I have been using your air purifier for two months now, and it is amazing. I have three other air purifiers, and none of them are even close to being as quiet as this one. They are all louder and create too much noise for a family celebration or a team meeting. Your device is the only one that can be practically placed in the room without disturbing anyone. It also looks good and fits into almost any room. The power supply via USB with a power bank works very well. I am very happy and constantly recommend it!

Inzwischen habe ich euren Luftfilter seit zwei Monaten im Einsatz und er ist großartig. Ich habe noch drei andere Luftfilter, keiner davon ist auch nur annähernd so leise wie dieser hier. Die sind alle lauter und machen zu viel Lärm für eine Familienfeier oder ein Team-Meeting. Euer Gerät ist das Einzige, was man sinnvoll mit in den Raum stellen kann, ohne dass es jemanden stört. Noch dazu sieht es gut aus, passt in fast jeden Raum rein. Die Stromversorgung über USB mit einem Powerpack funktioniert auch sehr gut. Ich bin sehr glücklich und empfehle den ständig weiter!

For most of the 20th century, medicine focused on pathogen transmission via water, hands & surface contact. Recent research has triggered a paradigm shift as aerosol scientists prove most remaining modern diseases such as flu, colds, RSV, MERS, measles COVID, and even strep A (scarlet fever) are primarily airborne.

Unintuitively Quiet

It's dead simple. CleanAirKits deliver top-end portable HEPA cleaning rates and they're QUIET. At that performance level, HEPA are not quiet -- people turn them down or turn them off. And we need them to be on and high-performing to passively remove covid, allergens and pollutants.The exceptionally large, unencumbered filtration area provided by dual micro pleated 3M Filtretes, and our diffuse banks of silent pressure fans make this possible. Delivering 200-500 cubic feet per minute of clean air means the boxes filter 1000-2000 faster than an adult human breathes!

Always On Safety

Since a Clean Air Kit is not loud and power hungry like most HEPA purifiers, it can always be running. And if it's always running, it's always adding a layer of protection for you and your family from smoke, pollen & airborne transmission of viruses like Colds, Flu, Measles, Strep, RSV, and Covid.

This corresponds to the pandemic HVAC best practice of continuously running furnace fan circulation with MERV13 or MERV14 filtration.

As someone sensitive to airborne irritants, this purifier was a game changer. ACH nearly doubled in my home office. Loved that it arrived from within Europe no delays or customs fees.

  • Scientifically Optimized

    We tested dozens of fan & filter combos to create unprecedented efficiency in: Price, Energy, Noise. Want a quick sizing rule for meeting ASHRAE 241 Control of Infectious Aerosols in homes & classrooms?
    One PC fan per room occupant

  • 3M Virus + Allergen Filters

    In EPA tests, a MERV13 CR Box drew down 97% of bio-aerosols in 30 minutes and 99.4% in 60 for a 3000 cb ft chamber. 3M Filtrete have the highest airflow amongst MERV13 brands, enabling a compact design with 1" thick filters. Replace with Filtrete 1900 or 2200 @ 6-12 months

  • Silent Pressure Fans

    Not all fans can pull thru MERV13. We identified the best value "High Static Pressure" fans from popular gaming PC vendors like CoolerMaster

  • Easy Slip-In Filter Changes

    Foam weatherseal and pre-tensioner bungees keep filters snug. Guards slide off & filters slide out and back in for replacement every 6-12 months.

One Speed Design

Speed controls defeat the efficacy of most HEPAs -- people turn them down to quiet where air cleaning slows. We have just one speed: silent full blast!

Unprecedented Energy Efficiency

Decades of competition has driven amazing silence + efficiency in PC fans. Our fan banks use 6-16W -- comparable to a LED bulb!
