PFAS and Health Canada guidelines: why RO is the home fix
Updated Canadian drinking-water objectives tightened PFAS limits. Certified reverse osmosis remains the most practical point-of-use solution.
Why PFAS is in the news
Per- and polyfluoroalkyl substances ("forever chemicals") persist in the environment. Health Canada has tightened recommended drinking-water objectives, raising awareness for homeowners near airports, industry and some firefighting foam sites.
What RO removes
Certified reverse osmosis systems reduce PFAS, lead, arsenic, nitrates and dissolved solids at the kitchen tap. Look for NSF/ANSI certifications relevant to contaminant reduction and keep pre-filters on schedule.
Whole-home vs under-sink
Point-of-use RO is the usual PFAS strategy for drinking and cooking water. Whole-home carbon helps taste and chlorine but is not a substitute for certified RO when PFAS is the concern.
