The Welkeeps KF94 kids mask passed our particulate filtration efficiency machine test with a score of 99.48%. KF94 masks are boat-style and made in Korea, which has very strict production guidelines. All KF94 masks have ear loops instead of head straps or head ties.
Mask breathability is determined by airflow resistance, which we measure in pascals. The target for adults should be around 150, and the target for children should be close to 100. The airflow resistance of this mask is 134.
This mask has an odor that's slightly sweet (like frosting). The size is likely appropriate for those up to age nine. The nose wire is great, the ear loops are strong and it comes with an optional ear hook to create a tighter fit. Every mask in the pack is decorated with a bear print, too.We found this mask on Amazon. Check out our video review for more details.
