What is California Proposition 65?
Do any of your water storage products contain BPA, BPS, or use polycarbonate?
Why is backflushing so important with the GravityWorks™ filter?
You must backflush regularly to maintain optimal performance of the filter cartridge. This is especially true in murky or very silty water. Since Hollow Fiber is not a depth-based media like ceramics, you don't clean by removing clogged material from the exterior of the filter media. Instead, you must rinse the particulate that collects on the outside of the Hollow Fiber membranes. Infrequent backflushing makes the particulate harder to remove and more difficult to restore the media’s flow capacity. Based on results from our in-house bio lab, we recommend backflushing anywhere from every 8 liters to after each use, depending on water quality. Our lab has found that the more you backflush the better your flow performance, and the longer life you can expect from your filter cartridge.
The easiest way we have found is to do it every time you fill your Clean reservoir. Just disconnect the hose from the Dirty reservoir and hold the Clean bag high for about 4 seconds. That’s all there is to it.

How does the GravityWorks™ filter do with tea-colored water?
This color of water typically comes from a high concentration of decaying vegetation adjacent to, or in, streams and lakes, resulting in a variety of organic acids. These include, but are not limited to, tannic, fulvic, and humic acids. These acids and the accompanying water conditions are very hard on ALL types of water filters.
Get your water elsewhere if you can. However, if no alternative exists and you are predominantly filtering these waters, we recommend using an MSR® MiniWorks® EX filter. Its ceramic element will collect all these impurities in its outer-most layer, allowing you to scrub away the clogged portion to restore normal flow rates. If you must use a GravityWorks™ filter, backflushing religiously and often will help to minimize the effect of these impurities. When you return home, add 2 drops of unscented household bleach to one liter of water and backflush this solution through the filter. This will help to break up organics that might be clogging the filter while also providing the recommended treatment of your system for long-term storage.
Limited use in these conditions will not have a dramatic effect, but extended use can permanently impair hollow fiber media.

What about freezing?
Once you have used your GravityWorks™ filter and wet the Hollow Fiber filter media, the fibers will still be wet. Therefore, it is important to prevent it from freezing, which can permanently damage the filter media. If you are traveling in areas where you are expecting freezing or near freezing temperatures, bring the filter into your tent, or even your sleeping bag. (Be sure to put the filter in a water tight bag to prevent leaks in your sleeping bag.) If you think your filter may have been damaged by freezing, perform a Filter Test before the next use.
For expedition-style travel where freezing temperatures are the norm, we recommend using the MSR® MiniWorks® filter. Its ceramic/carbon filtration media is better suited to such conditions.
Are consumers using a Platypus product with a Proposition 65 warning at risk?
The California government states: “The fact that a product bears a Proposition 65 warning does not mean by itself that the product is unsafe.” The government also explained, “You could think of Proposition 65 more as a ‘right to know’ law than a pure product safety law.”
A Proposition 65 warning means that the product contains one or more listed chemicals. By law, a warning is required unless the business proves that the exposure to the chemical poses "no significant risk." The "no significant risk" level for carcinogens is defined as the level which is calculated to result in not more than one excess case of cancer in 100,000 individuals exposed over a 70-year lifetime. Therefore, if you are exposed to the chemical in question at this level every day for 70 years, theoretically, it will increase your chances of getting cancer by no more than 1 case in 100,000 individuals so exposed.
The "no significant risk" level for reproductive toxicants is defined as the level of exposure which, even if multiplied by 1,000, will not produce birth defects or other reproductive harm. Therefore, the level of exposure is below the "no observable effect level," divided by 1,000. (The "no observable effect level" is the highest dose level which has not been associated with observable reproductive harm in humans or test animals.)

Can I put other beverages in my Platypus bottle or reservoir?
What if the filter takes a hard drop?
We don’t recommend removing the protective bumpers (GravityWorks) or removing the Filter Cartridge from the protective housing (CleanStream). The bumpers on the GravityWorks™ filter are designed to protect the Filter Cartridge from most drops, but direct drops onto cement and any drops above 5 feet (1.5m) should be avoided. If the Filter Cartridge itself is ever dropped after being wetted and outside the protective housing, you should replace it. If you think your filter may have been damaged from a drop, perform a Filter Test before the next use.
How do I disinfect my Platypus bottle or reservoir?
Is there a way to filter into my reservoir without removing it from my pack?
Yes. Simply remove the bite valve on your hydration system and connect the end of the hose directly to your filtration system’s outflow port. Using a GravityWorks™ filter system, your reservoir can take the place of the supplied Clean reservoir, creating what is arguably the lightest, most compact and efficient way possible to get water. GravityWorks™ filters are available with direct-to-reservoir and direct-to-bottle adapters for optimum versatility.
