ResproTechno Mask Replacement Filter (2-Pack)

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!

After wearing my mask for a few hours every day for a day or two, the bridge of my nose started to get red and increasingly irritated from the stitching around the edge of the filter. I wish they used a softer thread material!

I ordered this item 3 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.

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.

Havent used it yet but the mask is awesome

Works well,but can get warm in full helmet

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.

Use it every day riding my bike in the city. Its a big difference. Factory recommends change it every month.

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.

Lov these but with what is happening they are really hard to get hold of.

Perfect

Son buenos filtros pero demasiado duros en mi opinión. Con duro me refiero a que cuesta algo respirar cuando estas subiendo una cuesta y a veces me lo tengo que quitar. Por lo demás, altamente recomendable. Duran mucho y son imprescindibles si pillas la bici en ciudad.

Ojo son los repuestos y no la mascarilla. Filtran el aire de la ciudad, son un poco duros, cuesta un poco respirar en las subidas. Son ideales si hace frío, Me parecen un poco caros. Llegó en los días prometidos.
