I recently installed the Frizzlife Under Sink Water Filter System, and it has exceeded my expectations! This filter system is NSF/ANSI 53 & 42 certified, ensuring that it effectively removes contaminants while enhancing the taste and quality of my drinking water.The installation process was straightforward and hassle-free, taking less than an hour. The clear instructions made it easy to connect the system to my existing plumbing without the need for professional help. I love that it doesn’t take up much space under the sink, leaving room for other essentials.Since installing the filter, I’ve noticed a significant improvement in the taste of our tap water. The water tastes fresh and clean, and I feel much more confident about the quality of what I’m drinking. The filtration system effectively reduces chlorine, heavy metals, and other impurities, which is crucial for my family’s health.Another feature I appreciate is the filter replacement indicator, which makes it easy to know when it’s time for a change. This system not only saves us money on bottled water but also contributes to reducing plastic waste.If you’re looking for a reliable and efficient under sink water filter system, I highly recommend the Frizzlife Under Sink Water Filter System. It’s a great investment for anyone wanting to improve their water quality!

Easy to install, keeps water clean for a long time, doesn't slow the flow too much, though the reduced flow is noticeable. Keeps my coffee and tea tasty.I just changed the filter for the first time, and it immediately started leaking. I had to disassemble the cartridge to clean and grease all of the o-rings to seal it. That's not in the instructions, and the filter change kit does not include the plumber's silicone grease. I still think it's worth it, but this should have been in the instructions, or noted in the replacement filter kit somewhere.Edit 10Aug2025: I emailed Frizzlife support to see if the leak I encountered was a common problem and then sent me a replacement cartridge to be sure the o-rings were properly sealed. Great customer service!

I've had this filter for 6+ months now and felt like it was time to put in a review. First things first, you should never trust a review from someone who just installed a consumable system like a water filter, as it will typically perform very well initially and issues arise down the line. Let's start with the good here:It's inexpensive for the advertised flow rate - this is one of the only filters on the market that advertises over 2gpm, and it is capable of reaching that with a brand new filter. However, at least with our water source (New York City), that performance degrades SUBSTANTIALLY after a few weeks, to the point where it gets down to a trickle. Frizzlife stood behind their product and sent a second filter, but the same thing happened again within a few weeks so it seems our water's particular composition and this type of filter media don't play nicely together. I solved for this by installing a pressurized water tank in line after the filter stage, more commonly used with Reverse Osmosis systems (but works perfectly here as well) so that the first quarter gallon is full speed ahead even with the water supply shut totally off (and the tank refills as it dispenses) - this has resolved my flow rate issues permanently.Good quality metal hoses are included, but unfortunately that's more of a problem for me because my existing water filter connection requires push to connect plastic fittings. I fashioned an adapter from a 3/8 NPT to 1/4" push-to-connect after the tank stage to address this, but it would be nice if they included a few adapters in the box because they're surprisingly hard to find but cost next to nothing.It's definitely doing something! Take a look at the picture above, about 5 months after the filter was installed it's absolutely disgusting looking with the color of a cigarette filter. This will not lower your TDS reading, and they're very clear about that, but the drinking water it produces tastes good and clearly lacks the nasty stuff it's pulled out above.Now, let's talk about the bad parts:This is only a direct connection if you have the rare filtered water spout that accepts a 3/8" NPT or 1/2" NPT connection, as these are the only connectors and adapters provided. If you look at any of the most popular filtered water faucets sold on Amazon, the vast majority use 1/4" quick connect push-to-fit connections. Whether or not you think there are long term reliability issues with such connections, that is what most people already have in place, meaning you're headed to the hardware store to try to rig together some kind of adapter, which is likely to have more leak potential than a direct connection. They should at least include adapters they've tested and endorse in the package to avoid this.Removing the filter assembly from the bracket is super easy, it rotates out and twists off - anyone can do this. However, you haven't changed your filter at that point... this is not a drop in replacement - they sell the inner filter medium by itself, and include a special plastic wrench for opening the filter assembly housing to replace the medium. This works great when it's new, but when I went to change filters (see above) it would not budge under any circumstances - I put it in a vice and used a mallet to the point that the plastic wrench started to strip. I ended up having to buy a set of oil filter pliers to counterhold and twist, and finally was able to open it, but this is exponentially more difficult and time consuming than a system like 3m Filterete where the replacement filters come ready to screw in. I get that it saves plastic and likely benefits the environment, but man, their implementation is not up to the task.Tl;dr?Good performance for the money but changing filters sucks and it doesn't come with what you need to connect to the vast majority of filtered water faucets, ice maker lines and other things you might need filtered water for. I wouldn't buy it again but I'm also not going out of my way to replace it now that it's plumbed in.

I was looking for a water filter that didn't need a separate faucet since that would be difficult to install with our countertops. As I researched I also became aware of the NSF/ANSI 53 certification, and since we live in an area where PFAS are a concern, I also wanted a filter that carried that certification.This water filter met my criteria and was very easy to install. It just takes installing the mounting bracket and then inserting the filter into the water line. The included hardware and hoses feel very high quality. I also like that filter changes on this product replace just the inner media, so there's no throwing out a big hunk of plastic on each change as with the filter in our refrigerator.We are on a municipal water system and the supplied water drawn from wells is perfectly drinkable, but is relatively hard and has some taste issues. The filter definitely improves the taste of our water making it pretty much neutral, which I think is how water should taste. I think there might be a very slight reduction in water flow with the filter in place, although it's small enough that I'm not really sure. I liked it enough that I bought a second one for another sink.
