2-in-1 Composite Structure:Folded Composite Melt-Blown Media＋Honeycomb Activated Carbon Layer
The front layer uses high-density folded composite melt-blown material-with 3-5 times more surface area than flat media-effectively trapping tiny particles.The back layer is filled with high-quality granular activated carbon (100-200 mesh) in a honeycomb structure,adsorbs formaldehyde, benzene, TVOC, odors.Air passes through the Composite melt-blown → honeycomb carbon adsorption, achieving simultaneous removal of particulate and gaseous pollutants.

FAQ
Q: Is the paper frame durable enough?
A: Yes, we use thickened water-resistant paper frame that maintains shape during normal use. Just avoid extremely humid environments.
Q: What is the weight of the honeycomb activated carbon layer?
A: Activated carbon filling ranges from 200g to 500g depending on specifications. Please refer to the product specification sheet, and we can adjust the carbon filling according to customer requirements.
Q:Do you support custom sizes?
A: Yes, we offer OEM customization. Just provide drawings or samples for production.
Q: Can this filter remove formaldehyde?
A: Yes, the honeycomb activated carbon layer effectively adsorbs formaldehyde, toluene and other harmful gases. Please note activated carbon has saturation limits, so regular replacement is recommended for optimal performance.
