Refillable 0ppm Water Filter (7 litre) - Description
We´ve all had to swiftly run round our cars to dry them before water spots form, which are very hard to remove and can badly affect paintwork. And try as you might, washing and drying will cause swirl marks and light surface scratching.
See video here: https://youtu.be/GCIaB-i91Tg
Suitable for use with a pressure washer but ensure you buy the £1 Mesh Exit Filter. Supplied ready to use with resin.
Existing in-line water filters are either very expensive or have incredibly short lives, and can waste the casing, which is very environmentally unfriendly. For example, the AquaGleem filter is 2.5 litre capacity, typically retails at £55. That´s 54% more expensive than our unit costing you 38p per litre. The Race Glaze unit costs 25p per litre, as supplied with its first fill of mineral-absorbing resin,and only 10p per litre with subsequent refills
NOTE: this is based on Harpenden town water at 420ppm - some of the worst in the UK. Most customers will achieve significantly greater volume of pure water than this.
The new Race Glaze Maxi-Filter uses a durable 11 bar pressure tested fibreglass tank ready filled with 7 litres of premium A1 grade resin (note: some budget filters use sharps - broken reject resin, or are only part filled) and comes ready for you to add standard Hozelock-type connectors (not supplied but available on this website) to begin use immediately. Not made in China or India - made in Belgium, so quality and durability guaranteed.
Mains water comes into the unit and is distributed out from the top strainer into the resin bed, falls under pressure and gravity down through the resin bed and as its only outlet is into the bottom strainer and up the pipe, comes through the resin bed to emerge on the outlet side as close to 0 parts per million (ppm) of dissolved solids as possible.
Using a hosepipe to wash a car uses approx. 30 litres of water (AutoExpress 21/3/2012), a final rinse only a fraction of that - we estimate 5-7 litres at most.
This is a breakthrough in filtered water product for car washing that is proving to be very popular.
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 4x4. This is based on our own usage over the last 4 years.
Accessories: Water Hardness Meter so you can test the water to see when resin needs replacing, and replacement resin in 7 litre or 25 litre bags. Alternatively, simply send us a sample of your output water and we'll measure it for you and report by email. FREE service for our customers only.
All our figures are based on a sensible typical UK hardness figure of 300ppm dissolved solids in Hertfordshire, giving 415 litres of water. You will get much more in softer water areas.
OUR PRODUCT REVIEWS There are dozens of reviews of these products and every one is totally genuine. Customers love them ! The product really is that good. If we added all the good things said about them verbally and on Forums we'd have 3 times as many...
We have carefully selected these taller vessels, in consultation with a water treatment industry veteran, as wider, dumpier (window cleaners) vessels have a lower efficiency and can´t extract the maximum capacity from the resin. This ends up costing you more money. In our tests, our 7L filter produced 59 litres water per litre of resin, over 20% more efficient than the window cleaner 10L unit which produced 48L per litre of resin. So if you're comparing units, add 20% to the price of the dumpy units.
We strongly advise that you check your shed/garage for male adapters and hosepipe-end connectors prior to purchase - though you can buy them from us with your order.
WILL WATER SOFTENERS DO THE SAME THING? Water Softeners change dissolved hardness into dissolved sodium bicarbonate which removes limescale. However, if you boil off the resultant water you will have a residue at the end of the process - which will be left on your car if you use softened water to wash it and let it dry in the sun.
Our filter totally removes all dissolved solids and there will be nothing left on your car after sun drying. They are different process designed to do different things.
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.
NOTE ON SHIPPING OUTSIDE MAINLAND UK 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 delivery areas of 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 £15 and with extra resin, is £22 in total. Please contact us if you live outside mainland (lowland) UK - the zones where you know couriers charge more to deliver!
WARRANTY 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.

More Customer Reviews of Refillable 0ppm Water Filter (7 litre)
After years of washing and drying got bought this as a Birthday present. It actually works, not an expensive gimmick. Washed and rinsed as normal then did a further rinse and left to dry. The hardest thing was resisting the urge to dry as normal, but it dryed naturally without a mark. Well impressed, time will tell how long it will last before the need for a refill.
You Need This Filter by Jay Green, Essex, 17 May 2020
I detail cars in all weather. When it's hot, water spots are your worst enemy, this fixes that problem. I wish I had one a long time ago!
