Using 2-3x a week made a real difference in my home
I’ve been using Pacagen allergen neutralizing spray consistently 2-3 times a week, and I can honestly say I’ve noticed a difference in my home environment. I have 2 cats, and as an allergic person, pet-related allergens have always been a concern for me, especially with shedding and dander. The spray itself is very easy to use, just a quick even application on surfaces like furniture, bedding, cat tree and areas where my cats spend the most time. It does not leave any strong or overwhelming scent, which I really appreciate, and it dries fairly quickly without residue. And also it is pet-friendly. After a couple of weeks of regular use I felt like the air was “lighter” and I wasn’t reacting as much as I usually do. It’s not a magic fix, but as part of a routine (along with cleaning and brushing my cats) it definitely helps manage allergens better. Overall, I think is a safe and solid option if you’re dealing with pet-related allergies and want something simple but efficient to add to your routine without a lot of hassle.

Actually made a noticeable difference for my cat allergies
I’ve been meaning to write this review for a while because this is one of the few products that has actually made a noticeable difference for me. I live with my cat in a smaller space, so allergens tend to build up quickly — especially on fabrics and in the areas she spends the most time. I have mild cat allergies, and usually I’ll feel it pretty fast (itchy eyes, congestion, etc.). After using Pacagen consistently, I genuinely noticed a shift. It didn’t feel like I had to constantly manage my environment in the same way anymore. What I appreciate most is how easy it is to incorporate into a routine. The setup is simple, and once it’s mixed, I just spray it around my apartment every few days — mainly on my couch, bedding, and her favorite spots. There’s no strong scent, no residue, and it doesn’t feel harsh or chemical-heavy, which was really important to me. I was also very cautious about using anything new around my cat, but she had zero reaction to it. No irritation or avoidance — she acts completely normal, which gave me a lot of confidence in continuing to use it regularly. It’s definitely an investment, but for me, it’s been worth it to feel more comfortable in my own space without constantly worrying about allergy flare-ups. If you’re someone who loves your cat but struggles with allergies, this is absolutely worth trying.

Takes edge off allergies; no scent
I was worried this would have a smell and aggravate my allergies but I didn’t notice any scent. The packages mixed together well, and the bottle sprayed easily without clogging and is fine enough to mist the air. It is hard to tell how much it helps, but it does seem to take the edge off allergies to the cat. There is an expiration after the parts are mixed, and it must be stored in the fridge to last longer. I will likely try again to see how continued use over time works and if I notice a significant change after stopping. The company has great customer service, and it’s good to support a small business instead of any large corporation selling similar products. It is a bit pricy, which could be a deterrent, especially over time.

Easy to use. Works well!
I’ve been using the Pacagen cat allergy spray for a bit now, and it’s been surprisingly helpful. It’s easy to apply and after consistent use I noticed fewer allergy symptoms like sneezing and itchy eyes. My cat doesn’t mind it, and there’s no strong lingering smell, which makes it easy to stick with! It’s not a complete fix (especially for more serious allergies) but it definitely helps reduce symptoms. A simple, low-effort way to make living with a cat more comfortable if you have mild to moderate allergies.

Actually works! My wife can finally cuddle our cats without the sniffles
We have three cats (Bean, Mochi, and George) and my wife has mild allergies to cat hair. She's been dealing with the sniffles pretty much daily, especially after cuddling with them. We tried the Pacagen spray and noticed a difference fast. She's been way more comfortable since we started using it, which has been a game changer for our household. A few things that stood out to us: - It's super easy to use. Just spray and you're done, no deep cleaning required. - It actually smells nice. We were worried it would be harsh or chemical-y, but it's pleasant. - Our cats didn't mind it at all. No weird reactions, no avoiding the sprayed areas. That was honestly the thing we cared about most. If you're a cat parent dealing with allergies (yours or someone in your household), this is absolutely worth trying. It does exactly what it claims to do and fits easily into your routine. Highly recommend.

