HOLLOW-FIBER WATER FILTRATION
Sawyer Products was founded in 1984 in Safety Harbor, Florida. It started with a snake venom extraction kit and a chemical-protection line for serious outdoor use. A chance encounter brought them to hollow-fiber membrane filtration originally developed for kidney dialysis, and the rest of the company's mission rewrote itself. Today their 0.1-micron filters are rated for up to 100,000 gallons each, and through the Sawyer Foundation and 140+ charity partners across 80 countries, Sawyer reports more than 25 million lives served clean water.
Sawyer rates the 0.1 micron absolute hollow-fiber membrane to remove 99.99999% of bacteria (such as salmonella, cholera and E. coli), 99.9999% of protozoa (such as giardia and cryptosporidium) and 100% of microplastics. Sawyer's published ratings do not list viruses or chemical contaminants.
Sawyer rates the filter for up to 100,000 gallons. When the flow slows down, backwash it with the included cleaning plunger to restore it.
Sawyer states that the CNOC TPU bladder is BPA free and FDA approved.
Most in-stock orders are processed within 1 to 3 business days, not counting weekends and federal holidays. Special-order, dealer-direct, custom, and LYNX Survival Systems orders can take longer. Lead times shown on product pages are estimates, not guarantees.
Typical carrier transit after that: Economy 5 to 7 business days, Expedited 2 to 3, Overnight 1. These are carrier estimates, not guarantees. Some items, such as lithium batteries, aerosols, and safety matches, may be limited to ground shipping.
Free Economy shipping on qualifying orders over $150 to the contiguous US, on eligible products. Oversized, heavy, freight, hazardous-material, dealer-direct, custom-built, and special-order items may be excluded. Oversized and freight items, such as rooftop tents, recovery equipment, and Pro Eagle products, may carry extra shipping charges. If extra charges apply, we'll let you know before the order ships.
Some items ship directly from the manufacturer or a supplier partner on their own schedule, so an order can arrive in more than one package with more than one tracking number. Full details: Shipping Policy.
You have 30 days from receiving your order to request a return on eligible items. Email info@stayreadyoutdoors.com with your order number, the item, and the reason, and wait for return authorization before you ship anything back. Returns sent without authorization may be refused.
Items must come back in like-new condition: unused, unmodified, unworn, unwashed, and free of odors, dirt, stains, pet hair, and damage, with all original packaging, manuals, accessories, and tags, plus proof of purchase.
For standard parcel items, you pay return shipping unless the return is due to our error, shipping damage, or a verified defect. If we provide a prepaid label, its cost may be deducted from your refund. For oversized, freight, dealer-direct, and special-order items, you pay return shipping unless the item arrived damaged, defective, or incorrect. Original shipping charges aren't refunded. Some items may carry a restocking fee of up to 15%, and we'll tell you during authorization.
Some items are fulfilled by third-party suppliers and follow that supplier's return policy, so eligibility, refund timing, return shipping, and restocking fees may differ.
Approved refunds go to your original payment method. Allow up to 10 business days after approval, and your bank may take longer to post it. Full details: Return & Refund Policy.
These can't be returned or refunded, except where the law requires it:
For built-to-order, custom, and special-order items, exceptions may be made only for verified manufacturing defects, shipping damage, or fulfillment errors. For food and drink, replacements may be issued only for verified manufacturing defects or shipping damage reported within 5 days of delivery, with photos.

You don't pay return shipping on items that arrived damaged or wrong, or with a verified defect. Some items fulfilled by third-party suppliers follow that supplier's policy instead. Reporting after 7 days may limit our ability to pursue a claim with the carrier, and while we may help with a carrier claim, approval is up to the carrier.