Been using these for ages by Wayne Austin, Barnsley, 16 May 2020
Does exactly what it says it will do, works flawlessly have recommended people buy them I live in a really rubbish hard water area where river water is used so that leaves water spots all over the car, with the Race Glaze... nothing not a trace.
Time saver by Steve Capper, Bicester, 10 May 2020
I live in a very hard water area, have a large red car with black wheels, only using the filter to rinse the car at the end of my cleaning routine brought impressive results. No marks at all on the glass, shiny black wheels or indeed any where. Saved so much time as there was now no requirement to clean the glass and wheels. Car looks shinier, probably because the water had no contaminates in it. Very impressed, well worth the money
MARVELLOUS MACHINE !! by B M Young ., Cumbria ., 18 November 2019
Great result on a BLACK car .
Oppm filter by Lee, Locks Heath, 06 July 2019
Amazing product. Does great job wish I’d got one years ago
Had for a year ... by Peter Lack, Berkshire, 02 July 2019
Exceedingly hard water here. Wash a black car and leave it and it looks like someone blew icing sugar over it.
This really works as a final rinse.
The filter is nearly due for a change. But pretty good as I did wash the wife’s 27 times as well. I was expecting 35 washes and have got 45 crystal clear rinses and circa 10 more, that are still pretty limescale free. S class Coupe has a lot of square feet to rinse.
Shame the refills are expensive ... but definitely worth it. Well, its essential if you live here
No idea how to do that :/
Excellent Product by Bob Reynolds, Hampshire, 27 June 2019
I live in a hard water area and washing my Basalt Black Porsche 911, especially during the summer months, was very difficult as there were always water marks left even after careful drying. This product is amazing, I used it for the final rinse after washing and just left the car in the sun to dry. The car was gleaming and not one water mark in sight. I would highly recommend this product.
Too good to be true? by Allan Jones, Alderney, Channel Islands, 26 June 2019
When I saw reviews for this product I though it was too good to be true but bought a filter anyway on the off chance that it would work, just can’t believe it works as well as it does, just rinse the car with filtered water and let it dry. No spots, no streaks even in bright sun, saving all that tedious chamois leathering, an excellent product
Spot on (and off!) by Mat, Essex, 23 June 2019
As per all of the other reviews this product works exactly as advertised. Washed the car on a warm overcast day which would usually dry up with streaks before I have a chance to get round the car and dry it off. A quick rinse with the hose through the race glaze filter and you can towel dry the car at your own leisure. I can’t speak for how long the resin will last until it needs replacing but a bit of trial and error and I’m sure you can limit how much you use. Buy it!
Was sceptical but I was wrong! by James Griffiths, Shropshire, 04 August 2018
I was very sceptical when I purchased this despite the good reviews. However, I was shocked at just how well it works.
Testing my tap water with the TDS showed our water was 233PPM. After running a few litres through the filter it showed 0PPM.
I've just washed the car as I would normally (pre-wash, 2 bucket etc etc) and only used the filter for the rinse stage at the end using an open hose. I'm literally shocked by the results. Absolutely no water spots at all.
Wish I'd purchased it sooner!!
Best results in over 30 years of washing my cars! Incredibly impressed! by Steve Davenport, Hampshire, 07 July 2018
I wanted to test if the claims being made about the filter were accurate in all of the other reviews I'd read so this morning I washed my silver Golf and my wife's gun metal Mazda CX-5 in direct sunlight and temps pushing 30 degrees. The neighbours thought I was mad.
Could have ended in disaster but to say I'm blown away with the results is an understatement and I near on halved the time I would usually take and with far less effort.
For info, our unfiltered water out of the tap is 300 ppm. Out of the filter directly it's 8 ppm and with the hose attached and flushed through, the reading is 25 ppm, indicating mineral deposits within the hose.
The Golf was washed first with Megs Ultimate Wash & Wax, (two bucket method), rinsed with tap water and then immediately a second time with the filter attached. Left the car to dry naturally and the results to both bodywork and glass were outstanding with no additional wipe down required. What impressed me even more was that the surfaces were hot and drying quickly as I was washing, leaving the usual unsightly marks. However the rinse process sorted that and left nothing behind. Amazing!
The Mazda was subject to the same process but, being a darker car, some water marking did remain visible after natural drying, which wasn't completely surprising considering my 25 ppm reading. However a very quick and gentle wipe down with a damp microfibre, (rinsed in filtered water) returned an unmarked, mirror finish.
