Davey Microlene 10" Standard Twin Filter Housing - WaterMark Certified, Dual Stage, 20mm Ports NZ

The Davey Microlene AS10A is a dual-stage 10" standard filter housing that runs two cartridges in sequence — letting you tackle sediment and taste or odour in a single compact unit. Built from reinforced polypropylene with built-in pressure relief valves on both bowls, it suits underbench, outdoor tank, and inline installations.

Certified to WaterMark WMTS-103 (Lic. 032114) and tested in compliance with AS/NZS 4020 for use in contact with drinking water. Manufactured under ISO 9001 quality management and ISO 14001 environmental management systems.

Available as a housing only, or as a pre-loaded kit matched to your water source — select from the dropdown. The housing only variant ships with both bowls empty, ready for you to choose your own cartridge combination.

Includes mounting bracket, fixings, and housing spanner.

Bore water quality varies significantly. We recommend testing your bore water before selecting a filtration system — get in touch and we'll help you choose the right configuration for your supply.

Pairing with UV treatment

Both kits are designed to work upstream of a Microlene UV24 system. The pre-filtration stages remove the sediment and particles that reduce UV effectiveness. Max UV flow is 35 lpm when paired with KAS10A, or 15 lpm when paired with KAS10AM.
