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.

I am at your mercy as whether the water is clean or not. A regular meter does not detect everything but the TDS tester does not show any improvement.

The CrazyCap 2 Value Pack seems to be a great product. It’s a quality water bottle with a UV cap. The bottles and the caps seem to be living up to the provided description. The stainless steel bottle keeps beverages cool, as stated. We fill our bottles with cold water at our 9pm bedtime. When we wake up between 5-6am, the water is still deliciously cold. As far as the actual purpose of my purchase: the UV cleaning capabilities, I’ve “only” been utilizing the UV cap for about 14 days. During this time, the stainless steel does get build up around the interior of the mouth piece (easily washes off). However, the build up isn’t accompanied by the typical unpleasant scent I’ve had with the average, non UV stainless steel water bottle. I was previously utilizing an average stainless steel bottle with a typical cap closure, for about a year. Unfortunately, despite regular washings, deep bleachings, and peroxide cleanings, my previous bottles had a significantly unpleasant scent. This scent was almost bad enough to where I considered never ever using a stainless steel bottle again lol. So I did some research and found CrazyCap. I took a peek behind the scientific evidence of UV light in regards to disinfecting capabilities in regards to water. The research seems to provide positive findings of effective results. So I took the plunge and orders this value pack. There’s a few less than positive aspects, but these are likely fluid, and just from my personal prospective: 1). Cost/Value could be greatly improved. The cost for the CrazyCap 2 Value Pack almost made me decide to pass on this purchase or keep looking. Fortunately/thankfully, I found a promo code that helped a tad, but still… I caught myself wanting to under exaggerate about the costs of this purchase when a family member asked me about the cost of the bottles. I wanted to say “$50 per bottle with the cap” but didn’t want to fib lol. The family member was shocked in regards to the cost of the bottles (more than $50 each). I think $50 each would be a comfortable price point for 1 stainless steel bottle, with 1 CrazyCap. At that price point, I would make this purchase again, with much less hesitation. A typical/standard stainless steel bottle is about $12.50 each (a set of 2 stainless steel bottles with typical caps is about $25 at a wholesale store near me, with free shipping at Sam’s) - The water holding capacity could be improved. I feel this bottle would be better if it were to provide a 24-32 ounces holding capacity. However, these bottles may have a certain capacity limit due to strategic purposes like providing a more universal fit on other bottles perhaps (and maybe there’s already a larger size available). Other than these things, I’m enjoying this purchase and would recommend this item to others, but only if they’re comfortable spending at this price point.

Can't say enough good about this or the company

As a hiker and backpacker this will be an amazing way to cut back on toting my water. This will allow me to fill my water from our many mountain streams and waterfalls! Great design and concept. Recharging will be easy with my portable charger! Great customer service!

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.
