Our Mission

The allergy industry profits from your symptoms.
Aeroguard eliminates the cause.

The allergy industry profits from daily pills and shots that mask symptoms. AeroGuard is built on a different premise: our biotechnology targets the source, not just the symptoms.

AeroGuard was developed by Harvard scientists who spent years studying the specific proteins that cause dust allergies — DER P 1 and DER P 2. The result is a precision formula that has been independently lab-tested for safety and efficacy. Designed to work with your body's natural processes, not override them.

The Science

The DER P 1 Difference



Over 90% of dust allergy reactions are triggered by just two proteins found in dust mite waste: DER P 1 and DER P 2. Most treatments ignore them entirely, but our patented AeroBlock technology binds directly to DER P 1 and DER P 2, neutralizing them on contact. Just one spritz for 24 hour protection.
