Larger 25 Litre resin capacity 0 PPM in-line water filter, ideal for professionals and serious detailers with collections of cars. The largest one, on the right.

Works in exactly the same way as the 7 litre version, should typically produce approx. 1400 litres of pure filtered water which will leave NO water spots on your vehicle, no matter what colour it is or how hot it is when washing. This prevents adding drying marks or swirls, water spots etc. And saves time. Water output figures will vary with your local water hardness, most people will achieve better results – this is based on medium hard Hertfordshire water.

Complete with 25 Litre of pure first grade MB115 ion exchange resin producing drinking water quality filtered water. Manufactured under ISO 9001 and ISO 14001 certification.

It is illustrated next to the smaller, standard 7 Litre filter, and stands approx. 1 metre tall. It will need securing to a wall to prevent it falling over, though our Water Filter brackets do not fit this unit.

We recommend that a final rinse is performed at half mains pressure, just sufficient to create a wave of water over the vehicle, and should be able to be completed in around 45 seconds for a standard family car, little over a minute for a 4×4. This is based on our own usage over the last 4 years.

Our resin vessels are made in Europe (many are not) and comprise a PE inner shell and wound fibreglass outer. These are high quality, strong units with best quality fittings and top grade resin.

These are heavy items and our low standard carriage rate is designed to keep costs down for customers of our standard size car care products. Shipping for these filters outside mainland England, Scotland and Wales is simply too much for us to absorb and unfortunately has to passed onto customers. Shipping to Northern Ireland for instance, for a filter alone is £25 in total. Please contact us if you live outside mainland UK.

The product is warranted free of manufacturing defects for 12 months, but the resin media is a consumable and not covered. If the vessel is dropped or falls, warranty on the cap and body is void.

    Why Race Glaze Water Filter 25 Litre?
    The answer is easy, water spots and 3 cars to wash a week. With a water reading of 270ph (Hard water) and using a jet washer it’s a no brainer. How after installing the Race Glaze filter 25L the reading I’m getting is 0ph. So straight away I jet wash 1 of the clean cars and left it wet. Checked later, car was dry and no water stops. It works everybody, it really does.
