  • With allergens neutralized, you can relax in a healthier home.

    • Its only been 7 days and I feel so much better

    Relief!

    I was skeptical trying this but figured it was worth a try. I have two beagles that shed constantly — I’d wake up stuffy and with sinus pain regularly. Since using Pacagen every few days, I have notably less sinus pain and issues. So thrilled and will continue using it!

    No more morning sneezes

    In our home we have a schnauzer mix who sheds a lot. He sleeps with me, and I used to wake up sneezing, not anymore! My morning sneezes, itchy eyes, and phlegmy cough are gone! The air in my apartment feels lighter too. LOVE this product!!!!

    It works!

    My mom always gets itchy legs and watery eyes when she visits (known dog allergy). I sprayed this the morning before she arrived and every few days while she was here. No itchy legs, no watery eyes! She even was able to lay on our fabric couch with no issues!
