Kube Water Filter Advanced Water Filtration System Review

Last Updated on December 29, 2023 by Richard

A great choice for apartments or anyone on the move. The Kube water filter is extremely simple to install on the cold water line. See the video below.

It could also be connected to a second faucet and the refrigerator.

Filter changes are even simpler and the filters last about six months to one year. Depending upon family size and incoming water quality.

At least two customers prefer the Kube water filter over any reverse osmosis system. They like the taste, low maintenance, and lower overall cost to make great water.

Customers also like that the Kube doesn’t take up much space like other systems do. It’s just 6.2 inches wide, 18.5 long, and 13.1 inches tall.

How Pure Is The Water From The Kube Water Filter?

The Kube water filter system was tested and certified by the WQA (Water Quality Association) and passed the standards for the NSF/ANSI 42 and 53 requirements.

Below is the Kube performance data sheet from the NSF organization.

I also went to the WQA website and found that the Kube water filter passed the NSF/ANSI 42 and 53 standards. Here is the list of pollutants that those NSF tests ensure that the Kube water filter removes below EPA safety levels:

  • Aesthetic Chlorine
  • Nominal Particulate Class I
  • Taste and Odor
  • Cysts
  • Lead
  • Mercury
  • Methyl Tert-Butyl Ether (MTBE)
  • VOC (as chloroform)
  • pentachlorophenol
  • simazine
  • styrene
  • 1,1,2,2-tetrachloroethane
  • tetrachloroethylene
  • toluene
  • trichloroethylene
  • trihalomethanes
  • chloroform
  • bromoform
  • bromodichloromethane
  • chlorodibromomethane
  • xylenes
  • alachlor
  • atrazine
  • benzene
  • carbofuran
  • carbon tetrachloride
  • chlorobenzene
  • chloropicrin
  • dinoseb
  • endrin
  • ethylbenzene
  • ethylene dibromide (EDB)
  • haloacetonitriles (HAN)
  • bromochloroacetonitrile
  • dibromoacetonitrile
  • dichloroacetonitrile
  • trichloroacetonitrilehaloketones (HK)
  • 2,4,5-TP (silvex)
  • tribromoacetic acid
  • 1,2,4-trichlorobenzene
  • 1,1,1-trichloroethane
  • 1,1,2-trichloroethane
  • 2,4-D
  • dibromochloroproane (DBCP)
  • o-dichlorobenzene
  • p-dichlorobenzene
  • 1,2-dichloroethane
  • 1,1-dichloroethylene
  • cis-1,2-dichloroethylene
  • trans-1,2-dichloroethylene
  • 1,2-dichloropropane
  • cis-1,3-dichloropropylene
  • 1,1-dichloro-2-propanone
  • 1,1,1-trichloro-2-propanone
  • heptachlor (H-34, Heptox)
  • heptachlor epoxide
  • hexachlorobutadiene
  • hexachlorocyclopentadiene
  • lindane
  • methoxychlor

That’s a mouthful you don’t want to swallow.

Got Hard Water? The Kube Water Filter Will Help

Although it isn’t designed to remove hard water some of the customers say it really makes a difference in their water quality. If you have really hard water, you will need a water softener before using the Kube water filter.

Which brings us to Total Dissolved Solids (TDS).

Many people mistakenly think that any amount of TDS means that the filter isn’t working properly. That couldn’t be further from the truth.

TDS includes pollutants you don’t want and the magnesium and calcium minerals you do want. The Kube doesn’t remove those good minerals.

However, since the Kube does remove the toxic dissolved solids, the water harness is reduced somewhat.

Does The Kube Decrese Water Pressure?

That’s to be expected to some degree. It is more noticeable when your water pressure is already low. Whereas, if you have high water pressure, you may not notice any decreased water flow.

Several customers didn’t see much difference in water pressure, but one customer did.

How Easy Is The Installation Really?

The Kube water filter system comes with everything you need for installation. Including the two filters, hoses and pipe fittings.

One customer said he was done in ten minutes, and two other customers said less than 30 minutes.

