Airpura G400 Air Purifier

Description

Discover the Airpura G400: Your Compact Solution for Chemical Sensitivity and MCS

The Airpura G400 was developed around the needs of chemically sensitive users, combining powerful filtration with an exceptionally inert, odor-free design. Its premium German-sourced carbon is selected for purity and is free from odors and residual carbon dust. This allows the G400 to thoroughly filter out airborne contaminants without becoming another source of unwanted smells or emissions—an important benefit for people with Multiple Chemical Sensitivity (MCS).

The G400 also combines a medical-grade HEPA filter with an optional cotton pre-filter. Working together, these three stages of filtration address household chemicals, smoke, chemical odors, VOCs, pathogens, mycotoxins, mold spores, dust, and other common allergens.

This emphasis on material purity and composition, together with strong particle and chemical filtration, makes the G400 well suited to nursing homes, hospitals, dental offices, and other medically sensitive settings. It is equally suitable for homes and offices where chemical sensitivity and clean indoor air are a top priority.

Super-HEPA Upgrade

For those suffering from intense Multiple Chemical Sensitivity or severe allergy and asthma symptoms, an upgrade to the Airpura G414 model could offer significant improvement in symptoms. The Super-HEPA upgrade can filter out an impressive 99.99% of particles as small as 0.3 microns, providing a superior line of defense against airborne allergens.

HEGA Carbon Cloth Option

Airpura’s HEGA (High-Efficiency Gas Adsorption) Carbon Cloth represents the cutting edge in air purification technology. Originally developed for military applications, this specialized woven activated carbon material delivers exceptional performance in removing harmful airborne contaminants.

Our military-grade HEGA filters exceed industry standards (IEST-RP-CC-008-84), providing superior protection against:

• Volatile Organic Compounds (VOCs)
• Chemical contaminants
• Odors
• Viruses and bacteria, including SARS-CoV-2
• Gas-phase pollutants

Key advantages:

• Achieves up to 20% higher adsorption rates when used in conjunction with granular carbon
• Maintains peak performance in humid conditions
• Utilizes electrostatic (van der Waals) forces to trap and neutralize viral particles
• Features an enhanced surface area through fine mesh design

This advanced filtration solution combines military-grade protection with proven effectiveness, making it ideal for demanding air purification applications where maximum contaminant removal is essential.

The Airpura G400 absorbs and traps the following from your environment in spaces up to 1000 sq. ft:

• Airborne Chemicals & Gases: Removes over 4000 chemicals including ammonia, formaldehyde, benzene, methylene chloride, toluene, xylene and perchloroethylene.
• Airborne Particulates & Allergens: Includes pet dander, mold, mycotoxins, dust, pollen, pesticides and even asbestos.
• Smoke: Including tobacco and marijuana smoke, smoke odors and their chemical byproducts.

3-Stage Filtration — Including G414 Super HEPA Upgrade Option:

1. Pre-Filter — An optional organic cotton pre-filter grabs and traps large particles such as hair, lint, dust and dander,  and in doing so extends the life of the HEPA and carbon filters. Change every 12 months and vacuum clean for better performance.
2. Carbon Filter – 8 lbs. of odorless German carbon in a 1” deep, high-quality carbon bed to absorb airborne chemicals, odors, VOC’s and gaseous fumes. The carbon filter will typically need changing every two years depending on air quality and usage.
3. True HEPA Filter — Choose Between Two Levels of HEPA Filtration
   • G400 Standard HEPA: Equipped with a 40 square foot medical-grade True HEPA filter, the G400 is able to trap up to 99.97% of particles down to 0.3 microns. Has a lifespan of approximately 5 years.
   • G414 Super HEPA: Upgrade to the G414 Super HEPA filter to remove up to 99.99% of airborne particles that are 0.3 microns in diameter and smaller. This is the recommended option for those with MCS (Multiple Chemical Sensitivity) or those looking to capture the smallest of airborne particulates.

German Carbon Features:

• Activated carbon treated with oxygen
• Odorless and Dustless
• Formulated specifically for the chemically sensitive
• Inert composition

The Airpura Difference – Built for Health & The Environment

• No Off-Gassing: Built without the use of plastics, rubbers, or adhesives associated with emitting toxic gasses or VOC’s. The only exceptions include the presence of some materials required to meet UL, ETL, CE and CSA safety standards.

• Felt Gaskets: All gaskets are made from felt instead of rubber, which helps seal each component and create highly effective air filtration. Felt gaskets have the ability to further reduce off-gassing as well. Additionally, these units have fully sealed filter, motor, and electrical chambers.

• Metal Housing: Constructed entirely from solid steel on the outside, the reduction of plastic components in favor of metal housing contributes to the decrease in off-gassing. The all metal housing is also a more environmentally friendly material in general as it’s 93% recyclable.

• PCB Free: Electrical equipment often includes capacitors that are made from PCBs; polychlorinated biphenyls. PCBs have been associated with a variety of types of cancers. Airpura capacitors are all made with entirely PCB-free materials.

• Pure Air Flow: Engineered so that the units motor is positioned away from the flow of air. Most air purifiers are designed in a way that as air passes over the motor, new impurities are picked up before exiting the unit. Airpura air purifiers were designed to prevent this.
