How Long Can My Dog Wear the K9 Mask® Using an Air Filter?

  • We recommend using each air filter up to four hours. However, depending on large particle air conditions, moisture levels, or excessive dirt in the filter it might be necessary to replace the air filter sooner.
  • Prolonged use can affect a dog's natural ability to cool itself through panting especially at temperatures of 80°(F) 26°(C) or higher. This mask is intended to be used for a short duration and under close supervision. Be cautious using for more than 10 minutes (N95 Extreme Breathe) or 30 minutes (Clean Breathe) at a time. After 10 or 30 minutes you may remove the mask for several minutes to check the breathing and panting of your dog then continue wearing the K9 Mask®.
  • Always visually monitor your dog while wearing the K9 Mask®. If you notice labored breathing or signs of overheating remove the mask immediately. This mask may cause injury or death to your dog.

Will the K9 Mask® Work as a Muzzle for My Dog?

  • The K9 Mask® does work as a muzzle. This is a secondary purpose for the K9 Mask. The primary function of the mask is to protect the dog from air pollution.

K9 Mask® Air Filters are Independently Verified for Effectiveness?

  • K9 Mask® air filters have been certified by Blue Heaven Technologies in Louisville, Kentucky, USA with an ISO 16890 (International Organization for Standardization) air filter test.

How to Insert the Air Filter into the K9 Mask®.

Open the zipper on the top of the mask. Insert the air filter into mask with the dark side on top and white side on the bottom. Place the curve edge of the filter facing the nose of the mask. Align the air filter inside the mask so all edges of the air filter fit against the sides of the mask. Close the zipper on the mask.

How to Secure the K9 Mask® on a Dog's Muzzle to Keep Polluted Air from Being Inhaled.

K9 Masks® are effective when they are worn properly. Using the K9 Mask® muzzle adjustment under the snout of a dog a pet owner is able to adjust the tension on the mask to significantly reduce polluted air from leaking into the mask. This ensures only air passing through the air filter is being inhaled by the dog.

How Do I Train My Dog to Wear the K9 Mask®?

Training your dog to wear the K9 Mask® involves pairing a positive stimulus with wearing the mask.

  • Present the mask to your dog and let the dog smell it.
  • Try adding a snack treat inside the mask for your dog to sniff and retrieve. This process gives a positive reinforcement about the mask.
  • Try putting the mask on your dog’s muzzle for a few seconds, while giving verbal affirmation to your dog, to acclimate it to the mask.
  • Repeat this sequence several times, working towards securing the mask in place around the dog’s neck and muzzle using the hook and loop tabs.
  • Provide positive verbal feedback to the dog about wearing the mask.

How to Choose the Right Size K9 Mask® for a Dog

K9 Mask® Sizing Chart Fit Guide for Dog Air Filter Face Gas Mask
    • The crucial measurement to determine the appropriate size is the Muzzle Circumference.
    • If a flexible measuring tape is unavailable, a shoelace or phone charging cable can serve as a makeshift alternative for taking measurements. Subsequently, use a ruler or a metal measuring tape to obtain the accurate Muzzle Circumference size.
    • In instances where your dog falls between two Muzzle Circumference sizes, we advise opting for the larger size mask. This choice provides additional panting space within the mask, ensuring both comfort and effective use for your dog.

    Caring for Your K9 Mask®

    • Hang the mask to air dry.
