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 dogs. On top of that, WhiskerBlock is always manufactured to food-grade standards.

WhiskerBlock, being a protein, is by nature subject to degradation when dissolved in tap water, as minerals and impurities can disturb its structure. The Stabilizing Solution is formulated to preserve WhiskerBlock's structure as long as possible without hampering its neutralizing properties.

We don't currently make a scent-free version. However, the scents included in our Allergen Neutralizing Powder are very mild and are included in very small quantities. Most customers report that the scent is close to unnoticeable after spraying.

Our products use the latest advancements in biotechnology to offer a safe, pure, and environmentally friendly solution to your allergies. They seamlessly integrate into your routine and are non-invasive for both you and your pet.

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 how much Can f 1 and Can f 2 your dog produces, 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.

As Featured In

how it works

Dogs produce allergens called Can f 1 and Can f 2 in their saliva, which are what cause dog allergies.

We engineered WhiskerBlock that can bind to and break down these dog allergens!

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

The result: Can f 1 and Can f 2 are neutralized, which means less sniffles and more cuddles!

how to use it

Find areas in your house that dogs frequent, such as the couch, the bedroom, or near their bed.

Spray these areas generously with our Allergen Neutralizing Spray and wait 10-15 minutes for WhiskerBlock to work its magic.

Repeat this process every 2-3 days based on symptoms to enjoy your newly discovered dog allergen-free life!

the science behind pacagen

Our search for a better way to manage dog allergens began with an unexpected key player: alpacas! Inspired by their unique immune systems, we developed WhiskerBlock that has the remarkable ability to exclusively bind to Can f 1 and Can f 2 without affecting dogs or people.

Through a binding mechanism only possible because of WhiskerBlock's unique structure, our products are able to reduce airborne Can f 1 and Can f 2 concentrations, making it the most effective dog allergen reducer available.

A story rooted in love

Pacagen’s journey began with love at first sight. When Dr. Evan Zhao and Dr. Siyang Han welcomed their British Shorthair, Miaomiao, into their lives, their joy was quickly met with a challenge—Siyang’s allergies. Determined not to choose between her health and Miaomiao, Evan, a Ph.D. in Chemical Engineering from Princeton University, turned to his expertise. The discovery of WhiskerBlock provided the answer.

The result? A cat allergen spray, safe for pets and people. “Now, we can enjoy Miaomiao without worry—and that’s what I want for every pet family,” Evan shares.

the love story continues

WORTH IT!!!!!

Literally within 2 hours of spraying, my itchy eyes stopped being itchy and I stopped sneezing like an old man. My girlfriend moved in with me 3 weeks ago and brought her dog Lola. Never knew I was allergic before but have been struggling for the better part of a month. Works like a dream - no clue what we'd do without...

Was Skeptical But Wow

We got a corgi puppy for our daughter after she's been asking for years only to realize that her older brother is allergic. Frankly was skeptical this would work but I couldn't give the puppy away so I was pretty desperate. Ordered this as soon as I saw it and honestly we saw my son's itchy eyes and scratchy throat stop by the end of the first day. Super easy to use, doesn't bother the puppy, and I have peace in my house again. Totally worth the try!

Works surprisingly well!

My husband heard about this spray from a friend and thought it'd be perfect since I recently started getting allergies around our new puppy. We haven't been using it for too long yet, but I can already tell it makes a HUGE difference! I will keep using it and update, but for now it's working just as good if not better than the meds i used to take (which btw I don't have to use anymore).
