What's TT and why don't they think MSR tests their stuff adequately?

The new HyperFlow filter was tested for 3+ years before it was introduced to the public. We weren't the first on the market with Hollow Fiber and believed that it needed more testing than our competitors. We test in labs with two types of water (sample 1, typical backcountry water; sample 2, worst case senerio water which is impossible to find in the backcountry anywere). We make absolute sure that both types of water can be filtered depending on the specs of the filter or chemical.

We test in the field for the 3 years mentioned above. We use the military to help us test. By the time we are ready to manufacture it it has gone through thousands of hours of testing both in the lab and in the field. The HyperFlow is rated to ABSOLUTE 0.2 microns which means that anything smaller than 0.2 microns can't get through the filter (depending on the concentration). This is similar to all of the filters on the market.

Sometimes we delay production (i.e. The Reactor) if we find issues in manufacturing. This has been the case with the HyperFlow based on supplier issues. Rest assured when it hits the market it will be as perfect as humanly possible based on our extensive testing. One thing I forgot to mention is that we employ full-time microbiologists who work at our R&D facility in Seattle. They are constantly testing production product and making sure it is viable. We also manufacturer all of our filters in our Seattle facility. There is a lot of oversight and redundancy in how we test and manufacturer.

We don't claim that we can take out viruses mechanically. We believe that First Needs, who has passed the EPA protocol for virus removal, only passed this in a lab. They use positively charged viruses that are attracted to their negatively charged carbon matrix filter. The unfortunate thing is that not all viruses in the backcountry are positively charged. In a lab it works, but in the real world you can't be sure.

All filters today will treat to at least 0.4 microns which is enough to get out giardia and bacteria, the two most threatening bugs in water. Viruses are not as prevalent, and only are concerns outside the USA. If you are worried, simply add a few drops of MSR Viral Stop (diluted sodium hypochlorite) per liter and in 5 minutes you will have virus-free water without the chemical taste.

Did those who made these comments on TT(?) have a reason or a past problem with MSR? Did they have a bad experience, or are they simply clueless?
