CADR and filter price beat the box photo
An air purifier is a fan plus a true HEPA filter. If the replacement filter is discontinued or costs more than a new unit each year, you bought a gadget. Levoit Core 300 is the bedroom default (quiet, cheap filters). Core 400S and Coway Airmega make sense when the room is actually a living room. Blueair wins if noise and looks are the constraint. Skip ionisers and ozone as a cleaning method.
Size the room you sleep in
CADR is measured in a test chamber. Buy for the bedroom or the living room you will run 8 hours, not the open-plan m² on the box. A Core 300 in a large lounge just moves the same air slowly. Philips and Winix sit in the “known filters in three years” camp with Coway.
Filters are the product
| Job | Start here | Watch |
|---|---|---|
| Bedroom, night noise | Levoit Core 300 | Don’t “make do” in a lounge |
| Larger room + app | Levoit Core 400S | Filter pack cost |
| Living room, known service | Coway Airmega | Footprint |
| Quiet design | Blueair | Filter availability |
| Allergy, established UK SKU | Philips / Winix | Match the exact filter code |
Keep a spare HEPA in the cupboard so you never run the motor on a clogged filter. Vacuum the pre-filter monthly.
Five mistakes
- Ioniser instead of HEPA.
- Undersizing so you can hide it on a shelf.
- Ignoring filter SKUs before checkout.
- Auto mode in a sealed room as if CADR were magic.
- Scented filters — you wanted particles out, not perfume in.
Dig deeper
- Vacuums — stirring dust then purifying it is backwards
- Dehumidifiers — damp is a different job
The bottom line
True HEPA, a published night dB, and filters still sold in year three. Core 300 for most bedrooms; step up CADR when the room is genuinely larger; skip anything that “charges the air” instead of trapping it.
