The card carries these facts from its Wikipedia article.
- Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate.
- Oversize particles may form a filter cake on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter, known as blinding.
- The size of the largest particles that can successfully pass through a filter is called the effective pore size of that filter.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Filtration article was read about 35,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 49: each hit it takes is cut by 20 %.
