Sediment in drinking water on its own isnt particularly hearmful to humans or pets but it can be an indication of lead or iron contamination which can cause serious health issues. If you suspect there is lead in your pipes get your water tested. Sediment filters help protect other appliances and posessions from the harmful effets of particles which can cause staining and spots on clothes, sinks, toilets and more and wear and deterioration on pipes and appliances If other filtration mediums are already in place in your home, sediment filters as a first layer of defense can increase the lifetime of your other filters by reducing the number of particles and contaminants that would otherwise wear on those other filters.
