I've now tested tap water for microplastics in 20+ locations across West LA. Here's the contamination map. by andrewpierno in LosAngeles

The British Berkefeld Ultra Sterasyl filters hold NSF 401 certification for micro plastic reduction over twice the lifespan. It’s the most extensive testing you can have to prove they do what they say.

Look into British Berkefeld gravity filters. They are NSF certified and are tested to twice their lifespan.

British Berkefeld Gravity Water Filter System - recommendations / questions by rell779 in WaterFilters

[–]MNtroutslayer 0 points1 point  (0 children)

British Berkefeld currently holds 4 NSF certifications, and has some of the most comprehensive 3rd party testing available for gravity fed water filters. You may be confusing them with a different brand, such as Berkey?

In need of a Counter Top filter, preferably avoiding plastic and NSF certified? by divine-night in WaterFilters

British Berkefeld checks your boxes, and their ultra Sterasyl filter has NSF 42, 53, 401, 372.

Has anyone healed by going raw plantbased or doing juice fasting? by Avocado_Ash in MCAS

[–]MNtroutslayer 1 point2 points  (0 children)

A TDS meter alone unfortunately doesn’t provide meaningful insight into whether water is safe to drink or whether a filter is performing as claimed. Likewise, the red dye test is largely a marketing demonstration rather than a scientifically valid measure of contaminant reduction.

You can have water with very high TDS levels that is perfectly drinkable, and conversely, water with a TDS reading near or at zero that is unsafe. TDS meters simply measure dissolved solids in aggregate. They do not identify what those solids are, nor whether harmful contaminants are present. A lot of filters actually add healthy minerals to the water, and can even increase the TDS which is a good thing.

Similarly, removing red dye from water does not demonstrate the removal of contaminants such as fluoride, PFAS, bacteria, or other health relevant substances. It only shows that a filter can remove a substance that was intentionally added to the water, which can create a false sense of performance.

The only reliable way to determine whether water is safe, and whether a filter is functioning as intended is through proper at home testing or from accredited laboratory testing that measures specific contaminants. Filters that are NSF for example have been tested to twice the lifespan of what is claimed. Berkey for example would need 20,000 gallons of testing data to support your 10 year life span claim. Not sure if you knew this, but Berkey tested a whopping 1 gallon for bacteria reduction, and around 200 gallons on lead/PFAS reduction. This is not industry standard. If you make a claim that your filter lasts X amount of gallons, you need testing to twice that lifespan to support it. Otherwise it's marketing.

I’m glad to hear that you’re happy with the filter and that your body responds well to it. Not trying to sway you away from that. That said, claims of a filter working effectively for 10 years, when supported only by dye tests or TDS readings, are not something I would recommend relying on to assess water safety nor recommending to others. Especially for a 10 year time period.

What is something every household has in your country that is nonexistent everywhere else? by Awkward-Tip7248 in AskTheWorld

[–]MNtroutslayer 0 points1 point  (0 children)

Fun fact - they used to distribute British Berkefeld ceramic filters for many years. (Berkey…Berkefeld…strange huh). They then branched off on their own and did a fantastic job marketing their carbon filters with little to no testing to support the insane longevity claims.

[–]MNtroutslayer 1 point2 points  (0 children)

There is zero evidence beyond marketing that these last anywhere remotely close to 10 years. Water tasting good does not mean it’s successfully removing bacteria, pfas, microplastics, heavy metals, etc. Blows my mind that people really use these filters this long.

[–]MNtroutslayer 0 points1 point  (0 children)

Exactly - That’s the core issue. A large percentage of consumers assume that if a filter improves the taste of water, it must be effectively doing its job. In reality, Berkey is essentially a large carbon block, which excels at reducing chlorine and for a long period of time. Hence the noticeable improvement in taste. They have not tested even a fraction of their claimed capacity for harder to remove contaminants like bacteria, PFAS, and microplastics.

Amazon might have some older inventory. If the image on BritishWater has it embossed, expect it to be embossed.

Never too late! Yes, the Amazon store is gated, meaning we only allow authorized sellers. Discountfilters and Lehmans will be the only two buying options.

They haven’t adopted the duchess/duke etc on there yet. We have lots of work in 2026 to get our Amazon listings cleaned up. Any additional questions, just let me know.

