HEPA Filter vs. Truman Cell®: which fits your needs?

Oreck offers its customers a full line of air purifiers that use either Truman Cell® technology or True HEPA filters. Which option is right for your home? Compare and decide!

  Truman Cell (EP)
Oreck Products: ProShield® | ProShield® Plus | DualMax
How it works:

The Truman Cell® is Oreck's exclusive EP or electrostatic precipitator filter.

It is composed of a series of metal plates and wires. Particles from the air are positively charged as they enter the cell wires and then are attracted to negatively charged plates where they stick until cleaned off.

What it does:

Captures dust, allergens, smoke, pet dander and pollen particles as small as 0.1 micron from the air that passes through its filter, pulling them out of the air like a magnet.

Maintenance Truman Cell is permanent, never needs replacing.
All models have a 30-day indicator light to let you know when it's time to clean the Truman Cell®. Simply remove, wash with soap and water, rinse clean, then re-insert into the unit.
odour

Oreck air purifiers with Truman Cells all come with a disposable odour absorber (ProShield model) or Helios Shield, a permanent odour filter (ProShield Plus and DualMax models).

All of these odour filters help reduce odours and VOCs (volatile organic compounds) from the air that passes through it.

Sound Generally quieter than air purifiers that use HEPA filters because its technology and design (you can see through the metal wires of the Truman Filter®) requires less power.
Efficiency The Oreck DualMax is Energy Star® certified.
