Dehumidifiers to avoid buying

The only thing these dehumidifiers will dry up is the money in your wallet.

When you need a dehumidifier, you *really* need one. Whether you're dealing with a water leak, mould, a humid summer or a soggy winter, a good dehumidifier can take care of your damp dramas. 

But a dud dehumidifier will only extract one thing: your savings. Not only can dehumidifiers be expensive to buy, they're also not cheap to run, so choosing a poor-performing model will see you losing money twice over. 

Two of the dehumidifiers in our latest test scored just 3% for water removal. Considering that the sole purpose of a dehumidifier is to remove water from the air, you might as well not bother using them at all – a fan may well do just as good a job. Or you could try a moisture-absorbing product like DampRid: we pitted DampRid against a dehumidifier to see how they compared

Priced between $99 and $219, the three worst performing products in our test fall at the cheapest end of the price range for dehumidifiers, and unfortunately we've found that cheaper models don't tend to perform as well – many of the dehumidifiers recommended by our experts cost more than $600. However, if you can stretch your budget a bit further, we have found several models under the $500 mark that perform well.

To make sure you don't waste your money, our experts have compiled a list of the dehumidifiers you definitely don't want to buy. 

hysure t8plus

High running costs: this Hysure costs more than $11 to remove 10L of water from the air.

Hysure T8PLUS

  • CHOICE Expert Rating: 37%
  • Water removal score: 3%
  • Price: $139

No, that's not a typo: this dehumidifier scored just 3% for water removal. 

It claims to remove 750mL of water from the air per day – not much compared with the best performing dehumidifiers we tested, which will remove around 10L per day. 

It'll also set you back $11.37 in running costs to remove 10L of water, which is steep compared to other dehumidifiers. 

Yes, it's cheap, but even at this price it's just not worth the money.

pursonic 15 litre clean air max

This Pursonic model was the cheapest in our test, but it was also one of the worst performing.

Pursonic 1.5 Litre Clean Air Max

  • CHOICE Expert Rating: 41%
  • Water removal score: 3%
  • Price: $99

This is the cheapest dehumidifier we've tested, so it's not hugely surprising that it was one of the worst performing – but even a cheap product should somewhat do the job, right? 

Save your money: this isn't a good deal even at this price.

It has a tiny 1.5L tank and in our test it collected even less – just 1.14L  before it decided it was full. And its claimed water removal rate is just 500mL per day. With stats like that, it's hard to know why they opted to name it the 'Max' as it's anything but.

A Kogan dud: this model isn't worth your money.


  • CHOICE Expert Rating: 48%
  • Water removal score: 40%
  • Price: $219

A water removal score of 40% is a definite improvement on the previous two machines, but when you consider that most of the dehumidifiers our experts recommend score anywhere from the high 70s all the way to 100% for this metric, it kind of puts things into perspective. 

It's not quite as terrible as its peers – and it does have a larger tank (2.25L) and claimed water removal rate (7L/day) – but it's still far from a stellar performer. 

If you can scrape together an extra $200 for a dehumidifier, you'll be able to buy one that our experts recommend that will actually do the job for you.