Working I think and very happy
Honest review!! Currently giving this a 4 star review because I am 95% certain it’s working! My boyfriend has severe cat allergies to where his eyes water quickly when he’s here no matter the air filter and how clean I keep the house. After I’d say 2 weeks of treatment I think I’m beginning to see a difference for him. He has lasted longer and his eyes itch SIGNIFICANTLY less. No more red eyes for him which is a huge relief. I spray it for the treatment plan 2x a week and before he comes over I will spray the high cat areas. I hope this helps for anyone curious, I took the plunge and it seems to be helpful so far. To be continued!

Great spray in addition to frequent cleaning!
Spring is always the worst for my allergies and having a cat on top of that sends me for a spiral. But after using this spray for a few weeks, my partner and I have noticed a significant difference in our home. We noticed less sneezing, congestion, and could sleep comfortably at night. For the best results, be sure to sweep, vacuum, and mop every week! We love this stuff and will be back for more when we go through our bottle.

Works wonders
I didn’t have any doubts but I was pleasantly surprised by how fast this works! One of my cats fur usually makes me itchy, plus have itchy watery eyes. I go to sleep and wake up with itchy watery eyes too and the last few days I haven’t had that at all. I also love that it’s odorless, doesn’t make the surface you spray it on “wet” and leaves no residue because I was also concerned my cats might try to lick it but they didn’t. They were not bothered by it all both tolerance wise and healthwise! Also super easy to put together instructions were super clear but also extremely easy to assemble. I like that I didn’t have to do anything of my own like add water or buy my own spray bottle. 20/10!!

It works!
My son suddenly became allergic to our cats, and it got so bad he could barely breathe and had to take allergy pills — even though we’ve had cats for years. I tried this spray for a few days, and it actually worked! It’s super easy to use — just spray it around the spots the cats going out and my son’s room. After only two days, his symptoms got way better. He didn’t need pills anymore and could breathe freely again. So amazing!

I’ve spent thousands and this is the only thing that’s showing promise
My boyfriend had been suffering for over a month trying to get used to my cat, since moving my cat in. We tried 2 different attempts at moving my cat in but had to bring him to my moms after a month each time because my partners allergies were so bad. He couldn’t breathe, couldn’t sleep, couldn’t work, and had to cancel clients (tattoo artist, dripping/sneezing nose into broken skin, can’t breathe = very unsterile and a quick way to get your shop shut down. Can’t risk it). He has lost thousands of dollars because of this. He was on meds and sprays constantly. He was miserable, and this was all while having a cat free bedroom, a Blueair 211i HEPA purifier in the living room, two more purifiers in other rooms, and my cat being wiped down/brushed, dry shampooed/literally bathed often. My cat was already on purina LiveClear for a year. He has pine litter so it doesn’t track. His litter box is sifting and enclosed, inside another small tent-like enclosure to ensure particles don’t go far. His droppings went into a litter genie so it was trapped. I was diligent about sweeping/mopping/dusting/disinfecting and wiping down surfaces… none of it was working. I was doing all the right things. We had all the right furniture - no carpet, leather couch, no drapes, no cat tree, washable bed for the cat, cat free bedroom, etc. Partner was miserable, and I couldn’t stomach moving my cat yet again.. so it was beginning to look like i either had to end the relationship or give away my baby. I got this spray in 4 days ago, and I’ve been using it daily to start in the common rooms and even the cat free bedroom. My boyfriend is no longer struggling to breathe the way he was. He isn’t using his sprays nearly as often, and he hasn’t taken a med. And he hasn’t missed work or cancelled a client. I pray to god this is a continual thing and not a fluke. I’ve spent thousands of dollars on trying ti manage this. The only thing that’s changed is this spray. Will update in the next month. This might be the ticket to keeping my cat and my relationship. I’m holding my breath 🙏 I initially accidentally bought the dust spray.. which I didn’t know, and I went to request a refund as I thought my “cat allergy” spray (which was actually the dust spray) wasn’t working…. and that’s when I was notified I ordered the wrong thing. the customer service was excellent and they really helped me, quickly.

Works quickly
I'm mildly allergic to cats and had a cat stay over for a while recently. Been sneezing none stop since the cat left :( thankfully this spray worked very quickly with just a couple spitzs all over my furniture. The powder and liquid mix has a strong smell to it, but after its mixed up it doesn't smell like much anymore. The bottle says good for 1 month after mixed and 2 month if refrigerated, so I only mixed a portion of it to prolong the usage time.
