Similarities Between AC5250PT, AC5000E and AC4825

When you’re looking to buy a GermGuardian air purifier that falls within the 4000 and 5000 series there are multiple features that you’ll enjoy no matter which product you choose.

The most notable feature is the 3-in-1 air cleaning system. This unique process includes:

  • True HEPA Filter that captures 99.97% of microscopic particles and allergens that cause breathing problems, such as dust, pollen and pet dander down to .3 microns in size
  • UV-C Light that kills airborne germs, bacteria and viruses (including staph, influenza, rhinovirus and pneumonia) making your home a sterile, healthy living space. (Read more about germicidal ultraviolet lighting.)
  • Charcoal Filter that absorbs odors from pets, cooking, smoke, etc. ensure your home smells fresh and clean

Multiple Cleaning Levels

Each one of these air purifiers comes with a fan speed control. This enables you to adjust the air cleaning level to suit your specific needs. The low setting is ideal for nighttime use in a bedroom because it provides the quietest operation. Medium mode is best for continuous use throughout the day and the highest setting is best to use when a major flux of airborne contaminants enter into a room. This includes everything from a smelly pet, to cooking odors, smoke, an open window or door that allowed pollen or other allergens to come in, etc.

Note: Each GermGuardian air purifier model offers a different set of fan speed control levels (3 or 5). This specification is outlined in the section on product differences below.

Energy Star Certified

All of these air purifiers hold the Energy Star Certification and meet strict guidelines set by the United States Environmental Protection Agency. This ensures that no matter which product you choose, you’ll have an air cleaner that’s energy efficient and cheap to operate.

Warranty and Free Support

  • The AC5250PT and AC5000E provide the same air purifying power. You”ll enjoy the same quality of clean air regardless of which device you choose.
  • The major features you’ll be giving up by choosing the AC5000E over the AC5250PT include the pet pure antimicrobial treatment, digital controls, a programmable timer and 2 additional fan speeds. These features are a nice bonus, but not a must-have for every homeowner. The AC5000E can save you $50.
