I like them

I like that the ties go around my head and not touch my ear at all. Regular masks were hurting my ears. I should've listened to my mom a long time.ago and.gotten masks like these.

surgical masks

I love these masks, They are so comfortable and since I wear a cochlear implant audio processor and a hearing aid the mask does not bother the hearing aids. Before the over the ears masks would make my hearing devices fall off. I am very pleased with my purchase. Jane

I am very happy with these masks. Reason one is because Wirecutter vetted them so I am confident they are protective. Reason two is because I wear hearing aids and behind the ear loops are disastrous for me.

Surgical Mask

Hi, i appreciate the good quality of all my products purchased. The surgical mask is of great quality compared to what I bought early on in this pandemic. The material of the mask is thick, which I like; however I have yet to use them since I was able to purchase the N95 mask from you. I especially like the fact, that you’re on CDC website as a reputable retailer. Keep up the good work and I’ll be back. But, since I have 4 boxes of n95’s and a box of surgical mask it’ll be awhile. And, now they’re lifting the mask mandate smh….i will continue to protect myself and others until this is over, which I doubt, but yo each their own.

Top notch protection - and comfortable to wear - even in sports

I would buy this item again. Why? One, I like double tie rather than behind the ear. I wear glasses, and behind the ear plus glasses is uncomfortable. I appreciate it's ASTM Level 3 - essentially the best protection available short of an N95 respriator. More importantly, it seals nicely over the nose as well as under the chind and around the sides of the face. Best seal I've had of any mask other than an N95. I find it comfortable to. I actually wear this mask during sports competition and have the least problems of any effective mask I've used. Service was good, too. Delivery was prompt.

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).
