Unfortunately it doesn’t come with a lifetime warranty and instead ops for a 1 year satisfaction guarantee, but customers do get free lifetime support by WQA water specialist based in California. The look of it isn’t as polished and instead they opted for a straightforward, easy to install model with no bells or whistles.

New Wave Enviro 10 Stage Water Filter System

Best Under Sink Water Filter ReviewsIn this interesting low priced product from New Wave, they incorporate a 10 stage water filtration system that gives delicious great tasting water with the ability to remove major contaminants below the EPA minimum levels. What makes this different is that the way it is sold is not to be mounted, but rather sit alongside the faucet area and function alongside it. In order to use it under the sink where it is preferable, buyers will have to purchase a conversion kit that is sold separately. This makes an interesting buying decision for consumers that don’t want to make the extra purchase, or even go through the hassle. For those that want to use it alongside their faucet, it attaches as quickly as any adapter in a few minutes. It rates at about 1,500 gallons per filter, which is awesome to say the least considering its size. And despite that small size it kills potassium, magnesium, chlorides and even fluoride form the water system. A one year warranty is included with a 30 day money back guarantee, so it has some key points to make it stand out from the list if consumers are interested. Worth the look, even if only for the low amount it costs.

This isn’t a game changing feature, but is one of convenience that many will appreciate. This is a WQA certified NSF/ANSI water filtration system that also conveniently comes with a ceramic valve in Euro style brushed nickel faucet that is optional, but so gorgeous that most users will opt to use it. With its easy push button assembly customers won’t have to spend hours reading a manual and trying to figure out how to install the system.

Culligan US-EZ-4 EZ-Change Level-4 Under-Sink Drinking Water System

Best Under Sink Water Filter ReviewsCulligan takes a shot at the water filter market with this low priced option that uses a quick connect fitting to get users started quickly. There is only a 500 gallon capacity per filter, so buyers should expect to change it out twice a year, which is a bit of a letdown when compared to others on the list. The filters do a fantastic job regardless, and makes the water taste better while getting rid of the materials in water that cause it to smell bad. Some of the other materials it rids water of is mercury, turbidity, particulate class 1, chlorine, sediment, cryptosporidium and giardia, VOC’s, MTBE and chloramines. It really gets a lot out of the water and strips it of all of the bad things. So even though the filter lasts only half as long as others, it works twice as hard. As a bonus it has a built in electronic cartridge life indicator so you never have to wonder if it is time to replace it. This is a good option for those that want water filtration, and should serve them well in any size household.

Softener or Under the Sink

The cheaper option is always going to be the under the sink option, mainly because it doesn’t connect directly to the main pipes in the house. So with less configuration there is a lot less moving parts, but it also comes at the cost of not softening the hard water. What under the sink filters do is give you fresh drinking water that is free of several contaminants, which once removed gives you odor free and better tasting water.

Under The Sink Water Filters

Just like a water softener needs a salt change, water filters need to be changed out once their lifespan is gone. They are usually very easy to replace, and in many cases can be twisted off and replaced with a new one within minutes. The aim is for a minimum of 1,000 gallons per filter, but in situations where the water is extra obnoxious in the area a good amount would still be 500 gallons per filter.


There are a lot of under the counter water filter systems to choose from, but that doesn’t mean that they were all created equal. This list shows some of the better ones, and also some of the cheaper good quality ones to choose from. Whatever you decide on from the list, be assured that it will more than meet your water filtration needs.
