The air filter replacement uses activated carbon as main filter media with good surface adsorption ability to effectively remove odors and harmful gases in the air. Different activated carbon materials can be selected according to the needs of the environment such as activated carbon particles, activated carbon non-woven fabric, etc.

The air filter is widely used in residential air filtration for odor remove and air-conditioning ventilation. It can remove air odors, paint spray workshop odors, museums moldy smells, and other odors.

Main filters media: Coconut shell activated carbon particles, coal activated carbon particles, activated carbon fiber cotton, activated carbon foaming cotton, activated carbon non-woven fabric.

Inside and outside frame: PP honeycomb structure, cardboard frame, aluminum profiles.

• Coconut shell activated carbon has a highly developed microporous structure, by deep activation and aperture adjustment process, the specific surface area is further increased so the adsorption capacity and the adsorption speed is enhanced, deodorant efficiency can be larger than 95%.
• The filter mesh is made of 12mm diameter honeycomb PP material and the filling rate is 50%-100% optional.
• It is recommended to add a medium-efficiency filter to the front of the activated carbon filter to protect the activated carbon filter and extend its service life.
• We can assemble different kinds of activated carbon such as coal activated carbon, coconut shell activated carbon and so on according to your needs. Youjie can also customize the formula to further treat activated carbon to improve its performance in removing certain king of harmful gases such as formaldehyde, ammonia, benzene, etc.

The following filter specifications can be adapted to common purifiers. Youjie can also customize special size filters according to your requirements.

In addition to the most common 25mm thickness frame, the conventional thickness can be 10/21/25/34/46/50mm; the thickness of the cardboard frame can be customized within the 9-40mm range according to customer’s requirements.
