How often do you need to change the filter? I use mine up to 10 times a day, only using it while smoking and closing the lid right after.

Depends on how much you use it, once or twice a week for me before it quit working,,

None. You can use it for about a month. You move the filter ring around so when you know when to change it. But actually I never kept up with it and used it until I felt the filter needed changing again. I have changed coffee pots since I bought these filters but to answer you question the filters fit right in and work like a charm. You can see when the filter needs changing. I think a month and 1/2 and then a change. If I was still using the same coffee maker I would have kept buying these filters. too easy not to. Enjoy your coffee

The regular filter only has to be vacuumed, not replaced. They do recommend replacing the thin charcoal filter periodically. However, since we do not have a smoker of pet in our house, I have not plans to replace it. will just vacuum dust from it every month or so.

That's hard to answer. It really depends on how dirty or clean your air is. The system tells you when it needs to be changed. I actually clean the charcoal filter several times before changing it. The other filters I only change once a year. I hope that helps. :)

I replace the filter about every 9-10 months. It runs 24/7 on fan speed -2 except for those weeks when the weather is nice and we open the house. I wash the foam pre- filter every month

I just purchased this item so don't know how long it will last. The instruction manual states the filter should last 6 to 9 months. I would guess that depends on usage. I use mine about 2 to 3 times a week and for a short period of time.

I have used this filter the same way for about a year now. Single person use, drink a gallon daily, use it for cooking. I replace every 5 months.

Hi there, according to my family usage (we have 11 people in our home) filling the berkey 1-2 times per day we would expect to change the filters every 3 1/2 -6 years. I looked around on the web a bit and found the same to be true for others. We have had ours for approx. 2 years now and it's still going strong and tasting great. We did put a pur filter on our kitchen sink for filling pots for soup etc. We use the berkey for everyday drinking and for filling the teapot :) - Annalisa

There are three filters One permanent, two replaceable. You should "clean" and re-use the initial filter monthly depending on the work load. I haven't had this unit very long so I just take the front cover off and visually check the filter. The cover is very easy to remove & replace. The other two filters are expected to last around 18 months. They have to be replaced, not cleaned. When the cover is off there are a series of led lights telling you the condition of the filters. By the way, removal and replacement of the filters is really easy.

Every 6. month's but make sure it's the correct filter because the one I. ppurchased in December was shipped with the wrong filter it blew dust out. replaced with right filter this is my second one. That's why I purchased this one, the last one lasted fir 10 years. It ran 24 hours 7days a week nonstop.

I haven't yet had to replace the filter. I don't use it that much. My filter is a permanent filter and I just empty it in the trash when I use it.

The purifier reminds you to clean (vacuum) the filters every month or so, and they can also be gently sprayed through with a hose. You can order replacement filters from <https://www.envionproducts.com/air-purifiers/replacement-parts>, but I have only replaced the filters after 1.5 - 2 years (2 smokers in the house).

Approx. every six to eight months, running it 8 hours a day in my bedroom. I live in the southwest, in a dry dusty environment, so it would probably last longer under less severe conditions. Also, I must clean the pre-filter at least once a week.

Eventually the filter will need to be replaced. The replacement Frequency depends on usage. In my case, usage is moderate, less than 12 hours per week, so I expect the filter will last several years. The "cleaner" mechanism works very well to remove the more coarse grain dust, but the very fine dust will get trapped in the filter and build up over time. I am very pleased with the performance of this unit. I added a third party remote to complete the configuration.

Filter needs to be changed every 6 months or so - but realistically, I haven't done that yet and it seems to still work well. I run the machine on automatic every morning.

depending on what you are using it for. I know smokers have to change it twice a year. Once a year is what I do.
