New Dyson Pure Cool air purifiers launched

Dyson has launched two new air purifiers ready for Spring 2018 – the Pure Cool tower and desk fan. The company says that they are the most advanced air purifiers it has launched. Despite the uncanny visual similarities to Dyson’s previous air purifiers, launched in 2015, the Pure Cool tower and desk fan are packed with some really exciting and useful features.

Prices start at GBP399.99 for the desk fan and go up to a whopping GBP499.99 for the tower. This is GBP50 more than the original 2015 models. So are these Dyson air purifiers worth the money?

Find out our first impressions of the Dyson Pure Cool desk fan[1].

What’s new for Dyson’s Pure Cool air purifiers?

Dyson has seen an explosion of growth in Asia in recent times – particularly in China, the world’s largest market for air purifiers. That’s perhaps unsurprising when you consider that only 84 of 338 Chinese cities measured reached the national standard of air quality in 2016. So it makes sense that Dyson has teamed up with likes of Peking University in Beijing, as well as King’s College London, to help calibrate some of the new tech that features in these purifiers.

The new Pure Cool tower and desk fans have LCD screens that feed back in real time the pollutants that are present in your house. The Pure Cool also features a new filter – Dyson claims it has a capture rate of gas and microscopic allergens of 99.95%. The firm also says that its new Air Multiplier technology will project the clean air across your room, so it’s not just the immediate area that benefits.

Will the new Dyson Pure Cool air purifiers clean my air?

We’ll be able to answer this question once we get the test results from our lab in early summer.

We test air purifiers’ ability to extract particles of dust, smoke and pollen from the atmosphere inside our test chamber. The best air purifiers remove more than 90% of the particles we add. Poor machines manage only 44%.

The worst remove so few that we can’t officially report on the figure. We have full test results for Dyson’s previous generation of air purifiers, the Dyson Pure Cool Link TP02 and Dyson Pure Cool Link DP01. You can find out how they performed in our tough lab tests – go to Dyson air purifier reviews[2].

Why buy an air purifier?

If you suffer from dust and pollen allergies, a good air purifier can reduce the number of allergens in the air.

We all know the potentially harmful impacts of being exposed to outdoor air pollution, especially if you live in a busy city. Buying a good air purifier is one way of tackling indoor air pollution. Last spring, we investigated indoor air pollution before and after doing a range of normal household activities in three different types of houses.

We did tasks that included cleaning, using air fresheners, lighting candles and even cooking a fry-up and burning toast. In one case, we found that the particulate matter levels (PM), which can increase the risk of lung and heart disease if at persistently high levels, was increased by over 560 times. Which? members can read our full air pollution investigation[3].

You can take steps to help reduce PM levels. Use an extractor fan or cooker hood, and open your windows or any trickle vents. Vacuum regularly, preferably with a vac that sucks up dust with minimum emissions – see our Best Buy vacuum cleaners[4].

Revealed: how often people clean their kitchen appliances

The majority of Brits don’t regularly clean their home appliances, with washing machines, ovens and dishwashers likely to be the least-cleaned, a new survey by has revealed. Many of us seem to be lacking in hygiene when it comes to cleaning these products. Some 71% of the 1,015 UK adults surveyed admitted they don’t regularly clean their home appliances, with washing machines only cleaned once a year on average.

Worryingly, the survey also reveals that nearly a quarter of Brits have replaced their appliances more frequently as a result of lack of cleaning. On the lookout for a new appliance? Go to our Best Buy washing machines[1].

The least-cleaned appliances in the home

After washing machines, the survey indicates that ovens and dishwashers are the least-cleaned appliances, with the average person cleaning them just two and three times per year respectively.

Fridges and microwaves tend to be cleaned slightly more often, with the average Brit cleaning them eight and 21 times per year respectively. The survey reveals some questionable cleaning habits, but the thought of cleaning your appliances needn’t be something that fills you with fear – as our tips below show.

Clean your washing machine in four simple steps

Don’t put up with a putrid pong coming from your washing machine – follow these four easy steps:

  1. Run a regular service wash – Washing at 40?C or less is a great way to save money on energy bills and is better for the environment. But the lower temperatures mean mould and bacteria can build up, especially if you use liquid detergents, rather than washing powder.

    A service wash is a hot wash run when the machine is empty, ideally performed once a month. This will help kill the build-up of bacteria and should help to stop smells.

  2. Clean the rubber seal – Festering mould and bacteria in the rubber seal around the door hole can also be a source of smells, so cleaning it regularly can help prevent this.
  3. Wash the detergent draw and lint filter – Watch our handy videos on cleaning the detergent drawer[2] and strange noises in your washing machine[3] to help you with this bit.
  4. Leave the door open and drawer open – A simple, but effective way to let air in after your wash and help combat mouldy smells.

Read our guide on how to clean a smelly washing machine[4] for more information and to find out what to do if your machine still smells after you’ve completed all four steps.

Self-cleaning ovens

If you shy away from cleaning your oven, it may be worth buying an oven that cleans itself. Ovens with self-cleaning catalytic liners are increasingly common.

