Hi, does anyone know the difference (aside from the price) between the Sawyer Complete Water Purifier System and the Treatment System?

Not much to add to Greg's very complete answer... The main thing you need to know is: filter / treatment system (0.1 micron) = eliminates only bacteria, purifier (0.02 micron) = eliminates viruses as well as bacteria. Both are as good as it gets in their respective fields, so basically your intended application is what will determine your choice...

Besides the obvious size of the system 2 liter versus 4 liter. The biggest difference is that the Treatment system provides filtering protection for bacterial concerns in the water source, where the Purifier System filters out bacterial as well as viral concerns. This means that the filter opening size for the purifier is smaller and hence will take longer to filter the same amount of water. However, I did purchase the purifier system based on the area in which it was intended to be used. In other words, I went with the purifier system because of the concerns of potential Viral contamination in water sources being used to provide the clean water. The 4 liter system supported about 70 people after Super Typhoon Haiyan. I am sure, not its intended size to keep that many people hydrated, but it did and worked well according to my son who took it as a precaution, never hoping to have to use it. I hope this answer helps in your decisions making.

Water purifier filters particles down to .02 micron. The treatment system filters to .1 micron.

I was on my phone so it wasn't a long answer. I researched about all the shower filters on the market and I am an engineer so it was pretty detailed. I think the Envio is the best product n them market at this price point. It takes more media and more contact time to remove more chlorine. There are filters that have both but are much more expensive. Let me know if you want more information.

Thank you for your excellent question. As a starting point, I want to clarify that we use distillation as our core treatment technology because it consistently removes the largest range of contaminants, but we also incorporate other treatment methods into our water distillers. There is no treatment process that is perfect, distillation included. A good rule of thumb is that distillation is extremely effective in removing contaminants that have a higher boiling point than water, which is the vast majority of contaminants. There are some inorganic and organic chemicals that have a lower boiling point than water, such as chlorine. We handle this in two ways... First, our distillers incorporate twin volatile gas vents, a patented feature. These are two small holes that allow gases that are lighter than air, such as chlorine to harmlessly vent out. Second, all of our water distillers incorporate carbon filters, which are very effective at removing these gases that still happen to be present. Since we are running distilled water through the carbon filters we can make these filters last a very long time and we avoid the normal problems of carbon filters which include bacterial contamination. We have tested the effectiveness of our machines on chlorine with and without a carbon filter. Without a carbon filter we achieved a 93% to 95% removal rate of chlorine. With the carbon filter we achieved a 99% plus (which means that no chlorine was detected). Mike

I honestly do not know yet. Just bought it about 3 months ago. I use it daily. It does need distiller water. The add on filters did not stop the white dust. Using the filters and a pure water filtered water. Seems to be a lot better. I have had the same problem of replacing units every few months so we will see. Even with distiller water I had to replace them often. Sorry I can not be more helpful. It works great now but the future is well down the road.

I believe the difference is the level of filtration. I use the ez4 b/c It filters out more and smaller contaminant particles

About $200.00+. It filters 500 gallons per hour then the Classic. The only thing is that the Classic, and the Original, have a adjustable handle to direct the direction of the unit. I would call the Aquabot, and get there advise. My next Aquabot will be the Junior, and save between $150.00 and $350.00. Don't waist your time on the Turbo's. Too much $.

Alex,I installed the pre-filter. Unfortunately it didn't solve the problem and even with the pre-filter the main filters clogged up in about three weeks. I live in NYC and our water is consistently rated very highly. I've never heard that it is high in sediments. I was happy with the old filters for a few years and was on the Water for Life program. After my recent experiences I cancelled WFL and am searching for a non-Aquasana replacement system.

We, too, have a well. The Berkey web site should provide the info you're looking for (it is very helpful). Please be aware that it is a purification system as well as a filter.

I gave my unit with white filters away because I didn't trust it after my friend had her water tested and it came back unfit for human consumption. They refunded her money and sent her black filters but I never got the results after the filter change. My understanding is the white filters water and the black purify water. It was too late for me to exchange mine and the cost was not worth taking a chance on paying for replacements. Good luck.

I use this system at home, and a larger version (from a chemical supplier) in the laboratory that I manage. We routinely use the industrial version for a couple of years, because the water it is purifying has already been distilled, so the demand is low. There is no reason that the filters should not last for that time, assuming the useage is low enough. KLL

I would refer you to the Berkey website. They list all the types of things their filters can deal with. Not knowing what the specifics are, I would not be able to say. You could send them an email. I am sure they would respond. I do know that their filter systems are used worldwide for clean water in remote places.

i do not know what the difference is between the 2 cleaners. i would assume that they filters would probably be the same. you might try looking on their website (and then order from amazon) or call the company.

the difference that I see when you compare the two with their technical specs is that this system you don't have to change the filters for 12 monthsthe apex Water 50 GPD States 6 to 12 months and it also doesn't state anywhere that it removes 99 of the contaminants.and this system also comes with the water tester

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.

As I know it a RO filtration system will remove 96% of all contaminates. You probably have no better choice. We have 2 one at work and one at home and these are used exclusively for drinking water and ice maker water. They have both worked great and once you see what just the prefilter removes you will be amazed. I would highly recommend and RO system even if you think you have good water. Our employees haul water home.

I did not use the filters as we have a whole house system on our home as well and a reverse osmosis drinking water system. I only used the RO water in the fountian. My bulldog puppy has they unit chewed up with in a week :(

If you go to Sawyer's website you can see that they offer several units for in-home filtration, including pre-plumed kit with a backwash valve. According to Sawyer, they're designed for commercial and industrial use, but you can order it on their site for about $850. I'll attach the link.
