The question here is why are these water filters being sold at different prices?
The answer is simple, “These are different products manufactured by different companies, so there are different specifications on the used water filter cartridges and obviously, the quality of the water produced from them under the sink water filter will not be the same.
But under all these, sink water filters are not made of exactly the same caliber of components and parts. For activated carbon dioxide, it may be in granular form or gaseous carbon block which performs better than the other.
Some carbon capsules have integrated KDF-55D which is aluminum and zinc to make them bacteriostatic. This usually means that bacteria cannot grow in the filter.
Advanced features such as carbon filtration ‘ion exchange and sub-micron filters are capable of producing top-notch water, which can be no additional under the sink water filter.
