The MSR Miniworks EX Microfilter works well by itself, but these accessories will prove to be good complements to the filter.
MSR Water Filter Maintenance Kit
Although the Miniworks EX can easily be detached and assembled anywhere, it makes sense to have a kit of spare parts plus a tube of silicone coating to make sure that the filter is always at its prime. The kit includes extra O-rings, stoppers, instructions, and a portable carry case—all weighing just 2.4 ounces.
MSR MiniWorks EX Ceramic Element
Since the fragility of the ceramic filter is the most common issue with this model, bringing along an extra is indeed a helpful and practical tip. This works just like the original and even works on WaterWorks models.
MSR MiniWorks EX Replacement Hose

Lost, punched, bent or for whatever reason, the MiniWorks EX Microfilter’s hose may be damaged. For such instances, the company sells a replacement hose so users will end up spending less than buying the whole thing.
MSR MiniWorks Microfilter Cleanside Cover

To prevent contaminating filtered water when the cover cracks or is damaged, a separate cleanside cover can also bought for replacement.
