First off I would always rinse any filter paper with 200-300ml of water as a minimum.
I have always found the unbleached filter papers to have an unpleasant taste and smell - like wet cardboard. In particular the Chemex unbleached get a bad press although I have not found them better or worse than most other unbleached. Try pouring boiling water through bleached and unbleached papers and have a look/smell at the filtered water. Taste if you dare.
I would always go for bleached white filter papers with Filtropa being a preference. The brown "natural" filter papers sell as being more "natural", "less treated" etc. but frankly the bleaching process improves there functionality.
The bleaching process is an oxygen based process, as I understand it. I have never identified a "bleachy" taste specifically from white filter papers, in that these papers are not bleached using chlorine based bleaches eg Chlorox, Domestos that you would use in the home and be familiar with.
No filter paper is going to be entirely neutral, especially when brewing small quantities, but on balance the white bleached papers seem to have less of an effect than the brown ones. If you try the comparison between bleached and unbleached types of filter using plain boiled water, as I mention above, you will surely form your own conclusions.

My Chemex experience is reverse; I hate the brown ones because they taste like a paper grocery bag, but the white ones are fine (after rinsing with a good 250mL of water). Melitta browns do fine after rinsing, but I prefer the bamboo melittas.

FWIW, I have never found a brown filter paper -- regardless of brand -- to be as good as the WHITE filter paper of the same brand, after rinsing in hot water. Chemex, Melita, Filtropa, and others: every WHITE paper yielded noticeably better coffee in the cup than its brown counterpart, all else being equal. This has been echoed by people I've spoken with in coffee bars/cafés and in stores.

I've tried Filtropa White vs Melitta Bamboo in a Hario 02 dripper. So far I like Filtropa better. I grind on the fine side and I've noticed fines in the cup with Melittas. Granted I have not used them too many times, this could have been an aberration. Both have a smell when rinsing, the Filtropa smells bleachy. The Melitta has a strange smell, I guess it's bamboo, not really sure. Where do you guys find Filtropa whites besides SM? Williams used to have them but their site says no longer available.
