Aquasure Premier 4-Stage RO Reverse Osmosis Under Sink Drinking Water Filtration System Removes 99 of Contaminants 75 GPD

It’s been almost 5 years since I bought my last RO system from APEC and it has performed admirably during its 5-year run. I was really satisfied with the taste of the water and the way the system is built, but the effort of replacing the filter still leaves a lot of rooms for improvement. I started researching on another RO system and one of Aquasure’s ad popped up on my Facebook feed. A twist styled RO system that suppose to provide great water filtration with easy install and maintenance. Their website also goes into great details on why the system is an upgrade to the standard reverse osmosis systems that are on the market today. The whole package was very well thought out and everything seems to have its purpose in this well-constructed system. I decided to pull the trigger once again and bid farewell with my old faithful system. The system arrived nicely packaged and organized with 3 inner boxes that separate the system, the tank, and the accessories. unlike the standard RO, these filters are built into the housing and are already pre-installed along with their leak-proof safety mechanism. All I really need to worry about is to connect the supply tubings to the existing connection. The whole process took me no more than 10 minutes since the connections are all 1/4" which is the same as my previous RO, the only thing that I decided to change is the tank and the feed water adapter as I feel that the new feed water adapter that comes with the Aquasure System is much better. One other thing I notice is the fittings have built-in o-rings so I don't need to fiddle with Teflon tapes and trying to guess how much of it I need to apply. The system still supplied a row of Teflon tape which was odd to me, but I guess some people will find a use of it depending on their setups. Although my install was very easy due to existing connections already made on the previous RO, I still can see how the new system's design is more superior than the old one even for those that did not have an old setup. After flushing the first tank of water which takes about an hour to fill up. I conducted a simple TDS test that results in about 94% of TDS rejection, which is comparable to the previous system. The water tastes just the same as well with a tiny bit of sweetness to the water. Overall, I really like how the Aquasure System is packaged and how easy it is to change the filters. I really like my old RO system as well, but don't really missed the effort it takes replacing the filters and making sure that everything is tightened properly. The new RO system will be a welcome relief when its time for replacing its filters in the future. For those of you that are looking to buy and install your own RO system, this one is definitely worth to consider. Read more

I've spent 3x as much on other sink RO systems in the past and this has been the easiest to setup with the best filtration. The water PPM went from 300+ to <4. It's extremely functional and so far haven't had any issues with it. No leaks - just remember to press those tubes if further than you think you need to. Read more

Produces nice clean water that tastes good. Installation was easy, and there was no surprise. Also, their tech support team was amazing at handling an issue that I experienced with one of the parts. Read more

The water for our county has always had a bad taste and this filtration system helped tremendously. Can now drink the water straight from the faucet that came with it. Only took a couple of hours to install. Read more

I bought the Aquasure RO after buying a different RO over at Costco, which I quickly returned for leaks and being really noisy when the tank was refilling. No such problem with the Aquasure, it was easy to install, and is not noisy at all. I really like the compact filter set up, that has it's own base...I didn't even have to hang the thing on the side of the interior cabinet. This appears to be a quality system for sure,...I'm taking 1 star off for a tiny leak that was on the front side of the "Shok-Block" connector, which I think is there to protect the system if you have high water pressure problems...I tried reseating the quick connect hose that ran into the Shok-Block, but the tiny leak persisted...so I opted to remove the Shok-Blok (which is easy to do) and ran the inlet hose directly in the filter housing...problem solved. This is a small complaint, I'm really happy with the purchase. Read more

We had disgusting water and this cleared it up like spring water! Excellent purchase and well worth it!! Give it five stars! Read more

Overall happy. I like that it only puts 1.5 gallons of water down the drain for each gallon of RO water. Best I could find. The unit I purchased had most of connections already made versus the on line video. However as my sink cabinet is extra large I had to purchase extra pex line. The faucet body was well built but the top was plastic. It has a quick change feature to change the top part when it breaks. In any event I purchased a non OEM fully SS faucet and worked fine as did not want to deal with the top part of faucet. Also this did not come with a quick change water line connector for the faucet or a splitter for my ice maker.It does come with everything to make it work however. Really a easy install especially since all connections are made for you on unit. It did arrive in a crushed box so shipping could have been better. Read more

I bought this to replace a smaller unit that no longer was producing water fast enough. In spite of the fact that it has a larger tank, it acutally has a nice small footprint when you mount the unit on the cabinet wall. The water tastes good and tests show it is removing lots of ions. My only real question is that the water comes out with lots of tiny bubbles, so it looks cloudy at first. But the bubbles clear quickly, so it is not an issue. Read more
