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.

The best water bottle you can buy

This is an amazing company, their products are state of the art. They use the same UVC-LED light that hospitals use to sterilize there equipment. Which kills germs at 99.99 percent. It has different features on it for a quick clean and a longer clean for river water or water that you think is a little sketchy and it self cleans. Their customer service is top notch, I've never been let down by them. A really good product with a great company to stand behind it.

Peace of mind

I'm so happy I bought my new water bottle. The 25oz model fits in my car cup holder which is actually more convenient than I thought it would be. My last water bottle wouldn't fit anywhere and just sort of rolled around the car. Using the cap is also very straightforward and simple and I love that I can use it to sanitize surfaces as well! I would say the only drawback is that this particular finish is a bit slippery and I have already dropped it a couple times, so the carrying handle is probably a worthy investment. Looking forward to more clean water and a bottle that's always clean too!

Excellent Bottle, Excellent Buy, Just Excellent Overall!

I'm absolutely loving this bottle! Might need to grab another cap so I can continue using it while the other cap is charging! Water tastes great, and it's impressive how long it stays cold. I take this everywhere I go!

Cap lost ability to charge after only 3 months

I love the look of the teak bottle, very sleek. Overall I love the idea of the product and being able to sanitize on the go. However, I question the quality of the product. After only 3 months, the cap does not hold a charge and therefore you cannot sanitize water. I contacted customer service, and they are sending me a replacement cap. Let's hope this one works better than the first! However, they are charging me $6 shipping on the cap. It's a small dollar amount, but it feels super tacky when the product is under warranty for 10 years, and the cap stopped working after only 3 months! I was told by customer service the shipping is managed by a 3rd party, (isn't all shipping managed by a 3rd party???) And there was no way they could ship the replacement cap for free even though they offer free shipping on new purchases. I was so excited when I first heard about the product, but I can't say I would recommend this 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.
