Just get an extra spare Air Dryer king on stand-by in case you need to recharge the one running with your Ozone King set.

Just replace the Airdryer King when needed and bead can be recharged at a later point of time.

In order to function properly Ozonizers need dry air. The humidity is too high in Singapore so we need a reliable source to provide dry air, such as the Air Dryer King.

The beads of the Air Dryer King have a color identification. When read to use they are orange. When exhausted they look green/brown.

Just remove the beads, put them in an ovenor 20-30 minutes at about 110 degrees and they will be recharged.

The 4mm standard air hoses can be used.
