Water Sentinel WSG-1 Replacement Fridge Filter

I was checking out these filters to replace the more expensive GE filters. According to Water Sentinel themselves, these filters are certified against ANSI/NSF Standard 42, and only Standard 42. That standard is soley for aesthetics; that is, the filter removes chlorine that makes the water taste bad. The GE filters are certified against ANSI/NSF Standards 42 and 53. Standard 53 is for the reduction of lead, mercury, Giardia and other cysts, asbestos, and many other chemicals. The Water Sentinel filters do not claim that they are certified to remove these items. So, although the water tastes better than tap water, it may not be any safer than tap water. If you're buying filters only to improve the taste of the water, these are definitely less expensive than the GE filters. If you're buying filters to improve the safety and quality of the water, you may wish to look at other filters.

From the ANSI website:

NSF/ANSI Standard 42: Drinking Water Treatment Units Aesthetic Effects

Overview: This standard covers point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste and odor, and particulates) that may be present in public or private drinking water.

NSF/ANSI Standard 53: Drinking Water Treatment Units Health Effects

Overview: Standard 53 addresses point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.

I almost bought the Brita brand filter again after reading about all the people experiencing leak problems, but I couldn't resist the savings. I've used the original GE MWF filter in my GE fridge, then switched to the Brita brand and have replaced several of those. I just recently found the WaterSentinal brand and it's about a third of the cost of the Brita. I went to install it in my fridge and like many others my fridge just sprayed water everywhere. It screwed in all the way like it was supposed to, but wouldn't stay sealed. When I opened the box I noticed another o-ring in there with a note that stated if it leaked then use this o-ring, so I quickly swapped out the o-ring and I was in business. I ran it for 5 minutes as they say to clear all the crud out, and I'm pleased to say that this filter works just as well as either the GE or Brita filter ever did. The flow is also noticeably faster too. Water and ice from this filter tastes the same, and I saved a bunch of cash! I'll be buying again for sure.

Installation was a cinch. Does what it claims. Cheaper than the GE filter. However, I think it's overpriced for what it is, but I guess they tailor their $ to GE's cost which is just ridiculous.

I purchased this for my GE refrig and it does NOT work properly. No matter how many times I tried to install it, it continuously sprays water inside the refrigerator. I will say, however that the Water Sentinel is a good company and admitted that they have had more than one complaint about it not working on some GEs. They are sending out a new one that "should work" at no cost to me even though I didn't order directly from them. So -just be aware that you may get one that is defective or just not compatible.

If you are considering to purchase the Water Sentinel WSG-1 as a OEM replacement filter for the GE-MWF, be aware of the hidden-fact that, although the (WSG-1) housing cartridge has been designed to fit your GE Refrigerator, the flaw with the (WSG-1) is the small 'constricted-size' of the water port that was designed for water to flow through this filter. The water port on the GE MWF is about 1/2" in diameter which is sufficient in size to allow water to pass through the filter freely & unrestricted.

When I removed the packaging and plastic water port cap seal from the (WSG-1) I discovered that the water-port-hole designed for this filter was not even 1/4" in diameter (less than half of the GE-MWF) and extremely small in comparison to the water-port-diameter of the GE-MWF.

In conclusion, the engineers that designed the GE-MWF obviously decided that a minimum water-port-size of 1/2" was needed for this filter to function properly. In my opinion, whoever designed engineered the Water Sentinel (WSG-1) filter cartridge to replace the GE-MWF, clearly 'shorted-sighted' the OEM guidelines for the diameter of the GW-MWF water-port, and in that regard is the reason why I returned the Water Sentinel WSG-1 to Amazon for a refund.

Unfortunately for the consumer, Brita & Aguafresh have discontinued production of their GE-MWF replacement filters, which consequently has given GE an outrageously ($ high-priced $) monopoly on their replacement filters for their GE Refrigerators.

Activated Carbon is cheap, and so is the plastic filter housing unit. Realistically, this filter could be sold for about the same price as an oil filter for your car and still return a profit. The GE in this case...'G' is for Greed, and 'E' is for the Economic consumer shaft perpetrated by the multinational corporations.
