Frequently Asked Questions

What is a CR Box or Corsi-Rosenthal Box?

A CR Box (Corsi-Rosenthal Box) is a DIY air purifier design invented by professors Richard Corsi and Jim Rosenthal. Clean Air Kits offers premium CR Box variant kits with pre-cut panels and professional components that deliver superior performance - removing 99.95% of airborne particles including dust, pollen, and viruses.

How much do Clean Air Kits CR Box kits cost?

Our premium CR Box variant kits start at £144 for fanless kits (you supply your own fans) and £204 for complete kits with high-quality fans included. This is significantly cheaper than commercial air purifiers like Dyson (£300+) while providing superior HEPA H13 filtration.

What's included in your CR Box kits?

Our kits include pre-cut MDF panels, all mounting hardware, cable ties, and detailed instructions. Complete kits (£204+) also include 5-7 high-performance Sickleflow 120 fans and power supply. Everything you need - just add your choice of HEPA filters.

Why choose Clean Air Kits over building my own CR Box?

Our premium kits use precision-cut panels and professional components for superior build quality and performance. No cutting, measuring, or sourcing parts - just simple assembly in about 30 minutes. Our kits outperform traditional DIY builds with better airflow and filtration efficiency.

Do you offer free shipping to the UK?

Yes, we offer free shipping across the UK with delivery in 2-3 business days. We also ship to all EU countries including Germany, France, Netherlands, Sweden, and more with competitive shipping rates.

How often do I need to replace the filters?
