Do refrigerator water filters really work?

Clear water

“Do refrigerator water filters really work?” consumers often ask, with the hope of making sure whether the tools they bought are effective at removing contaminants from tap water or not.

This is natural, especially since most refrigerator water filters don’t come cheap - costing buyers at least $120 per year, an possible economic burden for ordinary American families.

As an industry professional, I can tell you that “Refrigerator water filters certainly work, as long as yours are acceptable products.” In the following part of this post, I’d like to explain as detailedly as possible to you why I hold the opinion.

Above all, let’s have a look at what makes up most refrigerator water filters on the market.

Several years of survey shows that most refrigerator water filters contain activated carbon inside of them. This substance works like a magnet, attracting contaminants and trapping particles in tap water. After the absorption process, the water would be cleaner and free from pollution.

The main disadvantage is that they can eventually be clogged up with impurities and have to be replaced. That means there’s an ongoing (and sometimes considerable) cost.

To ensure the safety of your drinking water, I recommend you to change your refrigerator water filter every six months or 200-300 gallons of water.

It should be especially pointed out is that no refrigerator water filters are perfect. Certain types of refrigerator water filters remove specific contaminants, so make sure to choose one that will remove the contaminants that are common in your local tap water.

Most refrigerator water filters offer little protection against the following:

Arsenic

Beryllium

Chromium

Fluoride

Nickel

Sulfates

Barium

Cadmium

Copper

Mercury

Selenium

Thallium

Depending on where you live, these heavy metals and inorganic compounds might not even be present in your tap water. However, if they are, you might consider specialized refrigerator water filters in view of your and your family’s health.

Now that you have the facts about refrigerator water filters, it’s time to make a decision.

To save money without sacrificing quality, I highly recommend you to purchase the NSF-certified Glacial Pure refrigerator water filters.

These tools’ activated carbon is made up with Sri Lankan coconut shell, a substance that is able to filter out 97% contaminants of tap water, including the unmanageable chlorine and fluoride.

If you’re considering about replacing refrigerator water filters, feel free to place a order on the shopping site of Glacial Pure. I believe you will have one of the best and most economical online shopping experience by trusting this brand!

How can you avoid having to buy expensive refrigerator water filters?

Tap water

Refrigerator water filter is a necessary household appliance for many of us. But it doesn’t always come cheap. Some cost as much as $60, meaning that you have to pay about $120 per year if you change your water filter every six months or every 200 - 300 gallons of water as advised.

To save money, you might have tried to find better-priced water filters online. But the problem is that you can’t figure out whether cheaper alternatives you found actually work.

Just in 2017, US Customs and Border Protection seized over 100,000 fake water filters entering the country. The counterfeits can do more harm than good - polluting the water that passes through them, a relevant study shows.

Fortunately, gpfilter.com now sells Whirlpool, Frigidaire and Kenmore refrigerator water filters at the lowest costs I have ever seen but without sacrificing quality.

On gpfilter.com, water filters are priced less than $20 per item, meaning that you can save about $80 a year if you place a order on the shopping site. The more you purchase, the cheaper the goods are.

You may start to suspect the quality of water filters on gpfilter.com now. Be reassured. All water filters on the platform have been tested and certified by the NSF. This proves that they are effective at removing contaminants from tap water.

Another very thing you need to note is that you don’t have to purchase water filters directly from your refrigerator manufacturers, especially since most of them sell water filters at higher prices.

Water filters are of great importance to your and your family’s health, so you must be really careful while choosing models.

Importance to Own the NSF Certified

There are many low-end manufacturers lying that their refrigerator water filters have been certified by the NSF.

More consumers are turning to refrigerator water filters nowadays in the light of the increasingly polluted water, creating a new industry worth of billions of dollars.

However, to make money, some refrigerator water filter manufactures lie that their fake products have been certified by the NSF. It has been proved that low-quality refrigerator water filters are not only unable to remove contaminants from water, but also potentially further pollute water thanks to the device’s unsafe raw materials.

Why are refrigerator water filters with (NSF) certification sought-after?

Although the federal government hasn’t required refrigerator water filter manufacturers to obtain NSF certification for their products, the Centers for Disease Control and Prevention and health departments in the US have suggested consumers to purchase refrigerator water filters certified by the NSF.

As a neutral third-party, the NSF’s certification has been recognized by 13 authoritative national-level or industrial organizations such as American National Standards Institutes (ANSI), Occupational Safety and Health Administration and the Standards Council of Canada.

The NSF is the designated cooperative partner of the World Health Organization (WHO) on promoting food and drinking water safety. Refrigerator water filters that are tested by the NSF and proved to reach the NSF standard will be authorized to use the NSF logo, which represents that:

1. As indicated in the manuals, the products have the ability to remove impurities from water;
2. Materials making up the products will not add any contaminants to water during the absorption process;
3. The products meet the design and production requirements;
4. The products have no structural and functional defects;
5. Advertisements, sample information and NSF certification shown on the products are true and accurate.

Meanwhile, the NSF requires refrigerator water filter manufactures to comply with its certification regulations if they want to use its certification logo on their products. These include accepting initial and periodic tests and evaluations, and even surprise inspections.

Once confirming its certification logo is misused or manufactures break rules, the NSF will take harsh punitive measures such as seizing, sealing, recalling, or even destroying unqualified refrigerator water filters, blacklisting the makers, informing consumers of the incidents, and canceling certification. The NSF safeguards the interests of all parties, regulating the behaviors of market players, consumers and makers, and supervise the implementation of policies and the authority of certification.

Water pollution

It’s estimated that roughly 80% of global sewage - mostly untreated - ends up being directly dumped to the environment, polluting rivers, lakes and sea.

This type of water pollution is very common in the world and is harming our health. Estimates show that the number of people dying from drinking unsafe water has surpassed those killed in wars or violences.

Our drinking water is very limited, especially since we can only get less than 1% of fresh water on this planet. If we don’t take action to protect it now, we will face grim water crisis by 2050, when the world’s demand for fresh water increases by a third.

You may not think water pollution is a serious problem when you still lead a comfortable life. But the worrying thing is that while most Americans are accessible to safe drinking water, various potentially harmful contaminants such as arsenic, copper and lead were found in many states in the US.

Fake refrigerator water filters are very common

In recent years, many cases of misusing NSF certification logo in the lucrative refrigerator water filter industry were reported. Illegal manufacturers made a tremendous number of fake refrigerator water filters to earn lots of money. In a move to address this problem, the NSF is taking legal action.

NSF certification involves several steps, including auditing manufacturers, testing products in the laboratory and conducting follow-up monitoring.

Using fake NSF-certified refrigerator water filters can further pollute your water and cause damages to your refrigerator.

Besides, fake refrigerator water filters might cause leakage and be less efficient at removing contaminants due to its low-quality raw materials.

If you can’t tell if a refrigerator water filter has NSF certification or not, you can check it out on the official website of the NSF.
