Allergens & your home
Your environment is where the problem starts.

Allergens
They’re too small to see, but allergens are all around you. In the air, on your furniture, and even in your bedding. They often come from cats, dogs, and household dust, and while some people don’t react, for many of us they quietly build up — triggering sneezing, congestion, and irritation day after day.
You
Allergen
Symptom flare-up
Think of it this way:
It’s not just the outdoors or spring pollen causing problems — your own living space can be the biggest source of allergens. Even after you clean, these particles can cling to furniture, carpets, and fabrics.
Some allergens stay on surfaces for years.
Airflow units
Carpets & rugs
Soft furniture
(couches, chairs, etc.)
Curtains & fabrics
Bedding
(pillows, mattresses, comforters)
So, even with regular cleaning, allergens linger In your home. As contamination grows, your allergy symptoms remain.

Tackling allergies means understanding that your home itself is where the problem starts. The good news: there is a solution.

Why allergy pills aren't the real solution
Most remedies only help after the allergen enters your body - in which case, your body has already started to react.
When you breathe in allergens — like cat dander or dust — your body mistakes them for threats. It releases histamine, which triggers sneezing, itching, and inflammation. Allergy pills work by blocking histamine. But that only masks the symptoms once they've started, and daily medication often comes with side effects.
Now, imagine a world where your body doesn't feel threatened by allergens to begin with.

At Pacagen, we designed a way to make that possible.
The Pacagen approach.
Our journey began with a question:
What if allergy relief could start outside the body — at the source? That pursuit led us to an unexpected ally: the alpaca.
You might be asking
“How is that possible?”
Good question.
03
Inspired by Alpacas
Within the Alpaca immune systems lies a rare, elegant form of antibody known as a single-domain antibody — a protein so small, stable, and precise that it can be engineered to target allergens with nanoscopic accuracy.

We created our own technologies, inspired by alpacas' unique antibodies.
Through years of molecular design, testing millions of protein variations, and more than $2 million in research investment, we developed our proprietary ingredients.

The proprietary ingredients make it a scientifically advanced, non-invasive approach that finally control allergens before they ever reach you.

From Science to Spray
Every Pacagen product starts with rigorous science, but it ends with something far more personal:
... solutions that fit into real life,
created with care for both people and their pets.
Allergen Neutralizing Spray
A simple, non-invasive method to neutralize allergens at the source. Designed to spray furniture, bedding, carpets, or into the air. Spraying targets allergens directly and externally.



But innovation doesn't stop there...
Cat Allergen Reducing Supplement
Building on the same biological insight, we developed our simple yet powerful supplement. This formulation is safe and tasty, and it’s intended for cats. When ingested orally, your cats allergens naturally begin to neutralize — addressing the challenge at its true origin from the inside out.
Fight back against allergens.
