Review: Great customer support - I’ve had this RO filter for 3 years now. It has served my family great. It’s our main drinking water supply. The water comes out tasting clean and fresh. Our tap water is good, but it’s hard and has a high level of dissolved solids, which is why we decided to get this system in the first place. It has resolved all those issues. I often test the water with a meter that checks the dissolved solids and it always tests close to 0ppm. When it’s closer to 5-10ppm I change the filters. The filters are a bit expensive, but they last a long time. I change them on average every 6-12 months. Depends on the readings I get on my meter. They’re a bit daunting to change the first time, but once you’ve done it a few times it just becomes another chore you can complete in 10-15 minutes. We used to buy large water jugs and this filter allows us to have unlimited filtered drinking water. I also use it for my indoor plants and my fish tank. Both the plants and the fish also appreciate the cleaner water. Install is not super difficult, but it does take some time and patience. For me it was worth it to avoid having to go buy filtered drinking water in large jugs once a week. I’m somewhat handy, but no plumber or anything like that. It’s totally doable for anyone that has some common sense. If you can build ikea furniture, this is very doable too. I recently had a leak in the center housing. After having the system for three years I guess something was bound to break down. I switched the o-rings and filters, but that didn’t fix the leak. I emailed APEC and got a response within hours. They asked for some basic information to verify my purchase and then proceeded to help me with my issue. Within a few exchanges I had the necessary part mailed out to me. I installed it, and now the leak is fixed. It was a bit of a hassle, but I appreciated the quick response, great customer service and overall helpfulness. I felt very supported with this issue. Exactly what you would expect from a company that cares about their product and customer base. Overall I’d say this product is for you if your tap water isn’t the best and you want an option that doesn’t involve lugging large water jugs. The initial investment is hard to swallow at first, but once it’s all connected and set up you appreciate having this filter set up. I find myself drinking more water than before since I know I essentially have an unlimited supply of filtered water. Having a meter that checks dissolved solids in the water takes the guess work out of changing the filters, IMO. It’s an extra purchase, but it’s cheap and easy to use.
Review: There is nothing like clean water, and plenty of it! - This is an absolute must-have during our unfortunate period of being forced to stay home (forced in a sense, but you know what I mean). Given, our install was within the breakroom at the office here, but some of us will be buying into these for our homes as well as it keeps us from having to worry about finding water in stores with so many hoarders selfishly taking all of the bottles for themselves. Why bother when you can have unlimited clean water at home without ever having to leave the house to buy more? For one, the price of this is pretty good for what you get. It is going to cost you less than subscribing to a Sparklets delivery service, while not much more than filling your jugs up manually at a local water store (I won't compare against the vending machine fillers as those are just plain nasty). Now, add the fact that you don't have to drive anywhere for it, or have to wait for a truck to bring it to you. The water is simply always there. Also, the price of the filters is quite reasonable. Don't get me wrong. They aren't incredibly cheap, but their quality thus far seems to be quite good and we appreciate that they aren't gauging customers like refrigerator manufacturers do with their (useless) filters (these are far better since they actually work). We had to take a (very detailed) vote with an email passed around, on which model should be installed in the breakroom. It was a toss-up between this one and the 6-stage option, which simply added alkalization. However, the final vote leaned heavily toward the 5-stage as the body needs some of its acidity to function properly. Thus too much (drinking nothing but) alkaline water could actually be a bad thing. So 5-stage option it was. Installation isn't too difficult, although it was a little more for our situation since 80% of the space under the sink (the only place we were allowed to put it) is located behind the guts to the sink without any way of actually getting back there (an odd design but looks nice on the outside). So we had to remove more than half the plumbing down there in order to get to the valves/supply in the back. Regardless, with 2-3 of us helping at any given time, he had the entire project (and the extension kit to the fridge, seen running through the cabinets in a frew of the attached images) done in around an hour and a half or so. This included a number of social distractions. As long as you are confident in yourself, you will be fine. Just remember, don't be shy with the teflon tape. If you see threads where something screws together, go ahead and apply some (even if the instructions don't say to). You can never be too safe when it comes to preventing leaks! They also give you enough, which is nice. It asks you to flush the system for the first time by letting the tank fill for 2-3 hours and then flush it out the faucet for 5-6 minutes. This is because the carbon filter initially causes the water to gain some blackness to it. This is true, although you will want to do this twice in our opinion (maybe even three times to be sure). After that, things seem nice and pure. Regardless, after the first flush, it is safe even if you see a little of the black dust left over. It's just the carbon dust from the filter and harmless. If you see what looks like tiny white residue floating on the top, that is also harmless--those are just micro-bubbles caused by the air/pressure in the line (they eventually go away). The PPM (parts per million) of the normal city water coming to the tap was close to 500 PPM (Las Vegas tap water is a bit nasty). The (useless and expensive) fridge filter lead to around 460-470 PPM and similar taste. The RO processed water is around 9-12 PPM. So this seems to be working quite well so far. As mentioned, we also got the additional kit to break off to the fridge as well. It took a little while for the fridge to flush things out so it was only using the new water, but now it has the same PPM. We will make sure to update if anything changes, but so far, we are loving this and there is many of us who plan to buy into one at home. -- Update 05/07/2020 -- So far, everything has been working fantastically. No complaints from anyone, including on the taste. We have also uploaded a few images now that desertcart has returned the option for customer reviews. **If you have found our review helpful, please vote it as helpful below so I know.

