Buying Guide for Medical Grade Air Purifiers
Filtration Technology
True HEPA filters are critical for medical grade purification, capturing at least 99.97% of particles 0.3 microns in size. Some models, like the Medify MA-40 and InvisiClean, use H13 or H14 HEPA filters that capture even smaller particles (down to 0.1 microns). Activated carbon filters are beneficial for absorbing odors, VOCs, and smoke.
Coverage Area
Choose an air purifier that matches your room size or larger. For open-plan houses or large living rooms, devices like BLUEAIR Blue Pure 211i Max cover over 3000 sq ft, while smaller rooms require less powerful models. Ensure airflow (CADR) matches your space for efficient air exchange.
Noise Level
Noise tolerance varies by user, but quieter purifiers (below 50 dB) are better suited for bedrooms or offices. Some models offer low-speed sleep modes with minimal sound disturbance, such as the Medify MA-40 and LEVOIT Core 300.
Additional Features
UV light sterilization (InvisiClean Claro) can help inactivating bacteria and viruses. Smart features like auto modes, air quality sensors, app/Alexa control enhance usability. Energy Star certified models minimize electricity consumption.
Certifications and Testing
Bearing certifications from CARB, Energy Star, UL, or independent lab testing indicates reliable performance and safety. Look for products with tested virus and bacteria efficacy when considering medical-grade purifiers.
Maintenance and Filter Replacement
Regular filter changes are necessary to maintain efficacy. Check availability, cost, and ease of replacement filters. Some brands provide indicators reminding you when it’s time to replace filters.
