Activated carbon honeycomb filters are specially designed for Central air conditioning and Centralized ventilation systems. This equipment is aimed at removing odours and harmful gases from the air. The filter usually uses the through-hole structure of the plastic honeycomb core as the frame, filled with nutshell carbon, coconut shell carbon, or other fillers that can absorb harmful gases in the air. It has very excellent gas aerodynamic properties, Small volume while large surface, High adsorption efficiency with low wind resistance, Longer life span, and no need for frequent replacement, which is very popular with customers in the market.

Differences in the core material
Currently, there are three main types of honeycomb-activated carbon filters used in the filtration industry: paper honeycomb, aluminium honeycomb and pp honeycomb.
l Paper honeycomb core
The price of paper honeycombs is the lowest among them. The material itself is soft and can be made into verified shapes, and it is an insulated material.
But paper honeycomb is flammable, has poor mechanical properties, Cumbersome processing, and needs to add glue. Have Poor tear resistance, fold resistance, puncture resistance, etc.
l Aluminum honeycomb core
Aluminium honeycomb cores have good mechanical properties, high strength and stiffness. Have the thinnest cell thickness, fireproof and flame-resist, Insect-proof and moth-proof.
However, it is conductive and prone to corrosion and corrosion. The material cost is the highest and the processing is cumbersome. It needs to be glued. It is easy to produce metal abnormal noise after degumming. And the edges are sharp and prone to injury.
l Plastic (polypropylene or polycarbonate) honeycomb core
Polypropylene honeycomb has good mechanical properties, is easy to process， is environmentally friendly, and is a poor conductor of electricity and heat. It can be simply cut into various shapes with a utility knife. And it has good adhesion and weather resistance performances. The price is medium but the service life is long.
PP honeycomb panel is made of polypropylene. It is a lightweight (hollow structure), non-toxic, waterproof, shockproof, long-lasting and corrosion-resistant material. Compared with cardboard, it has the advantages of being waterproof, colourfast and corrosion-resistant. Compared with aluminium honeycomb, it is low cost, waterproof and anti-oxidation, safe to operate and non-conductive.
At present, PP/PC honeycomb is the best core material of honeycomb activated carbon filter. Due to its outstanding performance, there is an increasing tendency for it to replace other honeycomb cells.
Qingdao Achieving honeycomb panels have below features：
1. High surface flatness
Using the CNC cutting equipment, our tolerance can be controlled within ±0.03mm.
2. Mechanical properties
we use new environmentally friendly polypropylene raw materials and process control to ensure that the wall thickness of the honeycomb is uniform and smooth, and the hole diameter is round.
3. Eco-friendly and non-toxicity
PP material is not only harmless to the human body and nature, does not contain toxic substances, and can also be recycled and reused. Realize the value of secondary use. In line with modern environmental protection concepts.
4. Customizable service
Whether for the cell size, density, size or thickness, it can be adjusted according to customer requirements.
