Our testing and transparency is unparalleled, as is our commitment to social impact and environmental sustainability. WHAT SETS LIFESTRAW APART 1. Tough and Minimalist: Our products are made with minimal spare parts and are used in the toughest conditions around the world. 2. 3. LifeStraw is the only water filter brand that owns and operates its own fully equipped ISO certified water laboratory 4-step quality control including microbiological testing over every single batch of filters. 4. We give back: We provide a year of safe water to a child in need for every LifeStraw product sold. 5. Transparent testing: We share all internal and external lab reports publicly, on our website. 6. Optimal flow rates: Optimized to operate off of human sucking & last longer in sandy & silty conditions. 7. Sustainable packaging: All packaging is free of plastic and is fully recyclable or compostable 8. It's all about the 9s: We report log removal (99.999999%) data for all of our microbiological claims. 3 HOW WE TEST OUR PRODUCTS LifeStraw's testing and transparency is unparalleled and we use the most trusted performance criteria based on protocols established by the World Health Organization, the US EPA, NSF International and the Water Quality Association. ALL LIFESTRAW PRODUCTS REMOVE: · LOG 8 (99.999999%) for Bacteria · LOG 5 (99.999%) for parasites/amoebas/cysts · LOG 5 (99.999%) for microplastics · BPA FREE · FDA Food Grade Materials 4 STEP QUALITY CONTROL LifeStraw is the only water filter brand that owns and operates its own fully equipped ISO certified water laboratory capable of performing cutting age tests on microbiological performance longevity, turbidity and other performance indicators. LifeStraw also tests all products through external internationally recognized labs. LifeStraw puts 100% of its filters through a rigorous quality control process. STEP 1: Resistance test at high pressure. STEP 2: Bubble test to confirm pore size. STEP 3: Particle test to ensure nothing the size of bacteria or larger can pass through the filters. STEP 4: We send a sample from every batch for full Bacteria and Protozoa log removal tests. MICROBIOLOGICAL TESTING HOW ITS DONE The only accepted scientific evaluation of microbiological filtration performance is log values (the number of 9s in 99.999999%). PERIOD. All internationally accepted protocols from ANSI, WQA, NSF International, the US EPA, and the World Health Organization evaluate performance through log removal testing. None of these bodies will certify anyone based on pore size; it is ACTUAL PERFORMANCE that matters. LifeStraw products exceed all log-based performance standards. 4 PEAK GRAVITY WATER PURIFIER PERFORMANCE DATA IN D E PE N D E N T LY T EST ED LifeStraw water purifiers are rigorously tested by independent labs and our own ISO certified lab to meet protocols established by the US Environmental Protection Agency (EPA) and NSF International/ANSI. · Membrane Ultrafilter pore size - 0.02 micron · Meets NSF/ANSI P231 standard for reduction of viruses, bacteria, and parasites M E M BRA N E U LTRA F ILT E R LASTS UP TO 18,000 L REMOVES 99.99% OF VIRUSES Adenoviridae Astroviridae Calicivirus Enterovirus Hepatovirus A (Hepatitis A) Influenzavirus Norovirus Human parainfluenza viruses (HPIVs) Paramyxovirus Human parvovirus B19 Rhinovirus Rotavirus Alphavirus Rubivirus (Rubella) REMOVES 99.999% OF PARASITES Ascaris lumbricoides Cryptosporidium spp. Entamoeba histolytica Giardia intestinalis (Beaver Fever) Taenia saginata Naegleria gruberi Schistosoma mansoni REMOVES 99.999999% OF BACTERIA Brucella melitensis Campylobacter jejuni Francisella tularensis Pseudomonas aeruginosa Shigella Staphylococcus aureus Vibrio cholerae (Cholera) Vibrio parahaemolyticus Yersinia enterocolitica Yersinia pestis Enteropathogenic Escherichia coli (E. coli) Haemophilus influenzae Klebsiella pneumoniae Legionella pneumophila Mycobacterium tuberculosis Mycoplasma pneumoniae Burkholderia pseudomallei Salmonella enterica Salmonella typhi (Typhoid) Streptococcus pneumoniae Streptococcus pyogenes Leptospira REMOVES 99.999% OF MICROPLASTICS RE D UC ES T U R B I DI T Y (SI LT, SAN D, CLO UD INESS) The above is not an exhaustive list of all bacteria, parasites, and other contaminants removed by LifeStraw filters but rather the main waterborne disease-causing contaminants.

