At my home, I use a filtering faucet with a carbon filter (the same thing you see in those filtering pitchers, or some fish tank filters). Mid-tier refrigerators that produce chilled tap water frequently include this kind of filter. I installed an ultraviolet sterilizer before the filter. This has no effect on the taste, but it does prevent most sorts of pathogen from colonizing the filter. This isn't generally an issue, but we felt like it made sense to add this when we installed the filter anyway. At my office (same municipal water source), we have a very fancy reverse-osmosis filter. This is the same thing most of the bottled water companies use. I slightly prefer the taste of this water, but I think this is just because it's colder. The device is much more expensive initially ($200+, vs. $10 for one of the pitchers or around $50 for an under-sink carbon filter).
