Nesh. They r&d their own system, more expensive but more longlasting than those China oem like filken and intact water

I ended up with intact because I don't think nesh is not worth it even its longer lasting (almost triple the price) . If intact can last 5 years also good enough then there is always new tech

Not sure about coway but cuckoo one requires them to come and service. Coway or cuckoo always look at profit from servicing so I rather not