In this study, the longevity (filtration lifetime) of LS Peak Gravity Purifier was evaluated, and microbiological removal efficacy was tested along the longevity test. The filtration lifetime of product was tested following US EPA (1) and NSF P231 (2) protocols. All tested samples have been tested till 6000L under NSF P231 test conditions then extrapolation analysis was applied to estimate the full lifetime of the product. During the test, the flowrate of the samples was about 450ml/min (27L/h) at the beginning, then decreased slowly over the filtrated volume and maintained stable at around 200-250ml/min (12-15L/h) since 3000L. All tested samples could remove bacteria at higher than 8log reduction and remove virus at higher than 5log reduction during the test. The turbidity of filtrated water was lower than 0.5NTU at all sampling points of all tested samples, and it was 0.1 NTU in average. The quality of the filtered water exceeded requirements of US EPA/NSF P231 on bacteria removal (log6), virus removal (log4), and turbidity removal (0.5 NTU). Extrapolation analysis showed that the samples can exceed 18000L (target lifetime) without any possible clog before 14000L. From 14000L the flow rate might fall below 100ml/min and need to apply the available unclogging step to maintain higher flow rate till end of lifetime of 18000L. 10 LONGEVITY TEST GRAVITY WATER PURIFIER Water Laboratory LSF.22.1001.4 Longevity of LS Peak Gravity Purifier _ Report References 1) US EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers, April 1987. 2) NSF Protocol P231, Microbiological Water Purifiers, 2014. 3) WHO (2011), Evaluating household water treatment options: Health-based targets and microbiological performance standards, Geneva, World Health Organization. 4) NSF/ANSI 53, Drinking water treatment units health effects, 2021. 5) WL.SOP.062 - SOP Validation LifeStraw Peak Gravity Purifier. Procedure/ Testing methods Following US EPA/ NSF P231 protocols, 5 replicates of LS Peak Gravity Purifier were aged with general test. At the beginning and after each 1000L of longevity, samples were tested with challenge test water to evaluate the microbial removal efficacy (E.coli, MS2 virus and protozoa) of the product. Operating the product during testing was done following WL.SOP.062 (5). Testing water conditions were prepared and controlled following US EPA (1), NSF P231 (2). Monthly cleaning was applied for all tested samples for every 300L point, following WL.SOP.062 (5). Results and discussions 1.

Then flowrate decreased slowly over the filtrated volume and maintained stable at around 200-250ml/min (12-15L/h) since 3000L. Page 2 of 4 11 LONGEVITY TEST GRAVITY WATER PURIFIER Water Laboratory LSF.22.1001.4 Longevity of LS Peak Gravity Purifier _ Report - Extrapolation analysis showed that the samples can exceed 18000L (target lifetime) without any possible clog before 14000L. From 14000L the flow rate might fall below 100ml/min and need to apply the available unclogging step to maintain higher flow rate till end of lifetime of 18000L. - Turbidity of effluent water was about 0.1 NTU in average, and lower than 0.5NTU at all sampling points of all tested samples (table 1). This result met NSF 53 (4) and USEPA (1) requirements on turbidity of effluent water.

Microbial removal efficacy - LS Peak Gravity Purifier uses ultra filtration (UF) membrane technology which can remove microorganisms bigger than its pore size of 20nm (0.02µm), thus, it can remove E.coli bacteria (ca. 0.5x2µm), protozoa cysts (minimum 3µm), and virus (MS2 coliphage ca. 23-28nm). - The removal of protozoa will be tested at end of lifetime (as 3 micron microspheres surrogate). Removal of E.coli (the smaller tested organisms) guaranteed removal of protozoa. - The results showed that, throughout the test , microorganism removal efficacy of all LS Peak Gravity Purifier samples was higher than 8.2 log reduction of E.coli, and 5.2 log reduction of MS2 virus. - LS Peak Gravity Purifier exceeded the requirements of US EPA (1)/ NSF P231 (2) on bacteria removal (log6), virus removal (log4) (table 2).
