Best overall: Winix 5500-2

Winix 5500-2 — £159.00

This is the purifier you buy when you want the air cleaned properly and you do not want to pay extra for a lifestyle object. The 8.1 score is fair: it is strong on particulate removal, better than basic HEPA boxes at handling odours, and easy to run day to day.

Why we picked it:

• The 390 m³/h CADR and 99 m² coverage rating give it enough muscle for larger bedrooms and open-plan living spaces.
• The 4-stage system is genuinely useful: the washable pre-filter catches the big stuff, the active pellet carbon filter helps with smells, and the HEPA stage targets pollen, dust and smoke.
• Auto mode with the particle sensor means it can react for you, while sleep mode drops noise to 27.4 dB and dims the lights.

The trade-off: it is functional, not elegant, and there is no remote control included. If you want app control or a cleaner-looking appliance, this will feel dated.

Buy the Winix 5500-2 if you want a dependable purifier that does the core job well.

Best upgrade: Blueair Blue Pure 211i Max

Blueair Blue Pure 211i Max — £299.99

The extra money buys you a better fit for bigger rooms, plus a more polished premium experience than the Winix. Wirecutter calls it a stellar performer for larger spaces, and that is exactly the scenario where it makes sense to spend more.

Worth it if: you want a purifier for a larger living room or open-plan flat and you care about quieter operation, better looks and smarter ownership.

Best budget pick: Levoit Vital 200S

Levoit Vital 200S — £169.99

This is the cleaner pick if you want something closer to modern expectations: app control, smart features and strong performance without paying for a top-tier flagship. HouseFresh found it competitive with the Winix 5510, and Wirecutter places it among the strongest mid-priced options.

Worth it if: you want a budget-friendly purifier that feels more current and you care about quieter everyday use more than the Winix’s old-school simplicity.

How we chose

We looked at the factors that actually matter for an air purifier: CADR, room coverage, filtration stages, odour control, noise and real-world usability. We also cross-checked current expert testing from Wirecutter, RTINGS and HouseFresh to make sure the upgrade and budget picks are real products you can still buy.

Frequently asked questions

Is the Winix 5500-2 good for allergies? Yes. The HEPA filtration and strong particle cleaning make it a solid pick for pollen, dust and other common allergy triggers.

Is £159 too much for this type of purifier? No. It is a fair price for a model that handles bigger rooms and odours properly, but if you want app control, the extra spend on a smarter model is justified.

How often do you need to change the filter? Follow the replacement indicators and the manufacturer schedule; the washable pre-filter helps extend the life of the main filters.
