3M CS-52
3M CS-52
$18.99 NSF 42
The CS-52 filter is an alternative filter for the Bosch 640565. The CS-52 is made by 3M Purification while the Bosch 640565 is made by Cuno. However, because Cuno is a 3M Purification brand, it is safe to assume these filters are similar in quality. Even though this filter only carries NSF 42 certification, many customers have been quite happy with it. Several customers have also claimed that this filter is a bit easier to change, which may be due to its ergonomic design at the bottom of the filter.

Aquarius AWF-640565 is a quality, compatible filter for the 3M CS-52 / Bosch EVOLFLTR10 filter. Unlike other compatible filters, the Aquarius filter is tested and certified by WQA (Water Quality Association) to meet NSF/ANSI Standard 42 for material requirements, so you can be assured of its quality. Independent laboratory testing is conducted regularly and the Aquarius filter is proven to perform just as well or better than the OEM filter. We would highly recommend this alternative filter.
