Customer Reviews
Very nice product for home drinking water purposes, it is a 400GPD (gallons per day) tankless reverse osmosis filtration system. Installation is very easy with no tools required & since it is tankless, the filter system hooks up to the water line & its size doesn’t take up much space, it even comes with a fast flowing water faucet & filter that lasts up to 1 year before needing to be replaced. The water processes from this filtration system is so crisp & refreshing to drink, the price is well worth it for this under sink water filter.
Was easy enough to install, directions were clear. It does have a low hum when running but nothing to obvious or problematic. Fit under our sink easily and took about 40 min to install.
Exactly what we were looking for as an added cleaning agent for our home! We are so pleased!
I like the concept and I hope this holds up to my expectations over time. I have had an RO system in the past which required filter changes about every three months. Back then, it was pretty expensive. This unit claims to go at least a year, depending on your water supply, I guess that's sort of a cop out on their end, but I don't think any of us can get away from that particular issue. There is some legitimacy to that claim so I plan to come back in a year or so to update this review if I am unpleased. I do not care for false advertisement and I'm not saying that these folks have done that. I am just the sort of person that will actually take the time a year from now to follow up if necessary.Now, it is an easy device to install if you already have a hole for the faucet. It will require some mounting work, but it's pretty negligible considering what it is. It's not very heavy, it's compact for what it does and access to the filter cartridges is pretty easy:-)I expect to be rejuvenated within about six hours of initially consuming the water from this. Just kidding :-)I do expect my water to taste better for many months to come before having to change the aforementioned filters. :-)The instructions for installation are pretty easy to understand so I recommend picking one of these babies up! :-) LOLI am happy with my order and I hope this was helpful. ✔️ Thanks!
