Frequently Asked Questions
What is a HEPA filter?
A HEPA (High-Efficiency Particulate Air) filter captures 99.97% of airborne particles down to 0.3 microns, including dust, pollen and pet dander. It’s the gold standard for allergy relief and air purification.
How often should I replace the filter?
Most manufacturers recommend replacing HEPA filters every 6 to 12 months, depending on usage and air quality. Carbon filters may need more frequent changes, typically every 3 to 6 months.
