Pacagen works, so you don't have to.
We didn't just stumble upon a solution; we developed it because we needed it ourselves!
Pacagen: The Modern Allergen Solution
Until now, treating allergies has been all about suppressing your body's reaction. Pacagen works in your home environment. Not your body.
Why it works
Most allergy solutions focus on your immune system after it's been triggered ... think allergy pills & nasal sprays. But here's the truth:
The real culprit is in your environment - tiny proteins from your pets, dust mites, or pollen that your body mistakes as threats.
That’s why we took a different approach.
We invested $2 million dollars into developing WhiskerBlock™ to tackle the problem at its source — we solve the problem before it manifests.
So, what does this mean for you?
No drugs.
No doctor’s prescriptions.
No side effects.
Because Pacagen works in your home - not your body.
In the heart of the Andes, Alpaca’s thrive in part thanks to a unique immune adaptation.
They produce single-domain antibodies: tiny yet powerful proteins that block foreign threats, like bacteria and viruses.
We took this concept and reimagined it to household allergens.
Instead of altering your immune system like antihistamines or nasal sprays, Pacagen targets allergens right at the source – in your environment.
We developed WhiskerBlock™ after testing and refining millions of proteins through precise protein engineering to find the most specific and safe solution for real homes.
The result? A scientifically advanced, non-invasive way to control allergens before they ever reach you.
WhiskerBlock™ isn't a drug. It's a new kind of clean. Use it to make your home hypoallergenic again.
• Deactivates up to 98% environmental allergens.
• Full efficacy is achieved as fast as 20 minutes.
WhiskerBlock™ passed rigorous safety tests across pets, humans, and homes.
✅ Safe for kids, pets, and sensitive skin
✅ Works on any surface: couches, carpets, bedding, and more
✅ No harsh chemicals, neutral scent
Why does safety matter? Because when something is safe enough for daily, worry-free use, it becomes part of your routine - and that’s what makes it truly effective.
WhiskerBlock™ isn’t a drug. It’s a new kind of clean. Use it to make your home hypoallergenic again.
Some allergens like Der p 1 not only trigger allergies, but also biologically worsen it.
EnviroBlock is designed to deactivate the allergen AND block this bioactivity.
Besides superior deactivation, EnviroBlock also blocks up to 93% of Der p 1 bioactivity — managing allergies in both ways.
No pills to remember. No clinic visits.
Simple to use: Mix, shake, and spray.
Pacagen gives instant reliefs, you can see effects in weeks and even hours.
Pacagen maintains your house hypoallergenic, no running nose, no congestion, no difficulty breathing for everyone.
We are not satisfied with lab results only, Pacagen’s unmatched safety is well supported in daily lives.
No need to choose between comfort and easy breathe — you deserve both.
