What to know about maintaining your Ozone Module for reliable long-term performance.
Particulate Filter Check and Replacement
The Clarity Ozone Module was designed for low maintenance operation in the field. The only check the customer will need to schedule is to inspect and replace the particulate filter if needed.
The particulate filter blocks particles from contaminating the flow path. Depending on the particular matter concentrations in the ambient air, the filter may saturate and will need to be replaced periodically. Assuming a high average particulate matter ambient concentration (~50 μg/m3), the estimated filter lifetime is shown as a function of the sleep time (sec) of the Clarity Node-S in Table 1.

Because the actual particulate concentration will vary by site, we recommend checking the filter after 2 months of ozone module operation and replacing the filter.
Particulate filter replacement can be performed by the customer. A video on how to replace the particulate filter can be found below:
To ensure the filter was replaced properly, a zero check should also be performed afterwards. A video on how to perform a zero check is forthcoming!
Ten (10) new particulate filters are included in the box with every ozone module. If more filters are needed they can be ordered directly from Savillex as part #450-57-4
Recalibration of the Ozone Module
We also recommend a recalibration every two years, which requires sending the unit back to be completed. To start this process, please contact us at support@clarity.io.
