Essick Air 1970 Humidifier Treatment (4 Pack)

J'ajoute tel que recommandé par le manufacturier la quantité dans chacun de mes humidificateurs. de plus, ça laisse une très petite odeur de fraicheur et effectivement, il y a beaucoup moins de calcaire qui s'infiltre sur les rebords et l'eau reste propre plus longtemps. Évidemment, j'ajoute de l'eau tous les jours dans mes humidificateurs donc, il est donc difficile pour l'eau de devenir pas bonne. Je trouve ça efficace.

Began using a humidifier this season, and ordered a four pack of treatment as the second bottle of Essick #1970 purchased on 10/28/25 was running low. Noticed the "heft" of the bottles was off. After the second bottle went empty I weighed it, and the four new bottles. The empty bottle weighed 75.5 grams None of the four exhibited signs of leakage, and all their seals were intact, but weights were all over. One bottle clocked in at 944.1 grams (which is what one would expect for a bottle volume of 946 ml), but the others measured 827.4, 807.8, and 788.4 grams. This averages to about 11% less that it ought to be. The product itself is effective, but I'm taking off one star due to the above. It also calls into question whether the percentage of active ingredients also exhibits this large an amount of variation.

It foams, so put it in last. I'm impressed. Before, the bottom of my Vornados were yellow, the filters were yellow, and the filters quickly got hard. So improved with this! Two teaspoons in each water container.

Works as advertised

I live in a dry winter climate and use this with our humidifier. It is a great product, and I have been using it for years!
