How long do the filters usually last? At what kind of usage? Thanks.

Berkey says that the filters are good for about 6000 gallons (3000 per filter). The travel Berkey is 1.5 gallons so if you fill it once a day, that should give you 4000 days, or 10.96 years! We (2 of us) run about 10 gallons a week through ours when we travel for 5 months a year...a pot of coffee every day, drinking water, and a 5 gallon jug for the dogs. I'm told that when the filters start to filter very slowly, that is your clue that they need to be replaced. We had used ours for two years and they were working just fine (until I broke a filter and had to replace them). Depending on your usage, you should get several years out of these filters. Just a side note...if you break one they don't sell singles...you have to buy them in packs of 2 so don't leave your Berkey on the counter in your motorhome while you are traveling down the highway at 65 miles per hour (stupid me!)

I have had mine for 3 1/2 years and probably fill 2-4 gallons a day (my daughter fills gallons up to take with her, so I can't really say how much we have used). Over a year ago is when it slowed way down so that I had to take it apart and scrub it. That didn't help much, so I took it back apart and thought I'd try soaking it in vinegar, that didn't work, so I decided to scrape it with a knife and that helped, but I went researching how others clean theirs and came across a better way of what I basically had done. You can use a peeler and peel off layers. I have done that twice now, and figure that 3 1/2 years with all the use it has gotten is probably a pretty good time to get new ones.

Depending on how much water you use. Ours usually lasts about 2months.. Aside from that this is the best brand of filter we have used. All of the others Pur etc.. all start leaking and squiring water all over after awhile. I definitely like the Dupont filter the best.

The filters claim to be good for a year. I have had them installed for 9 months and my water still tastes great.

It depends on how much water you run through them and how clean the water is. For filtering tap water they should last for several years and the elements can be scrubbed if they get plugged up with sediment - i hope this helps

The filters last more long than, but i personally change it every time I notice the water pressure of the filtered water decreases which usually happens after 5-6 months but it also depends on how much water you drink a day

It was my understanding that the filters lasted the life of the machine. I clean it once a week with a vacuum cleaner...use the brush attachment.

It comes with 2 filters that last about 6 months. You have to replace them with new ones ...bought on Amazon. We still love ours almost a year later.

I am not sure exactly how long they last, however, we have used ours far longer than the projections and the filter worked great. Sorry i cannot be more exact. I just recently bought the first full filter set. It helps if you clean the outer filter often.

They may last up to like 3-6 months, just depends on how much you use the bottle. The filters can be bought right on amazon but I found then at Walmart to be a little cheaper.

Depends on how often you run the machine...I run mine about 12 hours per day and I change the filters about every 18 months.

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

We've used Pur filters for quite awhile and they always lasted me months. But this last batch of filters have had the same problem as everyone else here. The filters are lasting about two weeks. They never used to do that! I'm angry, too. These things are expensive and to replace them is going to be expensive.

Of course it ultimately depends on the environment you're in I've read that they last anywhere from 6 to 12 months, so far I have yet to change mine. I open it periodically to look at it and it is still pretty clean, the black pre-filter catches more and needs replacing more in my opinion. With four dogs I'm thinking of replacing the black filter soon on mine but it does come with extras when you buy it. It does have a filter light that will come on when the main filter needs to be changed as well.

Depends on how dusty the conditions are.It's best to clean them after each use.Order washable filters from Amazon and be done with it.

It depends on the quality of the water being filtered. If the water is murky, the filters will need to be cleaned more often and may last only one year. If the water is clear, the filters may last up to four years.

It depends on your use but I try to change once a year. I have gone much longer though and have not noticed any degradation in the taste of the water. The filters really make a difference.

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.
