The Best Air Purifiers Under £100 in the UK (2026)
You don't need to spend a fortune to clean the air in a bedroom or small room. Here's what you can realistically get under £100 and how to choose well on a budget.
Quick answer
Under £100 you can get a genuinely effective True HEPA purifier for a small-to-medium room or bedroom. Prioritise a real HEPA filter and the right size for the room; accept that you'll compromise on CADR, coverage, smart features and sometimes filter cost.
What you get under £100
Budget purifiers cover small rooms and bedrooms well. You'll typically get a True HEPA filter (often with a basic carbon layer), a few fan speeds and sometimes a sleep mode. What you usually won't get is the high CADR needed for large living rooms, advanced air-quality sensors, or app control - none of which are essential for a small space.
What to prioritise on a budget
- True HEPA (H13 if possible) - never compromise on the filter itself.
- Right size for the room - a budget unit in a small room beats a mid-range one that's still too small.
- Ozone-free operation.
- Affordable, available replacement filters - cheap units sometimes have pricey or hard-to-find filters, which erodes the saving.
The compromises at this price
Expect lower CADR and smaller coverage, simpler controls, and sometimes louder operation at higher speeds. Few budget models have proper sensor-driven auto modes. None of this stops a well-chosen budget purifier doing an excellent job in a bedroom or small office - just don't ask it to clean a large open-plan space.
Common mistakes to avoid
- Buying a cheap ioniser that emits ozone instead of a true HEPA purifier.
- Choosing a unit with expensive or obscure replacement filters.
- Expecting budget coverage figures to clean a large room.

Frequently asked questions
Are cheap air purifiers any good?
A well-chosen budget purifier with a True HEPA filter works very well in a bedroom or small room. The savings come from lower CADR, simpler features and smaller coverage - fine for small spaces, not for large rooms.
What should I look for in a budget air purifier?
A genuine True HEPA filter, the right size for your room, ozone-free operation, and affordable, easy-to-find replacement filters so the running cost stays low.
Can an air purifier under £100 cover a large room?
Usually not - budget units are sized for small-to-medium rooms. For a large or open-plan space you'll need a higher-CADR model or two units.
