None of these are deal-breakers, but this system is notably:

- A little loud/vibrates while in use
- 1:1 clean to dirty water usage. For $80 more, you can get 2:1
- 400 GPD is really slow. Again, for $80 more you get 600 GPD. Neither are particularly fast though.

Here's another option at $279: https://www.amazon.com/Waterdrop-...08746G2XX/

I have it, you need an electrical connection (120v) but is way better than needed to wait for water. 3 years with mine and so far very good.

I have 600 GPD and have installed a few of them. 600 GPD is right speed. I would not go with 400, too slow.

The good news is that they have sales all the time.

Looks like they are making way for the newer G3 series. Not sure if it might go lower during prime day!

Not really, but the replacement filters are $90 each. Almost cheaper to buy a spare to use just the filters.

Seven stage? I see an RO and a carbon filter.
What is the cost of these proprietary filters compared to a tank type system?

I think I could, but that is because I already have a plug-in below my sink and I have replaced a bit of plumbing skills I assume you need to drain. That being said I haven't looked into this model's install instructions yet.


edit ya looks pretty easy..did not watch with audio https://m.youtube.com/watch?v=HJP-StdSYDM


Hints. the water pipe will have water in it and you need a bowl. 2 the water pipe will not come Apart that easy, you will need 2 wrenches.


edit you may lose an established built in. sink thing, we had a soap dispenser and I replaced it with a spray hose, but this would replace that.

First 20sec the TDS is over 100. After that it is around 50ish. The tank type is much lower, but this is faster if you need a lot at once.

This is a great deal. I have used it for last 2 years. Working out great. Only thing is the first glass of water is a little bit hard... So I usually fill a water container when I turn it on and it's really good that way. I have replaced the cartridges a couple of times now and everything is easy. I put an extra pipe for the wastewater to my garden so that I don't waste the waste water.

Sorry for my naive question. Is this only for drinking water? If so, isn't the water dispenser on the refrigerator enough? I'd like to install this device on kitchen sink to get purified water for cooking, but this one doesn't seem to have a spray head, so not a good idea?

Thanks for the suggestion. Haven't done any research yet...is there a water filter system that is considered the best, regardless of cost?
