All of our Respro masks come with a combination filter would be suitable for environments where pollution is high and full of exhaust gases and various particulates including PM10, PM2.5 and respirables (sub-micron).

Do the filters need replacing, if so, how often?

Yes, the filters do need replacing. The effective working life of Respro® 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 or every 69 hours, whichever is sooner.

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. Although spare valves and filters are available from your retailer, please be careful not to misplace any of the components during maintenance.
