About us

Absorb It Ltd supplies a broad customer base with quality sand filtration media.

Absorb It purchased Works Filter Ltd and Silicon Industries Ltd in April 2022, after the previous owner retired. Prior to Absorb It taking the reins, Works Filter Ltd, in association with Silicon Industries Ltd, supplied the wider North Island Region with high-quality, silicon-based filter sand, and other media, to treat iron and manganese for over 46 years. 

Absorb continues to proudly supply a broad customer base with quality sand filtration media.
