Aquano Klarify M-320 Triple-Stage Whole House Water Filtration System

Enjoy cleaner, fresher-tasting water throughout your home with the Aquano Klarify M-320.

Designed for medium to large New Zealand homes connected to a mains water supply, this three-stage whole-house filtration system reduces sediment, chlorine, unwanted chemicals, unpleasant tastes and odours before the water reaches your taps, showers and appliances. Its 20-inch Jumbo housings and maximum system flow rate of 120 litres per minute provide the capacity needed for larger households without limiting filtration to a single drinking-water tap.

The M-320 arrives pre-assembled and includes three replaceable filter cartridges, pressure gauges, housing spanners and neoprene weather-protection covers. Durable metal construction and reversible installation capability help make it practical to install, monitor and service.

Why Choose the Aquano Klarify M-320?

Filter Water Throughout the Whole Home

Installed at the point where the mains supply enters the property, the M-320 treats water before it is distributed around the house. This means the benefits extend beyond drinking water to showers, bathroom taps, kitchen taps and water-using appliances.

Three Dedicated Filtration Stages

Rather than asking one cartridge to handle every water-quality issue, the M-320 uses three separate cartridges to progressively reduce sediment, chlorine, chemicals, taste and odour.

Designed for Medium to Large Homes

The system uses three 20-inch Jumbo housings and has a stated maximum flow rate of 120 L/min, giving it the capacity required for homes where several outlets may be used at once.

Easier Performance Monitoring

The three pressure gauges provide a visible way to monitor pressure through the system. A growing pressure difference can help indicate that cartridges are becoming restricted and may need attention.

Suitable for Indoor or Outdoor Installation

The M-320 may be installed indoors or outdoors. For outdoor installations, the supplied neoprene covers must be fitted to protect the housings from frost, direct sunlight and water exposure.

Supplied Ready for Installation

The complete unit arrives pre-assembled and includes the cartridges, housing spanners and weather-protection covers required for installation and routine servicing.

How It Works

Water passes through three filtration stages before entering the home’s plumbing system.

Stage 1: Fine Sediment Filtration

The first polyspun sediment cartridge captures dirt, rust, silt, sand and other suspended particles. Aquano specifies filtration down to 1 micron for the M-320 system. Removing this material first also helps protect the carbon stages that follow.

Stage 2: Carbon-Impregnated Filtration

The second cartridge combines further particle filtration with carbon treatment. Its role is to help reduce sediment, chlorine and chemicals before the water reaches the final polishing stage.

Stage 3: Granular Activated Carbon Filtration

The final granular activated carbon cartridge is designed to reduce chlorine and improve unwanted taste and odour. It acts as the final polishing stage before filtered water is distributed throughout the home.

Best Suited For

The Aquano Klarify M-320 is best suited to:

• Medium to large homes
• Properties connected to a mains or municipal water supply
• Households concerned about sediment, chlorine, taste or odour
• Homes wanting filtration from more than one tap
• Indoor or appropriately protected outdoor installations
• Households requiring a high-capacity, serviceable filtration system

This system is intended for mains water filtration. It must not be used with microbiologically unsafe water, or water of unknown quality, unless appropriate disinfection is installed.

Key Specifications

Installation

Installation must be completed by a licensed plumber and comply with applicable New Zealand plumbing requirements. The unit is installed on the cold-water supply at the point of entry so water is filtered before being distributed around the home.

Installation requirements include:

• Mounting the unit securely to a solid surface
• Providing adequate access beneath the housings for cartridge removal
• Installing an upstream isolation valve for servicing
• Supporting connected pipework so its weight does not stress the system
• Protecting the unit from water hammer
• Using unions to simplify future servicing
• Installing an approved pressure-limiting valve where line pressure exceeds 500 kPa
• Installing an approved dual-check backflow-prevention device for point-of-entry installations
• Protecting the system from freezing
• Using the supplied neoprene covers when installed outdoors

Allow sufficient room around and beneath the system so each housing can be removed without dismantling surrounding plumbing.

Maintenance

Aquano recommends replacing the filter cartridges every 6–12 months. Actual cartridge life will depend on incoming water quality, household usage and the amount of sediment being collected.

During servicing:

1. Shut off the incoming water supply.
2. Open a downstream tap.
3. Use the pressure-release buttons to depressurise the system.
4. Remove each housing using the supplied spanner if required.
5. Remove the used cartridges.
6. Clean the housings.
7. Inspect the O-rings and replace any that are damaged.
8. Lubricate suitable O-rings with food-grade silicone.
9. Fit the new cartridges centrally and in the correct order.
10. Refit the housings without overtightening.
11. Restore the water supply slowly.
12. Flush the system for 2–10 minutes.
13. Check all joints and housings for leaks.

The pressure gauges should also be checked periodically. A noticeable pressure drop through the system may indicate that one or more cartridges are becoming restricted.

Frequently Asked Questions

Does the M-320 filter water throughout the entire house?

Yes. It is a point-of-entry system installed on the incoming mains supply, allowing filtered water to be delivered to outlets throughout the home.

Is the M-320 suitable for a large household?

Aquano describes it as suitable for medium to large homes. It uses 20-inch Jumbo housings and has a stated maximum system flow rate of 120 L/min.

Does it reduce chlorine?

Yes. Its carbon filtration stages are designed to reduce chlorine and improve unwanted taste and odour.

What sediment does it remove?

The polyspun sediment stage is designed to capture material such as dirt, rust, silt and sand.

What is the finest filtration rating?

The manufacturer states that the M-320 removes particles down to 1 micron.

Does the system remove bacteria and viruses?

The M-320 is a cartridge filtration system and is not presented by Aquano as a microbiological disinfection system. Do not use it with microbiologically unsafe water or water of unknown quality without suitable disinfection.

Can it be installed outside?

Yes, provided the supplied neoprene covers are used to protect the housings from frost, direct sunlight and water. The system must also be protected from freezing.

How often should the cartridges be replaced?

Does it require a plumber?

Yes. Aquano states that installation must be completed by a licensed plumber and comply with local plumbing regulations.

What happens if the household water pressure exceeds 500 kPa?

An approved pressure-limiting valve is required where line pressure exceeds 500 kPa.

Are the cartridges replaceable?

Yes. All three cartridges are replaceable, and the supplied housing spanners assist with routine servicing.
