Amaircare AirWash Whisper 350 HEPA Air Filtration System

Amaircare AirWash Whisper 350 HEPA Air Filtration System


Indoor air can oftentimes be up to 5 times more polluted than outdoor air. With the AirWash Whisper 350 you can now purify the air in your entire home! The AirWash Whisper 350 can operate either as a “free standing” unit or can easily attach to your home’s central heating system. Powerful HEPA filtration removes allergens, bacteria, viruses, mold spores and fungi in a multi-stage filtration process that starts with pre-filtering large particles and ends with the filtration of harmful VOCs found in the home.

Amaircare’s “perfect seal” construction guarantees HEPA performance by ensuring that 100% of air passes through the HEPA media. Filtered air is then fed back into your home’s air supply through your central system, resulting in significant reduction in air pollution.

14.5”W x 14.5”D x 27.5”H. 30 lbs. Available in Black. Made in North America. 5-Year Warranty.

INSTALLATION OPTION: INCLUDES A COMPLETE AT-HOME INSTALLATION KIT WITH CLEAR INSTRUCTIONS FOR AN EASY "DO IT YOURSELF" INSTALL! Professional installation option available (select Purifier with Contractor). An authorized and qualified HVAC contractor hired by Allergy Control Products will perform the installation for you!

Extra Info

Continuous operation motor fan provides 350 CFM (cubic feet per minute) of delivered airflow. Air changes per hour (ACH) will vary from 0.53 ACH (5000 sq ft) up to 2.63 ACH (1000 sq ft). 0.53 ACH provides good cleaning results for people without sensitivities, while a higher ACH is recommended for people with sensitivities. The AirWash Whisper 350 produces just over half of the ACH than the larger 675 model for equivalent room sizes.

Constructed of durable steel with duct connections that include an 8” Duct Collar (intake) and 6” Duct Collar (outtake). An insulated cabinet offers whisper quiet operation. Eco-friendly, energy efficient, and produces no ozone.

Note: This Amaircare filtration system is an additional filter, and does NOT replace the filter in your existing air handler/furnace/central system. We recommend the Allergy-Free® Aller-Pure® Gold Permanent Filter or the Allergy-Free® Aller-Pure® MAX Disposable Filter when it comes time to replace the filter in your existing central system.


Filter Replacements:
  • Pre-Filter: every 12 months (pre-filter is washable, but should be replaced if worn or heavily soiled)
  • HEPA Filter: every 2-5 years (depending on use)
  • Inner Carbon Filter: every 6 months.
Consider purchasing the Annual Filter Kit containing 1 Pre-Filter and 2 Inner Carbon Filters to keep purifier running at maximum efficiency for a year.
