Customers Feedback:

Looks at fits like the Original. My frig is a Thermador 48″ refrigerator using the Whirlpool designed water filtration system (old Whirlpool part #4396510). Was worried that the neck was a little shorter than the original but if you look closely the body of the filter it now has grooves in it that help the threads. Fit like a glove into my frig with no issues. Actually easier than I remembered it in the past with the original. Also, my water flow was dramatically increased which is great as it takes shorter time to fill your pitchers. And I like the fact that this good water filter for sink more things out than the original (as stated on packaging and website).

I tried to save money and bought several of the knock-off versions of this made in China. One of them busted my refrigerator. The other two made the water taste strange. This filter though was amazing. You just flush water through it, as per the directions, and you have 6 months of amazingly clean and fresh water to enjoy any time. They also have a nice subscription program you can join to save additional money and get continual replacements automatically, every 6 months. This is the original filter and will be probably more than others you find online (…it’s worth it though). Don’t get suckered into using the imitation ones. I have and learned.

Installation was a breeze! Popped the “T” valve into my cold water line (took 30 seconds) hung the filter (has screw hole location sticker included! No guessing with screw placement!) Installed the new spigot in the spare hole in my sink. Ran the water line from “T” to the “in” on the filter, then from the “out” of the filter to the spigot!

I live in an area that is considered to have a good municipal water supply and by all accounts it does. Even still, at this price I thought I would try this inline water filter to see if I could tell if there was any difference. Very easy to install without having to deal with a bulky tank. After running the faucet for 10 minutes I compared a glass of unfiltered water and filtered, the clarity was similar but slightly better than the municipal water and then I tasted it, OMG!!! Tasting between the two, it was shockingly noticeable that the municipal water had a chemical taste and the filtered glass was chemical free, I HAD NO IDEA…. The difference is now very noticeable in tasting coffee and cooking as well as drinking. I can highly recommend this product, highly…

Awesome water filter system. FYI, this is not an RO system. Very easy to install, water tastes great. Highly recommend the under kitchen sink water filter. Saves us time and money from going out to get water from Walmart or water station. Paid $109 for the system with free shipping. System filters out particles down to 0.5 micron, that is better than water from Walmart and water station. I believe Walmart water and station water only filter down to 1 micron size particles.

The faucet arrived shortly after I ordered it and it was well packaged. After reading the instructions I removed the purifier and included filter and adapters. The actual set up literally took me about 10 seconds. The attachment I needed for my faucet was already attached to the purifier and I didn’t need to use any plumber’s tape. After using it for several days this week there has been absolutely no leakage and the water tastes great. I especially like the flow of the water from the filter because it makes it quick and easy to fill the 52 ounce bottles I keep in the fridge. I previously was using a Pur filter and hated filling my bottles because it took forever to fill just one.

My previous plastic faucet filter cracked after about a year of use, and I went for a more durable stainless steel one (also just not a fan of plastic in general). Installation: Installation was very easy! I’m wouldn’t describe myself as “handy,” but even I was able to figure it out. The instructions that come in the box are very helpful and it includes pictures on what to do. The best faucet water filter only took me about 5 minutes to install, but I’m sure someone with a little more skill than myself would take them much less than that. Water: Tastes fantastic! I live in Southern California where the tap water isn’t winning any awards for taste, and this filter made the water taste great. Overall, I definitely recommend this product.

I was wondering what’s inside a water filter and the only way I can think of finding out initially when you look at the drawings and the size of packets it shows all the different layers of filters and things that are but now I’m looking at it I can see this dry one I can seal this up powder rolling about inside so am let’s open it the first thing I notice is this a gasket which is quite neat it’s got a little rubber o-ring for the steel the top it’s got with the collar coarse filter and it points to these slots now yes I suppose technically speaking that is a coarse filter let’s say I get a knife and open this is going to use a super industrial name for this and I’m going to cut towards myself in a menacing manner okay so here’s the fame filter inside which is justice an island mesh heat shield on.

And it’s a two-tier see little granules lake coloured granules and dark ones and guessing the dark ones have I got a tub here and then the output you’ve got these granules and then the output is just these slots the bottom without more nylon mesh are fused over them from inside and that’s it okay so let’s say take a look at this now these granules are a mixture of what they call ion exchange resin I believe and activated charcoal the activated charcoal tends to absorb impurities to a degree while the resin here is what they call ion exchange resin a belief and the point that I own exchange resin is it’s kind of preloaded with sodium and when other metals attach to it like magnesium or undesirable metals that melt there what they consider undesirable metals.

When an ion of the undesired metal attaches to it then liberates an ion of sodium instead replaced I’m not sure if that’s a good thing or not that it’s supposed to make the water softer which is the main feature of that thing so I’m wondering what will happen if I add water to this will actually swell up I’m going to put a mark in the side and then I’m going to add some water so just going to tap that down slightly put a mark on the side of the height of it add some water and see if it swells up I shall be back shortly several minutes of soaking later and it seems to have bulked out by almost 50% it’s notably sort of filled up and formed a sort of like that almost like not quite a non-newtonian fluid but when you disturb it you get that sort of like the water sort of sits.