Both cars looked like they'd just come out of the showroom!
In a nutshell, I'm blown away. This product works for me, saves a significant amount of time and effort and I wish I'd considered it years ago!
Next up the ultimate challenge. My Basalt Black Porker. :)
Game changer! by Ben, Berkshire, 07 June 2018
Wow. Why didn't I buy one of these sooner? I've had black (and dark) cars for ages and water spots have always been a real problem. Usually I'd have to rush around with the drying towels and no matter how quick and well I do the job, there is always spots and streaks due to the hardness of our water here in rural Berkshire.
First time out, washed the car as usual and did a good and comprehensive final rinse with the filter inline to the jet wash. Left it to air dry for half an hour and came back to a literally 100% spotless finish. I am moved to tears! Highly recommended. A+++
Totally agree with reviews by James Page, Abingdon, Oxfordshire, 05 June 2018
Just to say how pleased I am with your 0 ppm water filter. As others have said, it makes all the difference in washing the car - the avoidance of water marks and the consequent time saving make a huge difference. I wish I had bought one sooner.
Excellent by Michael Jackson, Hull, 25 May 2018
Thanks for sending earlier in week,very efficient!, was up and working within five minutes of receipt!...excellent for my wrapped R35.
Raceglaze water filter by Joe, Norwich, 16 October 2017
Used it at the weekend on my black rs focus and all I can say is wow
Why didn't I get one sooner? by Steve, Swadlincote, 16 June 2017
I've just washed 2 black cars in hazy sunshine.
Rinse with tap water, wash with Meguiars ultimate wash and rinsed the suds off with filtered water. Instead of doing the usual and drying the cars manually, I deliberately left both to drip dry with no intervention from me.
And....there's not a mark - nothing, on either of them.
I'm seriously impressed. Usually I'd have to wax the cars each time they were washed to get rid of the marks. This filter will pay for itself in saved time and the polish / wax you won't need to buy so often.
Product test by Dave, Solihull, 18 April 2017
Purchased this on advice from a detailer, and I am extremely pleased with the results. I washed my car as usual and just rinsed it off with water through this filter. Left it to dry naturally and couldn't find a single water mark. I've already recommended it to a few friends.
Excellent but be prepared by Chris, Wiltshire, 09 July 2016
I love this filter and it really does work as advertised. I have been using it for over a year now. I would definitely advise anyone who gets one to also invest in a low cost TDM meter and regularly test the PPM of the produced water. Because in my experience the filter media lasts for a good while but it goes from 0ppm to 200ppm in a very short space of time indeed and the first time you will realise the media needs changing is that your car is covered in horrible water marks that are a real pain to get off. (RG Comment: users will note light spotting appearing in a few rinses before this collapse of performance)
Great product by Barry Danylew, Uk, 16 May 2016
Recently purchased a 7 ltr water filter, arrived on time, great product would recommend it.
Truly amazing by Tony, Lincs, 09 May 2016
Convinced by reading all the reviews I purchased one and it is truly amazing not one water mark left on a black car. My friend who was watching could not believe how it dried spot free & said its convinced him to buy one.
Price and delivery were excellent as usual by Martin Ritchie, St Albans, 10 February 2016
If you want pure-filtered water to give your vehicle a final dry-free rinse then this is the kit to use. The Raceglaze 7 litre water filter is much cheaper per litre of water than Aquagleam units you can buy (which have leaked filter resin with the water when I used to use them before discovering Raceglaze water filters).
Initially dubious... by Russell Du Lieu, Salisbury, 09 February 2016
I went for this product on the strength of the reviews but was still dubious about it being able to perform as described. I washed my gleaming metallic black XKR (in the evening sun) and then rinsed it off with the 0ppm filter - and then walked away. 1hr later no water drops and no water marks, brilliant!
An Australian review by Liam Kalas, Sydney, Australia, 24 December 2015
I’m absolutely loving my filter, now that Summer’s hit Australia it’s a godsend being able to wash in direct sunlight and heat without fear of waterspotting, plus it’s cut out the drying phase of my wash routine therein reducing the chances of marring. Thanks again for the awesome service during my order
Most amazing gadget by Garry Smith, Worcestershire, 16 October 2015
This is the single most amazing car cleaning gadget I have ever come across. My business partner has just bought one too. The reviews are true !
