## Overview

The LEVOIT 3-Pack Humidifier Water Softener cartridges use 10g of cation exchange resin to effectively remove calcium and magnesium ions, reducing white dust and scale buildup in humidifiers. Compatible with most top-fill humidifiers with tank openings larger than 3.5 cm and capacities up to 2 gallons, these cartridges feature an ultrasonic welded casing for safety and durability. Integrated with the VeSync app, they provide smart replacement reminders to maintain optimal performance, ensuring longer humidifier life and healthier mist for your living or working space.

## Description

Water softeners can soften calcium, magnesium and other minerals in water, reduce scale and white dust in the mist, which can not only make the sprayed mist healthier, but also extend the service life of the humidifier

Review: These work fantastic! I have horrible hard water but I use my water filtered from the fridge and there is no white film or mineralization build up.
Review: Seems to work, I change them monthly and not seeing any white dust. I use Distilled water, when I get to a store and Britta filtered water. Not seeing much mold or decolorization build up, either, so seems to help and I'm not a fanatic at cleaning the machine.
