Hayfever and allergies are the absolute pits: all that scratching and sneezing can be relentless and just plain unpleasant.
Whether your allergies only flare when the seasons change or you're suffering year-round, an air purifier can help dial down your discomfort.
But they're not cheap: some cost well over $1000, which is a lot when you're already spending a fortune on antihistamines and inhalers.

However, the price can be worth it if they do the job.
But spending more won't necessarily give you better relief – some of the most expensive machines are disappointingly ineffective, while some of the more affordable models banish allergens better than products costing far more.
So how can you make sure you're spending your hard-earned money on a model that justifies the price tag?
CHOICE's appliance experts tested 39 air purifiers in our labs, assessing their ability to remove dust, smoke and volatile organic compounds (VOCs) from the air.
The best air purifiers banish more than 90% of the particles; others remove significantly less (but they can extract quite a lot of dollars from your wallet).

Here's how we tell which models are the best at removing dust and pollen. Plus, which models aren't worth your money.
And exclusively for CHOICE members, we'll reveal exactly which models are the best at removing these allergens from the air, plus how well they remove other pollutants.
If you just want to get straight to the best products, you can jump to the results now.
How to tell which air purifiers are best at removing pollen
Our testing measures how much dust, smoke and VOCs each air purifier removes from the air. But what if you specifically need something to minimise the pollen count inside your home?
"Dust and pollen particles come in a wide range of sizes, but they are broadly similar, so if an air purifier is good at removing dust from the air, then it'll also work well for pollen," says CHOICE appliance expert Chris Barnes.

But he also issues a word of warning.
"If you or someone in your household is asthmatic, steer clear of air purifiers that use ozone technology."
"They generate ozone, which causes breathing irritation. Ionic purifiers can also produce ozone, so we recommend avoiding them too."

The importance of air purifier filters
The best filter type for pollen and dust
"HEPA filters are the best type for removing most airborne pollutants, including pollen and dust," Chris says.
"Fortunately, most air purifiers come with HEPA filters, but make sure you check that the purifier has one before you buy, and also check the price and availability of replacement filters."
Factoring in replacement filter costs
To make sure your air purifier is as effective as possible, you need to keep the filters in good working order.
Filter costs can add up quickly. Depending on the air purifier and the type of filters it uses, it could cost you more than $200 a year in replacement filters.
You can wash and reuse pre-filters and carbon filters, which will extend their life so you don't need to buy them as frequently.
Generally, HEPA filters aren't washable so you'll have to replace them from time to time. You can extend their life a little by gently brushing or vacuuming the filter surface to remove dust.

Filter design matters, too: some have separate pre-filters, carbon filters and HEPA filters so you'll only need to buy each component as it needs replacing.
Others have an all-in-one filter that you'll have to replace each time, even if the pre-filters and carbon filters still have life left in them.
If you need to run the air purifier every day, factor the cost of filters in when you're researching what to buy. A cheap air purifier might seem like value for money, but if you're spending a fortune on filters then it's not such a good deal.
Our detailed review not only shows you the best air purifiers from our tests, but also how much replacement filters cost and how much you can expect to pay for filters each year.
Dyson: Disappointing dust removal.
Should you buy a Dyson air purifier?
Surely a company that spends as much on research and development as Dyson should totally nail the air purifier thing, right?
Sadly not.
We tested three Dyson air purifiers and none of them did much to remove dust from the air, despite their large price tags and brand pedigree.
And even though the two most expensive have "formaldehyde" in their names, they actually aren't especially good at removing VOCs from the air.

In fact, none of the three Dyson air purifiers we tested performed particularly well overall in our testing, with the most expensive of all – the Dyson Big+Quiet Formaldehyde BP03 – only managing a disappointing CHOICE Expert Rating of 63%.
But five of the air purifiers recommended by our experts cost the same as or less than even the cheapest Dyson, ranging in price from $549 to $999.
A CHOICE membership could save you from spending too much on a fancy Dyson air purifier that doesn't do a good job.

Let's do the maths:
Instead of buying a $1599 Dyson, you could take out a CHOICE membership for $83.95, buy a cheaper and more effective air purifier recommended by CHOICE experts and come out $966 ahead – that's nothing to be sneezed at!
Plus you'd have access to more than 200 other reviews to help you buy better for all your other purchases.

Air purifiers to avoid if you have dust and pollen allergies
These air purifiers won't do much to remove dust and pollen from the air. Some of them are among the cheapest purifiers we tested, but others are at the upper end of the price scale.
Whether you buy the cheapest or most expensive of these, you'll have to spend even more money on antihistamines because these won't do much to help your allergies.
