In order to get the most out of your SteriPEN Adventurer, you may also want to check out these excellent accessories:

 

SteriPEN Water Bottle Pre-filter

The SteriPEN Water Bottle Pre-filter is a good option when there is no clear water, so you need another level of water purification before submitting it under UV light. This SteriPEN Pre-filter strains other particulates from contaminated water. It also fits wide-mouth water bottles, like the NALGENE Tritan Wide Mouth BPA-Free Water Bottle. ($11)

 

 

 

 

 

SteriPEN FitsAll Filter

The Steripen FitsAll Filter efficiently strains more particulates from untreated water because it uses a durable 40×40 micron screen. The design includes a filter cup and funnel fit that can be used to all sizes of bottles, whether wide- or narrow-mouth ones and even soda bottles. It is flexible enough to be stored in tight packages and storages. ($14)

 

 

 

 

 

SteriPEN Adventurer Opti with Solar Charging Case

The SteriPEN Adventurer Opti with Solar Charging Case is a SteriPEN Adventurer along with a solar charging case. This device can charge two CR123 rechargeable batteries in no time. It only weighs 5.7 ounces so it is light to carry, too. The solar charger has its own neoprene carrying case, plus an AC adapter for charging indoors. ($120)
