Because biofilm clumps sand grains together, it creates \"channels\" that let dirt slip right back into your pool. AFM-ng is 100% bio-resistant, meaning bacteria cannot cling to it. No biofilm = no channeling = consistently perfect filtration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,1,0\"\u003e\u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"0\"\u003eSuperior 1-Micron Filtration:\u003c\/b\u003e While sand filters typically trap particles down to 20 or 30 microns, AFM-ng filters down to an astonishing \u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"138\"\u003e1 micron\u003c\/b\u003e without any coagulants or flocculants.

By preventing bacteria from growing in your tank, AFM-ng slashes trichloramine production by up to 50%, eliminating eye irritation and skin itchiness.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,3,0\"\u003e\u003cb data-path-to-node=\"8,3,0\" data-index-in-node=\"0\"\u003eSaves Water, Energy \u0026amp; Money:\u003c\/b\u003e Because AFM-ng doesn’t get clogged with sticky biofilm, backwashing is much faster and highly efficient.
