Are there any disadvantages to the refrigerator water filter

We know that nearly 300 million Americans get their drinking water from the community water system managed by the EPA. These water supply systems must comply with the "Safe Drinking Water Act" and purification standards established by the EPA, which are designed to remove 80 different pollutants from water sources, including E. coli, chlorine, arsenic and lead.

According to the Centers for Disease Control and Prevention, more than 30 million Americans get sick every year from drinking contaminated water. Although water treatment plants are required by law to remove some pollutants from water sources, they usually leave behind many particles and bacteria for our drinking.

Therefore, kenmore refrigerator filter 9030 have become commonplace in many households because they are designed to filter out any remaining contaminants, such as lead or rust, before we drink the water. The ability of these filters to purify water is measured in microns; the lower the micron level, the greater the ability of the filter to capture small pollutants.

Refrigerator contamination is not necessarily a filter problem

If you find that the water in the refrigerator is contaminated, it may not be a filter problem. According to a 2013 study by the National Sanitation Foundation of the United States, the easiest place to breed bacteria in the kitchen is the refrigerator water dispenser. Studies have found that most of these dispensers are coated with "relevant levels" of mold and yeast.

The dispenser can also pick up airborne particles that may come from rotten food in the kitchen. When your water is poured through a drinking fountain, it will absorb these pollutants and bacteria. Even if your refrigerator filter is done well enough, if the water re-enters the particles on the water dispenser, anyone who drinks water is at risk of being contaminated.

Refrigerator filters cannot remove all contaminants

Refrigerator water filters usually use carbon, with an average grade of 20 microns, which means they mainly remove contaminants that affect taste and smell. Do not rely on the refrigerator water filter to remove all particles and bacteria that may be harmful to drinkers.

The number one risk of drinking water purified with refrigerator water filters is that refrigerator filters usually cannot remove all contaminants in the water. Studies have shown that microorganisms such as salmonella and coliform often pass through water filters, and these pollutants can seriously damage your health.

Most refrigerator water filters are not designed to filter out such harmful contaminants, because the EPA should purify the water before it enters the refrigerator. Aquatic bacteria need fungi and water to survive, making your refrigerator water filter an ideal place for them to multiply. Even if drinking water is properly purified before distribution, studies have shown that trace amounts of drugs, lead, and parasites (such as chlorine-resistant cysts) are usually not filtered out. So the general refrigerator water filter may not protect you.

The pur 4396710 is not permanent and needs to be replaced regularly

When refrigerator filters remove the contaminants and particles they can remove, they become clogged with whatever they manage to remove from the water. These filters need to be replaced approximately every six months, and failure to do so may have catastrophic effects. If you don’t change the filter, you may end up consuming harmful bacteria, chemicals, and particles every time you take a glass of water from the refrigerator.

When the refrigerator filter remains the same, you will usually find E. coli and fecal coliforms in your water. These bacteria can cause serious damage to your health. Some refrigerators do not have an indicator light to let you know that the filter needs to be replaced, and the filter itself is usually invisible, so it is easy to forget to keep up with the necessary maintenance. Be sure to set yourself some reminders to replace the refrigerator water filter, otherwise you may come into contact with dangerously contaminated water.


Although the refrigerator filter is not a panacea, it is essential. With the continuous improvement of refrigerator filter manufacturers, Morefilter's filter 4396841 can remove 97% of pollutants, which has greatly met the needs of customers.
