It's easy to use and has helped reduce the buildup of bacteria, algae, and the musty odors that can develop after several days of use. The treatment mixes easily into the water, and I haven't noticed any added fragrance or unpleasant smell, which I appreciate. My humidifier has continued to run efficiently, and the wick has stayed cleaner compared to using plain water alone. Having two 32-ounce bottles included is also a great value, providing enough treatment to last through an entire humidifier season.

While it's very effective, it's still a chemical treatment and should always be stored well out of the reach of children and pets. I also recommend wearing protective gloves and safety glasses when pouring or measuring it, especially since accidental splashes can happen. Taking a few simple precautions makes using the product much safer. Overall, this bacteriostatic treatment does exactly what it's designed to do. It helps keep the water reservoir cleaner, reduces odors, minimizes bacteria and algae growth, and supports better humidifier performance. As long as it's handled responsibly and according to the directions, it's a worthwhile product that I would recommend for anyone using an evaporative cool mist humidifier. Review: Very effective and a good bargain - I bought this product in the hope that it would make the Essick Evaporative Humidifier that I had purchased a couple of months ago actually useful. Now what do I mean by that? How could a bacteriostat make a humidifier useful? Here is my experience. I bought the humidifier because in PA, the winters are cold, the air dries out, and I was seeing large gaps form in my new hardwood floors. Gotta get some moisture into that air! I pondered a few solutions, such as a professionally installed whole house humidifier, but decided on the Essick humidifier because it was a bargain and it suggested being capable of whole house performance. It did perform reasonably well in that regard, however, I had to stop using the humidifier. Why? Because it was altering my sense of smell. I put regular tap water into the unit, I ran it 3 days, and then I started to smell smoke. There was no actual smoke. I was just experiencing phantom odors. Not just at home, but at work, out shopping, etc. I had no idea what was causing this. Googled it ... saw that I could have a brain tumor, seizures, early onset dementia ... oh boy. I doubted that it was anything major, but one does wonder. The timing of the onset of the symptom was a big clue, though, that it was no major medical problem. I discontinued using the humidifier and waited a while. After about 10 days, the phantom odors were decreasing in frequency. This was promising. After a couple of more days, they were gone. I refilled the humidifier and waited. Within about 4 days, the phantom odors were back. I turned the unit off and pondered. Then I came across this bacteriostat. I suspected that something about the water was the source of my phantom odor problems ... perhaps some low-grade bacterial or fungal sinus/olfactory infection. So I decided to give the bacteriostat a try. BIG WIN. First I disassembled the humidifier and cleaned the base with a mild bleach/water solution. Swished some of that around in the bottle. Bought a new wick even though the original one was only used about a week (the top portion of it was orange-ish ... gotta love PA water). Turned the humidifier back on and waited. It's been running a week now and NO PHANTOM ODORS. My nose is great, the humidity is back at good levels, and the world is filled with peace and prosperity. Ok I made up the last item, but I'm VERY HAPPY about the first two!! So, for a quick hit list of PROS and CONS: PROS: It WORKS! Whatever was being aerosolized and messing up my sense of smell, it's gone and I'm super happy. I was facing stopping use of the humidifier, because it was driving me nuts smelling burning smoke on and off all day long. Inexpensive. You only use about 10 mL total per filling for my humidifier model, and this is a good-sized bottle. I think it's going to last a couple of years. For the measurement part, buy yourself a small shot-sized measuring glass. It has mL and oz and cup markings ... you can probably get one here at desertcart or certainly at the Bed/Bath/Beyond chain. Should keep the humidifier cleaner. Not going to make any recommendations for you, but I'm sure that as it inhibits bacterial growth, it's going to make cleaning the unit easier and faster. Not so much to have to clean. Pretty blue bottle. Ok that's reaching for it. But blue *is* my favorite color. CONS: Pouring. To be fair, a full bottle of anything is hard to pour in small quantities. I have this problem all the time with a new bottle of olive oil that I want to drizzle over pasta. Having read of other peoples' issues when I received this product, here is the solution I came up with: Don't remove the foil seal. I made a puncture with a pen barrel for the pour hole, and a smaller puncture to allow air to escape while pouring with the pen point. MUCH easier to pour this way. Try it and see if it helps! That's it. I can't think of a single "nother" Con. You may not have experienced the weird olfactory issues I did with your humidifier, but when used as directed, this product is just going to improve the performance and healthiness of your humidifier. Highly recommended. A Crabseye favorite! ## Features - 2 - 32 Ounce Bottles ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #8,905 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1 in Humidifier Chemicals | | Customer Reviews | 4.6 out of 5 stars 13,107 Reviews | ## Images ![Essick Air 1970-2 Humidifier Bacteriostatic Treatment, 2-Quart - Image 1](https://m.media-amazon.com/images/I/81bCYKCkfoL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this keep mold from growing in the unit?** A: I have been using this with paper filters for last 2 years and I don't see any mold. I do cleaned unit before and after season which is rssential to not have mold. if you put it away still wet after season it will get mold **Q: how many ounces is in each bottle?** A: 32 ounces per bottle **Q: Is this safe for a guitar room evaporative humidifier?** A: This is a Chloride based bacteriostat and you use such a small amount per gallon that I do not see any problem using it in an evaporative humidifier for your guitar room. We have used this product for several years in our home and have not had any problems with odor, residue on furniture surfaces or pet reactions to the proper use of this product. We evaporate 5-7 gallons of water a day through our system and have never had an issue with Essick Air Bacteriostatic Treatment. **Q: Aircare cust service: does the chemical dissolved in the bacteriostat solution evaporate into the air with the water or does it stay on the filter?** A: Essick Air Humidifier bacteriostatic is made up mostly of chlorine products. As water evaporates through the filters, small amounts of chemical may end up as deposits on the filter but the majority of the deposits are calcium from the water. The chlorine evaporates with the water, just like chlorine does in a swimming pool. I have never had any skin issues handling the old filters when replacing them. I do not wear gloves when changing the filters but if you have concerns, by all means, wear protective gloves when replacing your filters. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Helps Keep Humidifiers Cleaner and Running Efficiently, Big Difference in Filter Quality & Life *by J***O on July 9, 2026* I've been using the Essick Air Bacteriostatic Treatment in my evaporative humidifier, and it's made a noticeable difference in keeping the water reservoir cleaner between routine cleanings.

Keeps bacteria from growing and you only put in about a teaspoon so I lasts for a season or more. At least it does for me. I don't need more than one humidifier. ## Frequently Bought Together - Essick Air 1970-2 Humidifier, 2-Quart Bacteriostatic Treatment, 2 Pack (1970-2) - AIRCARE 1043 Replacement Space Saver Wick (1) - AIRCARE Space Saver Large Evaporative Whole House Commercial 6 Gallon Humidifier for Large Rooms 2,700 sq ft.
