Product review (3 stars): Extend their life
For those of you getting only  a week or two of usefulness from these filters, on a whim I ran one through my dishwasher using regular detergent and a few dishes. I let it go through the hot dry cycle, but think it might be better to pull it out before that. Some of the plastic screen was distorted, but not badly. The webbing was disturbed a bit but not badly. I put it back in the machine on the next filter change and it has been acting like a brand new one. I have the little humidistat gauge on my unit, so as the filter goes bad it shows up on the gauge. My next test is to see how many times it can survive the DW. Will shorter cycles work? For those with high amounts of calcium in their water vs the manganese I have, maybe some vinegar instead of detergent. And maybe save up 2-3 filters and run a dedicated cycle. Those with aluminum cages on the filters might not like the DW detergents. Try it and add an opinion about it. I do think the engineering of these units where they rely on capillary action to pull water up into the filter is ridiculous. My water doesn't have mold or mineral deposits aside from the orange maganese, it just gets dirty with dust kicked up by our traffic and the dog. The filters do get a brown tinge on the top as they stop working. I'll also get a colorless, odorless bioslime in the reservoir and presumably in the filter. This may be what is being washed out as much as anything. But I'm going with the DW for now, otherwise I would go through 12-15 filters a season. I tried the silver nitrate balls in the reservoir, but they didn't help.
