Not all air purifiers are equal — and the price tag is rarely a reliable guide to performance. This comparison uses three independently verifiable metrics: CADR (Clean Air Delivery Rate, how fast the unit cleans a room), noise level (in decibels at full speed), and 5-year total cost of ownership (purchase price plus filter replacements plus energy costs).

Commercial purifier brands typically design around proprietary filter lock-in. A Dyson or Philips unit may cost €300–500 upfront, but replacement filters at €50–120 each — required every 6–12 months — mean 5-year costs of €700–1,200. Our Corsi-Rosenthal kits use standard MERV 13–16 filters available from any hardware supplier for €15–30 each, replacing annually, for a 5-year filter cost of €15–30 total.

The table below compares our Blanc and Obsidian kits against the three most common commercial brands in the EU market. All CADR figures for our kits are independently verified by Intertek. Commercial brand figures are drawn from manufacturer specifications and independent third-party reviews (HouseFresh, Consumer Reports, Stiftung Warentest).
