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)

How it works:

HEPA stands for High Efficiency Particulate Air.

HEPA filters are high density paper mats composed of randomly arranged fibers and pleated in a “V” pattern. The mat is bonded onto a sturdy base, forming the core of the filter. Particles are captured on one side of the filter which prohibits them from moving through to the other side.

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 at least 99% of dust, allergens, smoke, pet dander and pollen particles as small as 0.3 microns from the air that passes through the filter.

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

Maintenance HEPA filters will need to be replaced over time, replacement time varies by model. Truman Cell filters need to be washed regularly but are permanent and never need replacing.
HEPA filter life will vary by usage and environment, including factors such as room size, the air quality in your home, or whether you have pets or smokers in your home. Replacement timing varies by model and typically comes with an indicator light reminding you when to replace. 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.

Most HEPA air purifiers come with an odor filter to reduce offensive odors from the home such as cooking and pets.  Some also have VOC filters to reduce VOCs (volatile organic compounds such as paint smells and off-gases for new rugs and furniture, and aerosol vapors) from the air.  Filter life varies with usage and environment and must be replaced.

All Truman Cell air purifiers come with either a disposable odor absorber or Helios Shield, a permanent odor filter.  Both filters help reduce odors and VOCs (volatile organic compounds) from the air that passes through it.

Sound Slightly higher noise levels compared to Truman Cell technology because more power is required to overcome the resistance that the airflow encounters as it travels through the solid HEPA filter.  But in general, sound is kept to a minimum with settings to reduce even further. 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.
