Does your filter need changing? The effective working life of Respro® filters depends on a number of factors: 1. The activity rate of the user 2. The levels of pollution or particulate matter in the air 3. The length of time the filter is actively working or being used As a guideline, we recommend that the filter should be replaced every month. Filter multipacks are a great way to save time and money.
