The Most Energy-Efficient Air Purifier in the UK — Around 6p a Day
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 14 watts — roughly a single LED bulb — costing around 6p a day 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 IEF of 26.2 — #1 of 247 on 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 622 m³/h CADR on the 7-Fan XL while sipping ~14 W.
- ~14 W / ~6p a day — vs 50–150 W for typical HEPA purifiers

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 XL (~14 W) costs about 6p a day — roughly £21 a year — and the 5-Fan (~8 W) about 3p a day, roughly £12 a year.
What’s the most energy-efficient air purifier? By clean-air-per-watt, the Luggable XL Ultra — Energy Star Most Efficient 2026, with an IEF of 26.2, #1 of 247 on the ENERGY STAR database.
Does low power mean weak performance? No — it delivers up to 622 m³/h CADR, matching much thirstier HEPA purifiers, because the efficiency comes from fan and filter design, not from throttling airflow.
