In the last article, we talked about how your dehumidifier can provide you with a steady, renewable water supply for “free” even during drought conditions – and there’s very little you need to do to keep that water supply clean as long as you follow a few general “best practices.”

Follow these “best practices” to make sure your condensate water is clean and safe to use

Run your dehumidifier if it’s been idle first

If your dehumidifier has been sitting idle, run it for three days before you try to use the condensate water from it. Dehumidifiers that are allowed to sit for more than a couple of days should be dried out as completely as possible in order to discourage mold growth.

Test the condensate to make sure it’s free of contaminants

The Environmental Protection Agency defined safe contaminant levels in drinking water through the Safe Drinking Water Act, established in 1974. Individual states can establish their own standards if they are at least as strict as the EPA’s.

Contaminant levels should be well within acceptable limits as long as your dehumidifier is in good working order and has proper filtration. However, it’s always a good idea to test condensate water for heavy metals, nitrates, and bacteria – and state law may require you to if you are a commercial grower.

Keep your dehumidifier and filter clean

Your dehumidifier will produce condensate water that can be used as-is, provided you keep the filter in place and clean regularly. Dust, bacteria, and other pollutants can contaminate condensate water if the dehumidifier’s filter is absent or not maintained properly.

Keep the filter in place, and follow the filter guidelines for it; clean or replace the filter as directed.

Keep your dehumidifier running continuously and recycling water

Why? Because just using and reusing condensate water over and over again keeps it clean. As long as you always use a high-quality, clean air filter during operation, the constant recycling of the dehumidifier’s condensate water discourages mold growth.

Don’t overlook a ready, renewable, “free” water supply for your plants, especially if you’re dealing with drought conditions. The condensate water from your dehumidifier is always available. Best of all, it’s free, clean, and safe – as long as you keep just a few best practices in mind.
