The Truth about Filtersorb SP.

Scale Prevention or Scale Deception?

How does nextScaleStop compare to Filtersorb SP?
Next Filtration Technologies Inc., the distributor of nextScaleStop claim that nextScaleStop operates via a similar mechanism as Filtersorb SP. However, our tests of the nextScaleStop's physical and chemical composition, combined with field test results clearly indicate that nextScaleStop  is in no way equivalent.

If it’s not equivalent to Filtersorb SP, what is it?
Based on our initial analysis, nextScaleStop appears to be buffered Weak Acid Cation resin that has been partially converted from the Hydrogen form to the Calcium form.

Do you have other evidence to support claim?
The chemical profile combined with the SEM analysis is consistent with the properties of TAC resin.
Further evidence is provided by the requirement that nextScaleStop "rest" periodically. The need for "rest" is defined as 8 hours per day if used in a residential application or for no more than 4 hours of continuous use without "resting" in commercial applications. This is consistent with the behavior of an absorptive media that would recover some of its capacity after resting due to diffusion into the pores of the media. The need for "rest" is completely inconsistent with a media that claims to catalytically create crystals. If the media is truly "not used up" in the reaction, and if the media behavior is consistent with any known crystallization mechanism, there should be no requirement for "resting".

Next Filtration Technologies Inc. claims that nextScaleStop has been proven effective for 5 years in USA. How can this be true if the media works as described above?
The claims of years of experience with nextScaleStop are false. nextScaleStop was manufactured for the first time in May 2006. It’s also worth noting that since its release in May 2006, there have been 3 "new" formulations or versions of the product.

Would a product proven with years of experience need 3 revisions in less than 2 years?

Does nextScaleStop work as a de-scaler and scale prevention media?
Weak Acid Cation resin is a proven scale prevention method. It is routinely used in disposable cartridges for treating water used in low volume devices such as espresso machines and coffee brewers. As used by Next Filtration Technologies Inc., nextScaleStop may provide de-scaling effects (due to a temporary reduction in pH due to the release of Hydrogen ions) as well as temporary prevention of scale formation through the combined effects of pH reduction and Calcium adsorption.
The important thing to note is that these effects are temporary. Once the resin is fully loaded with Calcium, both the de-scaling effect and the scale prevention effect will stop.

There have been reports of some evidence of crystal formation with nextScaleStop. How do you explain that?
When the nextScaleStop bead becomes loaded with calcium, the calcium on the bead will serve as a very weak nucleation site. Accordingly, under some conditions, nextScaleStop will produce an extremely small volume of crystals, but nowhere near enough to provide effective scale prevention.

People claim to have had success with nextScaleStop, especially in residential applications. Do you have an explanation?
Yes. It’s important to note that residential applications are highly subjective. With that in mind, the answer is two-fold. First, when the system is new, the scale prevention benefits they promise will occur due to the characteristics of the TAC resin. Second, because the systems are almost always sold with a whole-house carbon filter, the customer perceives the combined effect of improved taste and reduced scale as attributes of the "system". As the ion exchange capacity of the resin is depleted and the scale prevention benefits decline, the customer may not notice change in performance. This is due to the gradual nature of the decline, combined with the gradual formation of scale and the time it takes for the scale to become noticeable. Plus, because the carbon filter is still delivering improvements in taste, etc., the system is perceived as "working".

I’ve seen claims of success on objective equipment-based tests. Can you offer an explanation?
Yes. All of the "testimonial" and references that we've seen that were provided to prospective customers as "proof" of performance have been for tests of extremely short duration, usually covering just a few weeks of testing on new systems with fresh media. Further, these testimonials have been so lacking in detailed water quality measurements that they are anecdotal at best.

As noted before, nextScaleStop does work as a de-scaler and scale prevention media, but only for a short period of time!

Summary.
Our current understanding based on an on-going analysis of the media and it’s performance, is that nextScaleStop does not act via the mechanism claimed by the manufacturer, and does not deliver the benefits they claim. As previously noted, nextScaleStop does offer short-term de-scaling and scale prevention performance that deteriorates and eventually stops after a short period of time (consistent with the characteristics of TAC resin).

If you’re interested in a true proven, alternative scale prevention system, please consider: Filtersorb SP.
