How long does each filter last?

Mine have lasted about seven weeks and we drink a lot of water. I refill the pitcher at least 3 times a day. So I feel seven weeks is a reasonable amount of time.

Our unfiltered water registers between 33 to 37. We were used to well water and don't like the taste of chlorine in our city water at our new location. Our filters last 3 to 5 months. We have had some issues with the reservoir draining properly. We just give the top a couple of taps and it seems to fix the problem. I think that the higher the register number on the unfiltered water the sooner the filter will need to be replaced to keep the 000 number. We think the replacement filters are a little pricey at about $15 each. Especially if they need to be replaced on a very frequent basis. Our investment on an annual basis is about $45 to $60.

Have had filter about a month. No problems thus far. Still on first filter.

I believe mine lasts about 2-3 months. I fill about a pitcher a day or so. I do notice some of the black bits ( charcoal?) floating on top of the filter before it goes through but that's all. My unfiltered water is in the 280 range.

Each lasts about 1 week. We are a family of three. So yeah they are pretty expensive

The filter lasts about a month for our family of two. However, it stops working prior to that time and we need to take it out and bang it on the sink several times to get it working again. When it actually stops working for good, the water gets a real foul odor and taste. We only put up with the inconvenience because when it works right it is far better water than we can get with any other filter.

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.

The filters usually last about one week. The last filters that I bought did not last two days. Lots of charcoal floating around when they were burped. I have never had to do this before. Not happy about this.

The filters last for 5-10 pots as long as the coffee is ground to drip-percolator size. Smaller ground becomes trapped in the filter.

There is no expiration date on the filters. With two people using the filtered water, mine typically lasts a year. The water flow will slowly decrease noticeably and after a couple weeks will actually stop so have another on hand when it begins to decrease.

Mine last about 3 months even though I used it a little longer until I ended up ordering a 3 pack. There's also a sensor that tells you when the filter is done.

They last a very long time! I use this purifier in my office that is in a warehouse which is very dusty and has a lot of traffic. I run once or twice times a week and over weekends. I went to change the filter for first time after nearly a year and filter was still pretty clean.

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

Hello Shelley, I often change the filters around 6 month and 1 year, this depends for the PH of water, I measure the PH if this drop down about 6, I change the filter.

I've had mine for two years & haven't replaced the filter yet. So, I don't know. It depends on how much you use it I guess.

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.

From amazon I think I've read 1 year, from another website that sells the same filter I've read 1-2 I guess it depends how much you use it. Hope this helps!

I replace mine every three of four months. Could go longer, but we have a central well in our neighborhood and often get sediment in the lines that has to be flushed out (causing my filter to clog). Generally, activated charcoal filters should last 4-5 months.

It depends on how hard your water is in your area. There are additives that you can buy that will keep the filter from becoming saturated with deposits, but I think most filters are good for two to three months of intermittent usage. Just check the filter to see if it is building up too much hard water deposits and not retaining its original flexibility and moisture wicking ability.

No. You can use between 1 and 3 filters. The more filters you have, the faster it will filter. 1 filter ~ 14 hours. 2 filters ~ 8 hours. 3 filters ~ 5 hours.

I got them here on amazon. You'd be surprised how long the filters last. I see 10 clue st a day on average and a filter will last me a out a month.

The filter comes with a small liquid type of timer with adhesive that attaches to the filter and you activate when installing it.Depending on the number of persons the filter may last 4 - 6 months. You will know when to change it by a noticeable drop in pressure.

It comes with one set of filters. The filters last between 6 and 12 months depending on how dirty the air is and how you clean them.

The unit figures that out for you depending upon how you use it and at what speed. My filters seem to last about 9 months or so.
