Purerite water filter ‘unlikely to be an effective option’
Posted On August 7, 2021
The US Food and Drug Administration (FDA) is expected to issue its final rules for the use of purerite filters in water filters later this year.
While it has long been widely accepted that a purerite filter is the best option, critics say the FDA’s final rule could make it even more expensive.
Purerite filters are made by combining two or more chemicals in a water treatment plant to remove some of the water molecules.
They are often used to remove heavy metals from water.
However, many critics say they can also cause harm to fish.
The FDA has not set a deadline for when the rule will be released.
This is because the final FDA draft rules are still being finalised, and they will likely take a couple of months to be finalized.
In the meantime, there are currently more than 7.5 million water filters in the US, with about 100 million of them being sold each year, according to the US Department of Health and Human Services.
The majority of those are for personal use.
In addition to protecting against disease, water filtration also has health benefits, according the FDA.
According to the agency, using filters improves the quality of water, reducing the amount of dissolved oxygen in the water, and helping to keep fish healthier.
“Purerite filters have been shown to remove dissolved oxygen, which is one of the most important pollutants to protect fish,” Dr Michael Siegel, an expert on water filTration from the University of New Hampshire, told Al Jazeera.
“The EPA is not recommending that purerite filtrations be used in drinking water for human consumption.”
