What do the timer and auto blinking lights mean on the HSP002 purifier mean and how can I reset these?

The blinking means it's time to replace your filters! 

For the best performance and longest lifespan, use a certified HSP002 Replacement Filter (H13 True HEPA).  You can set up a Filter Club subscription to get these delivered every 4 months or do a one-time purchase. 

To change your filters complete the following steps: 

1. Hold down the timer+auto buttons for 3 seconds. When these stop flashing this means the buttons have been reset.  
2. Turn off the purifier. 
3. Remove the front panel, pre-filter, and the old filter. 
4. Install the new filter, the pre-filter, and the front panel. 
5. Turn on the purifier and enjoy fresh clean air!
