For homeowners who care about the quality of their water, look no further than L'eau Mor's Geaux Flow Under Sink Replacement Filters. Our advanced four-stage filtration system purifies water at the source, ensuring your family enjoys safe, clean, and refreshing water for all uses.

Starting with a 20-micron pre-filter that removes larger sediment and particles, our Stage 1 filter is designed to provide maximum protection from contaminants. Upgrade to our Stage 2 chemical filter for utmost purity - eliminating heavy metals, chlorine, and volatile organic compounds. When you're looking to specifically address an issue like iron or fluoride in your water supply, choose one of our specialized Stage 3 filters: an iron/sulfur filter or our Stage 3a Filter which specifically removes fluoride.

With our Replacement Filters, you can enjoy the best quality of water while knowing it is never compromised by dangerous contaminants.

Please note:  When you replace any filter, you must replace Stage 1 as well. 

For example: 

  • You need to replace Stage 2, then you will need to buy Stage 1 and 2 
  • You need to replace Stage 3, then you will to buy Stage 1 and 3 


*For your convenience, our pricing begins with our Stage 1 water filter.  If that is the filter you need to replace, then simply check out or subscribe to that filter.  

Choose your replacement based on the water filter system you have and the type of issue you are targeting.

*If you have a single-stage system, choose the stage 1 replacement option.

*Stage 2 Filter - chemical filter is always chosen for this stage.

*Stage 3 Filter - choose between the iron/sulfur filter OR the fluoride filter for your system.  

While the image looks the same, the contents of each Stage vary according to what you wish to remove.
