Ecoviva Mate 4 Countertop Reverse Osmosis Water Filter System with UV, BPA Free, 7-Stage Filter, Pure to Drain 3:1, Instant-Hot, Indoor No Installation, Desktop Water Purifier MATE4 (Navy Blue)

I have owned several brands of countertop Reverse Osmosis machines over the last few years, but none has been as easy to use as this one. It was easy to bring online, meaning flushing the system 6-8 times before its first time use. Assembly was as straightforward as removing the packing tape, filling the reservoir with water, and plugging it in. It dispenses three different preset volumes of great tasting water. It also quickly dispenses 4 different temperatures of water to include room temperature, 115 degrees, 185 degrees, and 212 degrees. That functionality of providing different water temperatures is perfect for baby formula, coffee, tea, or oatmeal. The 6-stage filter with the UV light provide 7 stages of water purification. I also love that it is designed with a built In TDS Meter that is easy to read. Also with a 3:1 pure-to-drain ratio, it’s 1200% more efficient than traditional RO systems. There is only one filter to change and that can be accomplished in seconds and even provides a tool to use for removing and replacing the filter. It also indicates when the filter is reaching the end of its life which gives you a chance to order a new filter that is available on Amazon. The functionality, price point, filter availability, temperatures dispensed, pure to drain ratio, and great tasting water make this the best RO machine I have owned. I highly recommend it.

This is a great water filter system BUT when the filter is ready for replacement, you may as well count your losses. It is a lot of money up front for one year of service. The replacement filters are unavailable and no other options exist. The company is not helpful. They just advise to keep using it while following the directions that you already are following.

THIS IS A GREAT PRODUCT! First of all, its a product you can trust. It's one of the only reverse osmosis machines to come with third party testing results and it also has some of the best filter qualities I found. Value for money, you wont beat this anywhere else. I spent a lot of time researching and this was the cheapest, lab verified reverse osmosis machine I could find. When I first bought it, I stuck my hand in the already filled water tank to remove a sticker in it. My hands were definitely not clean and I chose to drink the hand water to test if the filtration removes taste. I did not taste hand water. Its easy to set up. The controls can take a second to understand but are also pretty intuitive once you figure them out. It has multiple heat settings and fill settings. My biggest complaint is how long it takes to fill up water. It takes long enough to fill up a glass that I often wander off to do another task while waiting. On the flip side, its very quick to go from a newly filled tank -> outputting water. The heated water function is also pretty quick. My second biggest complaint is it outputs room temp water at coldest. There is no setting for chilled water.

I just had this Ecoviva MATE4 Reverse Osmosis Countertop unit ordered from Amazon and received this the very next day. Very impressed with the great packaging also, as this was double boxed for best protection. We have had several Reverse Osmosis systems in the past but this one, right out of the box, is getting only 2 tds! Our water from the municipal water was 185 tds, now it is only 2 tds!! The water quality is perfect, with no taste at all, just pure water! Also this runs so quiet you can barely hear the reverse osmosis running. My wife and our son also love this also, as the hot water option has instant hot water. This unit is perfect for a home, motorhome, or any place you need to have pure water. This is very compact and takes very little space. Highly recommend this Ecoviva Mate4 UV Countertop Reverse Osmosis to everyone! You will love this!! This company makes the best quality water technology for sure. This is the best value for the money, and best ease of use. Very glad we purchased this.

I didn't write a review right away as I wanted to test out the system first. It does take a few times (6-8) to get the filter primed (feeling like I'm wasting water to do so, but that's how the system instructions states). After that process is completed it's easy to operate. I like the hot water feature (I usually heat up a cup of water in the microwave), but now I don't have to. It also has a locking feature so that a child (or adult) doesn't accidently burn themselves. I can tell the difference between my tap water and the filtered water. I prefer the filtered water now. The other reason for purchasing this item was that I have a hydroponics plant grower and it calls for using Reverse Osmosis water so it doesn't clog up the small pump (which hard water will do). Overall, I'm very satisfied with the product for my first Reverse Osmosis machine.

The machine works perfectly, but unfortunately, Ecoviva never seems to have replacement filters in stock here on Amazon. This is the second machine I’ve purchased from the brand. I bought this one because I couldn’t find replacement filters for my previous machine, so I decided to upgrade instead. Now, a year later, I’m in exactly the same situation: I need to replace the filter for this machine, but the replacement filters are never available. It’s frustrating to have to consider replacing an otherwise perfectly working machine simply because replacement filters aren’t available. If I have to buy another machine because I can’t get replacement filters, I’ll probably choose a different brand this time.

The Eco Viva reverse osmosis was easy to set up but some of the instructions are not to clear, and I had to resort to youtube videos to learn how to use the machine. When I first set it up I heard the machine makes some noise, but it didn’t want to go to the ready position. I realized that I did not push the water bin down enough and lock into place. It took me approximately six rounds to clear the water. After that, the water came out very clear, and tasted better than bottled water. The water flow is OK. But it could be better. Also, one feature. I don’t like is that the writing on the touch pad is small and not so visible. The Manufacturer should’ve make the fonts bigger and bolder to read. The following morning I woke up the machine went on E2 mode which is Maintenance mode and I cannot get it to work. The push buttons were not responsive and I had to unplug the machine and plug it back again to make it work. The heating element works fine. I made coffee on my French press. Overall, I would give it five star But because of the trouble I went through to get it to work, I feel it only deserves four stars.

Me gusta muchísimo, antes compraba paquete de botellas de plástico y con esto no tuve que hacerlo mas, además la opción de tener agua caliente es perfecta para invierno.
