A compact HEPA purifier sized for one bedroom. It handles dust, dander and pollen, which are the things behind a blocked nose at 3am for a lot of people. It does not address the other common complaint — stale, stuffy air with rising carbon dioxide — because that is a ventilation problem and a window solves it for nothing.

The Deep Dive
Two different complaints, one wrong purchase
People say "the air in my bedroom is bad" and mean one of two unrelated things. Stale and stuffy is carbon dioxide and humidity building up in a closed room — the fix is opening a window, and it costs nothing. Itchy, blocked and sneezy is particulate — that is what a purifier removes. Buying the wrong one solves nothing and convinces you the category is a scam.
Capacity decides everything
A purifier works by cycling the room's air through a filter several times an hour. Undersize it and the air is cleaned too slowly to keep ahead of what is being generated, which produces a device that runs constantly and changes nothing. Match the rating to the room first; compare features afterwards.
The ongoing cost
Filters are consumables. Factor a replacement or two a year into what this actually costs, and remember that a purifier running on an exhausted filter is a fan with extra steps.

Key Features
True HEPA
The particles that matter
Captures the fine particulate behind overnight congestion for anyone with dust or animal allergies.
Sized for one room
Matched to a bedroom
Capacity is the specification that decides whether a purifier does anything at all.
Quiet on low
Can run all night
A purifier only helps if it is on while you sleep, which means it has to be liveable at bedtime.
App control
Schedule it
Run it during the day and on low overnight, rather than remembering to switch it on.
Frequently asked questions
Will an air purifier help me sleep?
If your problem is particles — allergies, dust, a pet in the room — it can make a real difference to overnight congestion. If your problem is stuffiness, it will not, because purifiers filter air rather than refresh it.
How do I know which problem I have?
Stuffy and warm by morning with a headache points to ventilation. Blocked nose, itchy eyes and sneezing, especially seasonally or with a pet, points to particles.
Does the size matter?
A great deal. A purifier rated for a small room in a large one cycles the air too slowly to make a difference, which is the usual reason people conclude purifiers do not work. Match it to the room before comparing anything else.
Is it quiet enough for a bedroom?
On its lower settings, generally. On maximum, any purifier is audible — though some people count that as free masking.
