How many gallons can it filter in its "life span"?

The lifespan of the straw is likely to depend on how heavily polluted the water is that you are trying to filter. http://www.lapolicegear.com/ndur-survival-straw.html This website states that depending on source water quality, it's roughly 25 gallons.

It says 25+ gallons depending on the water quality that you draw from(sediment,etc).

We recommend changing the filter every 6 to 8 months. However, the filter life will depend upon the environment in which it is used.

The filter is the only part to replace & that lasts for up to 300 gallons, of course if you are filtering really dirty water you would have to replace sooner.

The filter lasts for at least 6 months. If you don't use it much then it can last more than 6 months.

Yes, not sure how long the filter lasts but pretty much depends on the usage I guess.

Membrane every 2 years. Filters need to be changed more often--according to the amount of use.

We use this for a number of months. I would say 6 months. You could see on ours the filter looked dirty. We have real hard water. This is a factor. Just a guess once or twice a year.

The documentation says to change the multi-stage filter every 500 gallons, (every 6 months.) The ceramic dome filter at the top is supposed to last 1,000 gallons, (1 year.) I guess it depends on how fast you go through 500 gallons of water filtered.

According to the manufacturer it will filter approximately 300 gallons of water or 6 months. In my experience the water flow starts to slow down when the filter needs replacing. Another way to ensure that you replace it at the right time is to write the date of instillation on the filter with a black marker.

Hi Edward, I have the big filter series that take two filters. I use it for a fifty gallon rubbr stock tank I keep in the basement to keep giant goldfish brought in from the winter. I keeps the tank clean as there are 8 really big goldfish. I usually pull out the two filters about every three weeks or so. I also take out the whole unit and clean out the scum from the unit, So-- 3 into 52 weeks in a year-- 17 or 18 times. These are messy fish, so maybe I change them more often than I need. Hope that helps.

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.

This particular filter is 10,000 gallons but how do you know when you use 10,000 gallons, right? I use it mainly in my composting so I think it should last me quite a while. Also, if you get this one, and have to take it off your hose, lets say, to wash your car, keep the end with no filter pointing up as the charcoal will spill out. I hope at least some of this info is beneficial.

It depends on the quality of your water, but the documentation says it's good for about 25 gallons or so. You may notice decreased water flow through the straw or a change to the taste of the water when it's not really filtering well anymore. I love the fact that it has a flush capability so it will last better. Hope that helps!

I can't say how many gallons before its done but these filters with moderate usage last upto a year. I use mine for my koi pond and water for my dogs. I test the water often because I need to keep the chemicals out of my koi water and this is my second filter. The first one last one year give or take a month. I expect the second to last the same.

Officially, 40 gallons or every 2 months. However, I think you just need to be a bit creative when using it. First, you need to know the quality of your original water. If the original water is good, you may not need to change so fast. However, if the original water is bad, you may need to replace it faster. The filtered water do give better taste than the original water, so when you the taste of the filtered water turn bad, you may want to consider to change it even it has not reached the 40 gallons / 2 months mark.

When I bought the system it said on the box that for a family of 4 the filter should last about 1 year or something like that - now depending also of usage. I would at least change it once a year even twice in fact as I got more filters with my last order.

The filter is good for up to 200 gallons. The frequency in which you change your filter depends on your water usage. We change ours every 2 to 3 months.
