Meet the new generation of
XERO Pure Water Systems!

  • XERO Pure

  • The XERO Pure features an updated design inspired by the tried and true XERO Pure! It's an affordable, easy-to-use, three-stage purification system that is great for beginners, residential or commercial window cleaners. The three-stage stages of purification include Carbon, RO, and DI. Built-in house, it is durable, lightweight and easy to transport. It can handle soft or hard water and have good pressure at 2-3 stories (check your TDS here to find out what kind of water you have).

    This is our most economical and affordable system and is great for running one pole at 30' to 40'. It comes loaded with all the filters and fully assembled, pre built right out of the box so you are ready to get to work.. Need to run two poles or need a little more power? Scroll down to check out the XERO Pure MAX.

  • XERO Pure

  • If you like the sound of the XERO Pure but are tight on space, consider the ATOM! Both units work exactly the same and produce the same amount of water but the smaller size of the ATOM is convenient for smaller work vehicles. What differentiates the two is the two 21 inch membranes instead of the single 40 inch. This gives the ATOM a height of 40.5 inches instead of 52 inches and a weight of 52 lbs. This unit has three stages of filtration and non-proprietary filters. Super user-friendly, reliable and of course, compact.

  • The XERO Pure MAX is a powerhouse of a high flow system! Need to run two poles? Want something you won't outgrow? If you simply want more water flow, this is the unit for you. The dual ROs on this unit produce 1 gallon per minute allowing you to work without a pump on high windows. Easily run two poles at once for those big jobs. This unit can handle the hardest of water and help you tackle up to 4-5 stories with ease. If you're tight on space and need something more compact, scroll down to check out the XERO Pure ATOM.

    Single-Stage Systems

  • If you have a lower TDS (Total Dissolved Solids) and work in areas with softer water, are a solo operator, or are only planning on using your new setup infrequently, a single-stage system might be for you! A general rule of thumb is if your TDS is under 100, a simple DI tank-based system would be the most cost-efficient for you.

System Maintenance

The World One system has been transitioned over to the XERO Pure brand name.
The process for maintenance is the same!

  • You can't take this system straight out of the box and take it to a job, It's extremely important that you let your RO Membrane saturate before use! If you don't, you won't be able to achieve the results you want and will be exhausting your DI Resin. Sometimes, it can take up to 12 hours for the RO Membrane to fully saturate!

    To properly saturate the RO Membrane, hook your system up to a garden hose and let the water run through it for 10 to 15 minutes. Turn the water off and let it sit. Ideally, let it sit overnight so the membrane has plenty of time to saturate so your system will work as it's supposed to!

    Note: RO Membranes can vary in the time they require to become fully saturated.

  • Maintaining your Carbon Pre Filter is extremely easy! We provide the tools you need to replace your filter, so you can keep your filter in tip-top shape. You should change your filter whenever you get a clog or there is a significant slowdown in water production.

    Simply loosen your filter housing using the provided filter wrench, you won't need to turn it far since the housing isn't too tightly in place. Take off the bottom of the housing, take your old filter, toss it out, and pop in a new one. Use the supplied lube to lubricate the housing o-ring seal, then put it back on your system.

    Caution: You do not need to tighten this housing down anything beyond a snug fit. Do not overtighten!

  • Your TSD Meter will tell you when your DI Resin is spent and needs to be changed. You should always change your resin at 10 parts per million, any further and you might end up going back to clean spots off the windows left from water that isn't 100% pure.

    Use the larger filter wrench that is provided to loosen the DI housing from your system. The bottom portion will come right off and inside is your refillable DI Cartridge. Unscrew the top of the cartridge and remove the foam filter. Clean out the old resin, put in some nice fresh resin, and you're ready to go!

    Note: It's important to lubricate your o-rings before resealing any filter housing.
