removes 98% of active allergens

Our revolutionary Cat Allergen Neutralizing Spray proactively shuts down particles that cause cat allergies.

How it works

Cats produce an allergen called Fel D1 in their saliva. This is what causes cat allergies.

Pacagen engineers proteins (called nanobodies) that can bind to and neutralize these allergens!

We put these nanobodies into sprays for easy use. Simply spray in the air and on surfaces every 2-3 days.

Purchased it for friends with cat allergies, and it's been smooth sailing. Simple to use, highly recommend since it eliminates the need for pills.

My girlfriend has severe allergies to cat hair (sneezing, running nose). The Pacagen spray actually works pretty well for her and along with some allergy relief pills, she’s completely okay to stay with our cat for a long time. Works great so far since I started using one month ago, hope it will be effective in the long run too!

A miracle cure to my cat allergies. Was never able to visit with my son & daughter-in-law who have two cats. Even with Zyrtec and Flonase I got itchy puffy eyes and face that lasted a day or two. With the addition of Pacagen, I was not only able to visit, but I actually slept in their home for 2 days/nights.

We do A LOT to mitigate cat dander—liveclear allergy food, HEPA air cleaners & vacuums, regular brushing, routine laundry, etc.—but I am always still suffering. [...] But bottom line is that I have noticed a significant reduction in my allergies since using this product.

I just got my first cat a few weeks ago. I was taking 2-3 allergy pills a day. Now after this product I'm taking 2-3 a week. It seems to be helping a ton. It is definitely worth a try if you experience allergies.
