Coway markets its Green True HEPA at '99.999%' efficiency — a higher headline number than SCA's 99.97% at 0.3μm. The 99.97%/0.3μm spec is the EN 1822 H13 medical-grade standard that healthcare environments actually require for documentation purposes. Headline percentages above this are typically measured against different particle sizes and aren't directly comparable to clinical procurement specs.
Coway air purifiers rely entirely on capture-stage filtration with no active germicidal treatment. For dental, medical, and procedure environments where pathogens captured in the filter media can remain viable for hours, SCA's enclosed UV-C+ chamber actively destroys what's been captured — a meaningful clinical advantage.
Coway products are engineered for residential duty cycles — daily use during waking hours. Clinical and commercial environments require 24/7 operation without performance degradation. SCA components are rated for continuous workload; consumer units typically aren't, and operating one outside its design envelope shortens its life and voids the warranty.
Healthcare procurement often requires AHU-level documentation: filter test certificates, HEPA H13 traceability, UV-C dose validation. Coway provides consumer-level documentation (AHAM verification). For Joint Commission audits, OSHA documentation, or infection-control compliance, the documentation gap is consequential.
Coway carries standard consumer certifications (AHAM Verifide, Energy Star, CARB). SCA products have been independently evaluated by Clinicians Report — the dental profession's most trusted product-evaluation organization since 1976.
Coway makes solid consumer air purifiers with strong retail availability, attractive design, and Energy Star efficiency. For home use, the Airmega and Mighty series are well-regarded choices in the residential market.
For healthcare facilities, dental practices, and commercial environments, the requirements are categorically different: active pathogen destruction, medical-grade filtration with traceable certificates, commercial-rated duty cycle, and clinical validation from a professional body.
Coway and SCA serve different markets. The question is which market your environment belongs to — and whether 'verified for residential' is the standard your facility actually has to meet.
