What are Self-Cleaning Filters?
Self-cleaning filters are advanced filtration systems that use nanotechnology to remove contaminants from water, air, or other liquids without the need for frequent manual cleaning. The integration of nanomaterials enhances the efficiency and durability of these filters, making them ideal for a wide range of applications.
How Do They Work?
The core mechanism of self-cleaning filters often involves the use of
nanoparticles or
nanostructured surfaces that possess unique properties like hydrophobicity, photocatalytic activity, and antimicrobial effects. When contaminants come into contact with these surfaces, they are either repelled, broken down, or neutralized, ensuring that the filter remains clean and effective over extended periods.
