Express Water WH300SCKS Water Filter

For anyone specifically looking for a 3-stage filtration system, the Express Water WH300SCKS is a great alternative to the Aquasana EQ-1000 model. Like its competitor, it offers a comprehensive solution to water contamination in one single unit.

Read now:

The system uses three different filters to target and remove specific contaminants from the water supply and to ensure a more complete purification process. The first stage consists of a sediment filter which eliminates coarse damaging contaminants such as dirt, rust, and sand.

The filter has 4 distinct layers capable of removing contaminants down to 5 microns with the outer layers catching the coarsest contaminants while inner layers deal with finer sediments and particles.

The second phase consists of a Kinetic Degradation Fluxion filter which further captures heavy metals contaminants as well as dirt and other suspended particles. It also removes chemical contaminants including VOCs.

The final stage completes the filtration process and it’s where all the chlorine, chemicals, pharmaceuticals, pesticides and Total Organic Carbon (TOC) are removed using a granular activated carbon filter to ensure that the water tastes good and is drinkable.

Another thing that sets this unit apart is the pressure gauge and the pressure release button that it comes with. They make it easier to use and monitor the system so that you are aware of when the filters need replacement.

The whole system is a heavy-duty construction made from quality food-grade PCE and ABS plastic, so as far as durability is concerned, you are not going to worry that much. You will have no problem when it comes to installation and maintenance is also quite easy due to its user-friendly design.


  • Offers a much more comprehensive filtration capability
  • Heavy-duty, durable construction
  • Water pressure is a high ideal for large houses
  • Stainless steel housing for easier filter changes
  • Installation and maintenance is fairly easy

Our Verdict

The WH300SCKS whole house filtration system from Express Water provides a solution to a wide variety of water problems and once you install it, you are definitely going to appreciate the results and performance.

If the Aquasana EQ-1000 model didn’t win you over, then this might be a nice alternative.
