How do you keep track of how much water you filtered? Or do you keep using it until you get sick and say, "guess I'll change the filter!"

I know the size of my water bottles and hydration pack combined by the number of mountain climbs it isn't hard to figure out. You could put a piece of tape on the side and make notes if you have trouble remembering.

Manual says after treating 750 liters or until it gets hard to pump/filter the water. This all depends on the source of water you are filtering and its quality. There are steps to keep the membrane fresh and disinfected as well as for long term storage when not in use.

I think it's supposed to be two months or 200 gallons, whichever comes first, the "whichever comes first" being the key statement. I change mine every two months, even though I know I don't use anywhere near the 200 gallons at that point. Less than $7 per month for filtered water is worth it to me. I think it needs to be changed that often as leaving it in longer may cause things to grow in it. I just don't take the chance and change it every two months, regardless of the fact that it probably hasn't had 50 gallons run through it at that point.

In their website they mention that the filter can last up to 3 months = 300 gallons. If I were you I would change the filter every 6 months just in case. And to be sure take daily measurements during one week to see how many gallons you need daily for drinking and cooking. That will give you a pretty good estimate on how much time the filter would last based on your needs.

We've had our filter for 10 weeks, still on same filter - and just tested it - oops, it needs changing. It measured 136, our tap water is cleaner at only 55, so it must start discharging the filtered "stuff" into the clean water, and starts to taste really bad, sort of metallic tasting.

[Sorry, I am having computer problems.] Re the filter. I guess it depends on the quality of your water. We are on a private well, and the water is very good. Our habit is to change the filters every 9 or 10 months. The plumber's rule of thumb at our house is to change things when the water starts to run slow - that could take a year. I'm too neurotic to wait that long! Lastly, there seems to be little water wasted in the process (maybe a small container's worth, about a quart). Best wishes, Lauren

I assume that the questioner wants to know if there is something that indicates when the filter needs to be changed. You should keep a spare filter cartridge on hand. Change it out when the water flow slows down. New, the flow will be about 1 oz. per second. An 8 oz. glass will be filled in 7 or 8 seconds. Over time, depending on the amount that you use the filter, the flow will slow to where it takes 10 or 12 seconds to filter 8 oz., it's time to replace the filter cartridge.

I find that changing that filter every 12 to 18 mos. is plenty to keep the water clean and fresh. As others have said, the company says annually, but they are making money more often that way. The filter I bought here is exactly the same except it has a lower price. What is not to love about that? (put masking tape on your filter and put the date your new one should be installed right on the filter casing.)

According to the manufactures info it is 6 months. We only just installed ours this month and really wont know until the water changes taste. In my experience with filters, most of the time you can get more filtered water than the manufacturer states but that depends on the area you live in (the chemicals in the water).

It really depends on your water. The higher the number from the wand (ppm) of your water the faster the filter will need to be changed. Our water unfiltered is about 34 and after 5 months we are on the same filter. We use at least two pitchers of water each day, usually more.

Hi Greg, That is a difficult question because it really depends on the quality of the water coming into the filter. The more "stuff" that needs to be filtered the quicker it will get used up. The best thing to do is to monitor the flow rate. When the flow begins to slow down noticeably it is time to change.

I change the water every week and rinse the filter. So once a month I change the filter unless it looks dirty before.

1. There is a little see-through sticker that comes with the pitcher, and a smaller marking sticker that you use to show when you put the new filter in, and the month that is two months later. For instance, I put the little marker over August - October. That will remind me that the two months is up. However, I live alone, so I figure my filter will last at least twice as long, so in October, I'll move the marker to October - December. I would use the 40 gallons, but that's just my opinion. 2. I'd have to think the shelf life of the unused filters is extremely long. I believe it's just charcoal inside a plastic casing, and I don't know why that would go bad. I ordered a pack of three spares, and I'm not worried about them going bad. I will probably take me at least a year to use them up. This water, cold, tastes delicious - the first water I've enjoyed drinking. (I'm not much of a water drinker, so having this pitcher has helped me drink more and keep hydrated much better than before I got it.)

I change it every 6-8 weeks and I buy them from Amazon. Since the water sits out for approximately a week (unlike our human water), it's a good idea to use the filters.

Trust me, change it every 30 days if you want the water to be fresh. If you forget to change it for 3 months, it will smell funny and won't be filtering properly. If you have ever noticed a water bowl getting a little slippery inside, think of what a filter after 90 days in water would be like. I got rid of my fresh flow because there were too many crevices that I couldn't get clean enough and it wasn't as fresh as changing out the water in a bowl everyday.

i use filter water from my fridge. and that helps.so right now I don't use the cleaning cartridge and clean the machine once a week.

The replacement period is primarily determined by usage and the number of gallons if water filtered. I would monitor your usage and change it as needed. Its just my wife and I and we used it for cooking and drinking and got a couple years out of ours.

Hi Bob: This totally depends on the quality of water in your area. If you are using frequently as you seem to, I would tend to be conservative and maybe change every 4 months. I change mine every six months or so but I use it along with spring water for actually drinking. My husband uses it for drinking and I use it for all cooking. It has definitely cut back on how much spring water we buy.
