Product Q&A

Q:Can air purifiers remove formaldehyde?

Partially, with limitations: Carbon filters temporarily trap formaldehyde (require frequent replacement) Advanced models with catalytic decomposition (e.g., photocatalysis) break it down permanently Note: Ventilation remains the most effective solution

Q:How to choose HEPA filter grades?

H11-H12: Adequate for most homes (95-99.5% efficiency) H13-H14: Medical-grade (>99.97%, ideal for allergy sufferers) Avoid E10 or below - insufficient for health protection

Q:Should air purifiers run 24/7?

Context-dependent: High pollution: Continuous operation recommended Maintenance mode: Smart sensors can auto-adjust fan speed Energy tip: Use lower speeds when unoccupied

Q:Why does my purifier emit odors?

Common causes: New filters: Initial carbon 'break-in' smell (resolves in 48hrs) Dirty filters: Microbial growth on saturated filters Ozone risk: Avoid electrostatic precipitators (potential ozone byproduct)

Q:How often to replace filters?

HEPA: 6-12 months (depends on PM2.5 levels) Carbon: 3-6 months (loses adsorption capacity) Smart indicators: Modern units alert when replacement needed
