Match the purifier’s coverage to the room you’ll use it in; manufacturers quote a square metre or cubic metre figure and a CADR (Clean Air Delivery Rate). For open-plan living areas choose a higher CADR and check how quickly the unit can cycle the air in a given space.
Look for a true HEPA (H13 or better) for particles such as pollen, dust and pet dander, plus an activated-carbon stage for smells, VOCs and smoke. Factor in the cost and availability of replacement filters - annual running costs can exceed the purchase price over a few years.
Check decibel figures and whether the purifier has a quiet or sleep mode if you intend to run it in a bedroom. Placement matters too: keep some clearance around intakes and, for best performance, position the unit where air can circulate rather than tucked in a corner.
Consider power consumption if you plan to run the purifier continuously - models with efficient motors and eco modes will cost less to run. Many modern units have energy-saving settings and timers to reduce bills and environmental impact.
Decide which extras matter: smart controls, air-quality sensors, auto mode, or an app with scheduling. Look for independent certifications (e.g. AHAM CADR or third‑party lab tests) and check warranty and customer support options available in the UK.
