I don't know if these filters for permanent installation have some techology to prevent this, but the smaller jug-style water filters increase bacteria growth if you don't regularly exchange them. I think for a part with such a huge internal surface that is permanently wet, this is really hard to avoid unless it has a special desinfection mechanism.

For short-term use while hiking I use water filters by Sawyer or Katadyn so far without problems. But I rinse them with chlorine and vinegar before I put them away for storage.

I know somebody with a full house filter, and it uses UV to reduce bacterial growth.

That study was done in 1996 and afaik the only way to actually read it is to pay $35. But, judging by the short tldr that's not always the case. About 1/3 of the time that's not the case, and without having the details IDK if this info is useful? Like did 2/3 of the times where the filters just not cleaned properly or at all? Who knows?

"The microbiological quality of filtered water in a commercial water filter system (Brita) was tested in households and in two laboratories. In 24 of 34 filters used in households, bacterial counts increased in the filtered water up to 6,000 cfu/ml. In 4 of 6 filters tested in the laboratory, bacterial counts in the fresh filtrate were higher than in tap water after approximately one week of use both at room temperature and at 4 degrees C, suggesting growth or biofilm formation in the filter material. In some cases colony counts in the filtered water were 10,000 times those in tap water. The filter material of 5 of 13 new commercial filters was contaminated with bacteria or moulds. National or international regulatory agencies should ensure that water filters marketed for domestic use do not allow deterioration in the microbiological quality of drinking water."
