The tap water we use at home had a strange smell.our home is 10 years old. My wife wasnt comformtable using it for drinking or cooking even after it goes through a regular filter. I bought the APEC ROES-50 system after much research. Both me and my wife are completely completely satisfied with this purchase. Water tatses awsome now after installing Apec RO and and there is no stink in the water either. Qyality at the Price: I had veen putting off buying an RO previously due to the cost involved with other systems. But Im gappy to report that Apec RO system delivers quality at a reasonable price. Installation: I also worried about the installation. But it was an easy DIY. Took me about 2 hours to complete. There are plenty of vidoes online and the instruction manual is detailed enough. The storage tank holds enough water for 3 adults through out the day. I could not hear any operating noise tha few people noted. The drain noise that some people noted can also be avoided if you follow the intructions properly . It fits under our kitchen sink faucet cabinet and neatly tucked away. I did not have to drill any holes in the counter top. I just replaced the spray hose with the RO faucet. Delivery and packaging: The product arrived in 3 days and packaging was good. No damage on delivery. The included faucet looks good and feels solid enough. Although it works on water pressure (not electricity), I found the stream of water to be ok and not weak. Water PPM: I tested the water from the RO and the equipment showed 6 ppm which is great and clean. Exactly what I expected out of the system. I would definitely recommend this system
