Techno Mask Replacement Filter (2-Pack)

I ordered this item 4 time the first ordered got what I ordered worked as expectedand. On my second time I ordered this I get a smaller size and for allergy mask replacement not techno replacement. Now on my 3 order I get 1 correct techno mask replacement and 1 allergy mask which is not what ordered. My 4 th order was correct so now have update the star to 3

I use these in China when the air quality crosses a certain threshold. The fit and style are good enough, and it seems to be doing some work. However, after about 5k it gets rather moist inside. After 10k it's almost entirely closed up with moisture. With all the sweat and exhalation, obviously lots of water gets trapped in there & has no place to go. Tough design challenge. Must also take care to dry it well in between uses . . . i lost one mask to mold growth. I still use it, but after about 5k it goes into the pocket.

I haul coal for a living and when I go to unload I tend to end up breathing in a lot of "dust" in the air... this is an issue weather it's coal or dirt, most dust masks suck into your mouth or nose causing it to be difficult to breath...since beginning to wear this filter system I have been able to breath better both as I work and after... and yes heavy use requires Monthly replacement of filters!

Works well,but can get warm in full helmet

Item is exceptional. It's more comfortable and provides an excellent fit to the Respro Masks.

I LOVE THE RESPRO MASK I HAVEBECAUSE IT HAS REPLACEMENT FILTERS!

Arrived promptly. Exactly as described with great discreet packaging. I bought it for my Dad and he hasn’t told me any complaints. Would surely recommend.

good product

Delivery take too long and some weird SMS about import tax payment for $2 dollars

I highly recommend this product,I can't go for a walk with my dog without my mask,to me is a must!!!

Road use. 100 percent need this mask in a city!!!

Filtered face masks for cyclists in London are no longer an optional extra, or simply a protest statement. I cycle daily. Since wearing my Respro mask regularly I feel a lot less tight chested and less prone to sore throats . The mask is as comfortable as a tight fitting filter can be . They make you look like a homicidal robber on a dark night,but the more often they are used the more pedestrians will get used to them.My only grumble is that I need to change the filter at least once a month which makes wearing it daily a significant expense- nearly £15 every two months. But for the sake of my health I think it's worth it.

Great filters for the respro techno masks! The fit is normally a little stiff for a few days but after some use they shape nicely to fit the contours of your face - be warned - it does make you look like you've just woken up with 'pillow' lines around your face.I use the mask for my daily commute on my scooter and I find it indispensable on London roads. I find them comfortable not only to wear but also to breath in - if I were cycling they might get a tad warmer. I change mine when they look visibly discolored so perhaps once every month and a half.They're not cheap but well worth it from a health perspective.
