You cannot determine the quality a water filter by its price. An expensive water filter may not perform better than a less expensive one. You don't have to spend $5000 or more for a water filter if your drinking water problems are just taste and odor.
If your water smell or taste bad and if you have tested it for the exact problem, you can find an effective filter for just between $90 and $200. There are countertop and undersink water filters good enough to remove taste and odor and other harmful chemicals from your water. If you prefer to treat the water in your whole house, you can also find a less expensive filter for just under $1000.

Bottled water may contain chlorine, according to EPA. Chlorination is one of the methods being used to disinfect most bottled water. You can get the same or better quality water when you bottle your own tap or filtered water.
If you want to remove chlorine from your shower and drinking water, you can buy a good showerhead filter and a countertop or an undersink filter for drinking. Chlorine in shower water is known to cause flaky skin.
If you do prefere to treat the entire water entering the whole house, water filter options include but not limited to activated carbon, reverse osmosis and distillation.
You need to understand that EPA does not approve water filters. According to information on EPA's website, it only “requires registration of home water treatment unit filters that incorporate a disinfectant to inhibit microbial growth” such as water purifiers.
Don't fall for advertising deceptions that a certain water filter is approved by EPA. National Sanitation Foundation (NSF) International and other independent organizations will certify home water treatment units.
NSF performs rigorous testing on the treatment units and filter media to make sure they perform according to manufacturers’ claim. They make unannounced visits to water filter companies every year to make sure the claims are still true.
Water filters may be certified for one or multiple water contaminants. If you are concerned with taste and odor, metals, nutrients, fluoride, lead, or sediment in your water, you can always find an NSF-certified water filter system that meets your need. Some are labeled as NSF/ANSI or UL certified. Read the water filter descriptions for information; but most often you will see a bold NSF logo on the box.
