Jej\u00ed princip byl pro svou jednoduchost pou\u017e\u00edv\u00e1n ji\u017e ve starov\u011bku.   V\u0161ichni v\u00edme, \u017ee mokr\u00fd p\u00edsek se slep\u00ed v tuhou, hmotu. Tou neprojde tak\u0159ka nic, krom\u011b vody. Ve\u0161ker\u00e9 tuh\u00e9 \u010d\u00e1stice, je jedno jak velk\u00e9, jsou zachyceny mezi jednotliv\u00fdmi zrn\u00ed\u010dky. A to plat\u00ed i pro \u010d\u00e1stice \u0159as a sinic, kter\u00e9 pat\u0159\u00ed k nejv\u011bt\u0161\u00edm nep\u0159\u00e1tel\u016fm nejen zahradn\u00edch, ale i p\u0159\u00edrodn\u00edch koupali\u0161\u0165.   A v tom je pr\u00e1v\u011b cel\u00e1 jednoduch\u00e1 kr\u00e1sa. Voda se \u010derpadlem vh\u00e1n\u00ed do filtra\u010dn\u00edho za\u0159\u00edzen\u00ed. Zde mus\u00ed proj\u00edt p\u0159es masu mokr\u00e9ho p\u00edsku, aby nakonec vy\u0161la ve spodn\u00ed \u010d\u00e1sti \u010dist\u00e1, zat\u00edmco ve\u0161ker\u00e1 \u0161p\u00edna se zachytila ve filtru. Je zaj\u00edmav\u00e9, \u017ee tento princip n\u011bkdy pou\u017e\u00edvali i trose\u010dn\u00edci na opu\u0161t\u011bn\u00fdch ostrovech, kdy\u017e si nebyli jisti, zda je voda opravdu pitn\u00e1. P\u0159efiltrovali i p\u0159es p\u00edsek a v\u011bd\u011bli, \u017ee je bezpe\u010dn\u00e1.  V ka\u017ed\u00e9m p\u0159\u00edpad\u011b se objevuje ot\u00e1zka, jak zamez\u00edme tomu, aby n\u00e1m \u010d\u00e1ste\u010dky p\u00edsku neodt\u00e9kaly do baz\u00e9nu. A zde pr\u00e1v\u011b p\u0159ich\u00e1z\u00ed ke slovu v\u00fdb\u011br materi\u00e1lu. M\u00e1me p\u00edsek r\u016fzn\u00e9 hrubosti, s r\u016fzn\u011b velk\u00fdmi zrny. Jak ale zjistit, kter\u00fd z nich pou\u017e\u00edt? Pokud by \u0161lo \u010dist\u011b o odstra\u0148ov\u00e1n\u00ed ne\u010distot, potom plat\u00ed, \u017ee \u010d\u00edm jemn\u011bj\u0161\u00ed materi\u00e1l, t\u00edm l\u00e9pe. \u010c\u00edm jsou toti\u017e jednotliv\u00e1 zrn\u00ed\u010dka men\u0161\u00ed, t\u00edm v\u011bt\u0161\u00ed nab\u00edz\u00ed celkov\u00fd prostor k tomu, aby se na nich ne\u010distoty zachytily. Nav\u00edc mezery mezi nimi jsou men\u0161\u00ed, co\u017e znamen\u00e1, \u017ee odfiltruj\u00ed i mnohem men\u0161\u00ed \u010d\u00e1stice. Probl\u00e9m v\u0161ak le\u017e\u00ed v tom, \u017ee pr\u00e1v\u011b takto jemn\u00fd p\u00edsek nedr\u017e\u00ed p\u0159\u00edli\u0161 tvar a je velk\u00e1 \u0161ance, \u017ee se z n\u011bj \u010d\u00e1st vyplav\u00ed do baz\u00e9nu. Na druhou stranu, pokud vezmeme p\u0159\u00edli\u0161 hrub\u00fd, pak ur\u010dit\u00e9 typy zne\u010di\u0161t\u011bn\u00ed propust\u00ed. Je tedy t\u0159eba hledat kompromis. Prvn\u00edm a nejd\u016fle\u017eit\u011bj\u0161\u00edm po\u017eadavkem je to, aby za mokra vytv\u00e1\u0159el kompaktn\u00ed hmotu, ze kter\u00e9 se ani v siln\u011bj\u0161\u00edm proudu neodd\u011bluj\u00ed \u010d\u00e1sti. Tento po\u017eadavek nejl\u00e9pe spl\u0148uje k\u0159emi\u010dit\u00fd p\u00edsek s malou p\u0159\u00edm\u011bs\u00ed kam\u00ednk\u016f. A je to pr\u00e1v\u011b on, kter\u00fd se nej\u010dast\u011bji pro tyto \u00fa\u010dely vyu\u017e\u00edv\u00e1. Na\u0161t\u011bst\u00ed se z\u00e1rove\u0148 jedn\u00e1 o pom\u011brn\u011b b\u011b\u017en\u00fd druh, i kdy\u017e m\u016f\u017ee b\u00fdt trochu n\u00e1ro\u010dn\u00e9 naj\u00edt n\u011bjak\u00fd dostate\u010dn\u011b \u010dist\u00fd. Na\u0161t\u011bst\u00ed to znamen\u00e1, \u017ee ho lze sehnat za p\u0159ijatelnou cenu. Nen\u00ed tedy d\u016fvod, pro\u010d byste ve sv\u00e9 filtraci nem\u011bli m\u00edt to nejlep\u0161\u00ed.
