Pentair Pentek CBC-10 Under-the-Counter Carbon Water Filter, 10-Inch, Carbon Block Cartridge with Bonded Powered Activated Carbon (PAC) Filter, 2.5” x 10”, 0.5 Micron

Why did you pick this product vs others?: This is a direct brand replacement. I believe it is the best value filter you can get. It replaced our last filter we have been using for a year, way beyond it's volume and expiration period and still removes most of that reservoir water smell from the tap. This replacement along with a Brita filter pitcher for a fringe improvement gives us near snow melt well water quality you get in the high mountains in the spring. Our tap water isn't anywhere near the hard water you get from a southern California tap but has a bit of lake water smell, occasional mold fungus that immediately starts growing on the toilet bowl with a lot of new PVC pipe leaching into it, while on it's way here. Following any fungus blasts some kind of fungicide usually follows. Needless to say, a chemical reducing .5 micron biological safe water filter is a must here. This is the one that has led the pack for us.

This Pentek filter works great. I use an APEC RO system under the sink. It's a good RO system but the APEC system's second and third stages come with 10 micron filters and the water still has a taste. I replaced the third stage with this Pentek .5 micron and the water is noticeably cleaner tasting. I seriously haven't found better tasting water. However, I did notice a CA Prop. 65 Warning on the label: "This product contains chemicals known to the state of CA to cause cancer or birth defects or other reproductive harm." and also that it's "Made in China". Between the two it makes me nervous. And the label says "Not performance tested or certified by NSF" yet also says "This cartridge is tested and certified by NSF International under NAF/ANSI standard 42 for material requirement only".. SO...Which is it? This is not enough to knock a star off the rating but I do lose that peace of mind. I wish I knew what it was that Prop 65 was referring to, the carbon? plastic? Is it NSF tested or certified? I don't see other filters with disclaimers so why the caveat emptor for this one?

Good filter.

My main point of hatred toward these was the fact that they still had the Californian cancerous ingredients. Well- I called the customer service and asked and asked until I received an adequate explanation. Essentially the plastic is fine. It meets anyone's reasonable expectation for a safe product that touches water you drink. The point of issue has to do with the carbon used to filter the water. The testing required to check these hinks of carbon for heavy metals is expensive. So they don't do it. But because of that they can't guarantee there isnt any. Hence the warning label. They say it's likely there isn't an issue but they can't say as much unless the testing is done. Otherwise the filter works fine. Taste is fine.

I use this for brewing beer and it is great to take whatever is in my water out before I put in in my kettle for brewing.

Cuts water flow by 70% ! Open facet and it just trickes out . Very restrictive filter

I got this to replace an old 7-stage cartridge for my under-sink filter. While it would take a miracle to make my municipal river-water tap water taste great, this filter does a fine job of making it drinkable and refreshing. My house still has some galvanized pipes that are rusty and impart noticeable odor and taste in my water. This filter does an effective job at removing this. Also my city makes the water smell like a swimming pool. That smell is 100% gone now. I bought this one over similarly-priced granulated carbon filters at Lowes for that extra level of protection offered by block carbon. It is built very sturdily and has a good weight to it. The micron filter on the outside feels high quality. Carbon block is a very basic but effective filtering method that won't remove everything but does a good job of general improvements to municipal crap water. I would recommend if you're on a budget and want to upgrade from Brita filters or need to swap out an old granulated carbon filter. I feel like the multi-stage filters do a better job and get out more metals and chemicals, but they cost 4x more than carbon and don't last long. I'm comfortable enough with this filter as a safety measure for better water.

These filters perform well. Easy to install.

Conforme et facile d’installation

Bon produit exactement comme chez le détaillant

High quality and true dense 0.5 microns. The water from my well is pretty good and odorless, but has a color from tanins (I had already tested iron filters). In the pictures, the first 2 cups on the right were 2 different carbon filters of 5 microns and different brands. Then I tested this one, and bingo, the cup on the left was crystal clear. Even the weight of the filter is a lot heavier than the other filters, and while the other filters don't restrict flow, this one does so, I don't think it works high volume applications but for drinking water it's awesome.

Washer seemed to.thick otherwise very satisfied R.M

Inodore e perfetta.
