Typically How long do the filters last before having to be changed?

I bought a spare filter with it in December 2012 but have yet to use it. Note that I use the device daily n live in a especially polluted place.

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.

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

I have only had the unit for about 3 -4 weeks but there is a indicator on the unit that will tell you when to change filter. I do not know if this helps.

It depends on how much of the filter is covered. I change the filter before each time I use it.

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 depends on how often you run the unit and how much dust/allergens it's filtering out of the air. If it is always running then generally the filter should be replaced every 6-8 months.

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

When I bought the system it said on the box that for a family of 4 the filter should last about 1 year or something like that - now depending also of usage. I would at least change it once a year even twice in fact as I got more filters with my last order.

[Sorry, I am having computer problems.] Re the filter. I guess it depends on the quality of your water. We are on a private well, and the water is very good. Our habit is to change the filters every 9 or 10 months. The plumber's rule of thumb at our house is to change things when the water starts to run slow - that could take a year. I'm too neurotic to wait that long! Lastly, there seems to be little water wasted in the process (maybe a small container's worth, about a quart). Best wishes, Lauren

Very easy to change filters (hardest part is removing from water) - I rinsed filters out for about a year before replacing - how often depends on how much debris you have in your pond. Mine sits in deep shade and gets a lot of leaf debris; I changed out about 1 -2 x month. Warning: my pump stopped working after about 1 year and reviews are negative about the pump. Otherwise I was very happy with it while it worked.

The heating & air conditioning system I have recommends every 6 months. I know if you don't change them when the filter is dirty it will shorten the life of some components, particularly the fan motor due to the additional load caused by restricted air flow through the filter.

The filters are usually not white when I change them. But I change them about once a year, based on amount of use.

Generally, you should change your 1/2", 1" and 2" air filters every 30, 60, or 90 days; the 4", 5" and 6" air filters should be changed every 3 to 6 months, depending on your environment. Thanks, Jessica

I would think changing it would not be an issue for quite a while. I only use it once per month. The current filter should stay good for a long time at that usage rate. When the time comes, I will rinse the filter and put back in for as long as I can.

Personally I havnt had to change the filters as of yet and my machines run 24/7. I'm figuring every few months or so. The machines do come with replacement filters:)

It depends on how soon your scale build up on the filter. I change mine once a month from November to April.
