Platypus GravityWorks vs GRAYL Ultralight Compact Purifier/Water Bottle

Analysis:

No sources that perform objective hands-on testing have deemed the Platypus GravityWorks 4l worthy of being included in their Backpacking Water Filter roundups, which typically isn't a good sign.

Taking a look at the GRAYL Ultralight Compact Purifier/Water Bottle, we found that it hasn't managed to perform well enough to earn a spot in any Backpacking Water Filter roundups done by sources that conduct their own, high-quality, hands-on testing. That alone makes it difficult to recommend.

As a last step, we wanted to do a head-to-head Platypus GravityWorks 4l vs. GRAYL Ultralight Compact Purifier/Water Bottle comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
