How Fog-Proof Mirror Systems Work

ClearlyYou™ Mirror Defoggers transmit gentle warmth across the mirror's surface. This prevents the steam's moisture from collecting on the colder mirror surface while you bathe or shower. Self-adhesive backing allows easy application to any wall-hung mirror in just minutes. With the ClearlyYou™ system installed in your bathroom, your mirrors won't become an inconvenience as the room steams up.

Frequently Asked Questions

Can a mirror defogger be controlled with a low-voltage dimmer switch?

The mirror defoggers are not designed for use with dimmer switches or with any low-voltage control. 

Can I put a mirror defogger in my shower?

No. Mirror defoggers are not rated to be installed in wet locations like a shower enclosure.

Can I trim the mirror defogger?

No. Mirror defoggers can't be trimmed and the proper size needs to be selected to fit on an open, unobstructed area on the back of the mirror.

Can I use multiple defoggers on the same mirror?

Yes, but please make sure not to overlap multiple heating elements over each other.

Can I wire it to the lighting circuit?

Yes. In fact, this is the most common way to operate a mirror defogger.

Can you attach it to the back of a medicine cabinet door?

No. Mirror defoggers are designed to be mounted and wired to a fixed, wall-mounted mirror.

How does a mirror defogger work?

An ultra thin electric heating mat is attached to the back of the mirror, which transmits gentle warmth across a mirror’s surface to prevent moisture from condensing on the mirror's surface during a shower or bath.

How do I glue a mirror to the wall and still have a defogger on it?

If you're gluing a mirror to a wall, simply apply adhesive to the mirror backing, not covered with the mirror defogger.

How quickly can a mirror defogger defog a mirror?

The mirror defogger will begin to defog the mirror within 5 minutes of operation.

How thick is the box on the back of the heating mat? Does it prevent the mirror from lying flat or flush against the wall?

The electrical junction box should be installed inline with the Mirror Defogger’s lead wires and box. The box at the back of the defogger is meant to be located over the electrical box in the wall. This way it will be in the electrical box and not interfere with the defogger being flush with the mirror and the wall. The location where the wires leave must be entirely within the area of the new electrical junction box.

What is the best way to keep bathroom mirrors from fogging up?

Installing a heating system behind your mirror is the most reliable way to avoid a foggy mirror. Typically, mirrors fog up because they are much cooler than the steam in a bathroom after a shower or bath. The cool surface of the mirror causes the moisture in the steam to condensate in the form of fog. A heated mirror will prevent this condensation by being as warm, or warmer, than the steam. 

What is the length of the cold lead for a mirror defogger?

A mirror defogger cold lead is 36 inches long.

What is the polarity of this radiant heating product?

Electric-resistance heating cables and systems have no polarity. This includes all current WarmlyYours heating elements.

Shower mirror

ClearlyYou™ Mirror Defoggers

I use it behind a shower mirror. Does not seem to take away the mist as well as I thought it would. Maybe it has to be on for a longer period of before getting in?


Great product!

ClearlyYou™ Mirror Defoggers

Great product! Does work better for new construction because of the need for power. But I put it in an existing bathroom during a refurb.
