Who this pack is for

Refresh the water you use every day.

Loaded filters can let familiar tastes and smells return or restrict flow. Plan around 6–12 months, with earlier checks when water quality or use calls for them.

Better taste

Fresh carbon helps reduce chlorine taste and unwanted odours in water for drinking, cooking and coffee.

For everyday water at the kitchen tap.

Fresher showers

Less chlorine odour makes household water more pleasant to use, including in the shower.

For the smell you notice around the home.

Less grit

The polyspun and pleated cartridges capture particles such as sand, dirt and rust before they reach your taps.

For a compact system ready for fresh cartridges.

What's in the pack

A compact set for sediment and taste.

Measure these two.

Measure the cartridge you're replacing, not its housing.

A filter cartridge with two measurements marked: A, overall length end to end including caps or connectors; B, widest outside diameter.
A Overall length — end to end, including caps or connectors
B Outer diameter — at the widest point of the body

Will it fit?

Match your 10″ × 4.5″ cartridges.

Measure the cartridges already fitted, then compare their ends and seals. Housing dimensions alone do not confirm cartridge compatibility.

Measured it and still not sure?

Send a photo of the cartridge beside a tape measure and we'll tell you which size it is.

Nominal sizes vary a little between makers, so match the measurement rather than the label. What we can't tell you is how ours compares to a cartridge we didn't make and haven't tested, or whether a replacement affects your housing's own warranty; that one is between you and its manufacturer.

Only buyers we can match to an order can leave one, so the count is lower than it would be otherwise.

FAQ

A few practical answers before you order or change your filters.

Need help choosing? Call 0474 189 347.

How do I know it will fit?

This pack uses the 10″ × 4.5″ nominal format. Check the actual cartridge height, widest diameter, end caps and seals against your existing set before ordering.

When should I replace the filters?

Plan around 6–12 months, depending on water quality and use. Check sooner if taste, odour or flow changes. Follow the rating and replacement instructions for your filters.

Do all the filters need changing together?

This pack lets you refresh the supplied set together. Individual stages can load at different rates; follow your system guide when a single cartridge needs earlier attention.

Does this set reduce hardness or scale?

The confirmed supplied set contains polyspun sediment, CTO carbon and pleated sediment cartridges. It does not contain ion-exchange resin. Ask HFS about a suitable scale-treatment option for your system.

Can I change them myself?

Follow your system’s isolation, pressure-release, fitting and flushing instructions. If you cannot isolate it safely or are unsure, arrange help from HFS or a qualified plumber.

What if I order the wrong format?

Contact HFS before fitting or using the pack. Match dimensions, connectors and filtration purpose, and check your housing manufacturer’s warranty terms before using another brand.
