Approximately how long do the replaceable filters last? Realize this depends on the level of air contaminants, but want to get a rough idea.

They last a very long time! I use this purifier in my office that is in a warehouse which is very dusty and has a lot of traffic. I run once or twice times a week and over weekends. I went to change the filter for first time after nearly a year and filter was still pretty clean.

There are two filter that the tower uses. The first, is the Air Purifier Booster Filter and then there is the Hepa Filter. I've had mine for about 2 years and run it everynight, and so far, have only replaced the Hepa Filter only once. The Booster Filter does NOT need to be replaced! Yes, you heard it right! I Vacuum mine and good as new. Some previous post wrote that they washed it. I think that is a waist of time and too much mess. Get a good vacuum and hose it down. Hope this helps.

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.)

I think is based on time. The filters continue to work for some time after. I generally replace them whan the water flow slows down. depending on use, that can be 1 to 3 years.

They may last up to like 3-6 months, just depends on how much you use the bottle. The filters can be bought right on amazon but I found then at Walmart to be a little cheaper.

I believe they're only supposed to last 6 months. Our initial filter lasted that long.

They also sell those filters right here on Amazon. Just look up filter H, i believe thats the code abbreviation for this particular model. Theyre around 8 bucks, but I hear they last long!

According to the instructions, they will last 30-40 fillings of the tank. In my case it is about every 3 months which is similar to the older filters.

My HEPA filter is about half used in 14 months. I replaced the fairly inexpensive carbon pre-filter once at 13 months. This product works well, and I don't mind the cost of the filters. The unit has two indicators that tell you when to change each of the filters.Bruce in Texas, retired engineer

No real experience with this model. With other types it all depends on how long you run it and how dirty the air is. I have had hepa filters go from three months to a year. Vacuuming the hepa also helps.

We've had ours for about a year. No issues yet, just need to change the filter.

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 believe mine lasts about 2-3 months. I fill about a pitcher a day or so. I do notice some of the black bits ( charcoal?) floating on top of the filter before it goes through but that's all. My unfiltered water is in the 280 range.

It often depends on how clean your filters are. Our water has a lot of minerals in it. I change my filters every 3 weeks. A full tank with clean filters lasts about 12 hours. With dirty filters, the tank never empties properly. The water can't get through the clogged filters. I always run my humidifier on high, and I keep my humidifier clean. Breathing for me is always easier with properly humidified air.

It was my understanding that the filters lasted the life of the machine. I clean it once a week with a vacuum cleaner...use the brush attachment.

I don't have the product literature in front of me, but usually these things can go 3 months or so before the filter is changed out, especially if the water is kept clean. Filter longevity will depend on your water and how much stuff the pets might drag into it.

I am not sure how long I have had mine, but never replaced filters in the past. I wash them after each use. I purchased this one because I changed coffee makers.

What is your question? I can't understand why these filters would expire after two or three years if you have not installed them.Perhaps the expiration applies if they've been installed and water has run through them. If you install and let them sit there for three years I can then understand having to change them after two/three year; even if they just sat there unused.

From amazon I think I've read 1 year, from another website that sells the same filter I've read 1-2 I guess it depends how much you use it. Hope this helps!
