Product Description

Caravan and Boat Filter Replacement Cartridge

This caravan / boat filter option gives you sweet tasting, purified water. It removes the taste of chlorine and other unpleasant odours giving you fresh drinking water on tap 24/7

This is a perfect compatible replacement for common caravan and boat filters like the Whale Aquasource WF1230 / WF1230B and others. (If you have the 12mm Whale Aquasource WF1230 click here

For this filter you should already have a tap and connection to your water supply - you only want a new cartridge.

I use the filter system on my boat, which is also my home. Since fitting the system I have not bought any bottled water. I am very pleased with it and recommend your company often." Independent Review by David H

Please note: Cost of replacement cartridge for returning customers is only £15.95. So next season you will save even more money!

The filter needs to be changed every 6 months - so it will give you a full season's service.

(Please note once "wet" the filter needs to be replaced after 6 months regardless of the amount of water used. This is because chlorine has been removed from the water inside the filter - which can lead to bacterial growth...)

Wait ! Please tell us your required Pipework / Tube size

Our filters accept 1/4 inch tube/piping as standard. However, we can supply adapters to fit 12mm outside diameter(the most common caravan size).

These normally cost around £12 (see our accessories page). But to get you going we will give these at less than half price- if you buy a cartridge from us.

Price without adapters is £15.95. With adapters is £19.95

Please note you only need to buy the adapters once - for ongoing use. (For example, your replacement cartridge cost next season will only be £15.95)

(If you need a different size than 12 mm simply call us first)
