Crystal Water Filter – For Cars and Windows – 6 Litre


Crystal-Clean-Wash-FilterMains water contains impurities and salts which leave spots and smears on the paint after washing. Some of this will be due to scale caused by Calcium and Manganese. A water softener will remove Calcium and Magnesium and therefore preventing scale formation.  However, some impurities remain and if you want a spot and smear-free finish on your paintwork then our specifically designed car wash filter is the best for this.

Our filter has been specifically designed to provide ultra-pure water for the washing of cars and windows. Inside the housing is a special media that removes all impurities from water. This means that when water evaporates on paintwork or glass, no spots or streaks are left behind, leaving you with a perfect finish.

The filter can be connected to your hosepipe. As the media has a finite life, we suggest using it for a final rinse, though you can use it for the whole car washing process. The media will produce up to 700L of water before it needs replacing (depending on local water hardness) and a final rinse usually uses around 10 litres of water.

The media we use is Purolite MB400. Purolite is a market leader in filter media technology and this is the highest quality product available for this application.

Comes complete with 6L of media.

Replacement 6L bags of media are also available.

Changing the media is a simple process. Please see ‘Downloads‘ tab for instructions.

Connections: 3/4″ male thread x male click

Please note – The filter media can cause eye irritation. Please read the Purolite safety data sheet prior to use.

    So I purchased a new Vw Golf R 7.5 Lapiz Blue and the water marks kept on appearing soon ascthe water dried off, this left me absolutely frustrated and annoyed ascmy hour or more effort kept going down the drain. I then started too do a tad little bit of research and then I found this site that offering a solution too my problem. I called up and spoken too a member off staff who was very helpful and told me ins and out off the product and then I ordered too see if it was the real deal, wwll by this review I’ll say you can guess that it actually is. My car is spot free and I didnt even need the window polish or glass cleaner too shine them as the water did the job on its own, absolutely love it and belive me when I say GET THE PRODUCT AND TRY FOR YOURSELF you will not be disappointed at all.
