GE GX1S50R Under Sink Water Filter Reviews

The GE GX1S50R is a small, simple under sink water filter but packs a commendable punch as far as removing contaminants in the water is concerned. It’s an excellent choice for reducing chlorine and undesirable particles from lowly-contaminated municipal water.

Filtration Performance

Water entering the GE GX1S50R water filter system from the cold water supply goes through a single-stage filtration process inside the filter cartridge where several different kinds of contaminants are extracted from it.

The system uses a high quality activated carbon filtration media which removes up to 97.6% of chlorine, and negative tastes and odors. This medium is also able to clear out 99% of lead and filterable cysts like giardia and cryptosporidium.

The other contaminants it will remove from your water include turbidity, asbestos, lindane, atrazine and heavy metals like mercury.

If your water often comes out with small particles suspended in it, then this General Electric filter will as well come in very handy.

Alongside removing most of the chemical contaminants, it’s capable of trapping nominal particulates down to 0.5 microns which clears out 98.8% of dirt, rust, sediment, sand, silt and any other particulate present in the water.

It’s basically a dependable and reliable single-stage filtration that can supply fresh, filtered water but only for use with already treated water like from city treatment plants. We wouldn’t recommend it at all for filtering well water.

Filter Capacity and Efficiency

The GE GX1S50R filter cartridge can process a maximum of 750 gallons of water before it can be replaced. It’s a low capacity unit but if you are processing 4 gallons of water a day, then it can work effectively for up to 6 months.

 Water comes out of the faucet at a maximum flow rate of 0.75 gallons per minute which again is not that high but will do fine for low-demand usage.

Installation and Maintenance

You can successfully install this unit with some basic DIY skills. It uses a separate dedicated chrome faucet which will require drilling a mounting hole into your countertop but once you are done with that, the rest is straightforward. The filtration system is a single filter unit with a small footprint, so it will fit anywhere, even in tight spaces.

The filter head features a twist and lock design that makes replacing the filter cartridge equally fast and easy.

You will have to change it at least twice a year and to save you from guesswork, General Motors has integrated a filter life indicator with a reminder light on its dedicated faucet. It will conveniently remind you when it’s time to replace the filter cartridge to maintain the best filtration results.

Overall, if you need a water filtration system purposely for filtering out chlorine, lead and unpleasant tastes and odor, then you may consider getting this GE GX1S50R under sink water filter.

Pros

  • Good for removing chlorine taste and odor
  • Can trap nominal particulates down to 0.5 microns
  • Average filtration capacity of 750 gallons
  • Easy to install and has low maintenance
  • Faucet features a filter life indicator
  • Comes with a 1-year limited warranty

Cons

  • Shorter filter life and low filtration rate
  • Not recommended for filtering well water

Whirlpool WHAMBS5 Under Sink Water Filter Reviews

The Whirlpool WHAMBS5 is the last model on our list but certainly not the least. Coming from a company that has been in the industry for the longest time, this model is a quality yet budget-friendly under sink water filter system that provides the necessary filtration capability to keep your municipal water clean and safe for your family’s daily usage.

Filtration Performance

The Whirlpool WHAMBS5 utilizes a 3-stage filtration process that’s certified to NSF/ANSI standard 42 and 53 to remove numerous harmful and undesirable elements in tap water.

The 1st stage is a standard 10” sediment filter cartridge with a specialized design meant to trap incredibly tiny sediments and particles from the water

It will clear out rust, dirt, silt and other particulates down to 0.5 microns thereby preventing the filter cartridges in the following two stages from clogging.

The 2nd stage consists of a standard 10” carbon block filter cartridge which removes up to 99% of lead in the water and as well serves as the pre-filter to the 3rd stage by reducing a good amount of chemical contaminants that cause unpleasant odor and taste.

The 3rd stage features a much bigger filter cartridge compared to the other two stages and it’s the heart of the system. It holds a larger top-quality activated carbon block filtration medium that provides a higher surface area than standard carbon-based filters.

The larger surface area significantly enhances its adsorption ability allowing it to effectively eliminate greater amounts of chlorine (up to 97%) and many other chemical contaminants such as benzene, pharmaceuticals, pesticides, insecticides, herbicides, and industrial solvents. It will also clear out all the bad odors and tastes caused by these chemicals. 

Moreover, this large activated carbon filter conforms to the NSF Protocol P231 for the reduction of microbiological contaminants. Therefore, it will equally serve as a microbiological purifying filter with the capability of removing at least 99% of bacteria, microbial cysts, and viruses.

The three stages will remove all the above contaminants and much more but at the same time, it will leave the natural essential minerals found in the water giving you healthy, great-tasting purified water.

Filter Capacity and Efficiency

Whirlpool has rated this model to process a maximum of 550 gallons throughout its lifespan which puts it in the same category as the other low capacity models we’ve reviewed.

Provided you process around 2 to 4 gallons of water per day, you can expect to receive 4 to 6 months of reliable filtration performance before you replace it with a new filter cartridge.

For the water flow rate, it stands at a maximum of 0.74 gallons per minute, so also expect a moderate delivery speed, a little bit slower than that of your regular cold water kitchen faucet.

Installation and Maintenance

The Whirlpool WHAMBS5 system comes with a dedicated filtered water faucet that needs to be mounted on your countertop.

If you have an available faucet hole, you will have an easier time setting up the entire system, otherwise, you will need to drill one which is the only tricky part especially for first-timers. The unit holding the three cartridges is compact and will fit neatly in any standard-sized under sink kitchen cabinet.

You won’t break a sweat either when it comes to replacing the filter cartridges since they use a twist-in design. It requires just a simple ¼ turn to release the old filter, then pulling it out and replacing it with the new one. 

You don’t need to turn off the water supply plus the faucet is equipped with an amber LED indicator that monitors the filter life after installation.

It will flash continuously once the 6 months have passed to alert you that the filter cartridges and battery need changing hence saving you from getting caught off guard. 

Though the filtration capacity and water flow rate leave a lot to be desired, we can comfortably say this Whirlpool WHAMBS5 model is a very decent and well-made under sink water filter system. It’s a nice budget option for those who wish to enjoy safer, better-tasting water without making a big dent on their wallet. 

Pros

  • Rigorous filtration process removes numerous contaminants
  • Capable of removing microbiological contaminants like bacteria and viruses
  • Won’t interfere with the natural essential minerals in the water
  • Installation is relatively simple while filter replacement is a breeze
  • Faucet has an amber LED indicator that alerts when to change the filters
  • Backed by a 1-year limited manufacturer warranty

Cons

  • Filtration capacity is low at only 550 gallons
  • The speed of water flow is low too at 0.74 GPM
