When you say 'life long' this means u don't have to buy another filter?

The manufacture recommends replacing the filter every 6 months period. Personally, I replace the filter every 3 to 4 months. For your information, most water filter manufacturers including 3M recommends replacing filter every 3 months.

The filter lasts about 4 months. This is much longer than previous filters I have used. Also, it depends on how much water you use. I make coffee with mine and use it for drinking water.

The unit figures that out for you depending upon how you use it and at what speed. My filters seem to last about 9 months or so.

Not sure why you are asking me how long this filter lasts. It was a disappointment from the beginning. I would not recommend it regardless of length of life

I don't think you need to buy a replacement filter. I keep vacuuming mine and it does great.

I've had mine for two years & haven't replaced the filter yet. So, I don't know. It depends on how much you use it I guess.

depends on how often you run it and how dirty your air is. Seems like mine lasted about 9 months being run daily. You just wash the pre filter

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.

I generally don't buy warranties. I've had this filter almost a year with no problems and same quiet operation.

The filters I had lasted three years. I had plastic melt on my stove and I used the fan to get rid of the smell. I'm sure that shortened the life of the filter. I had only used the fan less than once a week.

Yes, not sure how long the filter lasts but pretty much depends on the usage I guess.

if you keep the filters cleaned on a regular schedule they should last for many years. check your cleaning requirements (very simple and easy to do)

Could it be that it expires if you don't begin to use it for five years? The filters are fabulous, and will last up to 6 months if your water is normal. Ours is hard and full of rust, and it works for about 2 on average. Totally worth the 10 dollars.

Most of the filters say replace annually, bit it really depends upon your usage. I usually replace every other year and I haven't had issues with water quality...

Yes, there is another filter you can purchase for it. I did, and have not had to use it yet.

I think they say, with external vacuuming every month, it lasts up to 5 years. That was one of the reasons I ended up getting it. My experience was a little different, however: I cleaned it dutifully every month, and still needed to replace the filter after a little more than 3 years. The company, to their credit, did pro-rate the cost of the new filter for the time less than 5 years. Our home has two cats and we live in an urban environment where particulate matter counts might be higher than elsewhere. Your mileage may vary. Hope that helps.

Yes it is a long life filter, I use it along with extended mileage Mobile 1 synthetic oil. Very good oil filter.
