Advanced Technology
Why is the SilentComfort™ HEPA Air Cleaner so Quiet?
At Honeywell, we know that quiet is important.  That's why we've designed the SilentComfort™ HEPA air cleaner using advanced No-Draft™ airflow technology and other sound-reducing features.  We want you to use the higher speeds of your air cleaner without the noise or airflow disturbances created by many other air cleaners.  On higher speeds, air cleaners provide more filtered air into the room, imprioving air quality more quickly.  By offering comfortable operation with improved performance, the SilentComfort™ HEPA air cleaner is perfect for use in bedrooms and family rooms — places where you spend most of your time.

How Quiet is the SilentComfort™ HEPA Air Cleaner?
It's so quiet that you may think it's not working!  But don't worry — it is!  Independent testing shows that the SilentComfort™ HEPA Air Cleaner is quieter than many HEPA and non-HEPA air cleaners of similar performance sold at retail (air cleaner performance based on October 1999 AHAM Room Cleaner Directory, within a 10 CADR range).

What is a HEPA Air Cleaner?
HEPA stands for High Efficiency Particulate Air.  HEPA filters are recognized as one of the most efficient ways known to remove airborne particles.  They are used in medical, laboratory and commercial applications.  HEPA filters are certified 99.97% effective at capturing airborne particles as small as 0.3 microns from the air that passes through the filter**.

Honeywell Enviracare® HEPA Air Cleaners - The #1 Choice of Physicians*
In a survey conducted by Riter Research, Inc., physicians were selected at rendom from the American Academy of Allergy, Asthma and Immunology.  Of physicians surveyed who recommend portable room air cleaners to their patients who suffer from allergies or asthma due to air pollution:

  • 93% of the Physicians Surveyed Consider HEPA Filtration to Be Extremely or Very Effective
  • 82% of the Physicians Surveyed Prescribe or Recommend Honeywell or Enviracare® Portable Room Air Cleaners

Typical Performance for This Model
Indoor air must be constantly recirculated by an air cleaner in order for it to help reduce concentrations of airborne particulate contamination.  For air cleaners of equivalent filter effectiveness, a higher Air Change per hour (ACH) rating may help improve air quality more quickly.

Room Size Recommendation:
Honeywell's minimum recommendation of 6 air changes per hour, which exceeds AHAM standards:

   Room Size (8' Ceiling)

   Sq. ft.

   Air Changes per Hour (ACH)

   11' x 17'



AHAM Suggested Room Size:

   Room Size (8' Ceiling)

   Sq. ft.

   Air Changes per Hour (ACH)

   10' x 23'



AHAM Performance Ratings
In order to assist consumers in comparing room air cleaners, the Association of Home Appliance Manufacturers (AHAM) has developed a standard rating system to measure air cleaner effectiveness, called the Clean Air Delivery System (CADR).  These performance ratings are based on independent laboratory testing.

 AHAM Certification Program
Certified Rating - Clean Air Delivery Rate
Dust: 150
Tobacco Smoke: 150
Pollen: 135

This information is provided to assist consumers in comparing room air cleaners.  These values represent performance that can be expected within the first 72 hours of operation.  Subsequent performance may vary with use.  This air cleaner is suggested for use in a single closed room up to 230 square feet.  Room size ratings assume an 8' ceiling and conform to the AHAM Certification Program criteria of 80% tobacco smoke reduction.  Higher Clean Air Delivery Rates (CADRs) provide improved performance in all room sizes.  Portable air cleaners will be much more effective in rooms where all doors and windows are closed.

Filter Replacement
Filter life depends upon use.  To maintain optimum performance, we recommend replacing the filters:
