CADR is the only number that matters for clean-air delivery, and it's the one comparison sites bury. Enter your room and target air changes — we show how many units of each brand it takes, the total price, and the honest metric: cost per m³/h of clean air delivered.
Pick a room type to load its target air changes, or set your own.
Our figures are rated maximum airflow (m³/h); published competitor figures are typically measured CADR, a stricter test — so the real-world gap is narrower than the raw numbers suggest. We'll provide an independently measured CADR for any unit on request. Competitor pricing is indicative from list prices; our prices are live and ex VAT.
£/m³·h = total price ÷ clean air delivered. The lower the number, the more clean air per pound — the metric that actually compares value across brands. Lowest is highlighted.
