  1. Morning Star

    Excellent solution for rentersI’m renting in an area that apparently has a water infrastructure that has been failing without meaningful repair for 80 years. The water smelled like a public swimming pool in summer and was making any food cooked with it taste awful. It was also causing GI problems. As a renter, I needed something that wouldn’t require a plumber to install or require me to damage cabinets or counters through drilling for under sink set up. I’m also not rolling in cash, hence why I rent, so this was a perfect solution that checked all the boxes. We’ve been using this for several months and water quality is way better. Since it’s RO, I just bought some remineralization drops here on Amazon and we’re good to go!

    overall a good reverse osmosis systemFor a tankless system and at the cost point, this unit gets the job done. My water tastes quite good coming from this unit. It is not too big in size. one item to note is since this has no tank, it takes 5-10 seconds for water to come out depending on your home’s water pressure. I also had to use a thicker plumber’s tape when attaching the spigot to my sink, to stop it from leaking there. Not a big deal, just a slight annoyance. The suction cup that is used for the waste water line is too small. Mine came off every time, resulting in water go everywhere. Despite these downsides, this saves from me having to drill into my countertop. I’m very glad i bought this and wish i done it sooner. Their support people are nice and answered my questions before i bought it.

    Great Versatile On-The-Go Portable R/O System !I am using this to fill up the water tanks on my boat when i hook up to municipal water at marinas (with a 3/4” hose adapter) and it works great. It takes a few hours to fill my 30 gal main tank but well worth it to have r/o water! This is a great versatile system. If I am in a hurry I can just fill the tank with unfiltered tap water and hook this r/o system up directly to the galley faucet. Be aware that waste/filtered water ratio may be a consideration when filtering at the faucet instead of prior to filling your tank in rv/boat: as half the water will be used to carry away brine in this configuration. Same with any/ most r/o systems. This is the most versatile on-the-go portable system option i could find and it’s great!

    I like itInstalled it a month ago and it works great in my apartment. I live in a rental room and share a kitchen with another roommate. We are not pitcher fans since it takes forever to wait. And we are not allowed to drill any holes in the apt. So the typical ro system is not an option. We’ve been doing researches trying to find one like this. Although it ends up a little bigger than it looks, I had no trouble install it at all and happily the landlord won’t find any weird holes in his house when we check out:D Very satisfied!

    Great productI have been researching for a long time to find the water filtration system that can fit our kitchen. We do taste something wired in our tap water but do not have enough space under sink. The traditional RO system is too big for us in this case. And then we came by this product which has the perfect size and also contains RO system.The product came in great package. It helps reduce the chlorine and tds in my water a lot and improves the taste. The whole installation process is quick and easy. It also helps save a lot of space in my kitchen. We are very happy with this purchase.

    Best tasting water I’ve ever had!I was worried about the installation process before it arrived, but it turned out to be pretty easy. The package includes everything you need, a wrench, tape, and extra fittings! Just followed the instructions in the manual and got it installed within half an hour. The product is also nice looking and fits well on my kitchen counter.Now my tap water tastes great!! It’s completely tasteless(quite refreshing too!) I tested the tds number of my tap water and filtered water – it dropped from 78 to 4! My husband is very happy with the purchase. Now we have clean, pure, and refreshing water to drink for our family. Thank you ispring

    Seems pretty high qualityDecided on this filter after looking around at similar options and having used their products before and I believe I made a good choice. This model seems pretty well built which is always a good sign compared to some of the plastic junk out there from other companies. I used to buy bottle water for everything and know I know I will save a lot of money because of this. And my cat and fishes will have fresh clean water to enjoy! Overall I am happy with it!
