For a 100cm x 100cm input hole, you'll want something sturdy and efficient. I'd go for a HEPA filter if you're dealing with air quality concerns, especially if it's for something like a ventilation system.
After I looked at the prices, I have no desire to use these filters for ASICs, because they are very expensive. Well, why pay 20-30 dollars for 1 filter? ASICs do not need such air purification, and simpler and cheaper solutions are usually used. Such a filter is probably only for exceptional cases, but even then I would use 2 filters. One is for rough cleaning of dust and dirt, and the second is regular.
