How do you know when the filter needs to be changed?

These filters are good for a year or more. I reverse flush mine on the first of every month. The recommendation is every 2 months. You can test your water for chlorine just by buying some very cheap test strips from Lowes or Home Depot. Pool test kits work very well and cost around 20$. Amazon has litmus test strips very easy to use and cost around $8 for 25 tests. Using the reverse flush feature on these filters along with the test strips once a month or so, you can get up to 3 years usage out of one of these filters.

When the lights comes on to change it, you can simply clean out the filters yourself then reset the light. When the filters get too bad or if you don't want to deal with all that, you can change them but they are expensive. I change about 6-9 months or when the filter is really bad.

Clean the filter when you do a water change. Keep the water you got from the tank in a bucket. Clean the filter in that water

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.

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

I don't know. When the light went out I simply marked the calendar as to when to change the filter.

The directions for the platinum model say the filter should be changed every two to four weeks. It also says you can thoroughly rinse the filter and put it back in. I've had no problems with doing that.

Eventually the filter will need to be replaced. As long as you take care of it it last a long time.

This filter is intended to be changed every 12 to 24 months. It is recommended that the average household change it every 12 months for optimal performance and 18 months for optimal value.

The instructions state the filter should need to be changed every 6 Months. I bought mine in December 2012 and have not changed the filter yet. The unit has four lights that indicate when the filter needs to be changed. Mine is only on the second light indicator. I run the unit 24/7 on the second of four speeds, and wash the foam pre-filter every month.

I think that you will know EXACTLY when the filter needs changing! Your skin will feel itchy and dry. It will be a very definite change in your skin!! If you put in a new filter and your skin feels the same way, then take out the new filter and put the old one back in. It saves money if you test this way.

Just changed the filter a few times. Haven't tried to take apart and reassemble yet.

Have not detected a noticeable change in pressure but the filter needs to be changed periodically. My water is treated by our village and is hard. I change the filter every 6 months.

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."

not to my knowledge. I note when the container shows any orange around the lid - then I know that the filter needs changing.
