Review of GE Whole House Water Filtration System

Please follow us on

Water DropsA couple of years ago we decided to do a large bathroom renovation project.  My husband had been toying with the idea of running new water pipe throughout the house, so we decided that this would be the best time to do it.  Having all the floors and pipes torn up was the perfect excuse to “get stuck in”.  We removed the old water heater and replaced it with a much smaller demand feed system.  After painstakingly crawling under the house, again and again, my husband removed all of the PVC pipe and replaced it with Pex tubing.

With all of that hard work, there was no way we were not going to look after the new system, so we installed the GE Whole-Home GXWH40L Heavy-Duty Water Filtration System.  For the most part, this was to protect the demand feed heater.  However, as we live in a rural area, surrounded by farm fields, it gave us the added peace of mind of filtering out the pesticides that soak into the water table.  It also does a grand job of filtering the clay and sediment that somehow, always manages to get into the pipes.


This is not the highest rated, best option of the whole house filtration systems, although it does come in as #6 out of 10 in the architects guide for 2019.  There are other systems, three tiered and more, that are bigger, better and filter many more components, but for our needs, and more importantly, our budget, this system works as advertised.  We’ve been very happy with it so far.

The ProsShower Head

  • Premium filtration reducing sediment, rust, dirt and scale
  • High flow rate  40 – 100 psi feed pressure tolerance
  • Bi-pass valve to help increase filter life when filtration is not needed
  • Cannister wrench included for easy filter changes
  • Comes with heavy duty wall mount
  • Inexpensive
  • Easy Installation

The Cons

  • Does not come with filter (must purchase separately)
  • Some reports of diminished water flow/pressure
  • Built in check valve can cause water hammer/pipe knock with some plumbing

Water GlassReading through the various reviews of other users, the pros seem to outweigh the cons on the GE Whole-Home GXWH40L Heavy-Duty Water Filtration System.  The only problem that we have had is a limited flow of water to the bath in our main bathroom.  All the other faucets in the house, including two other bathrooms, work just fine with no pressure problems.  Two separate showers can be in use and the washing machine and dishwasher with no restrictions.  The bathtub is a different story and it may have nothing to do with the filtration system at all.  I do like the clear canister on this system.  It lets me know that the filter is doing it’s job and it does it well.  We have had no problems with the built in check valve that others have had.  No water hammer or pipe knock.

The replacement filters are easily purchased from  Given our area and usage, we tend to get roughly 3 months out of each filter. You can buy generic filters that are less expensive than the GE brand that are compatible.  Just be very careful and make sure they fit “exactly”.  We tried the Aqua Crest brand that said it would fit our model GE system and it did not!  It was just a fraction of an inch too tall not allowing the canister to seat properly.  Two attempts, a shower and a very wet wall and floor told us it was a bad buy.

The system itself is great.  The filter cartridges can be a bit pricey but there are options.  Over all I think the GE Whole-Home GXWH40L Heavy-Duty Water Filtration System is an all around good purchase.

Do you have a similar system or are you interested in buying one?  Please leave me a comment in the section below.  Thank you.

    This is a very well written and accurate review of the GE Whole-Home GXWH40L Heavy-Duty Water Filtration System. I have used a 2 filter system in the past but did not think that was required in our area. I am very happy with the ease of maintenance and the performance of the GE Whole-Home GXWH40L Heavy-Duty Water Filtration System.