Amazing by Andrew, London Se13, 02 August 2015
I was fed up washing my car in the sun. My front drive gets the sun all after noon, spent as long getting rid of water marks then washing the car , so I ordered this from Raceglaze. Washed my car this Saturday in the sun (1st Aug 2015), used 2 buckets one for wash, one for clean water. I used the mains hose to prewash then washed and hosed down as I went, then in 15 seconds connected the mains hose via the Raceglaze filter did final rinse. I then washed my house windows and rinsed off ... When dry ,, well.. Amazing, so clean, no water marks . Windows the same - what a time saver ! 100%
Simply Fantastic!! by Daniel Cahill, Orpington, 30 June 2015
So the filter was delivered today, hottest day of the year so far, thought I'd give it a whirl on my jet black focus..... I must admit, I was apprehensive! No need to of been though, honestly I have never used a product so good!! The air temp must of been around 29 - 30 degrees, the paint work was even hotter and nothing, absolutely no water marks or anything, truly the best product I've brought as a detailing enthusiast! Excellent product and not to bad a price. Definitely worth buying!!!
Phenomenal performance ! by Peter Lawley, Telford, 08 June 2015
I have to agree with your own recommendations and the other reviewers, this product is outstanding and worth every penny. Thought I would take a punt on the smaller version as we live in Severn Trent area and I'm fed up with having to combat watermarking after washing the car - often with a proprietary dilute acid product. Deliberately just washed our red Audi A3 car on the hottest day of the year so far, pre-rinsing with a foam, via pressure washer, then rinsing off, and shampooing - all with the filter connected in line. Final rinse off with filtered water, and a final detail clean of the alloys whilst it dries off. Result - perfect finish as already commented before, no watermarking, no effort required. After the Audi A3, best buy ever. Just would like to find some 'fire extinguisher' type clamps to fit to the garage wall, but no luck thus far.
Does exactly what it says! by Stuart Smith, Manchester, 13 May 2015
Bought a Refillable 0ppm Water Filter from you a few days ago and used it last night, results were great thanks! No drying required and no spots, so does exactly what it says! Just one little question about storage after use - do I just leave it full of water or do I empty it out? [Leave it full unless storing for several months]
Sceptic convinced by Steve Heidukewitsch, Mansfield, 07 September 2014
Brilliant product no water spots no need to leather off even in bright sunshine. When you see so many good reviews you get a little suspicious but the reviews are good because the product is great!
Exceeded my expectations by David Chambers, Upton Newark Notts, 02 September 2014
It has been almost a years worth of using this amazing water filter the best £100 that you will spend on any cleaning product Porsche Basalt Black shows every water mark! But no more....in fact a pleasure to wash the car now even in bright sunlight!!
Better Than Expected by Ian Harman, Petworth, West Sussex, 23 June 2014
Used first on my wife's silver car and washed as usual, then rinsed off with filtered water. First batch left some crystals from filter (first use) but rinsed to leave little water that did not mark. Dried to glossy finish speeding up proceedings. Today have washed my black estate in full sun and washed, then had to go out unexpectedly so quickly rinsed with filtered water and left car in sun. Returned home to find shiny black paintwork with no water runs or marks. Later dried door shuts etc. and car was ready to go back in garage. Excellent result which will cut my time washing dramatically. My only suggestion for improvement would be some sort of carrying handle as it's a bit heavy when full of water and the natural place to carry it is via the hose connections which may prove to be a problem.
Best product ever by Jonathan Longden, Huddersfield, 03 March 2014
The best car cleaning product I have bought in my entire life. Wish I'd bought one years ago. It has rinsed and final rinsed my 2 cars plus the odd neighbours car, every week, for 7 months.
Brilliant - Amazing Product! by Simon Spall, Norfolk, 03 March 2014
Used my water filter for the first time yesterday, and wow, this product is amazing. If you don't own one of these yet, do not hesitate, the results speak for themselves. I was slightly sceptical, I just used the filter at the rinse stage (Pressure Washer), having washed the Discovery 4 in the normal manner, AutoGlym Shampoo and unfiltered water. I left the car to dry in the normal manner, unbelievable not a mark on it. I did leather the car off afterwards, just out of habit. The paintwork looks stunning almost glass like, the car looked like I had spent 2 hours waxing and polishing. This has to be the best item I have purchased in ages, I should of had one years ago.
