How We Defend

Defend Your Space: Allergen Spray

Because the major indoor allergens of concern—specifically cat dander (Fel d 1), dog dander (Can f 1), and dust mites (Der p 1, Der f 1)—are protein-based, our non-protein mineral formulation offers an inherently inert, hypoallergenic foundation unlike anything on the market today. It's a Breakthrough in mineral-based environmental control, delivering a clean, stable, and highly targeted way to reduce allergen exposure without introducing new biological triggers.

Independent laboratory analysis conducted by Indoor Biotechnologies, using the validated MARIA® (Multiplex Array for Indoor Allergens) assay, confirmed the performance of this system:

Up to 95% reduction in airborne allergen concentrations within a controlled environmental chamber

Up to 99% reduction of surface-bound allergens across multiple standardized assays

These results were observed for the major indoor allergens tested.

Mechanistically, the formulation works by rapidly binding to, immobilizing, and neutralizing protein-based allergen molecules upon contact. This process significantly reduces their bioavailability and prevents them from re-entering the air or redistributing throughout the home.

Real Science, Real Results

Powerful Air & Surface Reduction

  • 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 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.

  • Who is Inbio?

    Inbio is recognized as the world leader in allergen exposure assessment

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

  • Testing Method

    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. 

* Both statements apply to the allergens tested, which are representative of the variety of clinically relevant indoor allergens known to contribute to the development and exacerbation of asthma and other allergic conditions.

Indoor Biotechnologies is committed to providing its customers with the highest quality products and services and recognizes the importance and value of an established Quality Assurance program. Indoor Biotechnologies' Analysis Services Laboratory is ISO/IEC 17025:2017 accredited for allergen testing (Perry Johnson Laboratory Accreditation, Inc. Accreditation No.: Certificate No.: 76453. L20-587).

Powerful Ingredients

Mineral Protection

  • Why Minerals?

    Allergic reactions are triggered by proteins — not particles, not dust, not “dirt,” but the microscopic proteins found on things like dog and cat dander, dust mites, pollen, and many plant-based materials. These proteins are what your immune system recognizes and reacts to.

    Minerals, however, contain zero proteins.

    They are elemental substances — meaning they do not have the biological structures capable of causing an allergic reaction.

    That’s why our Allergen Spray is built entirely from pure minerals. Without proteins, without plant extracts, and without animal derivatives, our formula gives families a cleaner, simpler, and safer base to use throughout their home.

    No proteins.

    No fragrances.

    No biologically reactive material.

    Just minerals — which makes our formula ideal for real homes with real sensitivities..

  • What is the Environmental Impact?

    Early in our development, we conducted a Lifecycle Assessment (LCA) — a scientific method used to evaluate the environmental impact of a product from creation to disposal. What we learned shaped every decision we made going forward.

    One of the largest environmental burdens in traditional cleaning and home-care products comes from shipping water. Water is heavy, bulky, and energy-intensive to transport, meaning it dramatically increases fuel usage, shipping emissions, and overall waste.

    That’s why we chose a different path:

    we ship only the concentrated minerals.

    No added water. No unnecessary weight. Just the active ingredients.

    This single choice significantly reduces our carbon footprint compared to conventional full-water spray bottles.

No harsh chemicals.

The Science Behind the Safety

We only use certified 100% food grade and FDA GRAS minerals. GRAS refers to substances that are Generally Recognized As Safe by the FDA. This designation is given to substances with a long history of safe use or that are safe through scientific study.

Our Allergen Spray never includes any harsh chemicals, petroleum-based ingredients, plant ingredients, fragrances, or essential oils.

Allergen Spray is the safest alternative for allergen control where human, animal, and food contact is likely.

Since even water can cause sensitivity to some people, we recommend stepping out of the room after spraying, allowing the allergens and dust to dry as they are pulled out of the air. 

How Our Spray Works

Pure Mineral Defense

  • The Ingredients

    Our Allergen Spray only contains ingredients listed by the FDA as GRAS (generally recognized as safe), meaning it is safe enough to be used in the foods you eat daily, like meat and dairy, and is used in water softening.

    Although these grades cost more, the additional purity of our ingredients provides an extra level of protection from possibly hazardous impurities that otherwise might be present.

    Our Ingredients: FDA & GRAS pure sodium sesquicarbonate, FDA food grade mineral phosphate salts.

  • How Our Spray Works

    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, neutralize them- all with minerals. This creates an invisible protective barrier that prevents allergens from escaping, reducing exposure and creating a cleaner and more allergen-free living space.

