These 7 GE under sink water filter choices will fit the needs of just about everyone who is worried about their city tap water or well water.
The GE brand is well known and respected, which is why you are here. They have provided 7 popular under sink water filter systems, and I will help you to select the best GE water filter for your home.
All of the GE under sink water filters have been certified by NSF to perform as expected. 
Although two of the filters are meant to be used right after your water meter or your well’s pressure tank, you might have a reason to put them under the sink.
Also, I have provided reviews of the replacement water filters that can be used with these under sink filter systems.
Fast Overview Of The GE Under Sink Water Filter System Products
First, let me say that one GE under sink water filter system is not necessarily better than the others, depending upon your needs. So, although they are numbered 1-7, that is for your convenience.
#1 Choice: GE Reverse Osmosis Under Sink 3 Stage Water Filtration System GXRM10RBL. Reverse osmosis will remove many more contaminants than any other system. Which makes it out #1 best choice of the GE under sink water filter products. However, it’s not as easy to install or to replace filters.
#2 Choice: GE Dual Stage Drinking Water Filtration System GXSV65R . This is the the second best choice over all and the most expensive. The reverse osmosis product is our best choice, and is less expensive.
#3 Choice: GE Under Counter Dual Flow Water Filtration System GXK285JBL . Our third choice is essentially the same as the second choice. It has an on/off knob instead of a dedicated purified faucet. At about half the price of the #2 product, this is a good choice if you already have an extra faucet, or don’t want to use an extra faucet.
#5 Choice: GE GX1S01R Drinking Water Filtration System
#6 Choice: GE Standard Flow Whole Home Filtration System GXWH20S . Many customers use this clear view housing to prefilter water from their wells.
Reverse osmosis filtration is the best remover of all toxins known to man.
Also, it is less expensive than our #2 choice.
There are only three filters in this system. Whereas other reverse osmosis systems have as many as six filters.
TYhe GE GXRM10RBL RO system is designed for use with city water. However, it could be used with well water if you have a whole house water filtering system in place already.

When and Why To Change Water Filters
It comes with a dedicated filtered water faucet that has a reminder light to tell you when to change filters. The necessary batteries are included. However, the reminder light is just a timer and doesn’t actually reflect when a filter needs to be changed.
But, there is a reason to change the carbon filter every six months. That’s because bacteria can multiple in a carbon filter and changing the filter will prevent bacteria growth. However, the reverse osmosis filter will filter out bacteria, but you don’t want to depend upon that. Also, all that bacteria will plug up the membrane much too fast, which will cost you more money in the long run.
Another reason you don’t want bacteria growing in the filters is the possibility of that bacteria spreading through all the water pipes and coming out where you don’t have a filter. Like the bath tub, shower, washing machine and dishwasher.
Some customers change their canister filters every 3 or 4 months, because their water has more contaminants than other people have.
At least one customer changes the reverse osmosis filter every two years and another waited until five years. Whereas GE recommends changing the membrane every year.
Another customer said that his membrane filter lasted 12 years.
GE Reverse Osmosis Under Sink Water Filtration System GXRM10RBL Installation
Can I Install The Ge GXRM10RBL Reverse Osmosis System In The Basement?
Yes. However, you want it close to the sink where it will be used. That way the additional length of the hose will not lower the water flow rate.
Can I Use This With My Refrigerator?
Ya, sure, you betcha! Just add a 3/8 x 3/8 x 1/4 t-fitting to the blue hose that goes to the faucet. Any hardware store will have what you need.
How Many Gallons Will It Produce Per Day?
About 10 gallons. One household of 3 people said they never ran out of water when using it to drink and cook. The one drawback of this system is that it wastes a lot of water, which goes down the drain.
How Much Water Pressure Do I need?
The minimum water pressure needed is 40 PSI according to the manual (maximum of 120 PSI). However, you might still get water at a reduced flow rate if your water pressure isn’t quite 40 PSI.
But don’t push that minimum pressure limit, because the membrane filter is designed to work under pressure. If there isn’t enough pressure, no water will flow through the membrane.
Perhaps the most popular choice is the GE dual stage under sink water filter system GXSV65R. It’s certainly the best combination of easy use, maintenance and performance.
The dual filters provide a faster (0.6 gpm) water flow than most other water filter systems. This is especially important for home with already low water pressure.
You’ll be glad to know that it removes dangerous lead and, cysts. As well as, chlorine smell and taste problems. See the full list below.

GE Under Sink Water Filter Installation
Installation is pretty easy. Just follow the instructions and it should look something like this:
Some people also hook up their refrigerator water dispenser and ice maker by splicing in another hose. You can make that connection anywhere between the “outlet” and the supplied metal water faucet.
Simply place the filter manifold on the cabinet wall as shown in the diagram below and mark where the screw holes are on the cabinet. Then drill a hole, smaller in diameter than the screws, and then screw in the screws and place the manifold onto the screws.
When Do You Change The Filters?
Two filters come with the device. However, it would be a good idea to have replacement filters on hand before you need them.
You want the GЕ Under Sink Water Filter FQSVF Smartwater Cartridges shown on the right.
There is a light indicator that tells you when the filter has been used for six months and should be replaced. This is just a timer and does not actually measure any usage.
Officially, GE says these filters will last for 160 gallons of water.

