Including filter system and high-performance Perchlorate filter.
Perchlorate is a highly soluble salt that can enter drinking water when it moves from industrial or environmental sources into rivers, aquifers, or wells. Because it dissolves so readily, simple sediment filters or standard carbon cartridges often won’t remove it completely. Perchlorate and related names may not change the taste, smell, or appearance of water, so testing is the only reliable way to know if it’s present in your Cox supply. If you’re concerned, the aim is steady reduction at every tap in the house, not just at a single sink.
Even when your water looks crystal clear in Cox, trace contaminants such as perchlorate can be present and may fluctuate over time. Homeowners typically begin investigating after seeing a lab result or water quality report, or simply from wanting greater peace of mind for cooking, bathing, and laundry. A whole-house system means you don’t have to juggle pitchers or multiple point-of-use units, and the correct design is based on perchlorate’s chemistry and the most effective way to remove it.
The single filter type most often recommended for perchlorate is a properly engineered reverse osmosis (RO) membrane. RO separates water from dissolved ions like perchlorate across a semi-permeable membrane, rather than relying on loose media to trap the contaminant, making it a reliable choice for substances that remain dissolved. When used for whole-house protection, an RO membrane is installed with appropriate prefiltration to protect the membrane and maintain consistent performance for Cox homeowners.
A whole-house RO system treats water before it reaches bathrooms, laundry, and the kitchen, delivering consistent perchlorate reduction throughout your Cox home. Prefilters remove sediment and other material that could shorten membrane life, while the RO membrane does the primary reduction; many homeowners add post-treatment to improve taste and overall water quality after RO. Mr. Pure Water can help size and configure a whole-house RO system to match your household’s water conditions and daily demand.
