how long does one filter last?

Wrong question. It's not like a pair of shoes where you can see wear after a given time. It's about your health and the instructions that came with the unit are to be followed. Read them, I'm not going to reprint them here for lazy people.

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 the water is. I have a water softener and the water saturation screen (not really a filter) lasts several years. Untreated water in areas with very hard water could reduce the time to six months, I imagine.

Filters last about 10 uses but if you rinse them out really good you can probably get a few more uses out if them. Once they start to clog up with sediment you will know because the coffee concentrate will not flow freely through it.

Depends on your usage, how hard your water is and how often you clean it. If you maintain properly, it should last 3 to 6 months. Google how to clean a humidifier filter. Cleaning it is the key to its longevity.

"dispose of filter after 40 hours of use or 30 days, whichever is first" - http://multimedia.3m.com/mws/mediawebserver?6666660Zjcf6lVs6EVs6662M_COrrrrQ-&WT.m;c_id=www.3m.com/filterchange

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

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.

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.

I use this system at home, and a larger version (from a chemical supplier) in the laboratory that I manage. We routinely use the industrial version for a couple of years, because the water it is purifying has already been distilled, so the demand is low. There is no reason that the filters should not last for that time, assuming the useage is low enough. KLL

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.

I find one site that sells cartridges (houzz.com) says "Each filter cartridge should be replaced within 45 to 60 days depending on usage. Today I talked to the UnitedStatesian distributor (not the Amazon distributor in Canada), and he says it's good for roughly 6-8 months showering 2 times a day.

Naturally, it depends on how much you use it, but we get at least a month or two out of each filter. We can tell by the taste when it needs to be changed.

Hello, C.J.E! With average indoor air quality and 24 hour daily use, the filters in the BioGS 2.0 will last for 18 months. If you have any other questions please feel free to let us know! Regards, The Rabbit Air Team

I believe the filters last through at least 30 gallons of water or 3-4 months.

I change them a little longer that the recommended times. We use the filtered water only for cooking and related things. There are two time frames: One filter will last one year plus and the other two should be changed every 6 months. As I said we try to wait a little longer. Maybe 8 months for the two and 14- to 16 months on the one. It really depends on use and the quality of your water.

Every 6. month's but make sure it's the correct filter because the one I. ppurchased in December was shipped with the wrong filter it blew dust out. replaced with right filter this is my second one. That's why I purchased this one, the last one lasted fir 10 years. It ran 24 hours 7days a week nonstop.