Many, many thanks.
watching paint dry by Simon Rudderham, Littleport, Cambs., 09 February 2014
Thank you for the advise and the products you supplied me. I spent most of Sunday afternoon watching water dry from my car (like watching paint dry lol) not totally believing it was going to work. but what a good feeling I got when the water dried and left me with a high gloss,water streak free finish. I have sent you some pictures taken of my car left to dry naturally. Ps I wiped the windows though (habit)
Brilliant product and great service by Tony Blanks, Herts., 19 August 2013
I ordered a 7L water filter and it arrived the following day ... it doesn't get any better than that. I'd never used a water filter on my car before but it's one of those things from which I'll never go back. Apart from not needing to dry the car, the depth of gloss achieved after just one coat of sealant is amazing. The paint finish takes on an entirely new finish ... it's like someone has covered the car in a layer of glass. Brilliant product and great service from Race Glaze
Impressed by F10n47, Detailing World, 17 August 2013
I've been plagued with water spots after washing my car in the hot weather so I decided to try a water filter. Initially, I was going to buy an Aquagleam but then I saw the Raceglaze version which is refillable. I tried it for the first time today and to say I'm impressed is an understatement!
I didn't believe it could dry without any spots or streaks, but it does. Even more impressive is the finish it leaves. Compared to the filtered water, normal tap water seems to leave a film over the paint which obscures/dulls the shine. Once dry, the filtered water leaves the paint with a sort of smoothness which is difficult to describe. It feels almost like it's just been clayed.
I washed the paintwork and left it to bake in the sun (for test purposes) whilst I cleaned the wheels. I had to dry the last few drops off with a towel because I wanted to apply some Jett, but even before towel drying there were no spots or streaks to be seen. The Jett normally adds a slight amount of depth to the shine but after rinsing with the filtered water it looks totally different. It's far more glossy and the reflections are much sharper. I was going to take some pictures but there was a cloudburst before I could finish with the Jett
If anyone is thinking of getting one of these but is hesitating because of the price, find the money from somewhere and just get it! You will not be disappointed.
Good - 5 stars by Leighan Meddick, Blackpool, 08 August 2013
This product filtered a lot of the crap out of my water but it still left minor water spotting over the car. It was an improvement but I couldn't help but feel disappointed. Then I agitated the resin after speaking to Race Glaze and its now perfect - 5 out of 5 !
Thank you by Rory Burnett, Wiltshire, 05 May 2013
I used the Water Softener recently purchased from you today. It is 18-20 deg C full bright sunlight, 11:30 and I have just washed a black Mercedes SLK, rinsed it off with the water softener and walked away,by way of testing.
The result is unbelievable, our water is very hard in Wiltshire, 300+ppm and there is not a single spot on the car! What a brilliant product, very many thanks
Amazing! by James Weaver, , 06 October 2012
Been looking into water filters for a while and decided this was the one to try. What can I say but this thing is amazing!
Washed my RS today in direct sunlight, connected to my pressure washer and no loss of water pressure whatsoever! Used it to fill my buckets and for final rinse.
Left to dry in the sun and not a single water mark onit at all! Can't recommend this product enough! I've just had the car detailed so want to touch the paintwork as little as possible, this product is ideal.
Sceptical - until I used it - amazing ! by Gareth, Grimsby, Lincs., 24 September 2012
Collected one of these from Mark on my way home from work yesterday. Have to admit I was a bit sceptical as to how good it would be but I went and bought the hose connectors this morning and then tested it on my red Audi S5.
Washed the car as normal then put the filter in line with my pressure washer for the final rinse and left it to dry.
Not a mark on it
Moved on to the F430 and same result. Brilliant
This has to be one of the best £99s you could spend. Everyone should have one.
Not one single water mark by Arron Chandler, Folkestone, Kent, 11 August 2012
OK, so I used my filter for the first time today.....
Insect remover on the front end, 2 bucket method, filtered water in the rinse bucket, hot tap water with Auto Glymm shampoo in the other.
Cleaned the car in stages - front/middle/back, rinsing very thoroughly with filtered water through a hose as I went.
It was a blazing hot day here today so I just left it to dry in the sun - usually a recipe for disaster.
Not one single water mark...........
