Essick Air 1970 Humidifier Bacteriostatic Treatment, 1-Quart

This is a necessary product if you have a stand alone evaporative humidifier. Make sure you use the water treatment recommended by the manufacturer since not all humidifiers are the same. This keeps bacteria and algae out of the water, and therefore off the filter and unit. Once you get mold or any growth in there the unit just kicks it back into the air where you're breathing it in. Very unhealthy. I ordered it online to pick up at the store and was happy that it got there a day earlier than expected.

This product has the correct formulation to avoid water contamination. The water which is not recirculating, stop water, contaminates in a couple of hours. This product avoid that. It is a good product at a good price. Keep the bottle well closed
