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.
What Our Customers Say
Trusted by thousands of happy customers
As a school administrator, maintaining good air quality is critical. The Luggable unit immediately improved our ACH levels and reduced illness spread. Delivery within the EU was fast and hassle-free.
We work in a clinic with vulnerable patients, and having a portable filtration system that genuinely improves air circulation has made a noticeable difference. Excellent build quality and shipped quickly from the UK/EU.
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.
We purchased the Luggable for our shared workspace after recurring flu outbreaks. Air feels noticeably cleaner, and staff sickness has dropped. EU shipping was extremely quick.
Brilliant filtration performance. You can feel the difference in minutes, especially in older buildings with low ventilation. Very reassuring that everything ships directly from the UK/EU.
I run a childcare centre where reducing airborne transmission is essential. This system significantly improved our room’s ACH and the air feels noticeably fresher. Fast European delivery was a huge plus.

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.
Our Features
Large Capacity
Choose clean air delivery rates up to 500 cfm comparable to the largest HEPA purifiers and C-R cubes. Lowers viral concentrations substantially within classrooms and dining rooms.
Quiet on Full
Clean Air Kits produce 5-10x less noise than HEPA purifiers at max capacity.
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!
