Not sure. Have had mine for 3 months and it is doing fine. No smells. Be sure to "click" the top closed to eliminate fruit flys.

We use this Compost Caddy in our office of about 70 people. We started using it about 2 months ago and have not yet had to change the carbon filter.

There is a pre-filter that you have to change. There is an indicator to tell you when to change filters. How often depends on what setting you run. I run mine at medium 24/7, high for 1 hour after vacuuming. I change filters about every1 1/2 - 2 months. They're not expensive.

This filter is intended to be changed every 12 to 24 months. It is recommended that the average household change it every 12 months for optimal performance and 18 months for optimal value.

I change mine every 6 months but it depends on the hardness of your water. The filter can not be serviced. I usually recycle it with my plastics.

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

I generally change mine every 3-5 years, but it all depends on the level of pre-filtration, the level of chlorine passing through the membrane, the temperature of the water. I use a .5 or 1 Micron Carbon Block pre-filter and change it every 6 months. TFC Membranes have a very low tolerance for chlorine, so if you are not using a quality Carbon Block pre-filter, the membrane will not last as long.

According to the PetSafe FAQ, it states the charcoal filters should be changed every 2-3 weeks, and the foam less frequently, like if you notice more debris in the bowl.

The unit includes one HEPA and one carbon filter. I ordered the additional filters for replacements. The carbon filter should be replaced after three months of continuous use, and the HEPA should be replaced after 12 months of continuous use. Note: The front panel has lights to indicate when a filter is due to be replaced. It glows yellow for a several weeks then changes to red, so you get plenty of advance notice that a new filter is due.

The instructions state the filter should need to be changed every 6 Months. I bought mine in December 2012 and have not changed the filter yet. The unit has four lights that indicate when the filter needs to be changed. Mine is only on the second light indicator. I run the unit 24/7 on the second of four speeds, and wash the foam pre-filter every month.

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)

This filter controlled odors for about 3 months. Once the carbon was depleted, (no longer controlled odor) it had to to be replaced. No need to clean, it either works or it doesn't.

I also use this for a red eared slider turtle. All of the filter media I change at different times to allow the "good" bacteria a chance to do their jobs and not "shock" the water with all new stuff. The carbon I like to change at least every 4 months. The polishing pads if you use them I change every month and the foam filters I will rinse every month or so, but change out with the carbon every 4 months along with the carbon. This is a great filter system! Let me know if you have any other questions and I hope you found this helpful!

I use this in my drinkwell 360 water bowl and it recommended I change the carbon every two weeks, but I usually do it once a month. I find it still functions properly in that timeframe.

The heating & air conditioning system I have recommends every 6 months. I know if you don't change them when the filter is dirty it will shorten the life of some components, particularly the fan motor due to the additional load caused by restricted air flow through the filter.

I haven't had to replace mine yet, but you would just call the company and tell them which model you have. They would send you the correct filter. I received an e-mail reminder after just a few months also, but wasn't ready to replace the filter yet. What you will be replacing if you have the carbon block, is just another carbon block filter like the one that you already have.

The manufacturer suggests changing the filter every six months. I waited for a year. A light will come on to let you know the filters need to be changed. After you change them, you will need to reset the light.

I haven't noticed either way, I do use s charcoal filter at all times, replace it ever three months, but think I'm gonna switch to every 3 months
