The facts on the card
The card carries these facts from its Wikipedia article.
- A HEPA filter is an air filter meeting such a standard.
- A HEPA filter must satisfy certain levels of efficiency.
- Common standards require that a HEPA air filter must remove, from the air that passes through, at least 99.95% or 99.97% of particles whose diameter is equal to 0.3 μm, with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The HEPA article was read about 95,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 73 and blocks with 63: each hit it takes is cut by 25 %.
How to get HEPA
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
