Debunking ClearlyFiltered?

Has anyone really looked into this company or these claims?

They make a lot of claims on their website but I've yet to find an actual technical manual or patent description of their filter, which is very troubling. They describe vaguely in pseudo-scientific language how it works, but it all seems very sales-pitchy to me. And again no papers, studies or patent info about what the technology actually is.

"Affinity Filtration uses a unique dual-technology approach "

"Unique Physical Structure" (sounds like carbon filter?)

As contaminants move through a filter built with Affinity Filtration Technology, they have to travel through many twists and turns, as opposed to traveling in a straight line. This provides more time for the water to contact the filter, which gives the contaminant magnets more time to do their work. The longer the filtration time, the more thorough the contaminant protection. When it comes to water filtration, slow is a good thing.

"Contaminant Magnet" (sounds like... a carbon filter still?)

You can think of Affinity Filtration as a combination of tiny, powerful magnets that recognize the ionic signatures of very specific types of harmful and dangerous contaminants. When a contaminant is detected, one of the magnets draws it out of the water and binds to it with a powerful and lasting bond. This keeps the contaminant locked in the filter and out of your water for good.

But then they seem to contrast their filter with carbon filters?

"Clearly Filtered® with Affinity® Filtration Technology gives you the power to remove up to 99.9% of the most common radioactive elements from your tap water, giving you peace of mind that comes from knowing your drinking water is finally clean and safe. Basic water filters that rely on simple carbon or charcoal are only effective at removing unpleasant odors and taste. These filters are not capable of stopping radiation and instead allow it to pass right through the filter into the water you're drinking. More sophisticated technology like Clearly Filtered is required to provide this type of contaminant removal."

The referral link industry and lots of "green" blogs that paid on link referrals have been promoting this filter for years with very little science-based analysis and lots of hype, its all very troubling to me.

Edit: I did find from one source says their filter is 1: "A woven mesh screen" 2: Granulated Coconut Carbon and 3: Composite Shell of seven proprietary filtration materials. No patents though? Just a secret formula? I'd be less concerned if they actually received any NSF certifications, while they do have certifications from WQA (which is a trade association, not so much an independent lab) - those certs only indicate they filter PFOS and PFOA.

Confusingly they also say they use an EPA-approved laboratory (not WQA?) that use NSF standards, but not the NSF itself? Hugely suspicious about that. They also don't name the laboratory

Only tested for PFOA and PFAS

Which EPA approved lab?
