1. Do the filters need replacing, if so, how often?
Yes, the filters do need replacing.
The effective working life of Breathe Masks® filters depends on a number of factors, such as; the breathing rate of the user; ambient levels of pollution; the length of time the filter is actively working; hygiene levels. Taking these factors into account we recommend that the filter should be replaced every month.
2. Do I need to replace the valves?
The valves should not need replacing on a regular basis assuming that they are maintained properly. On a monthly basis, it is advisable to flush the valves through with warm water, allow to dry and apply a little talcum powder to prevent the valve from sticking.
3. Can the mask be washed?
It is recommended that you wash the neoprene shell of the mask every month under normal use. To do this it is necessary to remove the filter and the valve first.
4. These bendy nose things, how far should I bend them?
The malleable nose clip deforms easily so that a good fit can be formed around the bridge of the nose. Continuous or exaggerated deformation will eventually cause failure in the metal - it will snap. Once a good fit has been found, it is best to maintain the shape, rather than folding it flat when storing it or when not in use.
5. Why are my glasses misting up, and How to prevent misting of glasses?
A good seal around the nose and cheekbone will result in a correct fit and prevent misting. Having adjustable nose pads facilitates a better fit than plastic moulded rims.
6. Is it normal to feel like my breathing is restricted?
Every mask will have some level of restriction, more so at fast breathing rates, example: when cycling fast. All of our pollution masks are compatible with aerobic exercise. If the body starts working in an anaerobic capacity then no mask is compatible and you will feel like you need to stop or slow down.