## Questions & Answers

**Q: How is RO water compared to bottled water?**
A: Just as good or even better. We use the same technology as other major bottling plants use to filter water. RO systems purify water daily in your home which is fresher and healthier compared to water that has been sitting in plastic bottles.

**Q: How effective is Reverse Osmosis filtration compared to other methods?**
A: RO is the most convenient and effective method of water filtration. It filters water by squeezing water through a semi-permeable membrane, which is equalse to 0.00000004 inch! This is the technology used to make bottled water.

**Q: What is the WQA and what are the benefits of purchasing a certified system?**
A: To receive WQA Gold Seal certification, a RO system must be constructed to meet strict public health standards and pass weeks of rigorous testing for material and parts safety, structural integrity, and contaminant rejection performance.

**Q: What is the size of the product, and if I move, can I remove the system to bring with me?**
A: The dimensions are 17.5"H x 16"L x 5.25"W, and the tank is 11"W x 15"H. This system is very easy to uninstall. Just close the water inlet needle shut off, take off the water inlet tubing, and take off the whole system in 5 minutes.

**Q: How often do I need to replace the filters?**
A: The filtration process is optimized to protect the RO membrane, so the prefilters (the 3 filters before the membrane) can last between 6-12 months, and the RO membrane & post-filters can last between 12-24 months depending on incoming water quality.

### ⭐⭐⭐⭐⭐ Ten years later...
*by V***C on February 25, 2026*

I bought this same system in February 2016 and placed my first review back then. This is my update on March 2026. This product has served me well for ten years. I live in the Southwest, and the tap water has a lot of minerals and tastes bad. After all this time, it keeps giving me great tasting water and friends on the area without this RO system, bring bottles to my home, so they can get some good drinking water to their home. Filters last long time, making the maintenance cost low. Installation is easy if you are handy. But you must be careful and not do it in a hurry. Now, If you want to know about potential problems and customer support read the following: After ten years I got some leaking that was not easy to fix, until I understood what the problem was. I learned that the canister caps can crack, especially if canisters are overtightened when replacing the filters. I discovered online that many people deal with this. To prevent this, canisters should be tightened by hand and with the tool just add 1/8 or a turn. When hard to deal with leaks happen, remove the canisters and look for very thin cracks on the caps. The only solution is replacing the "system head" with the three caps attached to the main metal support. Another good solution is to replace the whole system that comes with all filters. If you replace filters for the five stages, the cost is about half of the full system with the filters. So, if you have gotten five or more years of good service, it would not be a bad deal. That is what I should have done that from the beginning, but I did not know what was going on. So I almost $100 in the five stages filters plus O-rings. But that did not fix the problem. Then the system head was out of stock... I had to wait 6 weeks to be able to buy it. But the good people from APEC support went out of their way so that I could get the part really quick. I liked that they stood by their product. Now my system is working like a charm again!
