Indoor air quality has never been more important, and air purifiers have become essential for allergy sufferers, pet owners, and anyone concerned about respiratory health. Here’s what you need to know.
How HEPA Filtration Works
True HEPA filters capture 99.97% of particles 0.3 microns or larger, including dust, pollen, pet dander, mold spores, and many bacteria. Look for “True HEPA” certification to ensure effectiveness.
