Pacagen is a biotechnology company that works on ways to neutralize allergens, mainly the ones shed by pets, using spray technology of its own. The formulas are built on WhiskerBlock technology, which goes after allergens in the air and on surfaces and eases life for people with allergies. Dr. Evan Zhao and Dr. Siyang Han started the company, driven by a personal wish to improve the bond between owners and their animals. The business keeps up with advances in biotechnology so pet lovers can share a home with their animals without allergic trouble.
Its main product is a Cat Allergen Neutralizing Spray that is applied to surfaces and fabrics around the home. Products of this type are usually bought as a spray plus refills, since the allergen load in a house builds up again over time. Pacagen sells through its own website and through major online retailers, and shoppers can buy once or set up a subscription. Autoship refill orders ship free, while one-time orders carry a shipping charge that depends on the destination and the size of the basket, shown at checkout. PayPal, Google Pay and Apple Pay are all accepted.
Allergen products can come back within 30 days, and other items within 14 days, provided they arrived defective or the buyer was unhappy with how the allergen neutralizing products performed while following the guarantee terms. Refunds reach the original payment method within 10 business days, and a 30-day warranty applies. Digital gift cards run from $25 in denominations up to $300, and a Refer-a-Friend program lets customers pass a discount on to friends.
