The GermGuardian AC4825E is a True HEPA air purifier with activated carbon filtration designed for medium-to-large rooms. It covers up to 743 sq ft with a CADR of approximately 218 (dust/pollen/smoke combined), circulating air in smaller bedrooms every 12.5 minutes. The unit features three fan speeds including a quiet sleep mode, an optional UV-C light stage, and pre-filtration for larger particles.
Filtration & Performance: Captures 99.97% of particles ≥0.1 microns (dust, pollen, pet dander). Activated carbon reduces cooking and pet odors. No built-in air-quality sensor or smart controls—purely manual speed selection.
Build & Certification: CARB Certified (zero ozone), ETL Certified, independently tested in the USA. 3-year warranty. Weighs 8.55 lbs; footprint is compact at 6.75"W × 22"H.
Running Costs: Replacement GermGuardian HEPA Filter B (~$30–40 per set, typical 6–12 month cadence). No app or scheduling; no energy-star rating provided, but tower format suggests moderate power draw.
Ideal for: Allergy sufferers, pet owners, bedrooms, home offices, dorms. Best in small-to-medium rooms; advertised 743 sq ft is upper range and realistic only on high speed.
