What is a key feature of HEPA purifiers?

HEPA purifiers are designed to be highly effective at capturing a wide range of airborne particles, particularly common allergens. The term HEPA stands for High-Efficiency Particulate Air, indicating that these filters can trap at least 99.97% of particles that are 0.3 microns in size. This includes pollen, pet dander, dust mites, and smoke particles, which are all major allergy triggers. The design and technology behind HEPA filters ensure that they can remove harmful allergens from the air, creating a cleaner and healthier indoor environment.

In contrast, capturing larger particles, while beneficial, is not the primary feature that defines the efficiency of HEPA filters. Additionally, saying they are not effective for allergens is inaccurate because their primary utility is indeed in removing allergens. Operating silently can vary depending on the specific model of the HEPA purifier; thus, it's not a defining characteristic. The main focus remains their unparalleled ability to filter out allergens effectively, thereby supporting better air quality.
