One of the advantages the Romans had in their efforts to conquer the known world was silver flasks in which soldiers kept and thus preserved water and wine. Silver is a potent bacteriostatic element. Silver dust distributed in some longer-lasting water filters prevents filtered-out bacteria from growing. This product has kept my humidifiers clean and clear (I have two larger ones in my mobile home to keep humidity at 50-55%) and tripped the life span of the somewhat expensive wicks. Early year I also added a similar amount of bleach and that oxidized the wicks and the resulting detritus defeated the silver drops. 3 month into this cold Vermont season my wicks are hardening a bit but are still white and working well. My water source is a park well, the water is CL treated and passes state inspection but can run dirty for a while when a pipe freezes or someone hooks on or off. The water is potable but not filtered. I LOVE THIS PRODUCT!

This stuff is just amazing. It almost completely stops the slime from forming so fast in my (cool & warm) humidifiers. It’s still good practice to maintain and wash out all the parts but this definitely cuts down on having to do it every other day.

I used this with distilled or purified water in my humidifier. No cleaning issues to date.

We have two Humidifiers. one is a Sharp large whole room unit and the other a smaller unit used to keep the humidity level up next to tropical air plants. Previously, they both would get a nasty, smelly orange colored bacterial/fungal mass growing within the units, especially on the water dispersal filters. It took a lot of time to clean both every month, so I decided to try this product.First, I thoroughly cleaned each one per usual. Then added six drops to each container and filled them with water. Each day as I refilled the water containers, I added six more drops and placed them back in each unit.At the end of the first month I checked the water dispersal filters and both were free of any of the orange growth and no smell. There was only the usual mineral deposits from the evaporated water. End of month two, still clean. End of month three, still clean, but just to be on the safe side, I did my usual cleaning of each unit.This Silver in this solution really works, don't know how or why, but it does. I highly recommend this product to keep your humidified air and humidifier clean.

Seems to help with the slimy build up bit cannot say it is a miracle did not notice it helping with the white dust
