This is one of the higher quality NeoVision masks.
The filter offered on this mask is the highest quality on offer and similar to the ACF but without the one-way valve but with this mask we offer replacement filter so that the mask can be continuously used.
The mask has a Velcro strap which fastens behind your head for extra comfort.
This mask is highly recommended for travelers or expats looking for a mask to use for a long time.
Can be used up to 6 months before the filter should be replaced.
