The PuroAir HEPA Replacement Air Filter is a high-efficiency, 3-layer filter designed to fit PuroAir HEPA air purifiers. It's composed of a pre-filter screen layer to capture large particles, a HEPA filter layer to eliminate up to 99.9% of microscopic allergens⁴ and pollutants, and an activated carbon filter layer to absorb odors¹, smoke⁴, and harmful VOCs⁵. This best-in-class filtration system effectively reduces airborne particles like dust³, pollen⁴, pet dander⁴, and other allergens⁴, ensuring the highest quality air and a healthier environment in your home or office at all times.

PuroAir Air Filter Replacements for Air Purifiers are designed to filter dust³, pollen⁴, smoke⁴, allergens⁴, carbon monoxide, VOCs⁵, mold⁴, and ultra-fine air particles.

We recommend replacing your air purifier filter every 3 months or 90 days. If not replaced within this timeframe, the effectiveness of your air purifier may decrease due to the build-up of air pollutants. However, during periods of poor air quality caused by increased allergens⁴, wildfire smoke⁴, home renovations, airborne illnesses, and other factors, it is recommended to replace the filter sooner.
