How long does this filter work for before needing replacement?

It all depends on how dusty/dirty of an environment you're working in. A dirtier job like auto body or drywall sanding will provide a shorter life cycle for this filter. Determining whether the filter needs replacing is a subjective thing based on observation and how contaminated the filter has become with the job task.

Haven't changed mine yet but not doing a lot of carving. Someone else might have a better answer.

I think manufacturer recommends every 2-5 years for membrane (we can usually tell because the water flow decreases), other filters are every 6 months. Check out this link: http://www.premierh2o.com/filter-replacement-guide

Actually yes. You'll know when it needs to be replaced because the flow of the water will decrease. In general the manufactor recommends replacing it every 6 months with your average 10,000 gallon usage. Main reason I purchased this filter was for the chlorine smell reduction and it does a pretty good job at that. Having said that, I will more than likely replace it every 4 months because the Chlorine really get's to me while showering and it's a great neutralizer for that. I hope this helps.

The company that installed my new system said that this filter would last one year. But when they came out to do an inspection after one year, the guy said that I should have changed the filter earlier. I now change the filter every six months. So far, that seems to be about the right amount of time.

I have washed it a few times but I finally bought a replacement because I wasn't sure how well it worked after washing it 10 or so times. But it seemed to worked even after washing it, so you can probably get away with using the same filter for a year or two.

Directions say one filter is rel\placed at 6 months and second is replaced at one year. Sorry, I do not remember which gets replaced at which time frame.

Clean pre-filter 2-4 weeks, deodorization filter replace 6 months, HEPA filter replace every year.

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)

Craig, It is difficult to put a number on how many gallons of water a filter will sufficiently filter before needing to be replaced. Even among city water systems there are varying amounts and types of chemicals that need to be filtered out. We say that it will last a typical camping season or three months of normal use before needing to be replaced. However the key is to keep an eye on the flow rate and taste. Once the flow begins to slow down or you notice a chemical taste in the water that wasn't there previously then you know it is time to replace the filter.

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

We recommend changing the filter every 6 to 8 months. However, the filter life will depend upon the environment in which it is used.

The filter lasted approx. 6 months. It would all depend on the quality of your water. This one was used in an apt. setting with city water, so I thought is was well worth the money.

Go to Monolithic website and read up on these filters. I believe they are good for 6-8 months with the cleaning and shaking then should be replaced.

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 haven't had to replace mine as yet (just got it last week). But I will check Amazon for pre-filter and filter. I just checked and Amazon carries the filters for $33.

It depends on how often you run the unit and how much dust/allergens it's filtering out of the air. If it is always running then generally the filter should be replaced every 6-8 months.

When I bought the system it said on the box that for a family of 4 the filter should last about 1 year or something like that - now depending also of usage. I would at least change it once a year even twice in fact as I got more filters with my last order.
