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.

    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.

    Saved me!!

    I have several recently developed health issues that preclude me from getting allergy shots or taking many allergy medications… so Pacagen saved me from having to get rid of my Maine Coon. He is a great companion and it would have completely wrecked me if I had to rehome him. Thank you Pacagen!

    good to have on hand

    I had a bottle at the ready since I am bedbound with severe ME as well as MCAS which is a mast cell disorder that can release excess amounts of histamine and other things you do not want in your body as it can make it painful and exhausted.

    I was adopting a cat that I could not meet completely alone with without dealing with the dander of 30 other cats at the same time, so the true test would unfortunately be bringing her home.

    I was itchy the first few days, but only about three out of 10. My caregivers sprayed pacagen a few times and I could definitely feel it. Bring the entire intensity of the itch down. I don’t know what happened if my medication (ketotefin) kicked in even more though I was taking half the usual amount, but now I am not itchy at all!

    I wouldn’t have attempted this Adoption without having pacagen, and I’m very grateful that I had it in my back pocket and then it did take the edge off and that now somehow I don’t even need it anymore!

    Great Product

    We have a family member with us now that has a cat. While some of us have allergies to cats this product seems to work. We use it per the directions and so far so good! Thanks!

    Amazing product

    This spray has truly helped out within my home. My brother and his wife both have cat allergies and it's tough for them when they visit. We spray this a couple of days before they visit, and he can be around the cat with no issues whatsoever. She still eventually has a reaction, but it is a noticeable improvement

    Thank goodness this works!

    I married into a family where almost all of them have mild to severe cat allergies, including one kid with asthma and a severe reaction to cat dander. We have a sweet cat, but no one but me can touch her. Using the spray, we noticed an immediate difference. We just spray before anyone visits, or quickly once they're here, and there have been no reactions. No one has had to leave!
