The endotoxin removal products sold by DEOVOS differ from those of other brands.




Previously, we mentioned that most commercially available products work through electrostatic adsorption, combining positively charged materials with the negatively charged areas of LPS to remove endotoxins.

DEOVOS team also sells products that remove endotoxins using electrostatic adsorption.
So, what's the difference?

They all use the same electrostatic adsorption principle,
so why are there so many different products with varying price ranges?
What are the differences between these endotoxin removal filter products?

In terms of filter cartridge manufacturing methods, the production process is actually quite similar.
For filter products with special functions, the most significant factor is the middle main filter media.
The stability and material properties of the main filter media directly affect its effectiveness in removing endotoxins.
We have compiled the following possible influencing factors for you, including...

• Filter media material
• Modified stability
• Salt and pH sensitivity
• Protein adsorption
• Removal rate
• Sterilization resistance

The DEOVOS team chose modified nylon as the membrane material to create a product capable of removing endotoxins.

Due to the inherent properties of nylon, it naturally contains amine (–NH) and amide (–CONH) functional groups.

Therefore, it is easier to achieve a positively charged property through modification, and compared to other materials, modified nylon exhibits higher stability.

However, the membrane material's effectiveness in protein adsorption is also a crucial factor.

Protein adsorption strength: Nylon 66 > Polyamide > PVDF.
The appropriate membrane material should be selected based on experimental results and the required protein retention strength.


DEOVOS often says, "There's no such thing as the 'best' filter; there's only the 'most suitable' filter."  
Our team can provide the most appropriate solution based on your specific product requirements or budget.

So, how do you choose the right air filter for your factory?
