This canister filter suits keepers running medium-sized freshwater aquariums who need high flow and a large media capacity. The Health Water 4 model is the larger unit in the new Health Water series, which replaces the earlier HW line with changes to the body, the lid seal, the motor and the air handling.
Why it matters
- Leak-proof lid: Internal guide rails hold the lid in the correct position, so it closes square to the canister and the main seal cannot be pushed out of alignment.
- Reinforced canister: Support columns in the media basket add rigidity and, according to the manufacturer, dampen vibration to reduce operating noise.
- Air handling: Flow channels and a relocated impeller let air bubbles pass out through the outlet, so the filter does not hold air pockets that block flow.
- Lower power draw: The new motor reduces energy consumption by 22% compared with the previous HW generation.

What it works with
The filter is matched to freshwater aquariums of about 300 to 500 l, where the 2000 l/h flow and the adjustable inlet and outlet lengths allow it to be placed behind the tank or in a cabinet. The UV-C lamp in the unit is intended for water treatment alongside mechanical and biological filtration in the canister.

Frequently asked questions
The filter is designed for aquariums up to 500 litres and is rated at 2000 l/h. The minimum recommended aquarium size is 300 litres.
Yes, this model includes a UV-C lamp. The filter's total power consumption is 45 W, but the data sheet does not specify the lamp's own wattage.
The lid has guide rails that hold it in the correct position when closed, which the manufacturer says prevents the leaking caused by a tilted lid. The sealing design is meant to stop the common leak problem seen in the previous HW series.
The pump housing and impeller were redesigned so that air bubbles pass out through the outlet, so there is no manual priming pump where air used to collect. The manufacturer states this avoids the long air-lock problems common in older bucket filters.
The intake tube can be extended from 15 to 60 cm using modules, and the outlet spray bar from 20 to 40 cm, with the outlet able to rotate. The set includes suction cups, hose clamps and edge brackets for mounting on the tank rim.