Depending upon the source of your water, the amount of contaminants, and how much water you use, the period of time between filter replacements will vary.
Both filters are identical. So, don’t worry about placing one before the other. Also, the filters will work with these GE products: GXSV65R, GQSV65R, GXSV65F and GQSV65F, GXSL55R filter systems.
At half the price of the above system, the GE GXK285JBL Under Counter Dual Flow Water Filtration System doesn’t have a separate water faucet.
Instead it connects to the waterline of your existing faucet. However, unlike many competitors, the filters are only activated when you turn the control knob.
The control knob is mounted where the soap dispenser or extra water faucet would be.
Can I use My Existing Filtered Water Faucet Instead Of The On/Off Knob?
GE Under Counter Dual Flow Water Filtration System GXK285JBL. Easy Twist And Lock Filter Changes – Check the price at Amazon.
Yes! If you want this filter system, but keep your second faucet, you can. You will probably need to make some simple adjustments to connect the hose to your faucet. That should only cost a few dollars in extra parts from the hardware store.
Otherwise, everything needed to install is included.
Using The GE Dual Flow Water Filtration System
The on/off knob is mounted onto the kitchen sink counter top where it is easy to reach.
This knob lets you use filtered water when you need it. That way you save money by not using the filtered water when it isn’t needed.
After turning on the filtered water, be sure to let the water run for a few seconds to remove unfiltered water from the faucet.
Because of the dual flow double filter system you get more than one gallon of filtered water every minute. That is double the the water flow of most filter systems.
What Do The Different Warning Lights Mean?
The double flashing light tells you to replace the filters (both of them). However, if the light is fading, that means you need to replace the battery also. Once you have replaced the filters, you will want to turn off the warning light.
How Do I Reset The Filter Change Warning Light?
The little square box contains the filter change warning light, which operates on a battery. So, you don’t need any electrical source to use the filters.
To reset the filter change warning light, just press the blue reset button for five seconds.
Do I Need To Use The 6 Month Timer Light?
No you don’t. Its only function is to act as a 6 month timer to tell you when to change the filters. It is handy as a reminder. However, you could just write the date on the filter for when to change it. Especially if you change it more often or less often than 6 months. Also, it’s another battery you don’t have to buy.
There is a one year limited warranty through GE Appliances.
This GE under sink water filter connects directly to the cold water line for your faucet.
Which means that all of the water coming out of your faucet will be filtered. If that isn’t what you want (shortens filter life), then you will need a dedicated faucet for this filter.
Simply use a “T” shaped diverter to run cold water to your faucet as normal and also to your additional faucet for filtered water.
This filter will not be able to handle very hard water or water with a lot of sediment or high amounts of contaminants. Which is why some people have given this product poor reviews.
In such cases, this would work if you have sediment prefilters, and other filters as needed. Such as a water softener to remove the hardness.
This is a carbon block filter. All carbon block filters should be replaced every six months to prevent bacteria from growing in them. Carbon filters remove an impressive number of contaminants from your water.
This is the housing and bracket holder only. You must also buy a filter separately.
You can connect this directly to your kitchen sink faucet cold water pipe. However it would be longer lasting if you used a separate faucet for this filter.
The “In” and “out” ports are clearly marked on the housing, which accepts 1/2 inch pipe fittings.
This filter will remove chlorine and sediment, and as set by NSF/ANSI 42 standards.
It is designed to remove chlorine taste and smell and sediment.
You can expect one gallon of water per minute when the filter is new. As the filter gets used more the flow rate will drop (perfectly normal for all filters).
When the flow rate is less than you like, then change the filter.
Some customers claim that this filter no longer fits, because it is a bit longer. That was a design change that improves it sealing ability.
Other customers claim that the filter is now not fitting, because the filter is slightly wider. They say the Denali Pure filters do fit properly.
Will filter out chlorine, lead, mercury, cysts, asbestos and more for 600 gallons.
Like the above filter some customers say that this filter no longer fits. So, once again, you should probably buy the Denali Pure filters.
This clear see through filter housing and filter combination is very popular and well liked.
NSF/ANSI 42 certified to remove yucky looking rust, and the sand and sediment that damages your appliances.
The Amazon listing says 30,000 gallons, but a close look at the package shows that it is rated for 16,000 gallons. Also, it filters down to 30 microns to trap sand, dirt, and other sediments.

The pressure relief button and the bypass control handle will make filter changes easier.
Also, the magnetic filter change alert light sits right on top of the filter to remind you when to change the filter. It runs on one AA battery and the blue LED bulb blinks when 3 months have gone by.
The housing takes 3/4 inch fittings. To make this installantion easy and leak free, get two of these SharkBite fittings . Screw the (Teflon taped) threaded ends of the SharkBite into the filter housing, and then simply slide your copper pipe of plastic PEX pipe into the other end. That’s it – done.
However, you should also get a SharkBite Ball Valve to shut off the waterline after the filter. That way when you change filters the water in the pipes won’t leak all over the floor. If you are any distance away from the water meter shut off valve then put in another ball valve in front of the filter as shown in the GE image above.
When you install the filter into the housing put some food grade Silicone Faucet Grease on the housing threads. This will make removing the housing to change the filter MUCH easier. You’ll thank me for this tip.
These fit the Choice #6 filter housing above. These filters will remove chlorine that causes your water to smell and taste bad.
Also removes rust, sand and other sediments.
These filters will effectively filter 30,000 gallons of water. Which should last about three months.
This is a PolySpun filter that is rated to last for 3 months or 16,000 gallons.
It filters out sediment that is 30 – 50 microns in size. So, if you have a lot of rust, sand or dirt in your water, you’ll want this filter in front of the carbon filter shown above.
This is a standard size filter that is 10 inches (long) x 2-1/2-Inches (wide)

Customers love these for removing rust, sand, and sediment from their well water down to 30 microns.
They are rated to last for three months or 30,000 gallons. Which is what the customers are also saying.
One customer said they had heavy calcium and iron in their water and that the FXWPC filters work great.

These filters are the bound string type of water filters – unlike the more solid looking or pleated looking one.
They are NSF rated for removing rust, sand and sediment down to 30 microns for 16,000 gallons. Which would be about 3 months of use.
However some customers that were treating well water were changing the filters every month or two.
