5-Stage Portable Reverse Osmosis Water Purifier: Efficient & Eco-Friendly

So, me and my girl decided to give this water purifier a whirl right around Memorial Day weekend. It showed up all nicely packed and setting it up was pretty straightforward. The instructions? Clear as day, super easy to follow. We've got well water that's been softened, but honestly, it wasn't something you'd want to drink straight up—had a TDS reading of 490. But after running the water through the new filter a bunch of times like the booklet said, the TDS on the purifier's readout started showing mostly between 10-40, and then it kind of settled in the sweet spot of 15-25 after a bit more filtering. That's smack dab in the efficiency range they promised, so thumbs up there. Yeah, you get a bit of waste water, but honestly, it wasn't as much as I was bracing for. This thing doesn't drag its feet and it's quiet, too. Really simple to use, doesn't hog space, and you can pause the filtering whenever. We've got a bunch of Mason jars—32 and 64 ounces—that we fill up and stash in the fridge or leave out. Even the big 64-ouncer fits right where the carafe goes. I was digging the taste right from the get-go, but my girlfriend wanted a bit more oomph to it. We found that dropping like 4-5 drops of this concentrated mineral stuff into a full carafe (we're talking 40 ounces) did the trick for her. Oh, and our older cat? She's all about it now, drinks it more than the tap water. Pros: It's a solid piece of kit, cranks out clean water like nobody's business, and it's exactly as they describe it. Cons: Can't say there's much. Just heads up, it might drip a few drops of water here and there during the backflush thing, and when you pull the tank off to fill it up, might get a bit of water on the ledge. But it's minor stuff, nothing a little towel can't handle. I'm really liking that it's just one filter in this bad boy. Hoping it'll last the 9-12 months they say it will. It's perfect for just the two of us, especially since we're both retired. Pretty sturdy build and the blue color's a hit.

Been using this for three months and it's lived up to my expectations. A UV light and a solution for the waste water going back into the source tank would be nice improvements. The TDS sensor doesn't track the initial flow, but the overall water quality is definitely improved.

Been using this thing for a few months now, ever since I spotted algae in my old filter pitcher—gross, right? Wasn't exactly thrilled about dropping a bunch of cash on a single device, but looking back, totally worth it. It's a bit pricier than getting a full-on reverse-osmosis system installed, but living in an apartment, I needed something portable, something that doesn't mess with the plumbing. The water tastes incredible, honestly the best I've had. My mom visited soon after I got it set up, and we couldn't stop talking about how good the water was. Plus, I feel way more confident about its cleanliness, no more algae worries for me. There's this tiny issue where water can splash out from the tank's little holes if I'm moving it around, but that's about it for complaints. It's just me and my cat here, and filling up once a day has been enough. Would definitely recommend it to anyone in a similar boat, worried about water quality. Seems like it's going to last a while, and I haven't even had to think about changing the filter yet. Just a heads up, it does make some noise occasionally, but it's a small price to pay for top-notch water.

Living in an apartment really limits your options for stuff like this, so I was on the lookout for something compact that I could easily move with. I've only had this for a few days, but so far, it's been a game changer. Picked it up in white, and it's got this sleek, modern vibe that's super easy to keep clean. Was a bit hesitant about the price tag, but it's proving its worth every day. The convenience of swapping out the filter just once a year is a huge plus, definitely beats running to the store for water bottles. Filling up the carafe takes no time at all, and the build feels really solid. Setup was a no-brainer with the instructions provided, and once you've got the filter flushed, it's pretty much plug-and-play. The water tastes fantastic, and it's cool that you can use it in place of distilled water for other needs too. My only nitpick is the plastic bin you fill up—it seems a bit off to focus on the health perks of the glass carafe but then have the water sitting in plastic beforehand. I get that glass might hike up the price and be more fragile, but it would make the whole health angle feel more consistent. Still, when you stack it up against the other countertop options out there, none of which offer a glass carafe or look this good, it's clear this one's a cut above the rest.

Now that we've had it for a couple of months, we're really happy with it. Yes, it requires a bit of maintenance, but it's so worth it. The water tastes great, and it's saved us a ton compared to water delivery services.

No more worries about water quality or lugging heavy bottles around. The filtered water tastes amazing and even improves the taste of coffee and tea.

