5KDC Under Sink Water Filtration System, Direct Connect Under Sink Water Filter, NSF Certified 5K Gallons Ultra High Capacity, USA Tech

Works great and simple clean installation kit and fittings. Good water quality.

I've been using this filter for about 3 years now. Love the quality and taste of the water that comes out of my sink tap, and love the price point for the filter. The first instillation was super easy and this is coming from a girly who doesn't work in plumbing. *Edit: the complaint below no longer holds up as they sell the filter separately from the kit now. One downside is that Aquacrest does not sell this model filter (AQ-5KDC) outside of this kit, even on their main website. Meaning, every time I've had to replace the filter, I've had to buy the kit with the instillation parts I don't have need for. Wasteful. Although they have other filters that fit the system (the AQF-FF35C5J) the gallon per minute difference is huge. With this filter in the "AQ" kit having 1.5 gpm and the "AQF" being at 0.5 gpm. The low price point helps with the fact that I need to keep buying the kit over a singular replacement filter, but truly this would be 5 stars if I could just buy the filter alone.

what sold me on this filter is the math. 5000 gallons and 25$. i use the hot water mostly in the kitchen sink which is a separate source, so i knew that wouldn’t be using the filter. i calculated max a few gallons a day for drinking and washing fruit/veg, that’s all i use the cold water for on that tap, but it would take 13gallons a day to hit 5000 in a year, so even if my math is way off that’s plenty of room for error, and this 25$ for a year (or many years bc i won’t use it much) is WAY more cheap than anything out there. and you know the filter is done when the flow goes bad (finally dug up that answer). i saw another under sink for 50$ & 8000gal and the ones in the pitchers barely last long and we more expensive and take up excess space. this one hides away under the sink. another win. and look, even if you don’t care about tap water quality it’s better to be safe than sorry for just 25$ every few years, dead cheap. now install. well hindsight it is an easy install, just twisting some valves on/off/into existing piping to accommodate the filter. actually i was missing a tube that was later found, wow that makes a huge difference, obviously. it does come with two tubes and the needle quick connect male is inserted into the filter via a push compression valve, which is quite difficult to undo unless you know to hold the sleeve (the female white plastic hole on both ends of the filter that the silver male connector tube/needle goes into) down (towards the filter, don’t let white sleeve rise) then the male needle slides out of the filter. this is what you’ll need to do when you replace the filter. it says in directions to press ‘together’ the sleeve with thumb and index finger, but it should say hold it down, since that’s what keeps it lose enough to expel the male needle. once i found my missing tube i haphazardly inserted the needles into the filter only to realize i put them in the wrong ends. One needle was easy to pull out but the other one wasn’t, so i ended up using pliers to hold the sleeve down and it still took lots of force but finally got the needle back out. i feared i damaged the sleeve but luckily once i turned on the water no issues. i let it run a while to clear the initial sediment (looks cloudy for a while) then after 5 or so minutes the water was clear and for sure tastier and more odorless than unfiltered tap. extremely satisfied and disappointed i didn’t do this forever ago, who knows what i’ve been drinking. although i was using a fridge filter but the water function just broke so once i went back to unfiltered tap i realized how nasty it was and knew i had to find the best solution for taste and health sake. cheers guys!

Easy install. Good quality.