    Because the product is combined with water to such an extent, its inhalation does not produce skin or lung irritation, has no dry particulates and is perfect for contact internally and externally when used as directed.

  • Family Safety

    This formula was originally created by my father, and a team of chemists, for our own family. From the beginning, he approached it with care—focusing on simple, well-understood ingredients and how they behave in everyday indoor environments, without adding unnecessary substances to the spaces families rely on most. It was designed to remove particles from the environment, not introduce anything new.

    Inactivation Without Irritants
    Many allergen products rely on enzymes, essential oils, or synthetic chemicals, which can introduce new irritants or volatile organic compounds (VOCs). Minerals are non-reactive to the human body, free from VOCs, and fragrance-free, ensuring neutralization without the risk of added sensitizers.

  • Pet Safety

    Developed by pet owners, the formula was created with firsthand understanding of the realities of living with animals indoors. The formulation intentionally excludes harsh chemical agents, added fragrances, plant derivatives, and essential oils, which are commonly associated with environmental sensitivity in both human and pets. Thousands of pet owners trust Allergen Spray in their homes—including ours.

How We Support

Support Your Body: Defender Supplements

We believe comfort goes beyond clean air — especially when seasonal changes, environmental triggers, or everyday stress challenge your body’s balance. That’s why our supplements exist.

EnviroDefender

Designed for daily support, EnviroDefender is formulated with carefully sourced ingredients including quercetin, bromelain, nettle extract, NAC, Vitamin C, Vitamin D3 and zinc. These nutrients work proactively: instead of only treating symptoms after they occur, EnviroDefender supports your body before triggers arrive.
The idea: give your system a buffer — so when pollen, pet dander or dust enters your day, your body is better prepared to respond without overreacting.

HistaDefender

Some sensitivities come from histamine — either from foods, environmental exposures, or internal reactions. HistaDefender DAO is formulated to help support natural histamine-processing where it begins: the gut.

It contains DAO (diamine oxidase), an enzyme that supports histamine breakdown in the digestive tract.

It also includes antioxidant-rich pine bark extract, catalase, and Vitamin C to support overall gut balance — because histamine sensitivity often starts internally, not just from external allergens.

DetoxDefender

Modern life exposes us to many environmental stressors — from airborne particles to everyday toxins. DetoxDefender is formulated to support the body’s natural detox pathways (Phase I & II), helping process and clear environmental exposures, excess histamine, and other stressors.

With ingredients like milk thistle, watercress, artichoke, green tea, and herbal extracts, DetoxDefender supports your liver and detox systems to help maintain internal balance.

For those sensitive to environmental changes or frequent exposure to allergens, DetoxDefender offers gentle ongoing support — helping your body reset more steadily even when triggers are unavoidable.

Together, these supplements form a three-step internal support system: prepare the body (EnviroDefender), support histamine processing (HistaDefender), and help the body clear and reset (DetoxDefender).

How We Restore

Restore Your Body: Magnesium Spray

Magnesium is one of the most widely studied minerals in the world, with tens of thousands of published scientific papers examining its role in human physiology, stress response, muscle function, sleep quality, and overall wellness. It’s an essential mineral involved in hundreds of biochemical reactions in the body, and its importance has been documented across decades of peer-reviewed research.

What matters most for us — and for families navigating allergies, asthma, or environmental sensitivities — is that magnesium plays a key part in how the body winds down, relaxes, and restores, especially after a long or stressful day.

That’s why we made magnesium an essential part of the Defender System.

Our topical magnesium is:
Fragrance-free
Gentle and non-irritating
Clean and simple — just the mineral, no unnecessary additives
Designed for people with sensitivities in mind

Environmental triggers and daily stress can weigh heavily on the body. Magnesium gives you a way to support your evening routine with a mineral that has been extensively researched for generations.

This is the restore pillar of the Defender System — supporting calm, comfort, and the nightly reset your body depends on.

What This Means for You

By adopting the full Defender System — spray, supplements, and magnesium — you’re not counting on luck or hoping for “one-size-fits-all.”

You’re giving yourself a thoughtfully built, multi-layered defense program that:

Reduces environmental allergen load in your home. Supports your body’s natural ability to respond to triggers and maintain balance. Helps your body rest, recover, and stay resilient

This is the kind of holistic care I wish I had when I was growing up. Now I’m proud to make it available to you.
