Science is our pet subject

Cat and dog allergies are triggered by pet hair, dander and the microscopic life that lives off it. To discover how to prevent pet dander from spreading around the home, Dyson’s microbiologists have spent years studying how pet allergens work.

How a Dyson deep clean can help

Allergens in pets can become airborne and settle throughout the home, thanks to the lightweight statis of pet hair. Alongside the potential of cat or dog allergies is bacteria and dirt brought in from outside by your pets. Dyson’s vacuum and air purifier technology helps to control pet allergies, through powerful suction and advanced filtration.

Your pet drops hair and particles as small as allergens around your home

Pet hair may be visible, but the microscopic allergens they carry aren’t. To protect the health of homes, Dyson’s engineers studied how pet allergens work and move with hair. Take a closer look below.

    Dyson knows pet hair

    From German Shepherds to Samoyeds, Dyson’s scientists understand how different hair and accompanying pet allergens move, bend and fall.

    And how to remove it

    The Dyson Motorbar™ cleaner head technology drives stiff nylon bristles deep into carpet to capture stubborn hair.

    Dust and hair can also cling to the static charges in hard floors. Anti-static carbon fibre filaments reach deep to release fine particles and help reduce cat and dog allergies.

Powerfully captures pet hair

The Dyson Motorbar™ automatically de-tangles. Powerful Dyson suction removed dust, dirt and pet hair.

    At how to prevent pet dander

    Saliva, dead skin and mites are all attached to pet hair, causing instances of cat or dog allergies.

  • Particle becomes visible under microscope

    For a cleaner, more hygienic home

    That’s why Dyson vacuums have the tools, power and filtration to capture and contain invisible particles.



Only advanced filtration can help remove pet hair allergens from the home. Dyson vacuums trap 99.99% of particles as small as 0.3 microns2. Our latest HEPA vacuums have a filtration efficiency of 99.97% down to 0.1 microns3, helping you capture invisible dust.