Moved to NC and quickly realized the tap water wasn't cutting it. This system's been a game changer—clear water and the digital TDS readings offer peace of mind. No more bottled water for us, and it's coming camping, too.

At last, clean water! After diving deep into research, I'm thrilled we landed on this system. Hits all the marks we needed, at a price that doesn't make you wince. Did the math, and it's clear we're going to be saving money over the long run, making the switch from bottled water to this. And let me tell you, this filter is a champ—cleans tap water like you wouldn't believe, even knocks out fluoride. The water tastes fantastic, almost like distilled—super smooth and refreshing. Pumped that my family's now drinking water that's not just healthy but free from microplastics. Quality's solid, much appreciated. Just got it a couple of days ago, and so far, smooth sailing, no glitches or anything. As long as it keeps up like this, I'm all in.

Ideal for anyone with bad tap water who drinks a lot of water. It's lightweight yet feels sturdy. The carafe is well-made and the water taste is unmatched. Set up was easy, and it's efficient for both coffee lovers and those aiming to reduce plastic waste.

This unit's been a hit, especially for my special plants and improving our well water's taste. Filters water quickly, offering the next best thing to spring water.

It's both a functional and stylish addition to the countertop.

After a string of filter failures, this one was a breath of fresh air. The water quality and taste improvement was immediate. Even our cat prefers it. The LCD monitor for water quality is a nice bonus. I find the water left over after flushing useful for watering plants.

It's been amazing seeing the difference in water quality. No more plastic bottles for us. It whips up a full pitcher in just 5 minutes. The glass pitcher is sleek, though it feels like it could be fragile. Excited to try making flavored waters next.

Got this setup on our kitchen counter, and it's surprisingly compact. Found the perfect spot near the fridge where it's out of the way. It's been over 6 months now, and this machine's been nothing short of fantastic. It's quick to fill up a carafe, and it's been more than enough for our needs—me, my partner, plus our dog. For cooking, I still use tap water, but for everything else, it's all about this purified water. I keep a quart Mason jar of it in the fridge, refreshing it daily, just to have on hand. Given the reverse osmosis process, I reckon the water's slightly acidic, which is why I prefer storing it in glass. We also picked up some mineral drops and use them now and then. Sometimes for watering plants, like tomato seedlings, which seem to thrive on it. Or if I'm chugging more water than usual, say after a workout, I'll add a few drops. The filter's still showing two bars after 6 months of daily use, so it looks like it'll last as long as they say. Wouldn't want to go without it now. The size and performance have been just right for us.

Wanted to fall head over heels for this filter, and I'm not quite there. Water taste could be better, but adding a pinch of salt does the trick.

I'm all about this machine—looks sharp, top-notch quality, and the water tastes incredible.

Decided it was time to ditch the plastics.

Machine's been working like a charm, quiet and compact on my kitchen counter. The water tastes fantastic, and I sometimes add minerals for an extra kick. Setup was straightforward.

Having distilled water for years, this is a huge time saver and much less of a hassle. Simple to use and set up, giving two full carafes of pure water per tank. The TDS display during filtering is a nice touch, showing just how effective it is. Highly impressed and would definitely recommend.

The difference in water quality with this system is startling, making me question what I was drinking before. It's also super portable, ideal for renters or frequent movers. If you own a home, though, you might find an under-sink system more convenient, as they auto-refill.

After hunting for a suitable water filter for apartment living, this RO system hit the mark. It's been fantastic for the past 5 months. Water tastes great, but I do wish the tap water tank was a bit bigger and it had a drain hose option. Minor inconveniences, though.

Couldn't be happier as a customer.

Alright, so this just landed on our doorstep yesterday. Right out of the gate, it seems to be doing what it's supposed to. Big win that the carafe is glass instead of plastic, fits right into our fridge door like it was meant to be there. The controls? Couldn't be more user-friendly. And they tossed in a QR code for a free extra carafe, which we jumped on today—let's see how that plays out. We're dealing with municipal water that's not terrible, but not great either—38 TDS, with a hardness of 7, according to the last report we checked. After giving the system its initial flush and running a few carafes through it, this machine was pulling down TDS readings of just 01. That's a noticeable drop in the mineral taste, and assuming those readings are on the money, it's stripping out a decent chunk of whatever's left in our tap water. I get the feeling it can't legally show a reading below 01, but who knows, maybe it's actually getting it down even lower. Now, couple of gripes: First off, the tank at the back's on the small side, so you're back and forth refilling it more than you might like. I get it, bigger tank means a bigger unit, so you're trading off with space. But maybe they could sweeten the deal by including an extra tank in the box. Second thing is, even though this model's more water-efficient than some others out there, you're still looking at a fair bit of waste water. If you try to game it by not topping up the tank, hoping to cut down on the waste, the TDS creeps up to 02—not the end of the world, still drinkable, but it shows even a fresh filter's got its limits. You need a decent amount of clean water to kick things off. Waste water's part and parcel with RO systems, but worth mentioning since we're all trying to be more mindful about water use. If you're new to RO, just know you won't be using every drop you pour in—some's gonna get tossed. Overall, though, feeling good about this purchase, even if it did hit the wallet a bit harder than we were expecting.

