MitoSyne AirGuard True-HEPA Purifier

Particle filtration sized by clean-air delivery, room volume and noise rather than a square-footage headline.

AirGuard combines a sealed mechanical path, true HEPA-grade media and disclosed filter costs for bedrooms and workspaces.

A closer look

AirGuard focuses on the variables that determine how effectively a purifier serves a room: clean-air delivery rate, air-change rate, operating noise and filter upkeep. Smoke, dust and pollen ratings are stated separately, with recommended room sizes calculated at four and five air changes per hour. A sealed filtration path limits bypass, while a substantial activated-carbon stage adds capacity for selected odors. The unit operates without intentional ozone generation. Sleep mode balances airflow with quiet operation, and filter life, replacement price and availability are shown before purchase. Used alongside ventilation and source control, AirGuard offers a practical way to reduce airborne particles in a defined space.

The details that matter

• Verified smoke, dust and pollen CADR
• Sealed mechanical filtration path with true HEPA-grade media
• Substantial activated-carbon stage with disclosed media weight
• No intentional ozone generation; ionization absent or physically disabled
• Quiet sleep setting and transparent annual filter-cost estimate

Why it belongs

Environmental exposure is easier to act on when performance is expressed in measurable terms. AirGuard keeps room sizing, airflow and ongoing filter costs visible.

What the evidence supports

EPA notes that properly sized portable air cleaners can reduce particles and that health improvements in studies are generally small and context-dependent. Source control and ventilation remain essential.

What it is designed to do

Designed to reduce airborne particles in appropriately sized rooms through sealed mechanical filtration, with independently stated CADR.

Use and care

Keep air intakes unobstructed. Replace filters on schedule. An air purifier does not correct carbon monoxide, radon, gas leaks, mold sources or inadequate fresh-air ventilation.
