Reverse Osmosis Water Filter Countertop, 6 Stage Ro Water Filtration System with Remineralization Glass Pitcher, 4:1 Pure to Drain, TDS Real-Time Displaying, 4L Capacity Tank for Home Office

it arrived fast and well packaged. Haven't tried yet.

Overall, a countertop split-type RO water purifier may not be the most convenient solution for daily long-term use. However, as a temporary or quick-fix solution, it can be considered nearly perfect. The build quality of the device feels solid, and the water tastes clean and fresh. The machine shows an output TDS reading of around 10, which I believe is quite accurate.For a household with relatively low water consumption, this product is definitely worth recommending. Compared to continuously buying bottled water, the payback period is quite short, making it a cost-effective choice.

This countertop RO system is rated for a maximum input TDS of 500 PPM. This means that it works best on municipal tap water, which usually has a TDS below 500 PPM, or for water from a relatively clean filtered source such as a well or a freshwater lake, which is often around 300 PPM or less.It doesn't appear to have a UV sterilization stage, so it seems that the system is aimed primarily at removing inorganic solutes rather than pathogens. The product information does not specifically mention pathogens, although they are physically much larger than the tiny solutes it does filter. It claims to filter down to a size of 0.0001μm, which is about five thousand times smaller than a common bacterium.Purifying sea water, which usually has a TDS around 35,000 PPM, would not be an option with this system.Replacement filters seem to be fairly expensive, although they do appear to last a long time. For anyone with drinking water contaminated by industrial activity or that is supplied by a marginal well, this is likely a very reasonable expense.This is an absolutely fantastic idea for a camper, where you are likely to have the electricity to operate the machine, but where you are unlikely to have immediate access to bottled water. I regularly take the RV to any number of locations where I can find clean water that I would not dare to drink unfiltered.I can't find any information about the average power consumption when the system is in use, which is one of the most important considerations for a camper or anyone living off grid. RO systems have become much more energy efficient recently, but even an efficient machine can be a strain when you're mobile or depending on solar or wind. Only time will tell if the system is viable in those circumstances.It appears that the system may be rated for a water output of 100 GPD maximum, which is tiny for an RO system, but more than ample for most drinking water needs. A lower maximum water output rating may imply lower power consumption on average, which would be ideal.In testing at home, the system is working well, but it's hard to be sure since our municipal drinking water is excellent. We'll see how it fares on the road.

I usually get reverse osmosis systems that connect directly to the tap, then you can just flip a valve to redirect the tap water to go through the filer. Those filters are cheaper and easier to use. Unfortunately I moved into a fancy apartment with fixtures that do not have the flexibility to allow the types of connections I had been using for more then 20 years on those other types of RO filters.So, I purchased this filter to accommodate those new tap fixtures. I've had this filter system for about 7 months now. While this filter works as advertised (so far), it is a bit more labour intensive to operate. I tried filling the container without disconnecting it from the system, but then it starts to beep a lot. The system requires that the container that holds the water bee removed prior to filling, and every time you reconnect the water container to the system, it immediately starts priming the pump and flushing the filters. You must be extremely careful not to miss the connection, or the pump could blow-out (if it starts pumping air during the priming process). The connection for the water container is at the back and there are two hooks that must align with the container while inserting it back into its connection, it's a little tricky, and if you miss, you could easily blow-out the pump that forces the water through the two filters.I tried to just refill the container without removing it, but then the system starts to beep and insists on removing the container, then I rinse it out, refill it, and reinsert it into the connection at the back of the device.The system is working, but it is more work then I am accustomed to doing for a water filtration system and I miss my old model, because all I had to do was flip a switch/valve attached to the tap.I read other reviews from people with this device, some complaining of loud banging noises when they attempted to reattach the water container, then the device no longer works. I would imagine that this is what happens if the container is not reattached with a solid connection, the pump would immediately start sucking air while attempting to prime and flush the filters. If the pump is damaged, I would imagine the device would no longer work.I cringe everytime I reconnect the water container because if I don't line it up correctly and it starts to prime the pump, this system would probably no longer work if the pump blows-out. They should allow you to take your time to reconnect the container and then once you verify the connection, have you push a button to start the priming when you are ready, not just right away when it senses the connection.In all fairness, the device is still delivering filtered water after 7 months, but it is making me work for it. I have not drunk unfiltered tap water for about 25 years, it's worth the effort, but it seems like a lot of work compared to other filters types out there.

The water quality is great. However, and due to constant flushing, you will need to discard at least one third to one quarter of the reservoir every time. Also, shortly after it starts dispensing, the water quality would not be as good for about half a minute. That part, I do not drink either. I hate wasting water so I use both portions that need to be discarded to water my plants. All in all, good value for the price

Ótimo produto, recomendo.

Slow, only filters small amount of water at once. Good for one person.

Pros: There's a noticeable difference in taste of the water I put through it. It's doing it's job and at a pretty good price. The cons: As others have stated there's a red light that comes on to indicate about the water you put in to be filtered is way too high in pollutants for it to be very effective and that you should really be using different water. Anything over 500 supposedly triggers it. It and if you replace it with better water for it to filter in theory it does a better job. Makes sense. Except the light comes on regardless of what water you put in there to be filter. I've tried bottled water, I've tried water that's been through reverse osmosis already. It doesn't matter it tells you the particles are over 500 no matter what. And when it filters down it's supposed to get it as low as possible. There is such wild fluctuation in the number that it's really impossible to know. Sometimes it will read a very low number in the 20s and 30 seconds later it jumps to several hundred. 300 it less is what's recommended to be safe to drink. I bought independent testers and it seems to be working pretty well but the numbers do not match up to what's on the reader. Also the instructions for initial usage are a little convoluted. There's a whole flushing process that has to take place. That brings me to another con, the process is very slow. Pretty much have to turn it on and walk away for 8 minutes get 40 oz of drinkable water. The tank will hold roughly 120 oz that it will filter then it stops even though there's more water in there until you empty out that water and fill it up again. Also the indicator for the water levels doesn't reset correctly unless you fully fill it up again. The tank is not a very large capacity. There's just me in the house and I'll go through multiple tanks in a day. So yes it does work even though it's nearly impossible to know how well just using the machine itself and it does it for a good price but just know there's some quirks about it that are not fixable.

I over flowed the pitcher onceDue to my mistake not the machine. Didn't know someone had already pushed the button .But everyone in the family,husband,daughter and grandson all like it.the water is fresh tasting and we all enjoy the water. Thank you.

First time I bought over the counter RO water filter system. I like the glass water pitcher.Using Zero water filter for several years until online testing shows this filter will add more microplastics to the filtered water.I have been using SLEVOO filter for about 2 weeks, so far so good. No more bleach smell, water taste is good. Hopefully the system will last long time.The customer service is excellent ! I left customer service a message for a small part, thinking that I need wait for at least 24 hours. But less than 5 minuted my phone ran, it was Mr. Joe from SLEVOO technical support department . He assured me that customer service department will contact me and send me the missing small part . The following 2 or 3 days I received his messages to update the process.Thank you Mr. JOE! Thanks SLEVOO for the nice product!Mary C

Amazing...this system delivers. Input water from my community is consistently in the 300-400 PPM range. the output water is consistently in the 3-5 PPM range, and tastes great. Simple, and easy to use.
