For several years we have used a large humidifier during the winter months. Despite frequent cleaning and care, we had to replace the humidifier filters every few weeks. We started using the Holmes Bacteriostat last winter and only had to replace the filter a single time, three-quarters of the way through the winter.

Follow the directions on the bottle and not only save money by not having to replace the humidifier filters as often, but it can also save you from breathing mold spores growing on an untreated filter (before the filter even looks like it needs changing).

From the bottle's label:

Holmes
Humidifier Water Treatment
Model S1705

* Prolongs the life of wick filters and warm mist heating systems
* Helps prevent lime and scale build-up
* Provides easier cleaning

My motivation for buying the Treatment was to increase the lifespan of the wick. I was only getting a few months life from a wick, using about two per winter. Using the Treatment, one wick is lasting more than one winter.

And the bottle lasts more than a winter, so it's worth it.

I hate to recommend W*lmart, but I bought my last bottle there for less than $2. That was still during the end of the humidifying season. Guess I should have bought two. I also bought their last half-dozen HM3600 humidifier wicks for $2 each (in July), when you couldn't find them for less than $12 anywhere on eBay.

I'll need another year to determine just how much longer the wicks are lasting, now that I'm on the Treatment. I just checked my wick. I think I used it for almost all last winter. It's just a little soft all over, but no serious deterioration. And no smell, just in case you're counting.

The instructions recommend adding a capful with every 3 gallons of water -- as a start -- and then after a while, you're supposed to determine whether your water needs more or less. I used a little less, and it still did the trick for my wick, apparently. My water is very soft. The instructions say harder water will require more Treatment. Granted, that's not a lot of guidance.

I didn't know if it's allowed to combine bactericide with the Treatment, so I didn't. Between the Treatment and being careful not to allow the humidifier to sit with water if it was turned off, the water never got smelly.

We could not find this item anywhere then i looked on amazon.com and here it was. You have to use antibacterial even when you get a ball with the machine that is said to do the job.

I love this product. I like the larger bottles and it really makes our room clean smelling not musty and molded. Our maching stays super clean and free of all bacteria and molds using this. I would not be without it.

If you are using a humidifier and they say you do not need to add chemical, wrong. Buy this and you will see the difference and how clean your machine and air stays.

Keeps my humidifier smelling fresh and clean all the time. I highly recommend this product. (Be sure to add after filling the contained though or it will bubble up.)

Before we tried the S1708 in our humidifier MA0800, we had to replace the filter about once per month. I would buy a case of 6 filters for over $60 each winter season. Since our baby was born we have decided to leave the humidifier running year round. I have used a bottle of this and am now ordering another and have only used 2 filters this entire year. I went to change it like normal, but the filter was like new. The only time I've had to change the filter is when we left it off for a few weeks with water in the tank.
Great product that saves me money. Thanks Holmes!

HIGHLY RECOMMEND!!!

This bacteriostat works great for humidifiers that simply blow air through a wet filter (not for use with a "cool mist" humidifier). It has a slight odor that goes away after about 30-45 minutes after you add it to the water and start the humidifier. After about three months, it has worked very well to keep our two humidifiers free from musty odors or growth.

It helps to keep the minerals down to a lower level in your humidifier so that the parts don't calcify as quickly as they would otherwise. I've used the product for three years with good results. I still have a mineral build up, but we live in an area that has very hard water and I expect those results. I think you'll like it.

I am using it in a wick type of humidifier. Use to have problems with a moldy smell from the humdifier and I could see black stuff growing on the wicks. Used it for the whole winter 2010-11 and found it completely eliminated the smell. In addition it kept the wicks from getting the black discoloration. I use it with RO water and the wicks will last the whole winter. Previously I would have to change the wicks monthly during the winter months due to a combination of the hard water deposits from the tap water and the mold. Installed a RO water filtration system(another story)and started using this. So this has saved me the cost of new wicks in addition to getting rid of the smell. It also reduces the slime/algae that forms in the tank where the wicks sit. The label says not for use in heating and atomizing humidifiers. As far as the active compound it is a widely used disinfectant in a large number of household products. Of course mold itself is also dangerous. The dosage is very low just a capful per gallon but that seems to do the trick.
