The RAMA Lite 4" Spirit Candles have a lifespan of up to 3 months or approximately 3,000 liters per pair, depending on water quality and usage. Monitoring the flow rate and clarity of the filtered water is recommended to maintain optimal performance.

No. Priming is not required for the Lite 4" Spirit Candles. Simply rinse them thoroughly under running water before installation and discard the first two batches of filtered water. After that, they are ready for regular use.

The Lite 4" Spirit Candle provides effective two-stage purification and removes:

• Suspended particles & turbidity
  Dust, dirt, rust, silt, and other visible impurities are captured by the fine ceramic layer.
  
• Chlorine & chemical residues
  The activated component helps reduce chlorine, VOCs, and chemical contaminants that affect taste and smell.
  
• Bad taste & odor
  Improves the overall taste and removes unpleasant smells.
  
• Microbial contaminants
  The ceramic microfilter reduces bacteria and cysts down to 0.5 microns, while the sterilizing layer helps inhibit mold and bacterial growth.

Together, these stages deliver clear, clean, and safe drinking water suitable for everyday use.
