This surprised me, what is the value of the blockchain water purifier? Is such a water purifier a producer of pure water? Maybe this is the flow of water to generate profits? Haha, this is a really interesting point!

LOL I was thinking the exact same thing. Although this is very fascinating. It always seems like chinese projects are making such huge strides for blockchain and iot. this is what the article says:

"Depending on how long and how frequently consumers use the product, they will earn a blockchain token called PWMC, which they can then redeem for replacement filters, or to purchase other goods.

This rewards system will provide an incentive for usage thats lacking in other IoT products, Xiao said, while at the same time make blockchain relatable for the average person who doesnt spend all day trading cryptocurrency."

So I guess it's based on how often you use the filter and then you can redeem your tokens earned for new filters....very interesting
