Nice size for children

These masks I bought for my two grand daughters ages 4 and 8 to wear when they come inside our home. We are both over 65 and feel we need for them to be masked as well as us when they are around in our home. Although they have not been over since we purchased these masks they are the same quality astm level 3 masks like the ones we buy for ourselves. They are smaller of course and we feel they will fit them well when the need arises for them to wear them here.

I Like These

I like this mask, even though I am not a child. It fits my narrow face, without having a lot of gap on the side. I don't have to adjust the loops.

ONGO Returns Policy

Due to health and safety concerns, COVID-19 Antigen Self-Tests cannot be returned even if unopened and no refunds will be issued. Accordingly, all sales of COVID-19 tests are final.

PLEASE NOTE EXPIRATION DATES BEFORE PURCHASING. Currently, the test expires on the last date of the month printed on your box (i.e. January 2022 means January 31, 2022). However, with medical products under EUA, such as On/Go, the FDA, after close studies, grants rolling expiration extensions. We expect the expiration date to be extended before the end of January and another expiration extension again early in spring. We will continue to closely update our website when the expiration date gets extended.

DemeTECH reserves the right to remedy customer issues and concerns on a case by case basis based on the facts and circumstances of each customer.
