WNL 5000ITM Practi-Mask Infant CPR Training Mask Includes 10 Masks 5 Practi-Valve Plus Reusable CPR Training Valves and 5 Replacement Filters

Great for training! I toss them in the washer with whites and towels on the super hot "whitest white" setting after each class!

I've been trying to get my cat to use an inhaler for many months. He hates having the mask placed over his nose, however. I've tried other spacers to see if he preferred them but these masks were the only compromise he would tolerate. They do fit nicely over his nose and the stem fits perfectly into the Aerokat spacer. Hope this helps other cat owners or those with small dogs. It's an option. Highly recommended!

These training mask seem to lose their air. They don’t last very long, not many uses out of them. I don’t know if it’s a bad batch or a bad product.
