Frizzlife Reverse Osmosis Water Filter - Alkaline Mineral pH+, 600 GPD High Flow, Tankless RO Reverse Osmosis System, Under Sink, Reduce TDS, Compact, 1.5:1 Drain Ratio, PD600-TAM3ClimatePartner certified

Great product, my wife and I were worried about the PFAS, nitrates, arsenic and hundreds of other chemicals that are unfortunately in our water. The tankless system supplies on demand water with great pressure while giving us clean chemical free bottled water quality drinking water.We hooked up the unit to our refrigerator for clean ice and finally are ready for summer.The tankless ro is what you need to have good pressure to your refrigerator for the ice.The tds is at a 6 and after the mineral cartridge it's at a 20 which is the same as bottled water but minus the micro plastics.The system will pay for itself in a few months since we don't ever have to buy bottled water again!Keep in mind carbon filters are good but DO NOT remove PFAS or NITRATES/NITRITES. With all the cancer going around these days this is just a no brainer.

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.

I installed this system about a week and it's working fairly well. I have purchased and used about 10 different ROs tank systems over the last 10 years. I have installed the iSpring and Apec systems. I bought this unit to replace my Apec 5-stage system. Nothing was wrong with the Apec. However, I wanted to save space with tankless and try out the remineralization filter this comes with as well.installation:The unit was easy to install. But, keep in mind that i have installed RO systems a few times. And, in mine case, I was replacing a system. So, some of the work like the waste pipe hole was already done. And, I knew how to deal with all the fittings and such. Most every thing is easy if you have standard water lines under your sink. The kit comes most everything you need. You will need a drill a hole to install the saddle for the waste line. But, it's just one hole and easy if you are drilling into plastic waste pipe. Also, I already had a faucet installed from my previous RO system. However, if this a new install, you'll need to use an existing hole or make hole a new one in your sink or countertop. That could be the most difficult part if you are not handy. They have a video for the installing as well. Pretty good. I liked it. The quick install paper guide can also be used. But, if this your fist one, watch the video as well. Lastly, I thought the kit game with good parts compare to other systems. They were generous with kit and extra pieces. They even included a razor to cut the included piping down if needed.Filtering:I have not sent my water out to a lab for testing. Will do that if i keep this unit. However, my input in TDS is about 400-ish here. The unit's display claims 05-06 TDS output. And, at the faucet after the TAM3 remineralization filter, it readys 40 -100 (yes, weird that readings would vary that much). Keep in mind, TDS does not dictate water quality. That is just telling you the count of Total Dissolved Solids. So, those could be good or bad of is in the water. But, at least you know it's filtering something. Going from 400 to 6 is stellar. My previous RO went from 400 to 22.Water Flow:The unit claims about 600GPD. I measured about .40-45 gallon per minute at the faucet and half that at my refrigerator faucet (see section on refrigerator below). This water flow is a bit slow for sure. But, for glass of water, you are fine. If you need to fill a pot, you need turn it on and walk away for a bit for it to finish. The 600 GPD rating is reallygood and means that the amount in day that this unit can filter is substantial. My last unit was 90GPD. However, since it had a tank, the water dispensed faster than this unit. Of course, if you sit there and deplete the tank, you have to wait for more water to be generated. With this unit, even though the flow is slow, it's keep going and you won't run out unless you let it run for more than 30 minutes continuously at one time. After 30 minutes, the unit go into protection mode. Which is a good thing if you accidentally left the water running. Also, saves your filters too.Taste:This subjective, of course. I felt the taste was okay. Not sure if it will change over time. My previous RO system tasted better in my opinion. But, it might be because this one adds back the minerals. So, maybe I'm simply not used to it. Don't get me wrong. it's better the regular tap water. Just was exacting more of SmartWater taste. Again, I think it's a matter of opinion.Nice Features:1. TDS Display - this unit has a big digital TDS output display on the front. You can see it pretty clearly. This reading tells you what the unit outputs. I wish they showed you the input TDS value to the unit. That would be really nice.2. Filter Life Indicator - The unit has these bars in the display that show you when the filter life is up. I have not had the unit long enough to see if this works well. But, I like this too. Before on my other systems, I have to measure water TDS or mark on my calendar if they have just been there too long.3. TAM3 Filter bypass and maintenance - So, the external remineralization filter allows you to remove it without turning water off or unplugging the main unit. Also, if you want to bypass it, you can by removing it. I wish the main until allow this as well. The main unit requires you to turn off water and power to replace cartridges.Noise:I don't have pro db meter handy or a controlled sound room. But, using my phone DB meter, I saw about 40-50 at 2 feet away with cabinet door open. it's hard to really measure this as there are a ton of factors involved. Like your cabinets. Surface of the cabinet, how much stuff you have in your cabinet and such. Simply, I didn't think it was that loud for me. With cabinet door closed, it's really not that load. If you get this unit and want to reduce noise and vibrations, you can put a rubber mat or pad under it. I have water proof mat under my mine.Refrigerator Integration:I have Whirpool French Door unit and it states in the manual that it needs 40-60psi water pressure. I contacted Frizzlife support and they claimed their unit delivers about 14.5~29psi of water pressure. So, below what my fridge wants. Does it work? Well, kind of. I mean, my fridge makes ice. I have to empty the bin completely and see if this unit can refill completely in one shoot and how long it takes. But, I do know the ice is smaller and production seems slower. Where I'm really disappointed is the fridge faucet. This has dropped to half the water flow speed. From 6-8 seconds to fill 1 cup to 16 seconds. You have to really want water from there to wait there that long. The regular faucet is slow. But, this takes it do another level. Also, my distance from under the sink to fridge is about 18 feet. So, that probably reduce the pressure a bit. Unfortunately their support says there is no way to increase the pressure. This is something the tank systems can over come. Some tank systems by default have better pressure. But, you can alway add booster or pump to tank RO systems. If you need to connect to fridge, you might want to consider a different system.Customer Support:For most products, i don't usually contact their support. But, in this case, i sent an email in to see if anything can be done with the water pressure and speed of flow. The support responded very quickly and was very nice. They were very honest about their system and tried to help out. Unfortunately, they were not able to solve this issue. But, they were very responsive and tried to explain things to me. Most purchases on Amazon have terrible sellers with limited support. At this time, I thought Frizzlife was good and friendly.Overall Impression:I really really wanted to like this unit. Small, compact and good industrial design. I like the quick inserts filters and no tank. It saves a ton of space under the sink. And, you don't run out of water as easily as the tank system. Water tastes okay and you the minerals back your water. However, the water flow is really disappointing. If I can figure out how to increase pressure, I will return it and go with a tank system that does remineralization. This unit cost almost double that of other tank systems. So, I'm being picky for a reason. And, yes, there are tank systems with remineralization. If you are not going to use with a fridge, I think this is a fine system. But, right now my family won't use the water from fridge because of the slow flow.Anyway, hope my review helped. If someone figure out how to increase water pressure on this system, please comment. If that issue was resolved, I would give this unit a 5 star. But, it's losing 1 star right now for me due to water pressure.
