When should I change the filter in my ProBreeze PB-P01 5-in-1 Air Purifier for optimal performance?

[LaAngelina]

To keep your ProBreeze PB-P01 5-in-1 Air Purifier running efficiently, you should clean the filter monthly using a vacuum cleaner and replace it annually or after 5000 hours of use, as stated in the manual. The air purifier has a built-in indicator. The sleep button on the unit will flash continuously after 5000 hours of use, signaling that it's time for a replacement. After replacing the filter, reset the timer by pressing and holding the sleep button for 5 seconds. To replace the filter: First, switch off and unplug the air purifier. Then, remove the front panel by lifting it. Next, pull the two tabs at the top of the composite filter to remove it. Install the new filter with the blue side and pulling tabs facing outwards. Finally, reattach the front panel. The replacement filter model for your ProBreeze PB-P01 is PB-P01 F.
