Re-Mask Shield Filter package includes 4 filters. Each can last 90 hours, or if it's difficult to count, we usually recommend to change within 1 week under normal outdoor wearing. Please choose the right size for your RE-MASK.
IMPORTANT: Please note that we only sell Filter to our existing customer, or customer who purchase WITH a mask. If you order it by mistake, we will refund to you.
