Huining 4PCS Fluoride and Arsenic Water Filter Replacement for Purification System - Gravity Filter for Travel and Bucket Filtration

Awesome

I was lured in by the lower price to replace some of my Doulton 10" Super Sterasyl filters in my gravity water system. I am very skeptical these filter to the submicron level that Doulton is known for. Where my Doulton filters would always have a very slow "drip..............drip.................drip" from each, these Huinings are "dripdripdripdrip", almost approaching a steady stream when the upper chamber is full. These filled the bottom bucket full in only a couple hours whereas my Doulton's easily took overnight to do the same.I don't think water can pass that quickly through ceramic and charcoal and still have the protection that the Doulton's do. Yes, these certainly look like the same size and shape candles, but until I see some verifiable third-party water testing results for them, I am assuming these are less effective, cheaper knockoffs, not true "OEM" quality. If you're just looking to improve the taste of your water, these may be fine for that purpose. But if you are relying on these to remove bacteria, cysts, and other contaminants, I have my doubts they are doing so as well as the certified and trusted filters they are copying.

These filters are of good quality! I bought them to filter used isopropyl alcohol from my resin 3d printing projects, but these will not work with alcohol. I got a 4 pack and installed all 4 in a bucket that would gravity feed the alcohol through the filters into another bucket. The first attempt i discovered a broken threaded stud had occurred on one of the filters and i wasnt sure if it was already broken or if the rubber gasket had expanded due to the alcohol which could have caused a hydraulic pressure crack at the threaded outlet, or if the plastic at the base of these filters is just not compatible with the alcohol. So i made another attempt with the remaining 3 i had left and checked them thoroughly for damaged threaded outlets before assembly and they all looked fine. Came in today and another one of the filters broke where the outlet meets the base again, same failure as before. So, these im guessing are just not suitable for alcohol filtration. Which they arent advertised that way so i have no gripes! This was merely a test run to see if they’d work and as far as the successful filtered alcohol that went through before they broke they worked great. The filtered alcohol was clean as new, but these are definitely intended to be water filters. Just though i’d share my results so that anyone else who is thinking of using these particular filters will know ahead of time that they dont work for alcohol. The filters themselves are of very high quality though and i would recommend them for WATER filtration only for sure!

I bought 5 of these. I soaked the filter as instructed. The water is literally filtering through one drop at a time. At this rate it will take a year to fill a 3 gallon bucket. My water is very clean well water and I previously used the Zero water filter for quite some time but wanted to switch it up to a larger container. This filter doesn't work at all for me.That was my initial review. I continued to use the filter. It is slow. I built a system with a 3 gallon square container on top of a 5 gallon rectangular bucket on the bottom with a flip open spigot and with the filter between the two buckets. Although the filter is slow, I filled the top container until my bottom container was full which took a couple of days. I usually only use 1-2 gallons a day for two persons and 2 medium dogs. I now had plenty of water. Each evening, I take my faucet sprayer and fill the top bucket accordingly and keep my bottom bucket somewhat full. I am giving the filter a 5 star due to it works as described and I will continue to purchase and use these filters.

Just like the ones that came with the Water Filter.Haven't used them just yet saving them for when I need them.Don't really if the do what they say they do and how long they would last. 6000 gallons in a year.Seems all of them need to be replaced once a year and don't last for the 6000 gallons.

Buena calidad

Fits our ProOne gravity fed filter, we've used these filters inside it for 3 months now with no issues. They are a lifesaver, so much more affordable than other filters out there. We have been drinking filtered rain water out of it and it's been wonderful. Definitely run water through at least two times before drinking, though.

Parts were missing ( faucets ) missing from one of sets. Now I'm supposed to return them wait for them to be re-shiped. Just ship the faucets that were supposed to be shipped in the order.

Je ne conseille pas ce produit. Les cartouches donnent un mauvais goût à l'eau.

J'ai testé quelques filtres et c'est le seul qui filtre réellement à moins de 0.3 micron. Très content de cet achat.

Ne fonctionne pas. Ne filtre pas.

très bien emballé livraison rapide parfait
