AeroHippus* Equine Aerosol Chamber

The AeroHippus* Equine Aerosol Chamber (EAC) is designed to be used with a pressurized metered dose inhaler (puffer) as recommended by a veterinarian to deliver aerosol medication to horses with respiratory diseases such as Inflammatory Airway Disease or Recurrent Airway Obstruction. When the AeroHippus* EAC is attached to the puffer it allows your horse to breathe normally and inhale the aerosol medication so the medication goes deep into your horse’s lungs where it is needed.


The Flow-Vu* Indicator will help you count the number of breaths your horse has taken through the chamber and may help to ensure there is a satisfactory seal between the muzzle and the mask, to optimize delivery of the medication. As your horse inhales, the bright green Flow-Vu* Indicator will flutter or move towards the horse (if you have a good mask seal). When the horse stops inhaling or exhales, the indicator will return to the vertical position.


The ideal time to activate the puffer is when your horse starts to inhale and the Flow-Vu* Indicator is moving horizontally towards them.

    Respiratory diseases in horses are often classified in two ways: Inflammatory Airway Disease (IAD) and Recurrent Airway Obstructions (RAO)
  • Horse and foal grazing.
    Inflammatory Airway Disease (IAD): Chronic, intermittent cough, increased mucoid airway secretions, and decreased performance. IAD can affect horses of any age and clinical signs at rest are usually subtle.
  • Horse coughing.
    Recurrent Airway Obstruction (RAO): Disease of the lower airways, resulting in coughing and exercise intolerance. RAO tends to affect mature to older animals and may also be referred to as Heaves.

  • “The mask worked wonderfully. He received medication for three weeks and became quite used to the mask. I think he figured out that it made him feel better. Hopefully, I won't have to use it very often, but it is nice to have on hand and it's portable, so I can carry it with me. I am thoroughly pleased with your product.”

  • “Our mare was diagnosed with heaves a few months after the delivery of her foal. The veterinarian said that she would need to use Flovent and Ventolin for several weeks along with a mask. The AeroHippus* EAC has been such a blessing and we do not hesitate to recommend it. We are pleased with how quickly our mare responds to treatment using the AeroHippus* EAC. It is extremely quick and easy to use. In our opinion, it is a less intrusive treatment than one where an apparatus is placed over the entire muzzle. Our mare has now weaned her foal and we anticipate that she will begin showing this fall. We are confident that, should she have an episode at the barn or during a show, we will be able to handle it.”
