How do you know when to change the filters?

Filter life will vary based upon contaminant load and consumption. You'll know your filters need to be changed when: the sediment filter is getting plugged up when the water pressure drops, the iron filter when you start to have iron breakthrough, and the carbon filter when you change your iron filter. There is a filter life-cycle chart for the iron filter in your owner's manual and also on the product description page on the manufacturers website. Figure on an annual change in most applications.

The water pressure dropping is about the only way you would know unless you checked the filters. Which is why some people will install pressure gages before and after the filters. If the pressure gage after the filters is lower than the pressure gage before the filters, it's a good indication the filters need to be changed.

We change ours yearly (recommended for a household of 4), but really depends on water usage. I have been told, if your water pressure drops drastically, that is another sign that you need to change filters.

Usually every 6 months or so depending on usage. The machine will tell you when the filter needs changing

The instructions say change the filter every two months. I fill it with water every day generally.

We changed ours recently, but never really looked that close. The prefilter will be the dirtiest for sure, since air flows thru there first. The IQAir said it was time to change it so we did.

There is a push button below the left side of the read out labeled with the letter "F". Press that to reset the filter change indicator.

Change the pre filter as needed and every year change your carbon. Depending on how often you use your filter will determine how often you replace carbon. The best way to tell is the smell test. Simply get down by your filter and take a whiff. If odors are present, assure you have tight seals and are not over doing the cfm rating on your filter. If the answers are not the latter than replace carbon.

How often to change the filter is depended on the air quality in your house/room and how often the filter is on. You can tell by looking at the paper side of the filter. When the filter is getting "dark" grayish black color, the filter is near end of its life. Some people change filter every three, six, or nine months. That could be wasteful. I always inspect the filter and then change it as needed.

I would say it depends on the conditions at your home. We live up in the mountains where it is very dusty, so we check it at least once a month. We'll change it based on the amount of dust on the filter paper. We can generally go a couple of months before having to change it out.

The date you put in the filter so you know when to replace it. Like on a Brita filter.

Changing the filter depends on how often you use the coffee machine. We change ours about once every 18-24 months because we do not use the machine very much (about 2 - 3 times a month). You could also gauge the changing time by how the coffee tastes. If you make it the same every time and you notice it tastes a little different, you probably need to change the filter.

Hi. How old your filter? You have to change it ones per year.I did and I do not have any problem.

When I bought a new pitcher it showed a schedule of how often to change the filters, it shows every 2 months. I write it on my calendar so I don't forget.

I just put a piece of blue tape with the install date on the filter and replace in a year or if the flow slows appreciably (which in my usage/experience takes > 1 year). The filters have gotten more expensive - I used to get them for $70-80 so now I wait longer to replace :)

I changed mine at 3 months, mainly because I noticed by the contents of the bin that the airflow appeared to have decreased slightly. I used to change filters once a month before switching to the purple filters. I highly reccommend the -21 filter and brush upgrades.

Depends on how much the furnace runs, and the amount of particulates in the air. If you get one of these: G99 Air Filter Gage it will tell you when you should change the filter. When you're buying a filter this pricey, it will pay for itself.

Everpure recommends that the filter be changed once a year. To help you remember, they include a water filter monitor, which you activate upon installation. Basically, it's a countdown timer. When the time expires, an alarm will sound. Hope this helps.

I believe they suggest every 3-4 months...I purchased the filters online at amazon actually.
