Aquasana Water Filter for Sink Faucet | Reduces 99% of 78 Contaminants Including Chlorine & Lead from Tap Water | Under Sink Filtration | Claryum Direct Connect | AQ-MF-1

Purchased due to PFAS readings from our municipal water supply. The certifications were important to me and I didn't trust filters that supposedly last years. 6 months seems right, and while it's a new household expense, it seems worth it after installation.The parts & instructions were well made & written. Based on another helpful review, I purchased 3 inexpensive extra parts that eliminated the white piece that connects directly to the water supply line since it seemed to improve durability and ensure good flow. I hope they might upgrade their parts package to do this for future customers.The filter is long, and the best way to install under my sink was horizontal, which made it harder to reach the furthest screws, but not impossible, and now replacement is that much easier.Upon first test, heard the water try and make its way through but there was almost no flow. Long story short, something made its way to the faucet head, which once I cleaned it out, the flow seemed almost (90% or more) like pre-install. (Sigh of relief). I also had to reseat the connectors to the filter head housing to ensure no leaking. I put a small container underneath just to be sure, but it's been dry since day one.Water tastes very good, and it feels good to have done the best we can to improve the quality / health of our drinking water.

Well made. Great instructions. Works Perfectly…

(1) The template seems useless unless you mark accurate center holes and also include the extra length for a filter change. Put an “x” on the center?(2) my product installed with a 90 deg shut off valve. The fitting has a fixed end so the supply and return off the dual port adapter can hit the cabinet back wall and or drain line. It didn’t leak where I tightened down at - I feel I was lucky it lined up to install the hoses. Otherwise I’d need a small flex hose.My Purge was only minutes (could take up to 15min per manual)Overall easy to install - Time will tell.No leaks on a plumbing job so bonusWater flow is good.

I’ve been using Aquasanta for almost 15 years as I have changed from different types of faucets and kitchen sinks. I started off with her countertop and faucets have changed over the years that no longer works because it uses the old-fashioned adapters.I bought this version to install under my sink and tap right into the cold water line so that way I could have filtered water through the existing faucet.Note that when I installed horizontally using the brackets that come in the package, it did not work. Meaning that when I turned on the cold water with the cables going in and out the exact same way, as if I stood up the filter for some reason the water flow did not work.However, when I stood up the filter vertically, and the cable in and then the exit tube going back to the Cold-water line It worked without issue.Highly recommend this company and their products

I wanted to love this so much. We were "upgrading" from a Filtrete under-sink cartridge filter for our sink water to this one, on the promises of much improved filtering of bad things in our municipal water supply in Westhcester County NY. While this item was well packaged and a high quality item from an installation parts perspective, we were harshly dissapointed with the end product -- the actual taste of our water, which was metallic and undrinkable. In contrast, the wwater from our Filtrete filters, especially the Max version, was always excellent. We contacted the vendor and they sent us a replacement filter, but unfortunately the water tasted equally terrible. We are giving up and going back to the Filtrete max filter. All I can think of is that either there is some wierd chemical reaction between this filter and our water supply or maybe the plastic tubing that came with this filter was somehow contaminated. I will use the same tubing with the filtrete replacement I am going to set up, and then I guess I'll know for sure what the culprit was. Dissapointing.

Fairly easy to install. No loss in flow

This filter is amazing on paper but really lost me after about a year. The filter is easy to install with no leaks or fitting problems (at least for me). The water pressure loss on my cold water-only installation was severe, with my pressure going from great with no filter to OK with the filter, poor after about 2 weeks with the filter.Filter replacements are quite expensive, at about $80-$90 per filter and each filter lasting, in my area, about 4-5 months before it was so slow that a new one was required even though we didn't hit the 6 months (it's very possible we hit the gallon limit though).My number 1 problem is durability. After about a year and change (going into my 4th filter) the filter replacement process felt weird, as if something was wrong inside, but it worked. Then with the next filter replacement it stopped working entirely. The valve inside had clearly broke and with a new cartridge installed no water flowed through, instead it built up a huge amount of pressure and sprayed water all over the place when I removed the filter cartridge to reinstall it. I put the old unit back in to see if the new cartridge I got was a lemon -- it wasn't, because the old cartridge didn't work either.So after under 1.5 years and about $400ish dollars invested, my filter is broken and I'm still missing my 3m Filtrete which I got this to replace. That filter cheaper, worked better, and lasted much longer.
