1. Your REFRIGERATORS should give you a signal like yellow then RED light that when you will need to replace it. 2. if your ice maker stop making ice, that the sign of replace the filter.

I bought a new machine because my filter finally wore out. By that time, the timer or sensor wasn't working exactly right anyway. They aren't that expensive to replace the whole thing.

The filter is showing signals that I will need to replace it soon. I bought it last June. The brush is fine because I remove any hair after each usage.

Not by visually inspecting the filter disc, its appearance doesn't change over time. There is a date wheel built into the top of the can, set it to the day of the month you first use it and change filter every 2 months on that day.

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:)

With this particular filter, we change it every three months, I hope this helps :)

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

Check to make sure it is going on the right rail. I had the same problem the first time I changed my filter.

I didn't use mine long enough to need a filter change. But from experience with other humidifiers, you should change the filter when it becomes discolored. The filter is you wick for moving the water to the top. When you notice a change in the amount of steam, the wick is no longer effective.

I generally change mine every 3-5 years, but it all depends on the level of pre-filtration, the level of chlorine passing through the membrane, the temperature of the water. I use a .5 or 1 Micron Carbon Block pre-filter and change it every 6 months. TFC Membranes have a very low tolerance for chlorine, so if you are not using a quality Carbon Block pre-filter, the membrane will not last as long.

What I did was vacuum the actual blue filter thoroughly as it really didn't look very dirty even though I got a "change filter" message. Then I washed the plastic grid piece it fits into thoroughly and let it dry. I reassembled it and still got a change filter message. However, I discovered there is a tiny "reset filter" hole near the top of the inside of the unit where you place the filter. I stuck a paperclip in the hole and pushed, and now it's behaving as if it has a brand new filter! I think maybe if this is done on a regular basis that you can get a lot more use out of this unit, even though the filters are "no longer available."

Sorry to hear about your trouble, try to run it on max without the ion function on for 15~20 min after you clean the filters. Good luck

There is a pre-filter that you have to change. There is an indicator to tell you when to change filters. How often depends on what setting you run. I run mine at medium 24/7, high for 1 hour after vacuuming. I change filters about every1 1/2 - 2 months. They're not expensive.

The pitcher can't "tell" when the filter is getting old. It's just a sensor in the lid that senses how many times it's been removed, etc. So it 'guesses' when its time to replace the filter. Holding down the button resets that counter to zero so do it when you put a new, fresh filter in and the light will give you an estimate on when to change the filter. I tend to use the filter at least a month after the light goes red.

I check the filter after the winter heating season and at the end of summer. Depending on use, I change filters once or twice a year.

There is a dial that slowly turns with each fill. After a while, it turns from green to yellow to red. When it's red, replace the filter and it rests back to green
