4.9/5 Stars, 1,500+ Reviews, & A Lot Less Bottled Water.
Countertop water purifiers are everywhere right now, and the claims all start to sound the same. Cleaner, purer, better tasting… on paper, almost every one of them delivers.
Editor’s Note: This Sans Product is $100 Off (For Now)
The Sans Water Purifier is one that, judging by its review section, more than delivers in real kitchens. Sans got its start during the COVID-19 pandemic with a clean-air purifier, and its countertop reverse osmosis purifier has since become the one customers won’t stop praising.

Here are some quick-hitter highlights:
- Built on 4-stage reverse osmosis purification
- Removes impurities down to 0.0001 microns in size, with a UV-C light as a final layer of defense
- Removes up to 99% of harmful contaminants, including forever chemicals such as PFAS, and microplastics
- A clever countertop design with no installation required
- An Auto-Fill Glass Pitcher that refills itself while docked
- Instant Hot Water Mode for tea, coffee, and cooking
- A built-in sensor that reads Total Dissolved Solids in real time, right on the front of the machine
But rather than relying on polished testimonials and marketing speak to determine if this purifier is worth the hype, we wanted to check where the conversation is the most candid: the review section. We read through what verified buyers have posted on the Sans site, and the same few themes kept coming up. Here’s what the people had to say:
“Once You Drink This Water Everything Else Just Doesn’t Taste Right”
Taste comes up more than anything else. Owners describe city water that smelled like chlorine, other filters they’d used for years, and the moment the first glass from the Sans changed their minds:



No More Hauling Cases of Bottled Water Home.
For a lot of owners, the purifier replaced a weekly chore: the trip for cases of water, the lifting, and the pile of empty plastic that followed.



No Plumber, No Under-Sink Install, Just a Spot on the Counter.
Reverse osmosis usually means a plumber and a cabinet full of tubing. The Sans skips all of that. You fill the tank, plug it in, and it sits on the counter like any other appliance. Owners seem to appreciate the setup almost as much as the water itself.




The Pitcher That Fills Itself.
The glass pitcher refills itself while docked, then lifts right off and goes straight to the fridge or the table. It’s one of the features owners mention most by name, and the heaviest users go through several pitchers a day.




Instant Hot Water, Straight From the Same Machine.
Then there’s a feature you don’t see on many countertop purifiers: Instant Hot Water Mode, perfect for tea, coffee, and cooking. For some owners it’s the deciding factor. For others, it’s one more reason the machine has earned its spot on the counter:

Everyone Drinks More, the Dog Included.
In a lot of these homes, the whole household got on board, four-legged members included.


What Owners Wish Were Different.
No product gets a perfect score, and the Sans reviews aren’t all five stars either. The most common wish is a bigger tank. The tank is refilled by hand, and heavier users say they top it up a few times a day (when you have water this good, everyone drinks more).
A few owners also mention that because the filters are only swapped once a year (every two years for the reverse osmosis filter), it’s easy to forget how it’s done.


Even here, most of the complaints come wrapped in praise for the water itself.
Why the Buzz Keeps on Growing.
Looking across all the reviews, a few things become clear. The Sans Water Purifier isn’t going viral because of one standout feature. It’s the accumulation of small wins:
- Water people actually want to drink
- Far fewer cases of bottled water
- No installation
- A pitcher that fills itself
- Instant hot water
- A design that looks good on the counter

Individually, each benefit is modest. Together, they add up to something more compelling. The Sans Water Purifier comes in at $499.99 $399.99… but from what we can gather, owners feel it more than makes up for the price.
The People Have Spoken on Sans: Here’s the Bottom Line…
Take it from the growing number of owners who’ve traded cases of bottled water for a countertop reverse osmosis purifier that looks good enough to leave out. The water is the headline, but it’s the everyday convenience that keeps showing up in their reviews.
It’s worth noting that on top of coming with a 3-year warranty, the Sans Water Purifier includes a 30-day risk-free trial with free shipping and free returns, so you can try it out in your own kitchen before committing to anything. You can subscribe and save 10% on replacement filters, as well.
