The Crayola face masks have adjustable straps and wire nose pieces. They're small and fit my 3 year old well, but she also likes wearing her brother's masks, which are a bit bigger. His masks have the same features, but are made by Simple Modern. Both purchased on Amazon.

KF94 kids masks.

My tiny 1st grade nephew wears the Vistaprint masks. They’re protective enough to satisfy my nervous and picky sister.

GAP pleated masks...they have a nose wire.

I would try to find kids KF94 masks with adjustable ear loops to fit them closer to smaller faces.

These old navy ones have ear adjuster and nose wire and are 3 layers. My four year old wears these daily

These masks fit my 4 and 6 year olds perfectly. I don't see the kid-sized masks listed on the website, so you might have to call and ask... although, it looks like the prices are insane! (I had no idea, my MIL sent us a haul of them). I can, however, speak to the quality...they are great.

my teens like these masks. there's a gap of space in front of their mouth so the fabric doesn't feel sucked in when they talk; and they are very light:

The Carter's pleated masks fit my 4 year old great - but if you want something with a nose wire, Construct on Amazon are small (too small for my 7 year old, but fit my 4 year old great) and fit tightly. My 4 year old will only wear pleated masks, they are the only ones that don't slip.

My 4yo and 6yo are most confortable in the vistaprint masks. The for well with no gaps. Lightweight but you can add a filter. Nose wire and adjustable straps. They also sell an extension that wraps around the head I think. We also have Vogmasks but they are thicker and the straps are a bit too thick for small ears.

I’m going to disagree with the last poster. We’ve bought so many masks for our kid and the ones that fit best are the pleated kid’s masks from Old Navy. I think it just depends on your kids face. We’ve found that for him to wear a mask for hours, the nose wire doesn’t matter but it has to fit perfectly over his ears, and the ON masks have easily adjustable ear straps. You might have to try several styles before finding the right ones fir you.

Link to brands?

Nose pinchers and adjustable straps are essential for a good fit for long periods of time. Get lots. My 4 year old has 3 sent to school daily as they get wet. We do a big mask wash on the weekend.

We’ve been using old navy masks but we want other more protective options since our kid is heading to in person prek. What brands do you love?