On top but then when you pork it to em the stuff displaces up through it like sand I suppose really which is ultimately in a way, yeah sand is also used as a filtering agent but let’s get a bit of paper and I shall put a smear of this onto the paper and then I’ll draw what I see when I look through a microscope at it it’s a bit paper and I’m just going to a pinch of the stuff and just smear all over it yeah right microscope and a pen write the little layer that ion-exchange resin it’s very round it’s just little spheres and the charcoal is very sharp and ragged-looking obviously designed interlocked together for the filtration, okay so I shall draw that the ionic exchange resin the white stuff furless.

Of creamy coloured stuff is just basically spheres randomly sized spheres and whereas the charcoal is just very jagged pieces like that obviously designed to sort of form a closed knitting interlock it’s presumably just crushed from a solid block and again that it’s like really small bits and really big bits so a whole random arrangement now I noticed when I added the watch person tapped it down that the by default the carbon seems to set low if this is the dish the carbon seems to settle out at the bottom preferentially with the spheres of the resin sitting on top you still get dispersion of the black through the subway but it does form distinct layers so I’m guessing though in this filter when it’s actually filled as the liquid the charcoal will tend to precipitate down to the bottom.

And will go through as a multiple series of layers presumably with the charcoal being so ragged and close-knit that it does take quite a modest time for the liquid to actually travel through and a lot of the solid impurities will just get trapped and that would also suggest that if you wanted to clean one of these out you can’t really reload the carbon or the ion exchange material but if you tapped it to loosen it and then washed it you could actually maybe sort of getting if you’re just looking to remove large particulate then you could probably clean that out and reuse it to a degree then yes that was quite interesting and well worth doing.

How to Install a Water Filter Under the Sink?

Video Transcript:

I love this place it feels so 50s Liz I love it no far off it was built in the thirties watch your step on the gate you have a new baby we do it well she says bout a year old now congratulations thank you look at this place it’s like a museum so retro is this thing still run fine, yeah yeah it came with the house we use it every day it has some quirks we had to put a thermometer inside so we know what temperature it is while we’re cooking we’re really excited to restore that someday though we all have a few Kirk’s who want to get older and look at this thing matches perfectly yep this was the faucet that was the rage in the post-war era at had hot and cold with a spout but it had this feature it had the spray hose.

That had a soap additive here so you can hit the button and wash the dishes the next newest convenience but this is not original no well after the baby we wanted to make sure that we were getting good water quality so we put this snap-on filter on there but this is the problem we have now oh boy now that’s not any okay all right so what this is is a little filter cartridge right here and it’s relatively small and so in normal mode, the water misses the filter completely and then you turn a bypass and you push the water through but you can see it’s relatively small flow because the filter itself is small what I’m gonna propose is actually let’s get rid of that put a high level of filtration down out of sight.

You have to think about it don’t to see it and make this thing go back to what it looked like when it was first installed well all right here is the new filtration unit we’ll sit down under the sink so there’s a little indicator system here you see it’s red right here but as I put the cartridge in seeing the blue indicators come across and what happens is over time as it gets clogged as they work these blue will disappear and when it gets to zero you’ll know it’s time to change it that’s pretty cool the two cars are pretty interesting – I brought a cutaway this is a carbon composite membrane inside here and actually it’s a pipe in a pipe system the water comes in through this outer pipe comes down inside the filter through this outer surface area and works its way through to the centre where it then leaves through this inner pipe now it’ll also remove the regular stuff Felixdirt sediment.

Russ but it also will do heavy metals like lead and mercury and even pesticides and pharmaceuticals that are great and with this much surface here you can get up to about a year of coverage without having to change the good cartridges we’ve been having to change the filter on this one every two or three months right well let’s get started but turn off the water I only have to shut off the cold cuz that’s all we’re working on okay so let’s just open up the cold and take the pressure off now let’s say goodbye to this guy’s two buttons to release it that goes away somewhere I just got to get rid of this aerator get rid of the old adapter.

I’ll give you that a new aerator let’s get a little to this old tape away make it look pretty okay now let’s put on a new aerator that looks better already alright so here’s the backside of the unit and it comes as a kit with all the tubing connections and the adapters you might need for most installations and look at this it even has a diagram in the back to reduce the chances that you miss pipe it there’s a symbol for the cold water shut off and here’s the feed going in coming out of the filter it goes up to the cold water side of the faucet right there all right let’s break.

These connections and get going this should be a little bit of water here this is a compression connection I just have to loosen it and then going to replace it with a new supply okay now a similar adapter on the other side there’s a couple of piece of black tubing just grab them thank you alright now these connections are pretty interesting to me this is actually a push connection if I push it up and in it locks in place and it’s watertight all right so I’m going to leave these tubes long because it allows for service in the future and good that was a made so now I’m gonna turn the water.

Back on before I push it into place right I have initialized your system which means I ran it for five minutes and that flushes the carbon and activates it let it sit for 10 and then ran it for three more so it’s now ready for your test okay I’m gonna try well it tastes great that’s good news yeah and it looks so much better too oh great I wish you many years of clean water thank you thanks for watching this whole house has got a video for just about every home improvement project so be sure to check out the others and if you’d like we can see click on the subscribe button make sure that you get our newest videos writing your feed.