The video tells you to cut the hoses short, but it might be a good idea to leave them long. That way if you ever have to clean around it or behind it, you can easily move it around.

Also, the serial number and other information you might need is located on the bottom of the filter case. So, that longer hose would make access to that a lot easier. Of course you should write that stuff down and file it, so that it is handy.

Because the filters sit in their own case, you don’t have to drill holes in the cabinet or the drain pipe like some other filter systems.

Unlike some reverse osmosis and other systems, you don’t need a special faucet that has an air gap in it.

Do make sure that you mark the end of the hose at 3/4 inch and that when you push the hose into the fittings that the hose goes in up to that mark. Then tug on the hose to make sure it is properly seated.

When To Change The Filters

The Filter Life Indicator measures the amount of water used, instead of just being a timer like most systems.

The indicators will be a dim blue color when the filters are new. They will change to white during use and eventually to red when the filters need to be changed.

You will get 1,665 US gallons of use before needing to change filters. That’s 6-12 months for most families.

How To Install and Change The Kube Filters

First, let me tell you how to put the filters into the Kube, because removing the old filters is just the opposite.

The blue bypass lever should be in the down position, which lets the water flow (bypass) the filters as if the Kube water filter system wasn’t even installed.

To install a filter, line up the raised rib on the filter cartridge with the slot in the Kube case and push it in until it stops. Then twist the filter cartridge clockwise a quarter turn. The raised rib should now be lined up with the “locked” symbol.

After both filters are in, turn the blue bypass lever upwards. Don’t force the lever. If the lever doesn’t move easily, that means the filters aren’t properly installed. When the bypass lever is in the “up” position the water will flow through the filters.

To replace the filters, turn the bypass lever to the downward position and remove the old filters. Insert the new filters and turn the bypass valve to the “up” position.

Now run cold water in the sink for 5 minutes, and then turn it off and wait for 10 minutes, then turn the cold water back on for 3 minutes, and then shut it off. This cleans the loose carbon dust from the filters, removes air from them and resets the filter usage indicators.

Then pull out the plastic tray at the bottom of the Kube and dump out the water it collected during the filter change. Now drink some really great water.

Can I Hook Up To A Separate Faucet Or Refrigerator?

Sure can. You will need to buy some extra parts, but the installation is really simple.

You will need a “T” hose fitting to feed the refrigerator in addition to the sink or dedicated faucet.

If hooking up to a dedicated faucet, you will need a Dual Outlet Stop Valve  or something similar to continue water going to your sink faucet and to the Kube. Then the Kube is hooked up to your dedicated faucet, just like shown in the video.

Here again you can use a “T” to hook up the inlet hose to your refrigerator. Be sure to remove your current refrigerator filter. That might also require a bypass plug  that replaces the original refrigerator filter.

Essentially the bypass plug replaces the unwanted filter so that water doesn’t leak everywhere.

Leaving the old filter in the refrigerator will cause bacteria to grow and would reduce your water flow also.

You Can Bypass The Kube When Using The Kitchen Faucet

If you have the standard installation to the kitchen sink faucet, you can turn off the filtered water by turning the bypass lever to the downward position. That way you are not using filtered water for something that it isn’t needed for.

Can I use This With Well Water?

Only if you are using a sediment prefilter, an iron removing filter, and a water softener before using the Kube water filter.

Also, if you have any bactera in your well water that will have to be removed also. Usually an ultraviolet light is the best choice for that.

The Kube water filter system is designed for city provided tap water.

The 2 Year Limited Warranty

It covers materials and workmanship, where if you send it back to them they will repair or replace any defective part. However, you must register your purchase within 30 days. The instructions will tell you how to register.

Some Final Thoughts On The Kube Water Filter

I have written a lot of product reviews and the Kube has a lot to offer at a reasonable price.

The ease of installation – no drilling holes in the cabinet or drain pipe is a big advantage.

Also, the simple clean filter changes that don’t require plastic wrenches or crawling under the kitchen sink is another big reason to buy the Kube by using the link below.
