This review is all about the PIONEER, a whole house water filter system manufactured by ENPRESS. What makes the PIONEER special is that it’s the only whole house water filter we know of that could earn an NSF 53 certification for guaranteed lead removal.

If you check the actual lab data you’ll find that the system has proven to reduce 99.62% lead for a full 100,000 gallons of water. Now, 99.62% lead reduction for a whole house application is pretty darn good already. But it’s not the end of the story…



Filter Capacity:100,000 Gallons
Water Flow Rate:Up to 8 gpm
Annual Cost:$350-400
Warranty:1 Year

PIONEER Whole House Lead Water Filter – Key Features

First of all, what does the PIONEER do different to be the first whole house water filter to have earned an NSF 53 certification for lead removal?

Simply put, it removes both particulate lead and soluble lead from water:

  • Particulate lead is what numerous other (whole house) water filters can adsorb, too. All that’s needed is enough activated carbon filter media. That said, the PIONEER might still be much more effective at removing particulate lead that its competitors. We couldn’t tell since the manufacturers of all the other whole house water filters on the market have never provided any performance data. Anyway, the PIONEER removes particulate lead down to 0.5-micron (nominal).
  • Soluble lead is harder to catch. It requires chemical removal. The PIONEER uses special binders designed to react with the soluble lead in water to create an ionic (electrostatic) bond.

Bottom line: The PIONEER was tested for both forms of lead. And it was tested at a standard flow rate of 4.51 gallons per minute (gpm) as well as 8 gpm peak flow. ENPRESS says you’ll get 99.62% lead removal at both flow rates.

8 gpm should be enough for homes with 2, maybe 3 bathrooms – it always depends on how many water outlets you use at the same time.

By the way, the whole house water filter was also awarded an NSF standard P473 certification for PFOA/PFOS removal (97.9%). Both PFOA and PFOS increase the risk of cancer. Data estimates that at least one of the substances can be found in the water supplies of more than 100 million Americans so not a bad idea to have those taken care of.

On top of that, the PIONEER filters cysts (>99.95% NSF 53), chlorine, chloramine, other heavy metals apart from lead, bad taste, and odor.

Operating pressure: 20-125 psi

Model number: CTA0840BBBKP5-04C00


More pros:

  • The PIONEER uses a water meter to tell you via an easy-to-understand LED system when it’s time to replace the filter cartridge inside. Green light means all is good. 3 yellow LEDs indicate the remaining filter life is less than 10%. Red light means you have to change the filter asap.
  • Water meter + LED system require a power outlet which is backed up by batteries in case of power failure.
  • SpringWell Water who sells the whole house water filter gives you a 6-month satisfaction guarantee which allows you to test the system risk-free.
  • There’s a 1-year warranty on the system itself and 30 days on the filter cartridges.

The good news is the system comes preassembled for the most part, plus it includes a bypass. So installation isn’t more difficult than hooking up any other whole house water filter which is a great opportunity to save if you’re a DIYer.

Just make sure to not use extra lubricants, unapproved sealants, or tools (all parts are hand-tighten only). Otherwise the warranty voids.


  • CTA0840BBBKP5-04C00 system
  • Filter cartridge
  • Bypass valve
  • 1″ MNPT fittings


We’ve already mentioned the LED notification system. When the light is red all there is to do is changing a single filter cartridge – easy as pie with no tools required.

You just have to remember to also replace the 3-AAA batteries, reset the meter (hold down reset button for 3 seconds, LED lights will flash 3 times to confirm reset), and flush each new filter cartridge for 10 minutes prior to use.

This shouldn’t be required too often, though. The filtration capacity is 100,000 gallons or 1 year.

Cost? Between $350-400 per cartridge which is absolutely fine for a whole house water filter.

One might argue that the PIONEER whole house water filter seems overpriced. And it’s reasonable criticism. However, we must not forget that there really is nothing comparable to it. Above that, the maintenance cost is just fine for what you get.

What’s more, 8 gallons per minute peak water flow might not be enough for larger homes.

PIONEER Review: Our Verdict

The PIONEER whole house water filter is not exactly cheap. Yet it’s the only whole house water filter independently tested and certified for lead reduction according to NSF standards. The same goes for PFOA/PFOS and cyst.

All in all, it’s our top pick for people who want access to lead-free water at every tap in their home. 5 stars!
