Works as advertised, way to save money
I bought this to replace Zero Water pitcher water filter, which were very expensive especially for water quality in California as I get to replace the filter so quickly. So far so good, I followed instructions and got the system running at 30 TDS level though (I guess because of California water was heavily treated). Let's see if it will work as promise-1 filter per year.Updated: after adding more water the TDS level kept rising to 45, 60 now 95 this is so unstable and I found a note stating that maybe because of water source and/or the residue of water mixing the reservoir but if it keep rising I would doubt the effective of this water filter system
Thank you for your feedback

5.0 out of 5 stars The best on counter osmosis
Reviewed in the United States on November 2, 2023
The machine has a good size, super easy to set up and the quality is excellent. The filter is last about a year. We have been using this machine for about 4 months. There is no problem at all. It is good for apartment that not allowed any under-counter water filter. There is four modes to dispense water 4oz, 8oz, 16oz and 32oz. The touch button is nice and sensitive. The water tase great. You can see from the video that it decreases the bmp from 100bmp(tap water) to 3bmp(after filtered). Plus the smell of the chlorine that comes with tap water is gone.

Only some downside are the water tank is kind small(L1 means refill water) and it doesn’t able to dispense 24oz (mostly water bottles we have on that size so you need to do 16oz and 8oz) lastly is about the price is slightly expensive. However, it will be worth it for the long run.
