View Full Version : What's the bottom chamber of the mighty mite?

I recently purchased replacement filters for the mighty mite for around $27.99 plus shipping. Upon removal of the old filters there appears to be a huge filter on the bottom. I am assuming this holds the filmtec ro membrane. If so, How often does this get replaced? I am positive that at least 1300 gallons have been filtered by this unit.

They say it should last 1-3 years (I think)but I found that mine last just about a year. Just recently bought a new ro/di. Mighty might is good but my tds stays at zero for only a few months before I have to start changing filter. My water is crappy where I live.
