Austin Air Allergy Machine Replacement Filter Pack (FR405)

Austin Air Allergy Machine™ HEPA/HEGA Filter Pack (FR405) replaces all filters that come with the Austin Air Allergy Machine™ (HM405). The Allergy Machine’s 4-stage filtration system is designed for best all-around protection from allergies and asthma. The system integrates military-grade carbon cloth with true, medical-grade HEPA to clean air of the smallest airborne particles and chemical gas contaminants to become HEGA (High Efficiency Gas Absorption).  Included in the Allergy Machine™ 4-Stage Filter Pack are:

• Stage 1 – Large Particle Permafilt Pre-Filter – removes particles easily seen by the eye (dust, hair, pet dander)
• Stage 2 – Medium Particle Pre-Filter – removes small to medium-size particles (pollen, molds, other spores)
• Stage 3 – 60 sq. ft. of Certified HEPA – removes allergens, bacteria, viruses, and other particulates:
• 99.97% of all particles larger than 0.3 microns
• 95.0% of particles larger than 0.1 micron
• Stage 4 – Military-Grade HEGA Carbon Cloth – absorbs more gases, odors and chemical contaminants

Because you see the pre-filter through the air cleaner’s grille, choose the Black filter pack for Black-Silver-Blue units or the White filter pack for Sandstone-White units.

Features:

• Replacement Allergy Machine™ HEPA/HEGA Filter Pack (FR405) includes all 4 filters to replace the set that comes in the unit
• Includes 60 sq. ft. of true, medical-grade HEPA to filter 99.97% of allergens, bacteria and viruses to 0.3 microns

• 2 pre-filters trap larger particles and prolong the life of the HEPA
