フィルター is used in the same way as "filter" in English. You can use it when talking about filters in cameras, filters in water purifiers, or even metaphorical filters like those used to screen information. The context will usually make it clear what kind of filter is being referred to. You can say フィルターにかける, which means "to put something through a filter" or "to filter something".

フィルター is written in katakana, フフィルター, because it is a loanword from English. There are no other ways to write it, and no variations in the okurigana.

There aren't many direct synonyms for フィルター in Japanese, as it is a specific term. However, depending on the context, you might use: ⚫︎ ろ過（ろか） (roka) - filtration, filtering (mainly for liquids) ⚫︎ 選別（せんべつ） (senbetsu) - selection, screening (e.g., sorting information)

There is no direct antonym to this word. The idea of not filtering, or allowing everything to pass through, would be the opposite concept, but it doesn't have a single word equivalent.
