Review: Completely transformed our heavily treated municipal tap water—especially paired with a chiller! - If you are dealing with heavily treated municipal surface water, this system is an absolute game-changer. I bought the Value Bundle to handle our local tap water, and I paired it with an Express Water Universal Chiller for on-demand filtered cold water. The whole setup has exceeded expectations across the board. Water Quality: 5/5 Our city water is loaded with chloramines and has a high TDS from being sourced from open canals. This 6-stage system strips all of those harsh chemical disinfectants and dissolved solids right out. The peace of mind knowing exactly how clean my drinking water is, is priceless. Taste: 5/5 This is where the ROES-PH75 really shines. Standard RO water can taste unpleasantly flat, but the 6th-stage alkaline filter adds high-purity calcium back into the water. It perfectly replicates the crisp, refreshing taste of pristine groundwater—and having it flow right through my chiller means I get ice-cold, incredibly fresh-tasting water on demand. Value for the Money: 5/5 Getting the Value Bundle with the extra Stage 1-3 pre-filters is the way to go. Those carbon pre-filters take a beating from the city's chloramines, so having the replacements on hand to protect the expensive main RO membrane saves serious money in the long run. It easily pays for itself by eliminating the need to ever buy bottled water again. Durability: 5/5 The build quality is excellent. The filter housings are thick and heavy-duty, the tubing is high quality, and the fittings are totally leak-free once properly seated. It feels like a premium, commercial-grade appliance built to last for years. Ease of Use: 5/5 The installation instructions were clear, making it a very manageable under-sink DIY project. Swapping out the lower filters is straightforward with the included housing wrench. Plus, the system uses standard 1/4" tubing, which made hooking it up to my aftermarket water chiller an absolute breeze. Color: 5/5 The unit itself is a clean, unobtrusive white that looks neat and organized under the sink. More importantly, the water it produces is absolutely crystal clear with zero cloudiness or floating particles once the new filters are properly flushed.
Review: Best not to guess what is or isn't in your water, best option out there - This is my second system, we purchased a vacation home and wanted to enjoy the same quality water there as we do at home. Our area has very hard water and requires frequent cleaning to remove deposits. This system has had a deposit free faucet for 9 years while I have had to replace shower heads 3 times. This system is identical to the one we purchased in 2016 and installation was very easy. The hardest part was drilling a hole in the granite counter top then cleaning up the mess. The instruction book is easy to follow and provides the list of tools you'll need. There isn't any real plumbing experience needed just review the instructions carefully first and follow them and it will go smooth. The kit comes with feed line adapters for most installs so confirm before beginning. Having the under sink space and planning where the lines will go before you start is also a very good idea. The only tip I can come up with is to use the right amount of teflon tape on the storage tank and tighten the top valve until snug and then when the system is on come back and check for leaks and tighten the top until the leaks stop. Installing the filters into the manifold was easy, just follow the order. It is easier to tighten the filter housing with the unit on its side. I opted to mount it on the wall across from the dishwasher about 1/2 inch off the cabinet floor and this was easy but the instructions say its not needed, I just like it being off the counter floor. I was concerned with over-tightening so I had to tighten it over a few hours but once water stopped showing up I knew it was good to go. Drilling the hole into the drain line was easy enough but removing it really helped out. The instructions state the tank is already pressurized so no pump is needed, just don't open the faucet until you are ready to begin flushing the filters. I opted to add the ice maker kit to this and installing that at the same time was very easy and no mess. Over the years we have measured the water quality from this RO system and am still amazed and how low the TSS readings are compared to tap or even fridge filtered water. The water purity isn't even close, this system removes everything. The PH filter adds back in the right amount to give the water a pleasant taste that everyone prefers over plastic bottled filtered water. We have never had to run vinegar through our coffee machine, tea kettle, and the rice cooker/instapot are easier to clean up too. Given some of the problems with water in the news I wanted to be safer than sorry as this is cleaner, more cost effective, and better all around than getting filtered water delivered or plastic bottles of water.

## 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 15.5"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.

### ⭐⭐⭐⭐⭐ Fixes well water 100%
*by J***J on February 8, 2026*

I’ve been extremely happy with the APEC ROES-PH75 system. Installation was straightforward with clear instructions, and the build quality feels solid and well thought out. The water quality difference was immediate — noticeably cleaner taste, no odors, and much smoother than our previous filtered water. The added alkaline/mineral stage is a big plus. The water doesn’t taste “flat” like some RO systems can, and it’s been great for drinking, coffee, and cooking. Flow rate is excellent, and the tank refills quickly. After testing our water, contaminants dropped dramatically, giving real peace of mind. , this feels like a professional-grade system at a fair price. Would absolutely buy again and recommend to anyone looking for a high-quality under-sink RO system.
