Cleaning & First Use

Our reservoirs are manufactured to high standards and are made from taste-free food grade TPU material. However, it's always a good idea to clean your reservoir when you first receive it, and after each use.

Best cleaning methods:

• Cleaning Tabs

• Baking Soda - Mix 2 TBSP of baking soda per 2 liters of water. Add the mixture to your reservoir, shake it to mix the ingredients, let sit for 30 mins, then rinse/dry thoroughly.

• Soap & Hot Water

• Bleach - Fill your bladder with water, mix in 1 TBSP of bleach per 2L of water. Let sit for 30 mins, then rinse/dry thoroughly.

Drying & Storage

Whisk - Place a whisk inside the reservoir and lay it on it's side to dry.

Hanging - Hang the reservoirs over a shower rod overnight.

Freezer - Roll up your reservoir and store it in the freezer. Rinse with clean water before next use.

Can I order replacements? 

Of course! We sell individual reservoirs (clean and dirty in all capacities) as well as a replacement filter set here. 

Do you offer a warranty or money-back guarantee? 

Yes, we offer a 30-day money back guarantee, and a lifetime warranty on all of our products. Material or manufacturer defect? Our 100% lifetime warranty has your back. Lost or beat-up pieces? All Salado Outdoor components are sold separately for easy, affordable replacement. Don’t sweat it, we’ve got you.

What are the reservoirs made from? Are they BPA free?

The reservoirs and components are all BPA free.

Our reservoirs are made of FDA food grade Thermoplastic Polyurethane (TPU) material, which is BPA free, durable, lightweight, and can be stretched up to 750% it's original size. It was an obvious choice for us, and you'll find it to be dependable in the field for many years to come.  

The seals and welds in our reservoirs are made using a thermal binding process. The strength of the bonds can withstand up to 440lbs of pressure, all without using harmful chemicals or glue.

Does the filter need to be cleaned after use? 

We recommend back flushing your filter with a mild bleach solution after use. To back flush, fill a water bottle with clean water (use a 1 Liter SmartWater bottle, collapsible water bag, or any standard water bottle) and screw your filter's "out" side onto the bottle. Squeeze the entire liter of water through your filter. Then, squeeze 1 Liter of clean water through your filter. This process should keep your filter clean, and ready to use for many years to come!

Great Backpacking, Hikers Water Filtering System. Very light weight, less than 2 oz carry solution.

So far I'm very impressed with this setup. Bought the Salado Neptune Series kit on Amazon recently and tested it with our nasty lake water we have here at Indian Lake Ohio. Water filters through this filter system at about 1 liter per minute which is nice and comes crystal clear. Taste clean and refreshing, no remnants of nasty lake algae biomass smells. Love the pre-filter inserts which help reduce required back flushing large particles and helps keeping the filter overall clean. The 1 liter Tellus water bladder fold up bottles are great!
