Read below what could cause a light to flash in your Philips Air Purifier.
The filter needs to be replaced or cleaned
When a filter needs to be replaced or cleaned (this depends on the model you own, please check our article about cleaning and replacing the filter) a white light indication will flash in your Philips Purifier.
Once the filter is cleaned or replaced, please reset the filter lifetime counter (as indicated in the user manual). The light indication will then stop flashing.
There is a malfunction
If an error indication (E1, E2, E3 or E4) is flashing, this indicates there is a malfunction in your purifier.
