We first began using the FlexiNeb Equine Nebulizer when one of our good open horses developed a respiratory infection. After a thorough diagnosis and treatment plan, we worked closely with the veterinarians at Cornell University to research the best equine nebulizer to use for his treatment. The small particle size produced by the FlexiNeb Equine Nebulizer allows the medications to reach deeper in to the alveoli of the lungs than other nebulizers. After purchasing it, we found that it was simple to use with no hoses and quiet operation. We now use it to nebulize saline before and after our runs to keep our horses feeling and running great.