With hard well water at home, this RO system was a stopgap before getting a whole-house setup. It's been one of my best purchases, transforming the taste completely. Been using it non-stop since August '23, and the filter's still going strong. Highly recommend for anyone in limbo about their water setup.

This has been a lifesaver, no more lugging water bottles from the store every week. I think everyone could benefit from one.

Super quick delivery and the packaging was impressively secure. Setting it up was a breeze, and the water tastes like a dream compared to tap. Absolutely worth it, don't second guess, just go for it. Also, the mineral add-back option has been great.

Just brought this sink top water filter into my life, and let me tell you, I'm over the moon with it. Checks every box for me and has been a fantastic addition to my kitchen setup. Here's the rundown on why it's getting a glowing five-star review from me. First off, the size and fit are just perfect. It tucks in next to my sink without monopolizing space, leaving plenty of elbow room for everything else I need to do. And it doesn't just blend in—it's got a style that actually enhances my kitchen's look, adding a dash of elegance. Now, let's talk bang for your buck. This water filter's price point is spot-on for the quality you're getting. When you stack it up against other options out there, it feels like a steal. I'm all about getting my money's worth, and this filter delivers. One of the big selling points for me was how user-friendly it is. It's a hit with the whole family—kids included. No complicated maintenance or tricky operations. Wrapping it up, I can't recommend this sink top water filter enough. If you're in the market for an affordable, effective, and hassle-free way to get your hands on clean drinking water, this is it. Its size, price, and ease of use are a winning combo for us. Totally satisfied with this purchase, and it's going to be a staple in our kitchen for the long haul.

Really handy, especially with the detachable water tank. One minor hiccup is a bit of leaking when removing the tank for a refill, but a dish cloth handles it. It's sitting pretty on my stainless steel cart, which is a nice touch.

Decided against a built-in system and couldn't be happier with this choice. It's been keeping up with our high water intake perfectly. Love the simplicity of having just one filter to worry about. Hoping it stands the test of time.

It's become a daily staple for me. The difference in the water quality, especially for tea and coffee, is night and day. Super easy to use.

Totally in love with this system. It's stylish and the water tastes phenomenal—like something out of a high-end restaurant. It was a bit of a splurge, but absolutely worth it. We do add minerals back into the water to make sure we're not missing out on anything essential.

Perfect for brewing coffee and staying hydrated.

Just wish the reservoir was a bit larger, but it does the job well, and the water tastes great!

Having an allergy to something in the water meant bottled spring water was my go-to. This system's not only healthier but also more convenient and, in the long run, cheaper. The filter's lasting way longer than I expected, too. Plus, the glass pitcher's a hit—I got a second one to add minerals back into the water. Trying to be eco-friendly with the water usage and reusing the "waste" water wherever possible.

Using it for my humidifiers and plants has been a revelation. No more dealing with the white dust from my softened/chlorinated water!

Two weeks in and it's been a great addition. Didn't want to mess with my new countertops, so this was the solution. Seems perfect for one or two people. Just crossing my fingers it keeps up the good work.

Loving this system. The convenience compared to hauling water bottles up to my condo is a game-changer. Used to dread those trips and finding storage space was always a hassle.

Really impressed with the quality. Totally recommend it!

Unboxing to first use was smooth sailing. Made about 10 gallons so far and it's been great. Noticed some say it's slow, but as a party of one filling gallon jugs, it's been speedy enough for me.

It's hitting all my expectations. Water's great, doesn't take forever to refill, and it's pretty quiet. Doesn't crowd the counter, which is perfect for us four. But the promo for an extra carafe that turned out to be a no-go was a letdown. Felt a bit bait-and-switched there.

