Review: One Year Later – Still the Best Purchase for Clean Water! - I’ve been using the Thereye Reverse Osmosis Countertop Water Filter for over a year now, and it’s hands down one of the best purchases I’ve made for my home. Right out of the box, it was incredibly easy to set up — no plumbing, no tools, just plug it in and fill the tank. As someone who rents, that was a huge plus. The water tastes amazing — clean, fresh, and no weird aftertaste like we used to get with our tap. I tested the TDS levels and consistently get near-zero readings, which gives me total confidence in the quality. Pros: ✔️ Pure-tasting water ✔️ No installation required ✔️ Fast filtration ✔️ Sleek, space-saving design ✔️ Easy-to-replace filters ✔️ Great for renters or small kitchens After a full year of daily use, it still works just like day one. Filter changes are straightforward, and the reminder lights are super helpful. I’ve also noticed less scaling in my kettle and coffee maker since switching to filtered water. If you’re on the fence, don’t be — this system is worth every penny for the peace of mind and the quality it delivers. Highly recommend!
Review: Updated Sept 27, 2024 --Terrible please read below updated info .. - Update September 27, 2024 —- DO NOT BUY OR DEAL WITH THIS COMPANY'S PRODUCTS. The water filter broke 2 days ago(have it for only 2 months) and despite 3 emailed to the seller but no response. Contacted desertcart agent to get my refund. Took off 1 star for broken machine, 1 star for each for no email respond. desertcart not allow me to leave no star. Not happy cuz they should have at least respond to my email. Original review -- First, delivery was ok but the packaging was bad because the top of the box was busted opened. After I opened it and get it rolling and water tested, I found the following: Noise level when it is running on flushing is 71db filtering water is 64db and dispensing water noise level is 67db. The noise test distance is 6” from the machine. Water TDS testings are followings: My tab water is 87 Poland Spring bottle water is 68 Briter water filtered is 56 and this brand Thereye reverse osmosis system read 6 but its own indicator showed 3TBS. That’s very good as far as I am concerned. The only problem that I don’t like is water wasted (I took off 1 star for this reason). Every time when the system asks to change water. You need to empty 40% of the water from the tank. I was surprised that the TDS waste water reading is 683. It’s lots of water wasted but also it showed the system works and you are getting good clean water. Bottom line is you get approx 2 qtrs of clean water(60%) out of one full tank of tab water. I am not sure how long will this filter last (in gallons). I need ask the seller, also how long of the shelf life of the new filter will hold so that I can get a spare filter. Update: After emailed the seller I found that the water filter is very expensive-$99 and she couldn’t answer my question of the water filter’s shelf life. I decided to wait for the water filter to go dead before I order one.

### ⭐⭐⭐⭐⭐ It works! Well worth
*by J***G on March 31, 2024*

Compared to unfiltered water, and purified water using this machine, I can definitely taste a major difference in the quality. The purified water taste distinctly much cleaner and there’s less of a metal aftertaste compared to just boiled tap water - which is how I drink my water before investing in this machine. I’m not a fan of buying water bottles because those money add up so in order to find an alternative to that, I found out about purified water machine. It sits on my countertop without taking up much space and is easy to use. The water filter speed is quick and it is easy to use even for a beginner like me who just got started with purifying water. The water tank is also large enough for me to not have to refill water often. With this machine, I am able to drink purified water at a reasonable price at the touch of a fingertip. The initial cost is a lot but in the long term, I am saving a lot of money and it is also beneficial to my health, so I consider this well worth.
