Filtration ROI: How to Justify Your Kitchen Extract Upgrade

Upgrading filtration isn’t just a hygiene exercise — it’s a financial decision. When you move to ESP + carbon (and ozone where needed), " "you can reduce energy, cleaning and complaint‑related downtime. Here’s a simple way to quantify the return.

Where the savings come from

Energy : ESP has inherently low ΔP compared with dense mechanical filters; the fan does less work. Cleaning : Effective particulate control keeps ducts cleaner for longer under TR19 regimes. Complaints/downtime : Better odour control reduces enforcement risk and lost trading hours.

A quick ROI model

Baseline current costs — fan energy (kWh), duct cleaning frequency, odour call‑outs, emergency visits. Model new ΔP and maintenance intervals with ESP + carbon (+ ozone if required). Add a reasonable risk reduction value for fewer complaints and disruptions.

Making the brief watertight

State the required performance outcomes (capture efficiency, odour at boundary) rather than brand names. Include commissioning evidence: airflow, ΔP, interlocks, leakage checks. Attach a maintenance plan and logs to keep results steady over time.

Tell the full story

Pair the numbers with practical benefits: cleaner canopies and ducts, happier neighbours, and fewer Friday‑night emergencies. "
