    Not the greatest flow, faulty part.
    3 out of 5 stars
    Not the greatest flow, faulty part.
    I thought that this would be a quick install. The water supply fitting is faulty!!! Where the 1/4" valve screws in the fitting has just a single thread. I put lot of Teflon Tape on but still drips. The threads on the main fitting don't look like American tapered threads that tighten as you screw them in. Also the supply valve the a tiny entrance hole. The flow of water is restricted by this fitting. My refrigerator has same size tubing and the flow is much greater. Slightly disappointing. Instructions say the UV light turns off when no flow. Light always on and water gets warm.
    Thank you for your feedback

      I purchased this Bluonics 4 stage drinking water filter to replace a 20+ year old single carbon block under-counter filter system that was becoming difficult to find filters for.

      I hung the Bluonics filter system beneath the kitchen sink counter on a cabinet sidewall making certain to leave room below the canisters for filter element replacement and room above for UV lamp replacement.

      CAUTION: To reduce possible hydrostatic damage and leaks, after installation but before turning on your water supply, open the filter's faucet to allow air to escape as the filter canisters fill.
      It can take almost 2 minutes before you get water flow from the faucet. Run the filtered water for at least 5 minutes to remove loose carbon dust and air bubbles that will make the filtered water appear cloudy.

      The Bluonics came with everything needed to install (including 3 filter elements, uv lamp system, fittings, tubing and faucet) except the mounting screws and 3/8 inch to 1/4 inch tubing adapter needed for my install.
      I decided what I needed and purchased before attempting installation.

      All connections to and from the filter are push-to-connect ( PTC, aka SharkBite).
      My old filter was connected to a dedicated shutoff valve under the kitchen sink. The valve has a 3/8 compression fitting outlet. This filter's tubing is all 1/4 inch so I found a 3/8 to 1/4 PTC tubing adapter and connected to my existing 3/8 tubing. That adapter saved having to replace the shutoff valve.

      The old filter output was also 3/8 inch tubing to the old faucet with a 1/4 inch icemaker tap.
      I replaced the old 3/8 inch faucet with the included 1/4 inch faucet and purchased a 1/4 inch PTC tee which connected filter output to new faucet and icemaker inputs.

      I read several reviews that complained about no way to connect the filter's 1/4 inch tubing to the included faucet. Unless the part was missing, that is not true.
      The faucet input fits the 1/4 inch PTC coupling included in the parts bag. One end pushes onto faucet and 1/4 inch filter output tubing pushes into the other end.

      Other reviews complained about not being able to determine filter input and output. Common sense would dictate that input goes into the first filter housing and output comes out of the UV lamp assembly.
      NOTE: You will need to remove the tubing plugs from filter input and output by compressing the tubing release tabs.

      Several reviews complained about leaks. I had zero leaks after installation. Each filter canister has a rubber o-ring. After installing each filter, tighten the canister by hand then use the included filter wrench to snug closed. Over tightening will deform the O-ring and cause a leak. Lubricating the o-ring with a compatible lubricant will add to its life.

      The UV light housing gasket is tricky and the illustrated instructions only made sense after figured out I needed to push the knurled nut OVER the gasket and glass tube end.
      Overtighening the nut will deform the gasket and leak. The extra o-ring was confusing and unnecessary but will work as a spare if needed.

      I plugged the UV light ballast into a receptacle under the sink that I added when installing a new dishwasher a few years back in preparation for an eventual UV water filter. 🙂

      Be certain tubing pushes into all PTC connectors at least 1/4 inch or it will not lock. Make a mark on the tubing 1/4 inch from each end to help as it is possible to push in the tubing part way.
      Pull on each connection after pushing tubing in. It should not come out unless you press in the tubing release.
      BE SURE TO USE THE INCLUDED LOCKING RINGS ON EACH PTC CONNECTION to prevent accidental release of tubing.

      As others have mentioned, the filtered water will come out warm for the first few seconds as the UV light is always on.
      I read about some systems including a flow switch so the light only comes on when water flows but this one doesn't have it. Maybe a retrofit later but not worth the effort to build one in my opinion.

      Our city water supply is chlorinated, fluoridated and tastes terrible, not to mention the invisible dead things killed by treatment. Most municipalities will recommend filtering their end product.
      The filtered water has no detectable taste to me and is especially refreshing from the refrigerator's cold water dispenser.

      I believe the flow rate was advertised as 1/2 gallon per minute but I'm getting at least a gallon per minute. A little less than my old filter but more than I expected from this one.

      For added safety, we always turned off the water supply to our old filter if going on vacation and will continue that practice with this one.

      At this point I am happy with this system and would recommend it.

      Good luck.

      Agree with others that installation instructions are inadequate. There were a couple parts missing and a couple extra parts with no explanation of their use. Fabricated a locating washer from parts from hardware store. Left message by phone with supplier but never got a response. After figuring out UV cap tightness, unit quit leaking. Once everything done, unit seems to work well and provide good tasting water. Unit seems well designed - if they had better instructions I would rate it higher.

      I like the low price. Works well. Replacement filters are inexpensive also. $100for 3 ewch (there are 4 filters, one is a uv light). We used this system in Costa Rica with river water and rain water, so we had to change filters more often than normal city tap water would require.we loved it, but sometimes after replacing filters id have to be super careful with tightening the compartments that house the filters, because of water leakage. So put the system in a casserole dish with towels around for emergency leakage after initially changing filters or installing.
      ALSO the uv light housing fills with water to be purified by the uv light. The uv light bulb is also inside of a separate component, which is a fragile glass tube. I emphasize fragil. This is intended to protect the uv bulb from water exposure. Several times leakage and ruined uv

      Great product! Installed before a big Thanksgiving dinner and it has worked great with my new faucet. It was easy to install, not award winning instructions but they were good enough. I made one funny mistake and had water on the floor. Make sure everything is hooked up and installed ( including the UV light) before any testing. Also, I’m using it on a well system under the kitchen sink and it is working good for 3 weeks now.

      Works excellent. Have well water that we didn't use for drinking, used bottled water. Since installing the water tested fine for drinking and tastes good. No more bottled water! Installation was no problem all parts were included installed in about an hour. Only issue is the filter wrench provided broke on installing filters.

      This does exactly what it says it does. It comes with every thing you need. I installed this in my fifth wheel under the sink. I put a switch in to shut off the UV so it is not on all the time. Most of the time I feel confident that the water I am using does not need more than just the filtering with out the UV, but now I have it when needed. The price on this is very good but the instructions are lacking. Number one; there are two kinds of press in fittings that come with this. The one for the faucet is not a problem. Simply insert the tube stabilizer, into the tube and then press the tube all the way in and you're good to go. The others have little blue collars that must be removed , then the "bulge" can be pushed in to remove the little "Trumpet" protector. Throw that away, it is just there for shipping. . Press in the tube all the way , pull the "bulge" out and replace the little blue collar, ring, thingy. One more suggestion; it is necessary to remove all the filters before you start. They are all in the original packages. You might want to label the containers. The first stage seems obvious to me. It is a sediment filter. The other two are very similar carbon filters. When reinstalling the canisters, check that the "O" rings are in their slots. You should be able to have a sealed unit with just hand tight pressure. If you have major leaking, the "o" ring did not seat and you need to start over. Do not try to just tighten as you will then need a new O ring.
