DI Resin (Deionization Resin)

Which resin is best for me, XERO Virgin Resin or XERO DI Resin?

You won't find a huge difference between the two options. Both allow you to buy in bulk to save, and if you're working with a multi-stage system like the XERO Pure, you'll barely notice a difference. But head to head the Virgin Resin will last a little longer in a standard DI Tank. The Virgin Resin is brand new and has never been used so therefore it is a little more expensive. XERO DI Resin is once washed and the more affordable choice. It was used at some point before and then regenerated to be used again with only a slight loss to efficiency.

Window Cleaning Resource carries DI tanks and replacement DI resin which is essential in creating pure water for waterfed window cleaning. DI resin can be used as a standalone filtration system or it can also be used as the final step in a multistage purification system, such as any of the XERO Pure Water Systems for example. Your TDS (Total Dissolved Solids) plays a huge parts in determining how long your resin will last. If you have a higher TDS, the lower upfront cost of a DI only system may seem attractive but you have to consider how much faster you will burn through resin. A Multi Stage System costs a lot more up front but you will be changing the DI resin much less frequently and it will cost less. Bottom line: if you have a higher TDS the multi-stage system is a much better investment in the long term. However, if you have soft water or are an infrequent user, a standard DI tank, or other Single Stage System may be a suitable option.
