Carbon Filters

Our carbon block filters are a trusted solution for window cleaners looking to remove impurities from their water with maximum efficiency. These window cleaning carbon filter blocks work well in both professional and domestic cleaning systems. 

Within our selection, we have Granular Activated Carbon (GAC) and KDF Media, which are premium solutions that work together to reduce chlorine, volatile organic compounds (VOCs), pesticides, and unpleasant odours, as well as inhibiting bacterial growth within the filter. 

A professional carbon block will help you achieve streak-free results on glass, which is why they’re so widely used across the industry. To find solutions for other industries, please click here.

Our Carbon Block Filters

Carbon block filters are particularly popular with commercial cleaning, mobile cleaners, and facilities managers who need consistent, purified water that won’t leave residue or staining. 

Our collection includes both standard 2.5 and jumbo-sized 4.5 filters, available in 10" and 20" lengths, making them compatible with most systems. 

Our solid carbon block cartridges are ideal for fine particulate removal (typically 0.5 to 5 microns), and Granular Activated Carbon (GAC) filters, which offer faster flow rates and are great for general-purpose chemical adsorption. 

For applications where bacterial control and heavy metal reduction are a priority, such as outdoor cleaning or rural water supplies, GAC/KDF media filters are likely your best choice. 

Catalytic carbon filters are perfect for breaking down persistent compounds like chloramines that traditional carbon can’t fully remove.

We only stock the very best brands in the industry, including our own great-value Finerfilters branded products, all available with fast delivery.
