Key takeaways
- A true HEPA (H13) filter is the part that matters for pollen, dust and pet dander. Everything else is a bonus.
- Match the purifier to your room size. A bedroom unit will struggle in an open-plan living room.
- For hay fever, run it on a low setting overnight with the bedroom door and windows shut.
- Budget bedroom models start around £40. A capable large-room unit is usually £100 to £130.
Grass pollen is still high across much of the UK this July, and the run of hot, still days keeps it hanging around indoors once you open the windows. That’s pushed air purifiers back up the shopping lists, especially for anyone with hay fever, asthma or a shedding pet. The good news is you don’t need to spend a fortune. A decent HEPA unit for a bedroom now costs less than a night out, and the step up to a large-room model is smaller than it used to be.
We’ve pulled together six air purifiers you can buy on Amazon UK right now, each one picked for a different job: bedrooms, big open rooms, tight budgets, allergies and small spaces like a desk or nursery. Prices move around, so treat the figures below as a guide rather than a promise.
How we picked these
We started with the filter. Anything worth buying uses a true HEPA filter, ideally rated H13, which traps 99.97% of particles down to 0.3 microns. That covers pollen, dust mite debris, pet dander and most smoke. We were wary of cheap units that only list a “HEPA-type” or “HEPA-like” filter, as those don’t have to meet the same standard.
After that we looked at room coverage against the maker’s stated figure, noise on the lowest setting (important if it’s running in a bedroom), the cost and availability of replacement filters, and the real-world review score on Amazon. We leaned towards models with a good number of reviews rather than a handful of glowing ones. Smart features like app control and auto mode are nice to have, but we didn’t let them override the basics.

The air purifiers
Levoit Core 200S
Best for bedroomsLevoit is the name that keeps coming up for good reason. The Core 200S is quiet on its lowest setting, small enough to sit on a bedside table, and the app lets you set a schedule so it powers down once you’re asleep. The three-stage filter handles the usual pollen and dust without any fuss.
The catch: there’s no built-in air quality sensor, so it won’t speed up on its own when the air gets worse. You set the speed yourself.

Check price on Amazon →Levoit HEPA Air Purifier (bedroom)
Best budget buyIf you just want clean air in one room without spending much, this is the one. It uses the same three-stage HEPA setup as the pricier Levoits, covers a decent bedroom, and there’s a fragrance sponge if you like a light scent. For roughly £40 it’s hard to argue with.
The catch: no smart features and no display, so you’re working with a simple dial. It also runs louder on its top speed than the quieter models here.

Check price on Amazon →GoveeLife Smart Air Purifier
Best for large roomsFor an open-plan lounge or a big kitchen-diner, you want more airflow, and this GoveeLife is rated for up to 97m². It has a PM2.5 sensor that shows the current air quality and ramps the fan up when it climbs, plus app control if you want to run it from the sofa. It’s the one to reach for when a bedroom-sized unit just can’t keep up.
The catch: it’s physically bigger than the rest, so it needs floor space. And to actually clean a room that large you’ll hear it working on the higher speeds.
PM2.5 sensor · auto mode · around £130
Check price on Amazon →DREO TurboPure Air Purifier
Best for allergies and hay feverThis one has the highest review score of the group and a strong airflow figure for its size, which is what you want when you’re trying to clear pollen from the air fast. The three-in-one HEPA filter deals with fine particles, and there’s a proper quiet sleep mode for overnight running, when most hay fever sufferers feel the difference.
The catch: DREO is a less familiar name than Levoit or Blueair, so replacement filters can be slightly harder to find on the high street. Order them online and you’re fine.
Rated for rooms up to 80m² · sleep mode · around £100
Check price on Amazon →Blueair Blue Pure 511
Best trusted-brand pickBlueair is a specialist that only makes air purifiers, and it shows. The Blue Pure 511 uses the brand’s HEPASilent system, which pairs a filter with a light electrostatic charge to stay quiet while still catching fine particles. It’s a clean, simple design with a washable fabric pre-filter that comes in different colours, so it doesn’t look like a bin in the corner.
The catch: it’s a one-button unit with no sensor or app, which feels basic next to the smart models. You’re paying for the filtration and the build, not the gadgets.
Rated for rooms up to 38m² · washable pre-filter · around £89
Check price on Amazon →Homedics WhisperPure Mini
Best for desks and small spacesNot every space needs a full-size purifier. This little Homedics is built for a desk, a nursery or even a car, and it’s quiet enough that you’ll forget it’s on. For the money it’s a tidy way to clean the air in the spot where you actually spend your time, rather than trying to treat a whole room.
The catch: it uses a HEPA-type filter rather than a certified H13, and it’s only meant for small areas. Don’t expect it to clear a living room.
Compact and portable · very quiet · around £40

Do air purifiers actually help with hay fever?
They can help, as long as you use one with a true HEPA filter and run it in a room with the windows shut. It won’t stop pollen reaching you outdoors, but it can lower the amount floating around your bedroom, which many people find makes nights more comfortable during the season.
What size air purifier do I need?
Check the maker’s stated room coverage in square metres and match it to the room you’ll use it in. If anything, size up a little, since a purifier rated for a bigger room can clean a smaller one faster and more quietly on a lower speed.
How often do you replace the filter?
Most HEPA filters last six to twelve months depending on use and how dusty your home is. Factor the replacement cost into your budget, because a cheap purifier with pricey filters can work out dearer over time.
Should I leave an air purifier on all the time?
You can, and many run on a low setting around the clock. Modern units use little power on their lower speeds, and keeping it on steadily is more effective than blasting it for an hour once a day.
