Before you purchase a water filter, go to www.ewg.org/tapwater and look up what contaminants that are in your water system. Please note: a whole house filter does NOT provide the same level of filtration that a drinking water filter does. You still need a drinking water filtration system in your kitchen, even if you have a whole house filter. I do not recommend Reverse Osmosis Filters unless it has a remineralizing stage on it.

In my opinion, this is the best undersink water filter system available. It removes up to 99% of all contaminants, including fluoride, PFAS, Heavy Metals, Radioactive contamination and everything else you might be concerned with, but has all the minerals intact for a full electrolyte, delicious, clean water. This is the only filter that I have found that certifies it removes not just microplastics, while preserving minerals.
If you aren't able to install an undersink or it's out of price range for you, Clearly Filtered also has an inline behind the fridge filter ($165) that will provide your fridge water & ice with pure, clean water.
If for some reason you aren't able to install a water filter underneath your kitchen sink and a behind the fridge option like Clearly Filtered isn't something you want, then the Rorra Countertop Filter is your best option. This filter will remove everything you want out, except for fluoride.
This is the best on the market, IMO. Pure Effect is my favorite water filter company in general. Highest quality, uses compressed catalytic carbon, vice granular, easy to change cartridges, no fouling, no backwash and very little maintenance and leaves minerals intact.
** Make sure to flush your system and turn it off once a month. Read the user manual.
The biggest complaint surrounding shower filters is that it really reduces water pressure, especially if it's a filter that does any real reduction in contaminants. Eskiin is newer to the market and is hands down the best combination of chlorine removal, contaminant removal and water softening. It uses a blend of KDF-55 and calcium sulfite with coconut activated carbon. If you want the BEST contaminant removal, you'll have to sacrifice the softening. See those options below.
