LARQ Bottle PureVis
The LARQ Bottle PureVis is a market-leading self-cleaning water bottle with a built-in UV-C cap, ideal for backpackers who want one integrated solution for storage and purification without separate devices. It trades the lower weight and versatility of handheld SteriPEN units for the convenience of autonomous cleaning and a sealed bottle system, which can justify its higher upfront price for users prioritizing simplicity and hygiene. For multi-day trips where storage and purification in one unit is preferred, the LARQ stands out despite the weight and cost premium.

Review Summary
"Owners like the LARQ Bottle PureVis for its convenience, taste/odor improvement, and daily self-cleaning UV feature, but backpackers often find it less suited to very turbid or high-risk water and criticize battery life and higher cost. After extended use people appreciate the hands-free aspect but caution it’s not a catch-all for all field conditions."

CrazyCap Pro
The CrazyCap Pro converts existing bottles into UV-C purifiers via a screw-on cap, offering a modular, often lower-cost alternative to purpose-built bottles and an easy upgrade path for backpackers who already own lightweight containers. Compared with the LARQ PureVis, CrazyCap Pro typically delivers comparable UV functionality at a smaller price and with more flexibility, though it requires a compatible bottle and may lack some integrated bottle features. It's a strong choice for hikers who want the convenience of UV treatment while keeping their preferred ultralight bottles.
