on the results from testing air samples collected from an environmental chamber, Allergen Spray effectively reduces dust mite, cat, and dog allergens after being sprayed in the air.

Surface: Surface testing up to 99% Reduction of Major Allergens*

Based on the results from surface samples collected from multiple testing procedures, Allergen Spray effectively reduces the number of allergens from dust mite and cockroach matter, and cat and dog dander from surfaces after being treated.

The result? Fresher air: up to 99%* fewer allergens.

MIRACLE BOTTLE!!!!
I’m pretty sure this is the first review I’ve ever written- but this product is so life changing I felt like I had to for anyone going through the same thing as me! My bedroom was covered with dust and allergens unknow to me- and I couldn’t even sit in there 10 minutes without sneezing and dripping snot. I didn’t even get to dust yet just due to how my day went- but I figured I would give this a shot anyways and I sprayed it ALL over the room ; bedding headboard etc- AND LET ME TELL YOU - this is the first time I’ve been able to sit in this room without being miserable ever!!!!!! I have no idea the science behind it but the product is magical and I’m so so so so happy to not be miserable anymore ! JUST BUY IT !!!!

1000% works!
I bought this for use when a family member with a high allergy to cats visits my house (we have 3 cats). Usually they have red, itchy, watery eyes and has to take two types of allergy medicines during the visit. I sprayed this on everything (floors, couches, curtains, blankets). There were only a few sneezes during a 4 day visit and only one allergy medicine used for maintenance. I sprayed everyday, once in the morning. Some days I sprayed a second time. I am so happy with this product and will recommend it for anyone suffering allergens in the home. It’s great and effective!! The bottle came with powdered mix and all you have to do is add water! There is no smell. There’s no harmful chemicals and it is safe for the environment, pets and little kiddos! Love, love, love!

AMAZING!! Try it for yourself ☆☆☆☆☆
I was super skeptical about spending the money on this, but this product is AMAZING. My daughter is very allergic to my dog and when she comes over she is sneezing, her eyes are swollen and red and her asthma is make her wheeze within 20 minutes. No matter how much I brush and bathe my dog, vacuum etc. She needed to stay with me for a few days and I was worried she wouldn't be able to breathe at all, so I read the reviews and tried it out. I sprayed the whole house before she came over, and she was completely fine. What kind of magical juice is this???...

Frequently asked questions

What are allergens?

Allergens are substances that can cause an allergic reaction. The most common allergens are proteins found in dust mites, pollen, mold, dust, and animal dander. When these proteins come into contact with the mucous membranes of the nose or eyes, they can trigger an immune response. The body produces antibodies to fight off allergens, which can lead to symptoms such as sneezing, watery eyes, and a runny nose.

How does the spray actually work?

Our unique mixture activates with water, and when atomized in a spray, attracts and attaches to allergen molecules and proteins in the air and on surfaces where they bring them down, encapsulate, and neutralize them- all with minerals.
