    3. 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.

    4. How do I train my dog to wear the K9 Mask?

    Training your dog to wear the Pure Air X-1 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.

    5. Can I wash the K9 Mask? 

    • Yes, the exterior mask is washable. The replaceable N95 with PM2.5 air filters which you take in and out of the mask are not washable. Dogs tend to slobber when breathing or panting so we designed the K9 Mask to be washable to keep it fresh and clean for long-term use.
    • Note: Before washing the K9 Mask remove the air filter and exhaust valve. The mask may be washed in cold water with detergent and then hang to air dry. 
    K9 Mask Replacement Exhaust Valve Instructions
    To Remove Exhaust Valve:
    Start by holding the valve on the outside of the mask in one hand. With your other hand reach inside the mask and grab the center handle of the valve. Turn the valve on the inside of the mask counter clockwise to release it from the front of the valve.
    To Reinstall or Replace Exhaust Valve:
    Place the front of the valve on the front of the mask over the opening in the nose. On the inside of the mask insert the back of the valve onto the front valve by aligning the open tabs on the front valve with the extended plastic tabs on back of the valve. Twist the back of the valve on the inside of the mask clockwise to lock the valve into place.

        6. 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.
        • WARNING: Designed for temporary use only.
          • Designed for temporary use only. Prolonged use can affect a dog's natural ability to cool itself through panting especially at temperatures of 80° (F) or higher. This mask is intended to be used for a short duration and under close supervision. Do not use more than 10 minutes at a time. After 10 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. Please consult your veterinarian about the health of your dog before using this air filter product.

        7. What do vets say about air filter masks for dogs?

        • We are talking to veterinarians about the use of K9 Masks for dogs in poor air quality environments. We are also researching the breathability of dogs wearing the K9 Mask using a pulse oximeter. The pulse oximeter measures the amount of oxygen circulating in the blood. This research will help set guidelines for safely using a K9 Mask. We are also concerned about over heating. Dogs release heat through panting. If anything restricts a dogs ability to pant it can cause overheating in a dog and a potential for heat stroke. 

          8. How long can I use each replaceable filter in the K9 Mask?

          • Effectively using each air filter depends on many factors such as the pollution level, length of use, and moisture level in the mask. 
          • Note: 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.

          9. 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 polluted air. However, the K9 Mask functions to muzzle a dog from barking and biting. During the anxiety of a wildfire, or other extreme weather events, dogs become anxious. A dog wearing the K9 Mask as a muzzle is useful to protect the dog and those around it in these environments.

            10. Does the K9 Mask work when it is wet or raining?

            • We do not recommend using the the K9 Mask in the rain. A wet air filter will restrict a dog's ability to breathe through the air filter. The good news about rain is that it is helpful in cleaning polluted air. Often times rain is able to bond to dust and toxic particles in the air that make air pollution worse. During and after a rain the air quality generally improves. 

            11. How can I share K9 Mask information with other people?

            • Share with people who you believe need to be informed about the need to protect dogs from air pollution. You can advocate for the health of dogs by sharing the good news about the K9 Mask.
