Discover the Airpura V400: Your Compact Solution for Chemicals & VOC’s

Ever stop to consider what’s in the air you breathe at home? From everyday items like cleaning agents, PVC, and adhesives, to building materials and plastic degradation, your indoor air may be quietly contaminated with an unhealthy mix of chemical pollutants. Enter the Airpura V400 air purifier, your defense against harmful chemicals, VOCs and particulates. Utilizing a combination of specially treated carbon and True HEPA filtration, the V400 works tirelessly to filter out heavy-duty compounds like formaldehyde and benzene, as well as mold spores, pet dander, pollen, dust and other allergens.

But the V400 isn’t just for everyday pollutants. It’s also your shield against the harmful effects of wildfire smoke and the hazardous chemical byproducts that come with it. Smoke and ash can transport chemicals into your surroundings that cause everything from minor headaches and congestion to serious respiratory complications. The V400 is equipped to quickly neutralize these chemical compounds and restore your indoor air quality to safe and healthy conditions.

Combining such powerful air purification technology with a minimal footprint gives the V400 unparalleled versatility in its class. It’s sleek, compact size and lightweight portability allow the V400 to easily adapt to any environment in spaces up 1000 sq. ft., ensuring pollutant-free surroundings for you, your family and co-workers. With the Airpura V400, you can breathe easier knowing you’re protected.

The Airpura V400 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 Comprehensive Filtration:

  1. 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. It measures 570 sq. inches and 1 inch deep. Change every 12 months and vacuum clean for better performance.
  2. Carbon Filter – 8 lbs. of activated carbon in a 1” deep, potassium iodide impregnated carbon bed to absorb airborne chemicals, odors, VOC’s and gaseous fumes. The carbon filter will typically need changing every 2 years depending on air quality and usage.
  3. True HEPA Filter – Equipped with a 40 sq. ft. medical-grade True HEPA filter, the V400 is able to trap up to 99.97% of particles down to 0.3 microns in size. Has a lifespan of approximately 3 years.

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.

The best service from Honest Air

A huge thank you to Matt for providing the best service when it came to the overwhelming process of choosing a purifier that was right for me.

Clean air!

Our health practitioner recommended potassium iodide air purifiers for our old house to clean up any previous mold spores. We opted to get an AirPura for each of our 3 bedrooms because they are similar to the Austin Air HealthMate Plus but smaller. They were very easy to unbox and plug in. They quietly run 24/7 and provide us cleaner air for sleeping all night. I love knowing that our air is being cleaned of dust, mold spores, off-gassing, environmental allergens and toxins here in the Ohio River Valley, drifting wildfires, etc. I have noticed much less sneezing when I climb into bed, less dog odor in our bedroom where our two dogs also sleep, less dust in the bedrooms, and less nose blowing by the kids.
