Waveair Holding Tank Vent Filter

Keeping our oceans and waterways clean. Waveair filters out the foul smells expelled from waste water and sewage holding tank vents. Many boaters will recognise the distinctive “below decks” odour encountered onboard.
  • Targets hydrogen sulphide. Specifically designed to remove H2S, the main cause of the smell.
  • New filter media. Large pore volume and a high surface area maximise the capacity of the filter.
  • Safer on board. Gas heavier than air can accumulate in low-lying areas, so cleaner vent air matters for safety.
  • Easier on the stomach. For some people, unpleasant odour combined with a boat's motion can make sea sickness worse.
  • Two sizes, three hose sizes. Waveair at 430 mm and Waveair Micro, each with 16, 19 or 25 mm hose connections.

About this product

How it works

Waveair is fitted in the vent line of a waste water or sewage holding tank, as shown in the schematic. Air expelled from the tank vent passes through the filter, and its specialised media removes the foul smell. The media has a large pore volume and a high surface area to maximise the capacity of the filter.

What it removes

  • Foul smells from waste water and sewage holding tank vents
  • Hydrogen sulphide (H2S)

Why it matters

The distinctive “below decks” odour is more than unpleasant. Gas heavier than air can accumulate in low-lying areas, which makes filtering the vent crucial for safety on board. For some people, a combination of unpleasant odour and a boat’s motion can also make sea sickness worse. NOAA’s National Ocean Service says that strong odours can magnify a person’s symptoms of motion sickness.

Where to install it

In the vent line from the holding tank, between the tank and the vent outlet. Use the brackets supplied to fix the filter in place.

Suitable boat sizes

Waveair is available in two sizes to suit a wide range of tanks: Waveair at 430 mm long and Waveair Micro at 200 mm long. Both are available with 16, 19 or 25 mm hose connections.

Installation

Each filter is supplied complete with brackets and hose tails. Choose the hose tail size that matches your vent hose: 16, 19 or 25 mm.

Replacement filters
