Science behind Portable Water Purifier
We have run meticulous laboratory tests to ensure our UV Light in our portable water purifier makes water from ANY source (free of debris) 100% safe to drink. See the full labĀ report here.
CrazyCap uses advanced 278nm deep UV LED to effectively sterilize water. See the charts above showing a significant reduction of bacteria in the contaminated water in both Normal and Crazy Mode Sterilization. The spectrum (260nm to 280nm) of light is found to have maximum disinfection capability.
Thanks to the recent development in LED technology, this special spectrum of light can now be produced without using toxic Mercury. When the Deep UV light enters the microbial cell, it destroys the active core (nucleic acids). Cells without the active core will no longer be viable.

It was easy as pie.

Beautiful product that works as intended. I just wish the filter actually made a noise as it connected to the cap it also makes a noise because of how dense the filter is (purist). I love this product nevertheless.

It took too long to receive the product.

Sadly the light indicator has a nudge which kind of ruins the premium experience also this being a new product, one that was expensive to buy and had to wait for a long time. The filter I used (Artesian) tends to make a weird noise when sucking water through it. No biggie there, but it's noticeable. Other than that it works as advertised so it's an acceptable, if a bit expensive, product.

Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
