KF94 Disposable Face Mask for Kids, Colored Mask for Boys Girls with Adjustable Ear Loop, Kid Sized Small Mask for School with Moldable Nose Clip, 4-Layers Breathable Children Mask Cover with Custom Size - 20 Packs
I think this is the best face mask for kids. My son have asthma and the other masks we use is moves when he breathe but not this mask. It have enough space for him. The mask does not touch his mouth so he can breathe better.
