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.

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.

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.

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

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.

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.

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.

I am cleaning the fountain once a month & do replace the filters. They say they last 2-4 weeks. I have 3 small dogs & 2 cats using the fountain if this helps. They love it!

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!

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.

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.

If you are getting the filters with the purchase of the unit, about 40 or so I think. (Enough to last about a year for me, and I use multiple pads each time I use the unit). If you are getting the refill pack, I'd say about 40 or so again. Hope that helps!

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

I believe one should last about 6 months, but I don't have any pets. What I usually do is run the filter under some water and give it a good clean and its like new.

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.

Ditto Donna BUT I saw on their web site that you can vacuum the filter (usually 12 months from the time you started using it) and that the filter should last a total of about 2 years. Now we know why it was a Gold Box Deal when we bought them!

Depends how much water you drink. I guesstimate 2 months. You can get filters on Amazon or Ebay.
