It really depends on your water. Most filtration systems excel at different levels for varying factors. Some target minerals more than microbes and some are more for sanitizing. it depends on what your needs are. Every manufacturer will tell you theirs is the best but is it the best for you? There are some over the counter test kits to check for flouride, chlorine, minerals, etc. or you can take a sample to a lab and have it analized. Your water supply should be able to point you towards a few companies or provide the same data on the water they are supplying. Armed with that knowledge you can select a purification system that meets your needs without buying something you don't need. Once you figure out what type of system you need read reviews of those systems online to find one that seems reliable and does the job.

Your question has two parts: 1) what is a good reverse osmosis filter, and 2) what is a good filter for a refridgerator?

I can recommend the Whirlpool WHER25 reverse osmosis filter system from Lowes (see website URL below). I have installed two of them (including one in my own home) and have had no problems or issues with either one. Of course, you do need to change the filters from time to time, but that is the nature of the product. This system is slightly more complex than a standard filter to install (takes about an hour), but does produce excellent quality water.

We have a $35 in-line charcoal water filter for the refrigerator, which works well. Many high end refrigerators now have built-in filters, so be sure to check yours to see if it does. It is usually simple to remove (one twist) and replace.
