Electrostatic Precipitators

"Electrostatic precipitators will save you money!"

Save money by not having to buy costly replacement filters. An electrostatic precipitator air cleaner allows you to clean the air using electronic cells that can be washed... not thrown away.

The electronic cell is a magnetically charged strips of metal that collect airborne particles.  Filters never need replacement, though they must be washed about every 3-6 weeks.

How Electrostatic Precipitators Works...

As air enters the electrostatic precipitator, the particles pass through an electrical field that gives an electrical charge to the particles. The charged particles pass through a series of alternately charged collector plates. Particles are repelled by plates with the same polarity and attracted to plates with opposite polarity similar to how a powerful magnet works.

Dual-stage electrostatic precipitators include two parts: the charging and the collecting sections. In the charging section, the incoming smoke, grease, mist, and other particulates pass by ionizer wires which impart a positive electrical charge to these contaminants. The positively charged contaminants are then drawn through the collection section which contains a secondary electrical field with negatively charged aluminum plates. Since opposite charges attract, the positively charged contaminants collect on the negatively charged aluminum plates, removing them from the air stream.
