The Most Energy-Efficient Air Purifier in the UK — About £2 a Year
A purifier only protects you if it’s actually running — and most people won’t leave a 50–150 W HEPA unit on around the clock because of the electricity bill. The Luggable solves that: it draws about 15 watts — roughly a single LED bulb — costing around £2 per year to run continuously. Clean air you can genuinely leave on 24/7, guilt-free.
Independently recognised
The Luggable XL Ultra is Energy Star Most Efficient 2026 certified, and was Intertek-tested at an unprecedented 24 Smoke CADR per watt — more than double the energy efficiency of the large HEPA purifiers in the Energy Star database. You get the clean-air delivery of a big HEPA unit at a fraction of the power.
How it’s this efficient
Decades of competition in PC cooling have produced fans that move a lot of air for very little power. We pair those high-static-pressure fans with a large MERV-13 filter, so the system hits 681 m³/h CADR on the 7-Fan XL while sipping ~15 W.
- ~15 W / ~£2 per year — vs 50–150 W for typical HEPA purifiers
- Energy Star Most Efficient 2026 · Intertek-tested efficiency
- MERV-13 — ~93% particle capture (pollen, dust, smoke, viruses)
- < 35 dB whisper-quiet · ships from Oxford, UK · 12-month warranty
Cheap to run and cheap to own
Unlike proprietary systems, the Luggable uses standard 3M Filtrete MERV-13 filters you can buy anywhere — no locked-in cartridge prices. Replace every 6–12 months.

Frequently asked questions
How much does it cost to run an air purifier in the UK? Most HEPA units (50–150 W) cost £30–£120+ a year if run continuously. The Luggable (~15 W) costs about £2/year.
What’s the most energy-efficient air purifier? By clean-air-per-watt, the Luggable XL Ultra — Energy Star Most Efficient 2026, ~24 smoke CADR per watt.
Does low power mean weak performance? No — it delivers up to 681 m³/h CADR, matching much thirstier HEPA purifiers, because the efficiency comes from fan and filter design, not from throttling airflow.
