Product review (5 stars): I was soaking the units in vinegar to clean it out to get a good steam flowing
Had to clean my humidifiers at least once a week it seems for the last year or two every winter to keep them running well. I was soaking the units in vinegar to clean it out to get a good steam flowing. After I found these, I plopped these in and the humidifiers ran great for the whole winter. Kept a great steam without having me to clean them. Definitely recommend these!!
