How an order works
Send us the details
A part number, size and micron, a photo of the old filter, or a water analysis if you need a plant. WhatsApp is fine.
We check and quote
An engineer checks fit, material and sizing before we quote, so you do not end up with a cartridge that does not seal.
Dispatch or build
Stock consumables and spares ship directly from our warehouse. Plants are built to your water analysis and commissioned at your site, wherever it is.
Repeat orders
We keep your sizes on record, so the next order of cartridges or bags takes one message.
