Environmental Health Dossier: Air & Tap Water in Lakewood

Atmospheric fine particulate matter (PM2.5) and municipal drinking water contaminants represent the two primary involuntary daily exposures in any household. While HEPA filtration purifies indoor air, municipal tap water often contains invisible halogenated byproducts, heavy metals, or PFAS forever chemicals.

Atmospheric Exposure
Inhalation Risk

Lakewood holds a historical Clean Air Score of 85.2/100. High PM2.5 requires True HEPA (H13) physical media filters without electronic ozone generation.

Hydrological Exposure
Ingestion Risk

Municipal utility compliance focuses on legal limits, not health guidelines. Verified solid-carbon or Reverse Osmosis filters target lead, chlorine byproducts, and micropollutants.
