Can one of the expert growers advise me whether I can use dehumidifier water with carnivorous plants (when I run out of rainwater or distilled).
Also, can one use municipal water with any CPs if the water has sat for a day or two (so chlorine and other scrubbing agents bleed off)?
Thanks!

Dehumidifier water is very high in toxic aluminium.
Use a TDS meter. If your water is less than 50 PPM or 20 for sensitive plants use it.
Boiling/sitting water not helpful.

Sitting water will only concentrate the dissolved solids, which is the opposite of what you want to be doing. The big problem is not the chlorine, but the high TDS levels in some tap water.

It might be worth it to purchase a RO/DI unit to lower the TDS of your tap water if you're deciding to grow hundreds of carnivorous plants.
I just buy distilled water for 88 cents at my local grocery store (Sobeys). I use 1 bottle (4 litres) every 2 weeks on average.

Thanks for the 'sage advice'
I have used tds meters before to calculate appropriate fertilizer concentrations, but the cheaper units I had access to were unreliable.
I think for the near-term I will purchase distilled or RO water. I like the idea of an in home RO filter as our municipal water supply truly sucks and during the summer tastes like a backwater bay.

Taste might just indicate organic matter, like algae and be OK. If it tastes brackish, it's likely full of minerals and bad.
