Why did the checkout page say my zip/postal code is incorrect?
For the safety and security of all customers’ financial information, our systems verify the billing zip/postal code of credit/debit cards with the card issuer. If you see “your billing zip code is incorrect” at checkout, your bank or credit card company’s systems have indicated that what you entered does not match what they have on file. Please contact them to verify your billing address, then feel free to return to checkout.

What is nanofiber, and how many times can the masks be safely washed?
Nanofiber is a filter with a structure in which long and thin fibers superimpose with a thickness of 200 to 500 nano-filters. It physically locks small particles, and it is easy to wash out particles caught by the filter with water.
The filter is deformed very slightly when washed several times, and the particle filtration rate drops to about 50% after washing 20 times. Given this, We recommend a maximum of 20 washes.
How do I wash my mask?
Please wash your mask by hand using warm water and mild, liquid dish soap. Then, allow to air dry. Do not machine wash or dry.
My stopper came off, how can I thread it back on my mask?
We have created a video demonstrating how to thread a stopper back on your mask strap. Please visit our About the Mask page to watch it.