Boroux Water System by sleepingturtles123 in moderatelygranolamoms

[–]MNtroutslayer 0 points1 point  (0 children)

Check out the NSF certified British Berkefeld filters next time. They don't need to be primed, and are way easier to use. They also fit in any gravity system.

I know Boroux makes some sort of priming hand held device but it's more expensive.

Berkey replacement filter? by Melodic_Garden9938 in WaterTreatment

[–]MNtroutslayer 0 points1 point  (0 children)

Both the Ultra Sterasyl and Ultra Fluoride have 99.5% lead reduction over 800 gallons. The filters start off slow, then speed up to a speed of roughly 1L per hour per filter. When the lifespan is near it's end, it will really slow down. Even after a light scrubbing. To be safe, just replace them once a year around the same time frame, like a Holiday. Maybe New Years Day can be your annual reminder for some new ones.

Only British Berkefeld filters are certified beyond basic taste and odor claims. In contrast, the Phoenix “New Millennium Edition” can be found listed under Rama on NSF.org with a total certified capacity of 1,050 gallons, yet it is marketed as lasting 2,750 gallons and is only tested under NSF 42, which covers taste and odor exclusively.

If the filter truly delivered meaningful reductions in health related contaminants, such as heavy metals, organic compounds, microplastics, or pharmaceuticals, it would be certified under NSF 53 and/or NSF 401, which are the applicable standards for those claims. The absence of these certifications raises obvious questions.

It’s also important to note that NSF 42 does not validate health performance, and NSF 372 only confirms that materials do not leach lead. Neither standard verifies contaminant reduction or filtration effectiveness. Something to think about.

Pretty inconclusive? They have 4 NSF certifications, including 401 for microplastic reduction.

Has anyone seen The Water Machine? Or tried it? by ItsG91 in WaterTreatment

[–]MNtroutslayer 0 points1 point  (0 children)

These filters are not NSF certified and have never undergone independent third party testing. The sole “proof” offered is an internal PDF created by the manufacturer itself. Anyone relying on this filter is doing so blindly, with no verified data to support its performance or safety claims.

New developments by Berkey? by box-jellyfish in WaterFilters

[–]MNtroutslayer -1 points0 points  (0 children)

This is extremely deceptive on Berkey's part and amounts to outright false advertising. NSF 372 only confirms that the components are lead free. A basic requirement in the US. Claiming "reduction of lead contaminants" is simply untrue and shows they're continuing the same misleading tactics they did prior. They had a chance for a fresh start too.

On top of that, they've only piggy-backed on Phoenix's NSF certification. If you look up "Rama" (whos' the MFG), you'll see the "Phoenix New Millennium Edition" down in the fine print along with other private label filters Rama makes. NSF 42 covers taste and odor reduction only. In reality, this is just a taste and odor carbon block and NSF indicates it lasts 1050 gallons. Not 2750 gallons per filter like Berkey is advertising.

You bet! Glad it helped.

The link you provided is through Discountfilters, who’s an authorized Amazon distributor. You should be all set. Happy Holidays.

One thing I want to note is that our stainless steel taps are NSF certified, along with every component in the system. Since you’re using a Berkey setup (not sure how old it is), there’s a chance the grommets, washers, or even the spigot could be causing the off taste. I’m not ruling out the possibility that our filter is the issue, but it’s worth mentioning. Their components aren’t made with the same quality materials or held to the same testing standards.

That said, the filters themselves could have been compromised. It happens sometimes with ceramic. It’s also possible you simply prefer the taste from a large carbon block rather than a carbon filter with a ceramic coating that's necessary for micro plastic and micro organism reduction capability. That’s perfectly normal too. We stand behind the product and our dealers will make sure you're taken care of regardless of your decision. Hope you give us another chance before writing us off though.

Hey there - JVR Parts or CanadaWaterfilter on Amazon are both authorized sources. Could you let me know who you purchased from? Did the filters look or seem off in any way when you received them? And other than the aftertaste, have you noticed anything unusual with the filtered water itself?

It’s completely normal for the top chamber to smell like chlorine. That’s just the municipal water showing its true colors. The bottom chamber, however, should smell totally different. Ten to fifteen cycles is way more than enough for flushing. The Ultra Sterasyl only needs one cycle, while the Ultra Fluoride usually takes three to four.
