xOverview
The FMDZFL 2-pack 400 Replacement Filter is crafted for the Puroair 400 air purifier, offering a practical, multi-layer filtration upgrade. While not an OEM product, this compatible pair is designed to fit the unit securely, making routine maintenance simple for busy homes and small offices alike.
Three-in-One filtration for everyday air
At the core of this filter are three stages working together: a fine pre-filter that captures larger particles like pet hair and dust, an H14 True HEPA layer that traps microscopic particles as small as 0.1 microns, and an activated carbon layer that helps address odors from cooking, smoke, and daily air activity. The combination aims to support a cleaner feel in living spaces where air quality matters.

Real-world use cases
In homes with pets or frequent cooking, the 3-in-1 setup can help manage pet hair, pollen, and lingering odors.
