Sawyer says this system will filter 170 gallons a day, yet one of these reviews says 1 liter per hour and Sawyer agreed. So which answer is right?

The one liter per hour is not correct, either the bucket was not high enough or there was an obstruction with the line to the filter. I don't know why it would be listed as "1 liter an hour" You can practically put your mouth on the filtered end and suck up water with hardly any effort.

I imagine the 170 gallons a day is either in a squeeze bag, connected to a tote, or something of that nature. 1-2 liters per hour sounds pretty realistic given the pore size on the filter, and what it is designed to be. As with any survival item, never wait till you have to use it to test it. Leaving something in the wrapper that your life may depend on to keep it shiny is a sure fire way to get you killed.

This video states that it can filter up to 5 gallons an hour. If you are getting performance less than that, you either need to prime the filter before using it OR back flush it to make sure it's clean after extensive use. I'm sure that height of the gray water bucket makes a difference too. Here is the video: https://www.youtube.com/watch?v=sjIVoaIdsss

For marketing outside the USA, Sawyer uses Liters, for inside they use Gallons. It will do both and almost no one has tested the 170 gal. limit.

The first time that I used the Sawyer, I tested it out using gravity feed from countertop height to a bucket on the floor. I was able to filter four gallons overnight. I have a Katadyn Gravidyn three candle filter that I use daily. The Sawyer will only serve as a backup.

I filter 2 to 3 gallons of water per day. A filter lasts me about 3 months, maybe a little longer. There is a little bit of black bits that float on the water before it goes down through but that's not a problem. I haven't had all those problems that others are talking about.

Gallons per day as others have stated but they both fit in the chamber so either will actually work. The 18 is much slimmer so even if you don't need 18 gallons per day the 24 is likely to last quie a bit longer and therefore justify the extra cost. Again, they will both fit if you have chosen the actual model number for your unit. Hope that helps?!

That is exactly the size pool I purchased this filtration system for and it works great. I would recommend it. I run it for about 4-5 hours per day and it keeps the water crystal clear.

My pool is 18,000 gallons and this filter is at least one size larger than I needed...however I feel strongly that a filter system should have excess capacity- and the price difference was minimal so I deliberately purchased an oversize unit. I have been extremely happy with it. It keeps the water crystal-clear and requires almost no maintenance. (Just lubricate the o-rings periodically with a high quality lubricant) Keep a spare filter so you can just swap the extra one in while you clean the filter. My previous Hayward system was smaller - and lasted over 14 years. Hope that helps....

Only thing I can find is on the sawyer website is the lifetime warranty so if you read it the will fix/replace the filter for life as long as you dont modify the filter in anyway or open the housing or run juice or drink mixes thru it they will replace it the 100,000 gallon guarantee is to tell you you will have it for life you will lose it beforeit breaks I hope I was of help you can find all the tech data sheets on there website

It is rated for up to 160 gallon, but in actual use I would say probably a 90 gallon. It has a flow rating of 330 gallons per hour but that is with no media so in actual use the flow would be less. It really depends on how many fish and type of fish you are going to keep. I have this filter on a 90 gallon and keep African Cichlids. Normal wisdon says you need to cycle the tank 8 to 10 times per hour. So I run this filter and a 460 Fluval. You will have to decide how many times per hour you want to cycle your tank and how many inches of adult fish you will eventually have?

I can't speak for everyone but mine takes about an hour to filter 1 gallon of water. And I use my hose because the filters won't allow much water through and it backed up my plumbing and leaked under my sink. I stopped using it all together

The upper portion uses 4 filters all at once. The Berkey web site states that the filter lifetime is 3,000 gallons per filter.

I don't know actually, i was looking at gallons per hour rather than pressure when I bought it. Having said that, I have no way of telling if it meets that spec or not, but it seems to be working.

It depends on where you live and how humid it is and how much you run the unit. If just a little water is collecting each day, I would think once a week would be enough. Do check it regularly..you do not want it to overflow.

The label on the pump says 240 liters per hour as the stated maximum flow rate. When you do the math, that means 4 liters per minute. I'm not sure where the ad gets 3.6 from.

Depends on your ppm water content, my post whole house water filtration system has 50 to 65 ppm (parts per million) any given day. One AP430SS is plenty for my tankless water heater. I do not know how long it is going to last yet. But, so far so good. James

I'm having no issues with the filtering speed. It may slow down with time but a fresh one filters a cup's-worth of water in no time.

Depends on how much water goes through them. I fill the reservoir 2-3 times a day (about a liter fits in the reservoir). I change my filter about 2-3 times a year.

Dear Valued Customer, Sawyer states, "The Sawyer Water Filters feature a 0.1 Micron Absolute Hollow Fiber Membrane, which uses medical technology developed from kidney dialysis. When the water is drawn through the filter, it flows through the side walls of the Hollow Fiber tubes. Sediment, bacteria, protozoa, cysts, and other contaminants are filtered out exceeding all applicable EPA recommendations. NO CHEMICALS, NO WAITING, NO PUMPING, NO WORRIES!" We hope that this sufficiently answers your question. Please let us know if you have any additional questions. Thank you for your inquiry. Sincerely, Thunder Mountain (ThndrMntn) Sales and Service

It depends on which size container you have. We have the Burkey Traveler which is a little over a gallon and it only uses one filter at a time, but some of the larger containers use two at a time.
