The 'state of the art' cleaning process of filter cartridges removes 99.9% of collected media. The remaining amount leaving only a percentage to be considered "pre-coat" for your filters, which has been proven to be a more efficient than a "new" filter (Outside laboratory test submitted upon request).

Filters are cleaned with pressurized air, which is found to be better for a filter than wet washing, which can result in a cleaned filter being brittle and breaking.

After being cleaned, each filter is tested for air permeability with the results for each filter recorded and easily accessible to the customer via our customer service website.
