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.

Company Response

Hi Steph,

Thanks for sharing your wonderful feedback with us and the community. 

Yes, you are absolutely right on average we spend $500 per year on the bottled water, which has a huge impact on our economy and the environment. 

CrazyCap costs less than 0.001 per gallon of treated water providing up to 8 million ounces of drinking water. 

If there is anything else we can do to help, please let us know.

Cold and clean water

I purchased a crazycap bottle some months ago and its held up fairly well so far. It keeps my water cold for hours and the charge on the cap itself seems to last a long time too.

Best purchase ever

I liked it so much I had to buy another one for my daughter when she saw mine. This works very well. Recharging instead of changing filters is a nice thing.

Love this water bottle

I saw this water bottle on the Rachel Ray show. I purchased one when I received it it was damaged. So I contacted customer service and they mailed out a replacement right away. I take this water bottle everywhere I go I work at a school so it gives me a peace of mind knowing that my water bottle is germ free. I would definitely recommend this water bottle to anyone.

Satisfied multiple needs.

I stumbled upon Crazy Cap because I was looking for UV sanitizers due to our COVID infused world. I purchased this for my mother. She lives in Florida and the water seems terrible. She double filters the water before using it to cook or drink. Unfortunately filters only remove contaminants and do not sterilize the water. I’m not worried when she cooks with it but was apprehensive about her drinking it. Seeing a product like this was like a ray of sunshine on a cloudy day. It was immediately purchased the minute I saw it. Not only does this product disinfect her water, but any other item she or I choose to shine the cap on like a phone or keys. It handled my original need and found a resolve for my concern about her house water. Purchasing this product seemed like a no brainer to me. I’ll admit that the instructions to the bottle were cursory to me and I had many questions regarding its use. I contacted the company and had my questions answered with expediency and insightfulness to cover things I hadn’t thought to ask. I appreciate Kristina Miles diligent efforts. She followed up with an email covering the points of our conversation so that I wouldn’t forget. Great customer service with an extremely useful product. While I don’t see the need to disinfect lake water because we don’t hike and due to COVID we are social distancing to the extreme, it is comforting to know that we could drink disinfected water without boiling in our daily lives and in an emergency while also being able to disinfect every day use items. I am very pleased with this product and customer support so far. It has been less than a week that this product has been used and I wrote this review.

Santa F - 06/25/2020

Was unsure, but feel very different now

I'm a pretty new user, but I have to say that I feel so much more confident in the quality of my water. Typically I'd leave a reusable bottle in my car for weeks, and wonder if it was still okay to drink. I'm better about that now, and since using the CrazyCap, I feel confident mu y water is really clean.


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.
