If you have ever replaced the water filter in the refrigerator, you will know that they are not cheap. Some cost as much as $60, which means that if you follow the instructions to replace the refrigerator water filter every six months, this is indeed a significant expense.

Therefore, it is not surprising that some consumers are trying to find cheaper filters online. The problem is that you don’t know if there are many cheap alternatives that really work.

That's because at least some of them are counterfeit water filters. They are sold online, and some are sold under the refrigerator brand, but they are actually fakes. Last year alone, the US Customs and Border Protection seized more than 100,000 counterfeit water filters in the country. According to a recent industry-sponsored study, counterfeit filters can contaminate the water flowing through them and do more harm than good.

Therefore, "Consumer Report" believes that these counterfeit products may have health effects.

CR’s Chief Scientific Officer James Dickerson said: “You should follow the manufacturer’s guidelines and buy filters from industry-proven sources whenever possible.”

"Consumer Report" aims to investigate whether consumers can obtain after-sale filters of the same quality and protection level at a lower price. There are not many such manufacturers.

Here, I am happy to tell you that because you have found purerop, our filters have been tested and certified by NSF International and meet strict public health protection standards. This is a quality assurance for consumers. The price of this filter is about 20% lower than that of the refrigerator manufacturer's filter. It can be used to reduce chlorine and odors and target lead and volatile organic compounds. Not only that, purerdrop is a filter that can match the high standards achieved by most refrigerator brand filters.
