Frequently Asked Questions
A True HEPA (High-Efficiency Particulate Air) filter is certified to capture 99.97% of airborne particles down to 0.3 microns in size. This includes microscopic allergens like pollen, dust mites, mold spores, pet dander, and fine smoke particles that standard filters miss.
Always check the manufacturer's recommended room size or Clean Air Delivery Rate (CADR). For optimal performance, look for a unit designed to handle a room slightly larger than your actual space, ensuring the air is completely filtered multiple times every hour.
Standard HEPA filters trap physical particles, but they do not absorb chemical vapors, smoke odors, or volatile organic compounds (VOCs). To neutralize odors and gases, look for an air purifier that also includes an activated carbon filter stage.
