Frizzlife 800GPD Reverse Osmosis Water Filter, NSF/ASNI 58&53&42&372 Standard, Alkaline Mineral pH+ Tankless Reverse Osmosis System, 9-Stage Under Sink Filtration RO, 2:1 Pure to Drain, PD800-TAM4

I have a whole house iron filter and water softner to correct high iron from my well. My TDS from water test was at 265ppm. From my understanding, a water softner adds some sodium to the water. I bought this item to reduce my TDS in my drinking water, while adding benificial minerals at the same time.After installation, my TDS were reduced to 12ppm.Installation was pretty easy for me. I had a faucet from years past, and had drilled the hole thru the stainless sink with a special bit. The instructions are easy to follow and straight forward. My only issue was getting power to the sink area. Tapped into my dishwasher power line to provide power to fizzlife unit. Total installation time was about 2 hrs.There is a slight hum when using this unit, but barely heard from under the sink cabinet area. The water has a fantastic taste after running thru the Tam 3 ph mineralizer filter! Its a pleasure to drink slightly alkaline water, and much healthier with added minerals.Water output from the faucet is decent, not slow and not really fast but somewhere in the middle range. Its a good looking faucet and well made, not cheap. Overall I am completely satisfied that I purchased this unit and Highly recommend it to anyone looking for great tasting water. You wont be disappointed!Lastly, customer service is outstanding!!!! Had a small issue resolved in a matter of a day on a Sunday to boot. They really back their product and support the customer 100%

Love this system.. easy to install and water tastes great. Fill speed is ok, could be better, but still good. Very quiet, barely know it's on. Highly recommend

I bought this Frizzlife filter to replace another brand tankless RO filter that malfunctioned after 18 months.Here’s my take when compared to the 3 other brand tankless RO filters I have:Pros:- Unit is solid and well built. Installation was easy. No issues. No leaks.- Water filtration is impressive: The TDS of my unfiltered city water supply is 330ppm with a ph of 7.2. This machine reads 6ppm after filtration but the alkaline filter increases it to 28ppm with a ph of 8.7.- The taste is quite good and I think a little better than the other RO filters I've owned. Taste is smooth and well-rounded with no sharpness.Cons:- It really doesn’t work at its best dispensing a single glass at a time. I need to dispense into a carafe and run about 30 seconds first to purge the water sitting in the alkaline TAM3 final stage. If I just filled a glass with glass without running it first, I would end up with a TDS of over 75 and a ph of 9.2- There is NO phone or even chat support. To get help with a question I needed to email Frizzlife and wait for their mail reply. I had 2 quick questions, which could have been handed in a 2-minute phone call but it took me 4 days and several back-and-forth emails to get them answered - this was really disappointing.- This one makes slightly more noise. I put some vibration pads under the unit which helped.- When recovering from a power interruption, you need to run the filter for a few minutes straight to get the TDS meter working again.Overall would purchase again but still a little disappointing there is no phone support if I have a quick question.

Installation was simple. The application for this reverse osmosis system is for an espresso machine which previously had to be sent to the manufacturer for scale removal. We were advised the mineralization cartridge values are as follows:K: 0.3~1.5 mg/LCa: 0.5~8 mg/LNa: 0.1~8 mg/LMg: 0.1~1 mg/LWe are hopeful that the Frizzlife system reverse osmosis, water treatment with this remineralization will prevent further scale buildup, while, at the same time, provide minerals for great tasting coffee extraction. We will update. Will now purchase another unit PD800 and integrate another remin cartridge , very satisfied with PD 600 and will use for drinking water. PD 1000 will be used for espresso machines.We have purchased two units 2nd unit PD 1000 TAM4:Both the tapwater and the well water in southwest Michigan is contaminated with 100-225ppm chlorides. Which are guaranteed to cause damage to very expensive espresso machines. Only reverse osmosis will remove chlorides. Frizzlife PD 1000 eliminates almost 100% of these and other contaminants. The TAM4 re-mineralization filter provides adequate minerals for good espresso machine operation as well as good mineral balance for coffee flavor extraction. We highly recommend this product for cafes and home use. Some say the TDS is high after letting the system set for 8-10 hours. Please know this is expected, as the RO water that is restin in the remineralization filter has collected more of the healthy minerals. This is actually a good result! If one wishes a certain level f minerals, they could fill a fairly large pitcher. The TDS results will then be diluted. A water hardness test should be performed before using this water in your very expensive espresso machines! Also note that it is highly recommended to use a water softener upstream of this reverse osmosis system when the water will be supplying espresso machines. The ideal water hardness for espresso machines is between 50-80ppm Total Hardness for best taste and to avoid machine damage.
