Industry Leading Efficiencies
EnergyStar rated our PC Fan Filters 2 to 9 X more energy efficient than large HEPAs with equivalent clean air delivery -- save hundreds £££ / year in electricity and filter replacements!
- ✓ Upfront cost + 2 filter changes + 3 year @£0.22/kWh
- ✓ 40 CADR cfm/occupant
- ✓ Most efficient speed < 50dB
- ✓ Energy Star's Most Efficient 2025 Award
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!

Safety Feature Image
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.
Scientifically Optimized
We tested dozens of fan & filter combos to create unprecedented efficiency in: Price, Energy, Noise.

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. Replace every 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.
Contagion Risk decays exponentially with faster air cleaning
March 2022: Study of 10,441 Italian Classrooms with varying mechanical ventilation up to 6 ACH.
Large Capacity
Choose clean air delivery rates up to 500 cfm -- comparable to the largest HEPA purifiers and C-R cubes.
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 -- people turn them down. We have just one speed: silent full blast!
Unprecedented Energy Efficiency
Our fan banks use 6-16W -- comparable to a LED bulb!

From the Indoor Air Quality Experts
"I'm now a convert. PC fans from now on. I built two PC fan CR boxes and I'm addicted. Using PC fans might be the most important innovation to portable air cleaners since the invention of the original CR box. These are unbelievably quiet."
Joey Fox
HVAC Engineer, Indoor Air Quality Chair, Ontario Society of Professional Engineers
"Standalone HEPAs or Corsi-Rosenthal boxes are a quick way to lower the risk of inhaling SARS-CoV-2 virus. Filtering the virus out of the air reduces the chance of inhaling it---simple logic."
Kim Prather, PhD
Distinguished Professor, UCSD, Director NSF Center for Aerosol Impacts
"3M tested the Corsi-Rosenthal Box with the same rigor it applies to its Filtrete brand and found the C-R Box performs exceptionally well in its ability to capture unwanted airborne particles, including viruses."
