Lalolagi leaga filtration o se ki gaioiga laʻasaga i le faʻatuatuaina ma faifai pea gaosiga o fualaʻau suauʻu, suauʻu 'aina, ma isi meaʻai meaʻai.

Lalolagi leagafesoasoani faamama e mama i le mamafa, chemically inert, ma fausia maualuga porosity faamama keke e tausia saoloto-tafe o le suavai. Faʻapitoa lava, o se lelei fesoasoani fesoasoani e faʻaalia i mea nei:

O le faʻavaeina o fasimea e tatau ona faʻapea o le a latou le tuʻu faʻatasia vavalalata, ae o le a fausia ai keke e 85% i le 95% pore avanoa. E le gata i le faʻatagaina o le maualuga o le tafe o fua, ae o loʻo iai foʻi avanoa e puʻea ma faʻapipiʻi ai mea mautu aʻo tuʻuina le maualuga pasene o auala e tafe.
