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