Omnipure Q5640 Replacement Filter Cartridge

The Omnipure Q5640 Replacement Filter Cartridge is a carbon filter that effectively removes impurities and improves the taste of water. However, it should be noted that this filter does not significantly reduce Total Dissolved Solids (TDS), which are salts or ions that can pass through regular filters. To reduce TDS, additional methods such as DI media, reverse osmosis, or distillation are required. This filter cartridge is not a direct replacement for a Dupure pre/post filter and requires an adapter due to the special thread on the Dupure filter. It is important to ensure proper compatibility before purchasing. In terms of performance, some customers have reported that the filter clogs up quickly, which may require more frequent replacements. Additionally, there have been instances of leaking water immediately after installation, resulting in the need for returning the product. However, other customers have found the installation process to be easy and reported that the filter works well, providing clear and clean water at a faster flow rate. Overall, the Omnipure Q5640 Replacement Filter Cartridge has received mixed reviews. While some users have experienced issues with clogging and leaking, others have found it to be a perfect replacement for their specific filter system. It is important to note that some customers have reported that the water is still coming out cloudy even after running for 30 minutes, while others have mentioned that it is a temporary issue due to tiny air bubbles that will eventually dissipate.
