My daughter didn't sneeze!
Every time my daughter would come visit our home, our 2 cats would make her sneeze. I tried the Pacagen spray on all the areas the cats like to lay (rugs, couch, chairs, etc.) and after only a few times, she said she felt much better. No more sneezing! I'm a believer!!

Fantastic product that really works
We had a person stay over for 3 nights in our house with 2 Siamese cats. She is highly allergic to cats. Not a sniffle, sneeze, itchy eyes. NOTHING! Miraculous.

It works!
Thanks to this spray I was able to have my friend over who previously couldn't visit without severely watery eyes. Now she can comfortably sit on my couch in the same room as my cat!

It worked!
My grandchild and son-in-law, both of whom are allergic to cats and are always uncomfortable in our house even with taking medication, spent ten days in our house with NO symptoms and without their meds. I sprayed before they arrived and every other day while they were here and never heard a sneeze or saw a teary eye.

Great product
I have 2 cats that I love, but one of them gives me allergies, and between seasonal and cat allergies I was dying, sneezing, coughing and swollen eyes :( but after a few weeks using this product my life has changed, no more sneezing and overall no more red, swollen eyes.

Works for 4 Cats!
You can hot mop your hard surfaces which helps but I was losing to the soft surfaces. Pacagen made a huge difference. It actually works. I love my cats. Pacagen has relieved quite a bit of allergies and stress. I don't worry about what to do if my kids have allergy. I feel confident no one will be shipped off to grandma's house over cat dander

An actual life saver!
I've used Pacagen for about a month now and have definitely noticed a difference in my allergies around my house. I like that the spray helps me target specific areas of the house, and compared to some other dander reducing sprays, has no strong invasive smell. The bottle is still going on strong and I'm happy to be more comfortable around my house!

Surprisingly works
My spouse has severe allergies to cats but loves them. With this spray we can sleep with our two cats in our bed and she can sleep through the night with no issues.

Finally relief!!!
My partner has a cat and I couldn't ever go to their place. But not anymore! I bought the starter pack and walked into the apartment spraying everything. It went so well that I'm at their place all the time now. I can even tolerate the cat sleeping on the bed with us. This stuff is a game changer and I highly recommend!!!

Amazing life saver.
It really helped my sudden eczema reaction caused by cat allergens immediately. Life saver. This is enabling me to keep my fur babies, even in a studio where my cats often sleep with me. I take the spray to my friends' place with cats too and I can hang out just fine. Thank you!

Incredibly Helpful
I have only been using Pacagen for a short while and have already noticed a difference in my allergies. Use of Pacagen in combination with increased vacuuming have led to a noticeable positive effect when I use the spray and I have stopped having issues with rashes and stuffy noses caused by allergies to my cat.

Us vs. Them

Relief is just a spray away

Over 50,000 Allergen Free Households And Counting
how it works

Households commonly contain high levels of major allergens - Fel d 1, Can f 1, and Der p 1. These microscopic particles are what cause allergies.

We engineered WhiskerBlock & EnviroBlock, both of which can bind to and neutralize these major allergens!

We added WhiskerBlock & EnviroBlock into sprays for easy use. Simply spray in the air and on surfaces every 2-3 days.

The result? Major allergens are neutralized, which means less stress and sniffles!
FAQs
Definitely! We made sure to use a completely pet-friendly approach when creating our formulas. Each part of the formula was hand-picked to be safe for everyone, four-legged or not, involved. However, it’s best to avoid spraying directly onto cats – mainly because cats usually don’t like getting wet. On top of that, WhiskerBlock & EnviroBlock are always manufactured to food-grade standards.
WhiskerBlock & EnviroBlock, being proteins, are by nature subject to degradation when dissolved in tap water, as minerals and impurities can disturb their structure. The Stabilizing Solution is formulated to preserve their structure as long as possible without hampering their neutralizing properties.
We carry a lightly fragranced (Floral Breeze) and a fragrance-free (Natural) version of the spray. The Floral Breeze scent is very mild and most customers report that the scent is close to unnoticeable after spraying. The fragrance-free formula was developed for those who are extremely sensitive to specific scents (i.e., Morning Glory Scent and English Lavender Scent).
Our products use the latest developments in biotechnology to provide you with a safe, pure, and environmentally friendly solution. Internal testing has found that WhiskerBlock is capable of neutralizing up to 98% of Fel d 1, and that EnviroBlock is capable of neutralizing up to 76% of Der p 1 enzymatic activity.
While undissolved, the Allergen Neutralizing Powder doesn't expire, but it is most effective within 1 month of dissolving in distilled water. However, if you dissolve the Allergen Neutralizing Powder in our Stabilizing Solution, it'll be effective for up to 2 months.
Spraying frequency depends on a lot of factors, including the concentration of airborne allergens, how severe your allergies are, and how sensitized your immune system is. We recommend starting out by spraying once every 2 days, then increasing or decreasing the frequency depending on if your symptoms are still present.
We take pride in the fact that our sprays are designed with environmental consciousness in mind. Where possible, we use biological ingredients that have no long-term environmental impact. In fact, 99% of the ingredients in the powder are biodegradable! We also make sure that all of our partners share a similar commitment to environmental consciousness.
For orders within the contiguous United States, we offer 3-day and 5-day shipping options. To Hawaii & Alaska, orders can take up to 8 days to arrive. For orders to Canada, please allow up to 10 days for shipping, as CBSA processing times vary.
