The design looks modern and fits nicely in my space. I am happy with how it performs. The machine is expansive, but from what I researed, this kind of product is mainly use in manufactories. And this one is narrow the technology into home applicant. It does remind me of dehumidifier plus filtration system.
Really solid system, works smoothly and water feels clean. I just think the best of it is the convience. We have kids party and we bring this to our public room. It doesnt need electity is actully my first choice. I actually come across another product m8-2. iit also works without electricty. but it needs a bit of installation. so i choice this one instead. But I am still considering wether get a undersink in my kids bathroom.

Good value for family use and easy to operate.
Puflow C9 Pro Hydrogen-Rich RO Countertop Water Purifier Cold to Hot Water Dispenser UV
Overall this is exactly the kind of under sink filter I was looking for. The size is great, it fits easily under my sink without taking up much space, and for the price I think it is a really good option. The only issue I ran into was with my cold water shut off valve. The threaded connection on my valve was a little shorter, while the connector that comes with this filter is fairly deep. Even after tightening it all the way down, it still had a small leak because it could not fully seal. Luckily I already had a 1/4 inch sealing gasket at home, so I used my own part and the leak was gone right away. If I did not already have that gasket, I probably would have had to stop the installation until I found one. I think it would be nice if the kit included an extra sealing washer or a slightly different connector to fit more types of valves. The product does come with a no thread tape fitting, but I found I had to wrap quite a few layers of thread tape to get a proper seal. Since I had a 1/4 inch PPR silicone sealing gasket in my toolbox, I ended up using that instead and it fit perfectly with no more leaks. Once everything was installed, though, I have been really happy with it. It is compact, easy to hide under the sink, and performs exactly the way I wanted. For someone looking for a small under sink filter instead of a bulky system, this has been a great fit.
Very happy with the purchase. Would recommend it. It is so easy even for replacement filter.The best part for me is the replacement takes longer than I expected. So I don't need to worry about keep hanging the filter and use it in a safety mindset.

We live in a small space so this works perfect because it does not need electriciity and I do not need to always leave it on my counter. If I dont need it. I can put it back and store it. Because we rent, and the faucet landord has doesnt let us change. So we are not able to upgrade to the filter faucet. Alternatively, this one is perfect for our small space and also when we need clean water.
Big Flow2 Gravity Water Filter System Stainless Steel Countertop 8.5L
Very pleased so far. We were considering a whole house filtration system but decided to try this first. For drinking and cooking water it has been a great solution and the output is more than enough for our household.
I live in an apartment by myself and have been dealing with some skin issues, so I started looking into getting a water filter. I talked with my landlord first about replacing the faucet, but they said no because it would affect the apartment and probably my deposit. Since I rent, I really did not want to risk that. At first I looked at regular under sink systems, but most of them are pretty big and really designed for a whole family. I did not need something that large. I spent quite a while researching until I came across this one. Honestly, I was surprised by the size. Compared to most under sink filters, especially the electric RO ones, this one is much more compact. It is not a reverse osmosis system, it is a pp cotton+active carbon+UF filter, but for my needs it is more than enough. Because of my skin issue, I even asked my doctor, and they said filtering down to 0.01 micron is perfectly suitable for what I was looking for. Another reason I picked this one is because the installation is much easier than most under sink systems. It does not require drilling a hole for a separate faucet. You only connect the inlet and outlet, which made it much more renter friendly. I did struggle a little with one of the connectors because it needed a bit more strength than I expected, and I did not have a wrench at home. the rest was easy. Since I cannot drill into the cabinet wall, I just placed the unit inside the cabinet instead. It is still compact enough that I have plenty of room left for my cleaning supplies and other kitchen items. Overall it has been exactly what I was looking for. simple and renter friendly, and it fits my needs really well without taking over the whole cabinet. I am going to get another one for my kitchen as well.
So were a family of 6 me, my wife, and 4 kids. We dont have one of those big fridges with ice makers, and honestly our kitchen just doesnt have the space for it. But my wife and kids all love iced drinks. I actually got this for my wife as a Valentine gift, kind of like a small upgrade for the house. She used to go out and get Dunkin all the time (and always says shes gaining weight from it lol), so I thought this would help. The nice thing is this machine gives you really cold water without needing to add ice, which is exactly what we needed. Yeah its a bit pricy, but for us I think its a good upgrade overall.

Big Flow2 Gravity Water Filter System Stainless Steel Countertop 8.5L
Very satisfied. Clean water, strong flow, and no issues so far. The best part is no installation. I had one undersink before, it is not hard to insstall, since we dont have our own space. It was hard for us to move to a new apartment and install each time when we move.So we sold it second hand. I love the feeling of free hand in this case. This is so high tech and no inslallation at all.
Puflow C9 Pro Hydrogen-Rich RO Countertop Water Purifier Cold to Hot Water Dispenser UV
I was thinking about getting a full under sink system but were renting, so went with this instead. Honestly it works pretty good for what it is.
Really impressed with this RO system. We have pretty hard water where I live and the difference was noticeable right away. My wife drinks more water now and even the coffee tastes better.And the instruction book makes it easy for me to install by myself. These small parts are all packaged very easily for me to find each.
Very happy with this system. It took me about half an hour to install and having a wrench nearby definitely helped with tightening the fittings. If you dont have a wrench to tight the connected parts. It will take much longer installation.
I started my RV life around the middle of last year. I am not a very technical person, so I knew living in an RV would come with some challenges, especially when something needs fixing. One thing I quickly noticed was the water. RV water can be pretty hard, and when I used it for cooking, it always had this weird taste.I asked around at the RV camp and a lot of people recommended getting a faucet water filter. I looked at a few options and chose this one because it is not plastic and feels more durable, which is exactly what I needed. I move around a lot, so I did not want something that might break easily. So far it has been a really good fit for me. The water tastes better, and I like that I can switch between normal RV water and filtered water easily. It also means I do not have to use up the filter too fast.

Got this for my office love it. I set a tea station in my office
I originally bought it because of the price it fit my budget and had everything I wanted in a countertop unit. But after using it, it honestly made my life so much easier. I live in New York, and even after boiling, the tap water still tasted a bit off. Now I just get clean hot water instantly no more waiting for a kettle.
Helps but requires regular filter changes in my home.
I got this about a month ago, and my neighbor already borrowed it twice. Once was for her kids birthday party in the backyard, and another time for a different party she had. I do not even remember what that one was for, but she kept saying how useful it is. I sent her the link already, just hoping she will get her own soon instead of always borrowing mine haha. She mentioned it works really well when there are a lot of kids around. Since it does not need electricity, it is easy to move around and you can place it anywhere. With electric ones, it is just not enough for everyone at once. This one is portable, simple, and actually gives more flexibility when setting up for events or decorating the space. Honestly just really convenient, just hope I can have mine back.
I noticed the water is much cleaner than tap water no more weird particles floating around.
My kitchen is big, but it has limit plugs, so I try out this one. I am very satisfied with it.

I installed this in my bathroom and I feel like my skin is less itchy when I wash my face. At first I thought it was an allergy, so I even took ZYRTEC but it did not really help. I also changed all my skincare products and still had this small itch on my face. Not super serious but it was annoying every day, especially when I was working. My dermatologist suggested maybe try changing the water and using a filtered faucet to see if that makes a difference. So I decided to give this a try. At first I was not expecting too much honestly, but after using it for a bit I realized it actually helped. My face is not as itchy as before, and my skincare feels like it absorbs smoother now. I guess the water was not as clean as I thought.

Decent filter. Because our water is pretty rough I feel like it takes more maintenance on my end, but the water quality does improve.
