how many months doest it work by one filter?

It really depends on how much you use it, it says about 16 gallons per filter, but I've found that it varies from time of the year (you drink more water in the summer), I'd say you would have to replace a filter at least once every 2 months.

I live alone and use about 2 gallons per week. My tap water varies from 175 - 225 tds. One filter lasts about two months -- but acting on another user's tip, I wait until the tap water has run for awhile for other purposes before filling my Zero pitcher. This seems to cut down on particles that accumulate while the water is sitting in the pipes, and consequently prolongs filter life.

It depends on the water you are starting with and how much water you go through. For example, my best friend and I both have one, but although we only live 20 minutes away from each other, our water tests totally differently on the dissolved solid test meter included. My tap water consistently measures about 385 tds, and hers tests about 480 (older part of town, older pipes, not sure, but consistent). My husband and I are both home all day, she and her husband work. I use it for filling our Keurig coffee maker in addition to normal drinking water. She and her husband work, don't drink coffee, etc. I change mine about once every 4-6 weeks, but find I change it more in summer when I am hotter, thirstier and drinking more liquids in general. She changes hers about once every 2-3 months. So there are a lot of variables. But, I can tell you that my trash recycling is down significantly that I am not buying all the little bottles and the taste is incredible. Far superior to Brita or any other filtered or bottled water you can buy. Fiji water tests about 120 by the way, and I only drink Fiji now as a last resort, i.e., can't get to my own. So for me, even if I had to change the filters more often, I would still stick with the system.

I have always used 2 filters at the time.For two people they usualy last about 70 gallons(36 cents/gallon). It depends on the reading you get on the tester from your tap water. Mine is about 240 ppm.I am thinking of purchasing right now a Berkey filter unit. They are a little more expensive but a set of 2 filters($107) works for about 600 gallons(18 cents/gallon). You also have an option for an extra set of filters to remove arsenic and fluoride. Check out their website at www.bigberkeywaterfilters.com.I hope this will help. Drinking clean water is very important.

Per ZeroWater's website: Though we are lab-certified for 22.5 gallons per filter under the strictest conditions, our customers with tap water near 200 TDS tell us that one filter will treat about 30 gallons of water before seeing a reading of 006 on their TDS meter. The lower the TDS, the longer the filters will last. You need to test your water to know for yourself.We are a household of 2 and our water tests at about 300 and we change the filter about every five weeks.

As Leaser states below, it depends on the quality of water you start with. I use mine at work, so I only run about a gallon a day through it, five days a week. The tap water measures about 180-200 ppm on the meter, and it lasts me about 2 months per filter, around 40-50 gallons, I would estimate.

It's not measured in time but more like usage. Our well water is around 120 TDS and we filter a lot for cooking, drinking and portable use in stainless bottles. Usually around 5 gallons a day. We usually change filters about every 3 months. Note our water is already very good so this isn't typical. We have a large 2 filter water cooler style housing. That's around 30 gallons per month per filter. Much better than the advertised 15 or 16 gallons.

My water source is ~296ppm. I get about 4-6 weeks use out of one filter before it gets an acrid taste that lets me know that the filter needs to be changed. My wife and I drink water about 90-95% of the time, so it gets a lot of use before I change the filter.

Where I live our water is nearly unfilterable due to iron lime and sulfur content out of the wells, but zero water makes it drinkable for 8-12 days per filter. Mind you its still cheaper and more convenient then buying bulk water to haul from walmart. (1 person 2 cat household for drinking and cooking water) pre filter concentrates test 900-1100, post, under 6 although ive found the water drinkable until it reads around a 12 before i can taste anything off again in mine.

The pre-filters seem to last about 4-6 months. We have dogs and that may affect filter life, although they may be on an automatic countdown timer.

Depending on the amount of use, your filters should last 3-6 months easily. You can greatly extend the life of the filter by using a small hand vacuum or dust blower to clean the filter regularly.

Every 3 months ....FYI: the filter is a bit smaller then what is listed so they may slide around but work fine.

There is no indicator on the filter. In the package with the filter it indicates 6 months of normal usage and then you reverse it in the case for 6 more months of normal usage. So one filter is good for 12 months according to the packaging. I would equate normal usage to 2 to 3 people taking a shower everyday. If you are a single person living alone, I would think a year between filter changes. For more clarity I would email the company, though.

Filter needs to be changed every 6 months or so - but realistically, I haven't done that yet and it seems to still work well. I run the machine on automatic every morning.

Hi, it says in the Ad that it can filter enough water to sustain a family of four up to a year. We have only had this about six months and the filter is doing great with no signs of slowing down. I can tell you that this does work great!

I haven't had any problems with mine since I put it in. Mine been in for at least four months now, my old filter in had to clean it every month and half.

Great filter! But the filter will last a lot longer than 2 months, try for four or when the stream starts to slow noticeably.

I change the membrane once a year and the filters every six months. Works well for me.

Me personally it is 4 to 6 months depending on how much the furnace or a/c runs and this winter it ran a lot. It's a good filter and I bought another one already.

i have gotten about 4 months out of 1 filter. i started noticing a difference in taste only recently.

depends on how often you run it and how dirty your air is. Seems like mine lasted about 9 months being run daily. You just wash the pre filter

I am pretty sure it is one year. This is my second one and I am quite happy with it. I broke the plastic connecting pipe to the filter unit when I moved. I've had the second one now going on two years. I've always kept it in my basement. I'm not sure how well it would do outside in a Michigan winter.

The filter lasted approx. 6 months. It would all depend on the quality of your water. This one was used in an apt. setting with city water, so I thought is was well worth the money.

There is one filter per order unless additional quantities of this filter are ordered at the same time. One filter should last approximately six months in "normal" usage. If you run the fan setting all the time , then this will affect the longevity of this filter.

Manufacturer says 1 yr. I doubt if we have to replace ours at 1 yr, just vacuum the pre filter monthly. That will make a big difference on how long the filter lasts.
