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 lab 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.

As advertised, great fresh water bottle.

Cold, fresh-tasting water through two refills. I would buy a larger one next time. This one is perfect for my nightstand.

Overall if you can afford it, it’s a worth buy!

Overall I love the product and it works great. There’s only some improvements to be done to be excellent: - Sometimes the sensor bc is a touch sensor, it doesn’t detect it perfectly. - Charger is really bulky and there’s no option for USB-C. - A little bit expensive. I paid it because there’s no alternative on just caps and love the vision and want to support the founder to continue working on this.

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.
