💎 PORE SIZE of 0.2 to 0.5 micron (human hair is 40 to 300 microns) In other words, the stated pore size of filter isn’t literally the size of the pores. It’s a rating of what can’t pass through them.

💎 LIFE OF FILTER is 1000 gallons or 1 year whichever comes first.

Scrubbing the surface of the ceramic dome with a scouring pad or soft brush under cool running water will unclog the pores on ceramic and expose a new layer for use
