Check the clean air delivery rate (CADR) and the manufacturer’s recommended room size so the unit can cope with your living room or bedroom. Tower purifiers vary widely - choose one rated for at least the floor area (m²) where you’ll use it most, and allow headroom if you have high ceilings or open-plan spaces.
Look for a true HEPA (H13 or H14) filter for fine particles (PM2.5, pollen, dust) and an activated carbon stage for gases, cooking odours and VOCs. If you need extra protection, check for additional stages such as pre-filters, photocatalytic or specialised gas filters, but be wary of technologies that produce ozone.
Tower purifiers are often used in bedrooms, so compare decibel ratings at low and high speeds and whether the unit has a quiet or sleep mode. Lower noise usually means lower airflow, so balance the sound level you can tolerate with the CADR you need.
Decide if you want Wi‑Fi, app control, voice assistant compatibility (Alexa/Google), and useful sensors such as automatic air-quality adjustment and PM2.5 displays. Also consider the unit’s footprint and height - tower designs are space-saving but need clearance for airflow and shouldn’t be tucked straight against a wall.
Estimate the ongoing cost of replacement filters, typically every 6–12 months depending on use, and the energy consumption (look for power ratings and eco modes). Factor in warranty length and availability of genuine replacement filters in the UK to avoid inflated maintenance costs.
