If you use an evaporative humidifier, this BestAir 3BT water treatment is a must-have.

It's the original BT formula, and it comes in a 2-pack of 32-ounce bottles—so you've got plenty to last through the dry season.

Made right here in the USA.

This stuff does a couple of important things.

First, it eliminates odors—no more musty or stale smells coming from your humidifier.

Second, it improves the effectiveness of your humidifier and wick, helping it release more moisture into the air.

That means better humidity output and less strain on your machine.

It also prolongs the life of your wick and the humidifier itself by keeping mineral buildup and bacteria in check.

You just add about 2 teaspoons per gallon of water every time you fill the tank.

Simple and effective.
