Dear John,
This is Gustavo from Vogmask Taiwan. We respect your opinion on choosing Respro over Vogmask. Nonetheless, I want to add some relevant and updated information:
Vogmask products are now officially available in Taiwan through us, Vogmask Taiwan. Your masks will often arrive next day after your order, and there is no need to deal with Taiwan Customs anymore.
Respro masks need their filter replaced after every month, with filters being $22 for a pack of 2. Vogmask can be used for about 5 months at no extra cost. This is something to take into account when considering total cost of ownership.
Regarding your comments on comfort, we acknowledge the 3 sizes we offer will not fit every possible person out there. With a properly fitting Vogmask there should not be any ear pulling, nor any air escaping from the top of the mask or fogging issues while wearing glasses. From your comments I can imagine your L sized Vogmask is simply not big enough for you. We are aware of this, and an XL sized mask is in the pipeline.
We also offer an adjustable head strap accessory for those who are not comfortable supporting the mask on their ears or who want a tighter, adjustable fit.
About the ear loops, note that when the mask is new they can feel too tight, but will naturally stretch over the first few weeks of use. This can be helped with some gentle manual stretching out of the box.
