Excellent Water Filter!
I have been using the Culligan under counter water filter for the past 3 + years and I have been very impressed with the taste of our water. I cannot vouch for microscopic cleanliness of the water, but if taste equals clean then it is great! I have not had any issues with the system or filters leaking. The only possible negative I could have is the installation. It has to line up correctly before you can twist it in. No biggie, it is just a matter of getting into the cabinet so I can line it up correctly. Just make sure you turn off the water going to the valve first! Yes it is possible to make a mess with it. My husband appreciated that I was wearing a white t-shirt when I got sprayed down while replacing the filter. If you are on the fence on an under the counter water filter for your kitchen, I would go with this one again. The ease of replacing filters and the cost of replacements makes this a must buy. Amazon even offers subscription service for ordering. I got mine on every 6 months, that should be about right.

The difference is like night & day!
I have been using the RC-EZ-1 filters for 4 years now. These are a must have if you are connected to city water. In Florida every June the utility powers that be think that shock-treating the water system with mega-doses of chloramine is safe. I don't think it is. These filters work the best at removing these high levels of chlorine taste and smell. I change them every October 1st. I have been thru every other filtration system out there (within reason). The filter jugs, the faucet mounts, the counter top units have all been a waste of money. This is the one that works!!! It's easily installed and filter changes are a snap. The water tastes great and you're not removing the natural minerals, which occurs in an expensive Reverse Osmosis system. 'nuff said.

Outstanding product
Very easy to install, generates lovely clean water that tastes amazing. Some water filters are so slow they are maddening and hardly seem worth it, but the steady flow of this product makes pouring and drinking pure water a pleasure. The height of the spigot is wonderful for filling pans and cooking with pure water as well. I'd highly recommend this product and the ease with which the filters can be switched in and out is most convenient, even for older folks with arthritis like my parents. Thank you for offering this wonderful product at such a reasonable price.

AS GOOD AS IT GETS
This filter is made with simplicity in mind. To install all you have to do is twist left about a half to three quarters of a turn and it release the old filter and all you have to do is place the new filter in position and reverse the prior step. It's as simple as that! Even tho the filter is rated for 3000 gallons the company recommends that you replace it once a year. With it functioning as a ice maker filter for me it is still good when I replace once a year. Because it only takes a few ounces of water for each set of ice cubes made. When I've tested the melted ice cubes with a TDS meter(which measures the parts per million of solids) the meter gave a reading 175 which for me is a good reading considering the ease of installation and quality of the after filtered taste and at a descent price.

Can also fit on the BRTA system w slight mods
Can fit on the BRta system but you're going to have to cut off the plastic rectangle on top with scissors or knife carefully. Make it flat and the peg on the side has to come off also. Much better quality than the cheap aquifrcrat system. Bit more expensive but way better for the money.

Great Filter!
Going on my second filter and have another spare ready to go. I live in a 70 year old house with most of the original plumbing, at times cloudy, dirty water comes out of the faucets. This filter removes all discoloration and Chlorine tastes, I know it removes many other forms of bacteria and other contaminates but I don't test for it but other reviewers have. I use the filter daily to refill gallon water jugs, water bottles as well as rinsing my dishes after washing, filter last well over a year. I change the filter when the water flow slows to about half or more of the flow when new. Seeing is believing, the normally clear tubing running into the filter is now a brownish yellow color, the same tubing carrying water out of the filer still looks brand new.

Very good filters
I have been using these filters for about 7 years, very good quality and do a very good job filtering!!. I live in Venezuela, tap water is not very good quality, but this filter works really good. I'm using a sediment filter as a first stage and then this one for ice making machine and drinking water from refrigerator. Replacement is very easy, you dont need any tools or to shut down any valve, just turn the filter in the right direction, it will shut water line, replace, turn lock and done! You can use level 2 o 3 filters, but you will need to replacement them more often.

great quality
I bought the system through Amazon and easily installed myself. This filter came with it and I have run off approximately 2 liters per day, over the last 6 months or so, for drinking & cooking. I plan to change out the filter in June if the taste starts to degrade. I figure that one can run off 8 gallons per day for a year before change is needed if your tap water is already great quality. Strongly recommend.

Great product.
Was easy to install and works great so far. I hooked it up to my current cold faucet and needed to get another 1/4" to 3/8"adaptor. Water is clear and tasteless as it should be. I am happy with the product.
