Air purifier for sinus problems and congestion
In one line: if your congestion is driven by airborne allergens — dust-mite debris, pet dander, pollen or mould spores — a HEPA purifier that removes them can genuinely ease a blocked, irritated nose, especially overnight. It won't help congestion from colds, infection or non-allergic causes.
The allergen link
A lot of chronic stuffiness and sinus irritation is an allergic response to what's floating in the air. Remove more of those particles and the trigger drops — which is why people with dust or pet allergies often wake less congested with a bedroom purifier running. The relevant allergens (dander, dust-mite debris, pollen, mould spores) are all particles a HEPA/MERV-13 filter captures; see the allergies guide.
Where to run it
The bedroom first — hours of continuous, still breathing overnight is where reducing allergens pays off most for congestion. Size it for a good air-change rate and run it quiet and continuous.
What it won't fix — and a dry-air note
A purifier does nothing for congestion caused by a cold, sinus infection or structural issues — those need other care. Also, purifiers don't add or remove moisture, and very dry indoor air (winter heating) can itself irritate sinuses; if dryness is the issue, a humidifier is the tool, not a purifier (see do air purifiers dry out the air?). And avoid ozone-emitting devices, which irritate airways.

FAQ
Can an air purifier help a blocked nose? If the cause is airborne allergens, yes — removing them can reduce congestion, particularly overnight. It won't help a cold or infection.
Does an air purifier help or hurt dry sinuses? It doesn't change humidity. If dry air is irritating your sinuses, use a humidifier; the purifier just handles particles.
