The Puretec EM2-150 is a high-flow dual-stage whole-house water filtration system designed primarily for rainwater applications. It uses two 20-inch sediment cartridges to reduce dirt, rust, algae, sludge and fine particulate matter before the water travels through the home's plumbing system.
The current EM2-150-LF combines a washable PL20MP2 20 micron pleated sediment cartridge with a finer PX01MP2 1 micron polyspun sediment cartridge. With a published maximum flow rate of 150 litres per minute and 1½-inch BSP connections, it is designed for medium-to-large properties requiring high-flow point-of-entry filtration.
Installed Today offers the Puretec EM2-150 as a supply-only whole-house filtration system, with supplied-and-installed options available across eligible Brisbane and Gold Coast service areas.
The EM2-150 filters water at the point of entry before it is distributed throughout the home or building. Its two sediment-filtration stages progressively remove larger and finer suspended particles from the water supply.
This helps reduce sediment and sludge entering downstream plumbing, taps and appliances while maintaining the high flow rates required for whole-house applications.
The EM2-150 is a sediment filtration system. Puretec's current specification for this particular model does not list a carbon taste-and-odour cartridge, so chlorine or chemical reduction should not be assumed from the EM2-150 alone.
Puretec's EM2 specification places the EM2-150 in the medium-to-large residence category where higher whole-house flow is required.
The EM2 range is designed specifically for rainwater and provides high-flow sediment filtration before water enters the property.
With a maximum published flow of 150 L/min and 40mm connections, the EM2-150 suits installations requiring greater flow capacity than smaller whole-house filter systems.
The first-stage washable pleated cartridge captures larger suspended particles including dirt, rust and other sediment.
The second-stage 1 micron polyspun cartridge provides finer sediment filtration after the water has passed through the first-stage cartridge.
Point-of-entry filtration helps reduce sediment and sludge before the water reaches downstream plumbing, tapware and connected appliances.
*Puretec's current whole-house guide specifies 1 year parts and labour plus a further 9 years parts only. Consumable cartridges are excluded.
You need high-flow whole-house sediment filtration for rainwater and want to reduce dirt, rust, algae, sludge and fine suspended particles before water enters the property.
You specifically need chlorine reduction, taste and odour treatment, water softening, reverse osmosis or microbiological disinfection as part of the same system.
Confirm required flow, water source, available pressure, pipe size, installation location and whether additional treatment such as UV disinfection is required.
Puretec designs the EM2 Series specifically for rainwater. The manufacturer also lists the EM2-150 as suitable for use with mains water, rivers, dams and bore water.
The filtration requirement for untreated water depends on its actual microbiological and chemical quality. Puretec warns that the system must not be used with microbiologically unsafe water or water of unknown quality without adequate disinfection before or after the filtration system.
For rainwater intended for household use, the EM2-150 can also be used as sediment pre-filtration ahead of a suitable Puretec UV treatment system.
The EM2-150 uses two large-format 20-inch sediment cartridges in sequence so progressively finer particles are removed from the water.
The PL20MP2 washable pleated sediment cartridge provides coarse filtration and reduces larger particles including dirt, rust and algae.
The PX01MP2 polyspun sediment cartridge provides finer filtration down to a nominal 1 micron.
After passing through both stages, filtered water continues into the property's plumbing network and connected outlets.
The current Puretec EM2-150 uses two sediment cartridges rather than a dedicated carbon cartridge.
Stage 1 is a PL20MP2 20 micron pleated sediment cartridge and Stage 2 is a PX01MP2 1 micron polyspun sediment cartridge. Puretec's current product information describes this combination as 20 and 1 micron sediment filtration.
If chlorine, chemical taste or odour reduction is required, a model with appropriate carbon treatment or an additional treatment stage should be selected based on the water source and required outcome.
Designed for high-flow whole-house applications where larger pipework and higher simultaneous water demand are present.
A 20 micron first stage and 1 micron second stage provide progressive particle reduction with minimal unnecessary restriction.
The PL20MP2 pleated first-stage sediment cartridge is washable, helping extend useful service life where conditions permit.
Puretec specifies heavy-duty filter housings for reliable whole-house filtration applications.
The current EM2 design uses an integrated rust-proof, anti-flex aluminium wall-mount bracket.
The filter itself uses water pressure to operate and contains no powered filtration components or moving parts.

A 20-inch, nominal 1 micron polyspun sediment cartridge used for finer second-stage particle removal.
Puretec specifies genuine replacement cartridges to maintain system performance, applicable standards and manufacturer warranty conditions.
Puretec's current WH / EM maintenance guide specifies cartridge replacement every 6–12 months, with the manufacturer noting that cartridge life depends on water quality and usage.
Water with higher sediment loads may require more frequent cleaning or replacement. Reduced flow, visible cartridge loading or changes in water quality can also indicate that servicing is required.
Puretec recommends replacing housing O-rings approximately every 3–5 years to help maintain a watertight seal.
Yes. Puretec specifically lists the EM2-150 as suitable for UV system pre-filtration.
Sediment filtration before ultraviolet treatment helps reduce suspended particles that can interfere with effective UV exposure. The correct UV system still needs to be sized for the required flow and water quality.
The EM2-150 itself does not provide ultraviolet disinfection and should not be described as a standalone microbiological treatment system.
The EM2-150 is a point-of-entry whole-house filter and needs to be installed in a suitable position where the housings can be securely supported and accessed for cartridge servicing.
Puretec's current installation guide states that the system must be installed in accordance with local plumbing regulations by a licensed plumber.
Puretec lists the EM2 Series as being able to operate on gravity-feed pressure and the filtration system itself requires no electrical power.
Actual available flow from a gravity-fed system depends on tank height, available static pressure, pipe diameter, pipe length, fittings and downstream demand. The published 150 L/min figure is a maximum filter flow rating and should not be interpreted as a guaranteed gravity-fed flow rate.

The system is particularly relevant to rainwater-supplied properties requiring high-flow sediment filtration before household distribution or before a separate ultraviolet treatment system.
Existing pipe diameter, available water pressure, pump performance, mounting location and service access should be checked before installation.
Eligible Gold Coast customers can also order the EM2-150 with a matching installation option. The system should be located where the heavy-duty housings can be securely supported and where sufficient space remains below the filter bowls for future servicing.
Rainwater pump performance and existing pipework should be considered when selecting a high-flow whole-house filter so the complete system can meet the property's required water demand.
Puretec recommends changing the filter cartridges every 6–12 months depending on water quality and usage. The PL20MP2 first-stage cartridge is washable, which can help manage sediment loading between replacement intervals.
During cartridge servicing, the housings should be cleaned and the O-rings checked for damage and correct lubrication. Puretec recommends O-ring replacement approximately every 3–5 years.
After cartridge replacement, the current manufacturer guide instructs the installer to purge trapped air, flush the system and check the housings and connections for leaks.
The EM2-150 provides dual-stage sediment filtration to reduce particles including dirt, rust, algae, sludge and finer suspended matter.
The system has two filtration stages.
Stage 1 uses the Puretec PL20MP2, a 20-inch washable pleated sediment cartridge rated at 20 micron.
Stage 2 uses the Puretec PX01MP2, a 20-inch polyspun sediment cartridge rated at a nominal 1 micron.
No dedicated carbon cartridge is specified for the current EM2-150. Its published cartridge combination is PL20MP2 plus PX01MP2, providing 20 and 1 micron sediment filtration.
Puretec does not list chlorine reduction as a treatment function of the current EM2-150 cartridge combination. A system with appropriate carbon treatment should be considered where chlorine reduction is required.
