Including filter system and high-performance Perchlorate filter.
Perchlorate is a very soluble salt that can enter drinking water when it moves from industrial or environmental sources into waterways. Because it dissolves so readily, simple sediment filters or basic carbon units often won’t remove it reliably. Perchlorate may not change your water’s taste, smell, or appearance, so testing is the only reliable way to know if it’s present in your Portland supply. If you’re concerned, the aim should be steady reduction at every tap in your house, not just treating a single faucet.
Even when tap water looks crystal clear in Portland, small dissolved contaminants such as perchlorate can still be there and fluctuate over time. Homeowners typically start exploring options after seeing a lab result, reviewing a water report, or simply wanting greater peace of mind for cooking, bathing, and laundry. A whole-house system removes the hassle of multiple pitchers or point-of-use devices and delivers consistent protection across the home. The best systems are chosen based on perchlorate’s chemical behavior and how it can be most effectively removed.
The single filter type most often recommended for perchlorate is a properly designed reverse osmosis (RO) membrane. RO separates water from dissolved ions like perchlorate using a semi-permeable membrane rather than relying on loose media to trap contaminants, so it’s well suited to handle contaminants that stay dissolved. For whole-house use in Portland homes, RO systems are installed with the necessary prefiltration to protect the membrane and maintain steady performance over time.
A whole-house RO installation treats water before it reaches your Portland bathrooms, kitchen, and laundry, ensuring consistent reduction throughout the house. Prefilters remove sediment and other particles that could shorten membrane life, while the RO membrane reduces dissolved contaminants such as perchlorate; many homeowners add a post-treatment stage to refine taste and polish overall water quality. Mr. Pure Water can assess your Portland water and household needs to recommend the right whole-house RO configuration.
