Essick Air 1970-2 Humidifier, 2-Quart Bacteriostatic Treatment, 2 Pack, Clear, 2

Seems to work well. No problems with it.

We live in an area with very low humidity most of the time so use a portable evaporative cooler and a home humidifier regularly. If you don't the static electricity from getting off the couch can be lethal. After a week or so our humidifier and cooler would get very slimy. Since we found this product we can keep everything operational for weeks without having to constantly empty them and clean the slime out. It only takes a teaspoon per gallon of water and there are no negatives as far as chemical smell. You can't tell there is anything in the water. We have been using it for several years and no tumors or other issues. Thank you for a great product.

Works great, disinfecting odor is mild and evaporates quickly after adding,

This is my mothers second order of these. Great value but it really does work. she puts it in her large humidifier but also her little ones as well it really cuts down on the water dust sports and regular dust around the house. Keeps her large humidifier clean and has never had a problem with it after 9 years of use and she believes its because she used this to keep it clean and running well. You only use a cap or 2 full but she orders more because it takes so long to get and never wants to run out

Just about to order more.
