A very decent, well made and with good qualities the Culligan US-EZ-4 EZ water filtration system will deliver healthy, tasty water right to your sink.

It is certified by NSF International to NSF/ANSI Standard 42 for the aesthetic reduction of Chlorine Taste and Odor, Chloramines and a number of other certification standards for water treatment systems. The product fits conveniently under the standard kitchen sinks and comes with a dedicated faucet.

Being a low-cost water filtration system that does its job well, it will not only save you money upon purchase but in the long run too. The product is fairly easy to install and super easy to maintain. Comes with all parts needed for the installation.

Performance

Culligan US-EZ-4 EZ-Change Undersink Drinking Water Filtration SystemThe Culligan US-EZ-4 EZ comes with a premium 500-gallon filter. This filter reduces particulates class I, chlorine, cysts and chloramine, MTBE and Mercury, lead, turbidity, perfluorinated chemicals (PFOA & PFOS). Though the system is inexpensive and not a 3-stage one, as are other under sink filtration systems on the market, it is still a very effective gadget for any household.

The US-EZ-4 filter can remove up to 97% of the chlorine at it will be visible – the white flakes in your boil water should disappear. Needless to say, your water will definitely taste much better and will have no odor.

What is great for this product is that you get to choose which filters to install. If you have higher filtration needs you can just upgrade to another cartridge. There are RC-EZ-1, RC-EZ-3 and RC-EZ-4 filters, all interchangeable so you can find the one that suits you best.

Another convenient feature is the LED built-in filter life indicator that will inform you when it’s time to change your filter.

The water yield of the system is 0.5 GPM at 60 PSI. The lifetime of the different filters and this particular one is 6 months or 500 gallons. Except for the US-EZ-1 that has a lifetime of 12 months, but doesn’t remove heavy metals and chloramine taste and odor.

Features

The US-EZ-4 set includes a filter head with a built-in bracket, the cartridge, mounting screws and water supply adapter. It comes with chrome, lead-free faucet and fittings. There is also a faucet battery available for the US-EZ-3 and 4 models. The tubing is 1/4″ and it is plastic. A cartridge change reminder sticker is also included.

Installation and maintenance

The installation of this product shouldn’t take more than 40 minutes if you prepare well. As it comes with 1/2″ tubes to connect to water hoses, and your house may have the 3/8″ supply lines, you will need a compression saddle valve with a 1/4″ hose hookup. Another solution could be a T-connector that adds another line and includes a male and a female 3/8″ connector and a 1/4″ outlook to hook your Culligan system. This is really a minor issue considering the product’s qualities.

To avoid any leaks be sure not to tighten the connections. They are plastic and are pretty adequate for a domestic water pressure. If you are willing to have metal parts, you should consider another product. Also, be sure to properly cut the hose that comes with the unit.

Just take your time and read the instructions before you begin. Also, check your piping to see if and what additional parts you might need. If it’s your first plumbing experience, you might also want to look for professional help.

When it comes to maintenance, these filters are super easy to change. With only a twist on and twist off mechanism, you are spared from using buckets, towels, wrenches, and other tools.

Pros:

  • Low cost and high-quality performance
  • Certified with NSF standards
  • Possibility to upgrade filters depending on your filtration needs
  • Easy to install and maintain

Cons:

  • Might need additional parts
