Best MWF Water Filter Reviews

1. General Electric MWF Water Filter

General Electric has been producing some of the best home appliances in the market. And, GE MWF Refrigerator Water Filter is made to meet the same standards.. As such, they only offer high-quality water filters with high-end functionalities.

This product is a premium smart water filter featuring an innovative way of eliminating contaminants. The water filter removes particles that are invisible to the naked eye, such as chlorine-resistant cysts, asbestos, lead, and some volatile organic compounds (VOCs).

Plus, it can remove up to 98 percent of five pharmaceuticals, such as progesterone and ibuprofen. Notably, the filtration mechanisms do not affect the taste of the water at all. It tastes as fresh as spring water from the mountains!

I love how easy it is to install this twist-and-lock GE MWF water filter. The design fits well with many GE refrigerator models and units. Also, I do not need any special tools to install them in my fridge correctly. The water filter securely locks into place.

Its sides are also quite solid and sturdy, which shows GE’s attention to quality. That means it can withstand the strongest grip without deforming the unit.

Each water filter unit will last around six months. It may have a shorter lifespan for families that consume water more than the recommended capacity.

The premium performance also means a premium price tag. I was hesitant to purchase it at first due to its price. Some users may also have issues with it, especially if they do not have a GE refrigerator.
  • Designed to work well with select models of GE refrigerators
  • Filters many small particles and pharmaceuticals
  • Does not affect the water taste
  • Quick and easy to install with the twist and lock design

The PURELINE MWF Water Filter is one of the most popular generic filters in the market. It fits most refrigerator brands and models. For anyone looking for the best GE MWF water filter, this is a great option.

It features a unique triple action filtration technology that utilizes advanced carbon blocks. The water passes through a layer of active coconut carbon that effectively removes any particles through mechanical filtration. That means any tiny debris or sediments are eliminated right on the first stage of filtration.

Then, it goes through two stages of ionization filtration for better water quality: physical adsorption and electro-kinetic adsorption. These stages ensure that any chemicals left from the first stage will be gone.

The MWF water filter cartridge is certified by IAPMO, WQA, and NSF. That means it is guaranteed to remove most heavy metals and contaminants such as mercury, VOC, etc. Additionally, it significantly reduces copper, lindane, cadmium, chromium, and other major pollutants.

I specifically love that it removes about 99% of chlorine to provide fresh-tasting water. Many localities use chlorine as a way to decontaminate water. However, it is known to cause various illnesses, such as heart disease and cancer.

What about bacteria, viruses, and other microorganisms? The water filter thoroughly filters these contaminants through the adsorption process mentioned above.

While it is marketed as a generic water filter, it does not fit all GE refrigerators’ models. Thus, it is essential to consult with the product notes or the distributor to ensure the perfect fit.

It also meets the NSF/ANSI 372 standard, ensuring the water coming out of the filter is always lead-free. The water filtering mechanism is also awarded over 100 patents from all over the world. However, it does not filter out pharmaceuticals.

Did I mention that it perfectly fits certain models of GE refrigerators? That’s right! It is a great alternative to the more expensive GE MWF filters. Besides, this device is compatible with other brands such as KitchenAid and Kenmore.

The company also included its MWF water filters into its Water4Smile Program. Their project includes various activities that provide clean water, access to clinics, and other benefits to many families in the region. The brand promises to provide one child with one day of clean water with a single water filter pack purchase.

I like that its filtration accuracy is one micron. That means the filter will remove many tiny impurities. However, it results in a relatively slow flow rate compared to other filtration systems.

It is compatible with other non-GE refrigerators; just confirm with the company documentation first before purchasing.

Just like the original, it can handle the same capacity, which is about 300 gallons (1,135 liters) of drinking water. As such, it lasts almost similarly well at six months of average use.

It is NSF/ANSI 42 certified, which proves effective use in removing bad taste, odor, and color for more refreshing drinking water. However, unlike the OEM-made version, it does not have an NSF/ANSI 52 and 43 certifications. That means it may not entirely remove lead, chlorine cysts, and similar water contaminants.

I would highly suggest looking up reports about the quality of your local water supply. Most cities have good water systems. That means this alternative to the GE water filter will be enough to keep drinking water clean and safe.

Luckily, this model can rid of bacteria and other pathogens that may cause illnesses. Hence, it can make sure that drinking water is safe for your family.

What to Look for When Buying MWF Water Filter

There can be heavy metals, micro-organisms, and particles, or other major contaminants found in water. And picking powerful products can help eliminate around 90 to 99 percent of them, depending on different filtration systems.

Most MWF water filters adopt advanced active-coconut-carbon blocks to keep impurities from passing through. These devices feature small-sized micropores that remove all sediments and metals. They should also purify your water to rid of the weird odor and result in a fresh taste.

Certification – The filters with NSF/ANSI 42 certificate can reduce impurities such as chlorine. As a result, the drinking water will taste and smell fresh, without chemical and other unpleasant odors.

Filter life – Most MWF filters can function smoothly for six months then require replacement. Such a period can translate into 200 or 300 gallons of fresh drinking water, depending on the flow rate of each product. Thus, you should take the durable and functional construction that lasts at least through such a duration.
