The "Electronic Filter Change Indicator" must run with a battery, how long can the battery last?

Sorry, I don't know. But I wouldn't recommend to buy this pitcher. No way to pour without excessive spilling. Although it looks pretty, the design is very poor. Save your money and your nerves.

and usage...if you run it 24/7. I would change every three or four months. Some folks just vacuum the filters. I'm goona try it.)

The filter lasts for at least 6 months. If you don't use it much then it can last more than 6 months.

Once the battery dies in the sensor, that particular sensor will no longer send a signal to the main alarm unit. I'm finding that the batteries are lasting about 6-8 months.

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.

Same here. You can remove the old battery and reinsert it to reset the internal counter. The battery should last for at least three cycles

Depending on the amount of use, your filters should last 3-6 months easily. You can greatly extend the life of the filter by using a small hand vacuum or dust blower to clean the filter regularly.

The sensor batteries last two years. The alarms run off 120v with minimal amperage. The alarm batteries will last one year or at least 30 minutes when running. That should be enough time to scare burglar without a UPS. Alarms are very loud.

I believe its a certain length of time. I marked the date on the timer when we installed it last time and it started beeping almost a year later. Also, the timer isn't attached to the filters. It's something that you and set/attach near by to remind you to change it.

I bought it in July 2014 and have not replaced the batteries yet. But I do not run it all the time just occasionally. I have a water barrel with few goldfish in it and just run it for about 30 min. at a time, maybe twice a week. Hope that helps some.

We have used this thermostat for over three years now, and I just had to replace the batteries for the first time about two months ago. I am not sure how long you have to change them out once the indicator light comes on, but we rarely look at our thermostat. So by the time I noticed our indicator light on, it had probably been on for a while. I can say that I have been quite pleased with this thermostat.

Yes, and you can program how many hours you want to run before the next filter change.

I can't tell you how long it lasts since I am still using it. Be sure and get the pre-filter which will keep most of the dirt off of this filter.

I have a indicator light on my unit, it lights up when needs to be cleaned, I say I replace the filter every 3 months

The sensor is battery operated, however the battery and all of the electronics are encapsulated and as such not serviceable nor replaceable. The battery does however last several years under normal conditions.

I don't remember since it's been so long since I bought it, but I've been buying replacement filters in bulk from Amazon at very reasonable prices. I noticed that a respondent said her indicator light stopped working. The light on mine stopped working but it turned out that I had installed a replacement filter backwards. I turned it around and the indicator light started working properly and has been working ever since with three subsequent filter replacements.
