How It Works

Run your finger along the top of a ceiling fan blade.

There is a grey strip up there. There is on every fan in the house.

Most people assume it is dust that landed on a blade nobody cleans.

It is not. It is a sample of the air in that room — and the fan collected it.

Why the dust ends up there

A ceiling fan moves more air through a room than anything else you own. It runs for hours at a time and pulls the whole room past its own blades, over and over.

Two things then happen at the surface of the blade.

The air stops moving. Right at the surface of any moving object there is a thin layer where the air is effectively still — a fraction of a millimetre thick. Dust that reaches it settles out.

The blade builds a charge. A blade turning through dry air picks up a static charge, and that charge holds fine particles in place.

So the fan catches your dust. That is what the grey strip is made of.

And then it gives it back

A fan blade is a few inches of hard, flat plastic. It has nowhere to put anything.

So it saturates within days. And every time the fan starts again, it returns the load to the room.

That is why the dusting never seems to hold. You wipe the surfaces on Sunday and it is back by Thursday, and it feels like you are doing something wrong.

You are not. The biggest air-mover in the room has been handing it back to you.

What about the furnace filter?

Most people believe the filter they change every month is cleaning the air in their home.

It is not. It is there to protect the furnace from debris. And it only moves air at all while the heating or air conditioning is actively running — which for much of the year is almost never.

The thing running all day is the fan above your head, and there is no filter in it.

What Bladeloft does

It gives the blade somewhere to keep what it catches.

A pad of activated carbon fibre attaches to the top of each blade. The surface that was already collecting your dust can now hold onto it instead of releasing it.

Same fan. Same air. Nothing plugged in, nothing running, no noise, and no machine to buy filters for.

The part you can actually see

Peel a pad off after a month.

The pad is grey. The blade underneath is clean.

Almost nothing else in this category can show you that.

Fitting them

1. Wipe the blade. Top surface only, and make sure it is dry.

2. Peel and press. One pad per blade, pressed firmly along its full length.

3. Turn the fan on. Replace each pad when it has visibly darkened.

Under a minute per fan. No tools. Comes away cleanly when you remove it.
