What Customers Are Saying
Customers overwhelmingly praise this humidifier treatment for preventing mold, mildew, and odors while extending filter life significantly. Most report filters lasting an entire winter instead of requiring monthly replacements, with many users noting the product lasts two or more seasons, making it highly cost-efficient despite upfront cost. Reviewers consistently describe it as easy to use with immediate results and express strong loyalty, with some using it for over five years. A few mention concerns about chemical handling and minor foaming, but these do not diminish overall satisfaction. Nearly all customers consider it essential and plan to repurchase.

It's like waving a magic wand over my humidifier.
Would RecommendSometimes you don't know that you needed something until you use it. Wow! This stuff is a winner all around. The air is fresher, cleaner, and the wick last almost twice as long saving me money. It's even easier to clean the humidifier because there is nothing to clean out. Also there is no real cost due to the low price and the bottle will last and last and last. !/8 cap full is all you need per gallon. Who knew?

Long Time Home Owner
Would RecommendI have been using Essik Air Bacteriostat in our home humidifiers for more than fifteen years! My wife suffers from very bad Dry Eyes, so we run a humidifier twelve months a year. Before using the Essik product I had tried several brands and my humidifiers would spew bacteria causing runny noses, sneezing, etc. NOT SO with Essik Air Bacteriostat water treatment. I am a most satisfied user!! Jim Gura

Essick Air Humidifier Treatment
Would RecommendIt works great! I used to get a funky mold smell every year with the humidifier, but after using Essick Air Humidifier Treatment the filter does not get moldy at all. I highly recommend.

Dangerous to use
Would Not RecommendThis may work fine, but read the fine print: "Causes irreversible eye damage and skin burns. ...Wear protective eyewear, protective clothing, and rubber gloves..." OK, why would anyone put themselves and their children at risk? Surely there are other safer alternatives. Vinegar?

Confusing Product
Would Not RecommendThe directions on the bottle state “1/6 fluid ounce (approx. 1/8 capful) …per gallon of water.” By the way, 1/6 fluid ounce is equal to 1 tsp. But the directions under Overview on this website state, “use 1/6 fluid ounce (approx. 1/8 cupful)…per gallon of water.” 1/6 fluid ounce does not equal 1/8 cup! But the answered question on 10-18-20 from Melissa at AirCare on how much to use says, “add 5 teaspoons of treatment per each gallon of water.” She also says to add the treatment to the bottles, n...

Humidifier Treatment
Would RecommendI add the recommended amount during fill ups and seems to work fine in keeping the tank clean and mold free. Read and follow the precautions on the bottle and it should work well. One bottle lasted through two heating seasons.
