Our Verdict
This product is not a humidifier. It is a water treatment solution you add to your existing humidifier's tank. Keep that in mind before buying.
The Ketostat Humidifier Cleaner comes in a 4 oz bottle. It lasts about 140 days. You add drops based on your tank size.
It works with all humidifier types. Ultrasonic, evaporative, cool mist, and warm mist units all work. That makes it flexible.
The formula is non-toxic and made in the USA. It is safe around kids, babies, and pets. This matters for families.
At $7.99 for 4 oz, you get twice the product compared to many 2 oz competitors at the same price. The value per ounce is strong.
You need this product alongside a humidifier, not instead of one. If you already own a humidifier, these drops help keep the water clean.