Swapped out an old model for this since I couldn't find filters. Setup was a breeze and the water's top-notch. The glass carafe's a tad smaller than my last one, but it filters fast. I just filter a few carafes back to back and transfer to glass jugs for all my drinking and cooking needs.

Three months in and the water's tasting fine. The constant tank refills are a bit of a drag, but that's the trade-off for not going the plumbed route.

Grabbed this to cut down on water costs. We've got PFAS issues here, but this setup deals with it, no sweat. The water ends up distilled, which took some getting used to, but now I'm all about it.

As a self-confessed water snob in an area with sketchy tap water, this filter is a godsend. Fresh-tasting water without a trace of the nasty stuff. Was hoping it'd be a cheaper alternative to bottled water. Looks like breaking even might take a while, plus there's the frequent tank emptying.

Been on my reverse osmosis wishlist for ages. Opted for the smaller size and it's just right. It's sizable, but can't imagine how the larger one fits on a counter. This thing's made me up my hydration game. Can't shout its praises enough.

Jumped on the reduce-plastic bandwagon and this water filter was my first recruit. Super straightforward to use and it zaps contaminants like nobody's business. The chlorine smell from the tap is overpowering, but after it does its magic, the water tastes fantastic—even the next day. Only had it a few weeks, but it's been awesome so far!

Spent ages digging through reviews to find the ultimate water filter and landed on reverse osmosis as the gold standard. Being in a rental, a fixed system was a no-go. This countertop unit was the perfect compromise. Doesn't hog the counter, simple to use, and it's got some serious style points. Refilling the tank is a bit of a routine, though.

I'm all over this thing, using it non-stop. Hands down, the best gadget in my kitchen. Big fan of the glass container—it's a game changer for dodging microplastics. The filtering speed is insane. Got a bit of a hiccup though—it doesn't know when to stop on its own. Left it unattended once and almost had a mini flood. There's a workaround with a half-fill option, which is pretty neat. Just wish it could auto-detect and shut off to save me the hassle, but honestly, it's a minor thing. Haven't found anything else out there that can hold a candle to this beauty.

Setup's a breeze and the water looks and tastes pure. The glass carafe is pretty but feels a bit delicate.

Been using this for three months and it's lived up to my expectations. A UV light and a solution for the waste water going back into the source tank would be nice improvements. The TDS sensor doesn't track the initial flow, but the overall water quality is definitely improved.

Our old countertop RO system from another brand finally gave up the ghost. Went hunting for something that was easier to clean and maintain, and this one ticked all the boxes. We're both working from home, and with two big dogs, we're constantly needing clean water. It's easy to use, a breeze to clean, and the water? Fantastic. We're loving it.

Grabbed this at the end of May, and it's time for a new filter, just planning ahead. This machine's been a delight—simple to use, dependable, and for me living solo, the filter's about to last a whole year, which works out cheaper than all the pitcher filters I used to go through. Big recommend from me.

Not gonna drag this out too long. The toughest part of getting an RO system was choosing from the hundreds out there. Ended up going with this one. It's the right size, delivers great results

Super happy with my purchase! Picked this up mainly to fill up my new IonBottle Hydrogen water bottle. Really digging the color, too. There's a bit of worry about it pulling too many minerals out of the water, but I'm still drinking our regular filtered water alongside it.

Absolutely smitten with this portable, easy setup, chic, and user-friendly water purifier. It's like it was made for hassle-free living.

This thing's a breeze to use, got a simple on and off switch. The water's tasting way better now, and the tank's got enough room so you're not constantly refilling. Plus, it's got a pretty cool look to it, though personally, I'd lean towards something in silver or black.

This countertop reverse osmosis rig is the real deal. Sleek looks, but more importantly, it delivers on performance. We grabbed the version that's sized for two people, and it fills up a carafe in around four minutes flat. Only reason it's not getting a full five stars from me is the waste water situation. Wasn't fully up on how reverse osmosis works—turns out, it needs water to push the junk into, meaning you're not using about half of what's in the tank. There's a line you're not supposed to filter below, but the machine's not stopping on its own; you've gotta keep an eye on it. That aside, the water coming out of this thing is top-notch, and the machine itself couldn't be easier to use. I've definitely upped my water intake since we got it. Highly recommend, despite the waste water hiccup.
