What is the longest time people have gone before changing the filter? I just changed mine after two years and it looked pristine.

I change it every year. You might want to check with Multipure to see if there are any negative outcomes with changing it that often.

We change ours annually. We drink lots of water, some coffee, tea, and fruit juice (from frozen concentrate), and absolutely NO sodas. In one year, we put a lot of mileage on our filter.

The filters are usually not white when I change them. But I change them about once a year, based on amount of use.

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'v had mine for a couple months now and have no need to change the filter, It's a metal type filter and completely washable, just rinse and re-use I use mine for loose leaf tea and works wonderful. Hope this helps

have you noticed any difference after cleaning the filter since it is not replaceable? did it damage it? that is a concern because i am definitely looking for a hepa air purifier with a pre-filter..

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.

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.

I've been using mine for 6 months and haven't washed the filter yet...oops. It hasn't seemed to need it though.

The best practice is to change it every 8 to 12 months. Even flowing strongly after that time filter could have lost part of its filtering properties.

Honestly it seems like every time you use it the filter gathers dust and you just wipe it off with your hand *Think lint brush here*. As soon as it's clean you're done. in terms of replacing it. Hmmm who knows...seems like it should hold up for quite a long time. If not you can replace it for like $5 on their website or make your own.

I have gotten away with not changing it for about two months. BUT that required me to keep the unit dust - free and clean on the inside as well s the outside. It also depends on how often you' re using it. If you use it constantly. then you will have to plan on changing the filter every month for sure.

It depends on your use but I try to change once a year. I have gone much longer though and have not noticed any degradation in the taste of the water. The filters really make a difference.

I clean off as much lint as possible and then wash it in the laundry tub (with a lint protector in the drain). I washed the original filter for almost 4 years and finally purchased the washable version. The original is still intact and can be used.

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."

I've owned a unit about two years. I replaced the filter after year 1 and just replaced it the second time. The unit seemed to work OK, but the filter does get a little "grungy". I'd say replace at least once a year (I only run the unit during the winter and early Spring months-November to April)

So far our filter has been holding up pretty good. I haven't had the chance to change it yet. Sorry.

I haven't had any problems with mine since I put it in. Mine been in for at least four months now, my old filter in had to clean it every month and half.