These are rough surfaces inside the oven that are designed to catch, absorb and break down food spills. When the oven is used at 200?C or higher, the food spills simply get burned away. However, some ovens only have liners at the back or on the roof of the oven and the liners don’t clean the shelves for you, so you’ll still need to use some elbow grease.

If you really hate cleaning your oven, you may want to invest in an oven with a pyrolytic cleaning function. This is a superhot cycle designed to reduce any baked-on cooking grime to ash that you can then simply wipe away. These ovens tend to be on the pricier side, but we’ve tested Best Buys ovens[5] with this technology that cost as little as GBP380.

How to clean your dishwasher

A dishwasher cleans your dishes for you, so why would you need to clean it? Well, trapped food debris, blocked spray arms and unpleasant odours – the third most common dishwasher problem reported in our own annual dishwasher reliability survey – are unfortunately all too common. But more often than not, they’re easily fixable with a minimum of effort.

The more often you clean the filter the less unpleasant it is, and running the dishwasher empty and hot every six months is an easy way to help keep your machine running smoothly.

We reveal more top tips in our how to clean a dishwasher[7] guide.

Eden Project launches eco-friendly Nespresso pods

As part of its mission to address the problem of waste plastic, the Eden Project has unveiled its own range of fully biodegradable Nespresso coffee capsules. The new capsules, which can be placed in your home composting bin, compost heap, or food recycling bin when finished, are available now in Waitrose stores and online. While they’re not the first compostable Nespresso pods we’ve seen, they are one of few to claim to fully break down in home compost waste in a matter of weeks.

The card packaging is printed with vegetable-based inks and can also be recycled, making for a guilt-free espresso experience. The Eden Project says that the coffee is ethically sourced, too. There are four flavours to choose from, all are single origin coffees:

  • Columbian – described as bright and crisp with notes of lemon, grapefruit and caramel
  • Guatemalan – delicate with notes of almond, hazelnut and chocolate
  • Costa Rican – complex with notes of toasted barley, spices and black walnut
  • Italian Espresso Decaffeinated – delicate, smooth and rich with notes of caramel, nuts and citrus

The Eden Project capsules are compatible with Nespresso coffee machines and are due to be sold at Waitrose, the Eden Project shop and on Amazon.

They cost GBP3.50 per pack of 10 at Waitrose. At 35p per pod, that’s roughly on par with Nespresso’s own capsules. Best Nespresso-compatible capsules[1] – see the top picks selected by our expert tasting panel

The rise of capsule coffee and why it matters for the environment

Capsule coffee systems such as Nespresso are extremely popular as they allow you to make quick, easy and mess-free espresso at home.

However, the pods are difficult to recycle, as they are usually a mix of plastic, aluminium, foil and coffee grounds. Nespresso has its own recycling scheme, as do some third-party Nespresso compatible pod brands. We’ve seen a number of compostable capsules launch in recent years too, but these usually need to go in your kerbside food waste recycling bin, for collection by the council, as the materials require higher temperatures and industrial recycling methods to break down.

If you don’t have the facility to recycle food waste via your local authority, or simply want a home composting method, these new capsules could be just the ticket. We haven’t tested these capsules yet, but in the meantime you can get our expert verdict on other popular pods, including some compostable versions, by checking our list of the best Nespresso-compatible capsules[2].

Other compostable Nespresso pods

Here’s a round-up of the other main compostable Nespresso-compatible options available.

Home compostable coffee pods

These are thin on the ground, but Novell and Oquendo both sell fully compostable Nespresso-compatible pods, which can go straight into your home compost bin. Novell’s pods come in two flavours – Intenso (with aromas of cereal and vanilla) and a decaf alternative.

A box of 10 capsules costs GBP3.30. Oquendo’s Natura pods come in five variations and cost GBP2.99 for 10 capsules, excluding any postage costs.

Compostable Nespresso pods (via local authority)

Dualit NX pods

Dualit makes a range of pods that are compatible with both Dualit and Nespresso coffee machines, including a selection that are compostable via your local authority food waste collection. You can try Dualit’s ‘bold yet creamy espresso’ Sumatra Mandheling beans, or the Indian Monsoon ‘dark roasted espresso with a spicy finish’.

At the time of writing, a pack of 60 capsules costs GBP12, which at 20p per capsule is cheap compared to Nespresso. See how Dualit’s Nespresso-compatible coffee machine fared in our coffee machine tests – read the full Dualit Classic review[5].

Percol compostable pods

Percol has a selection of pods that are fully compostable via your local authority. Made of plant-based materials, they are said to completely break down within 12 weeks.

You’ll find an Americano lungo, Organic Ethiopia espresso and Supremo ristretto in the range. You can see what our coffee experts made of the Ethiopia espresso in our full Nespresso taste test results[6].

Colonna compostable pods

Colonna’s plastic Nespresso pods are recyclable via your local authority. However, it’s worth noting that before you throw away a used capsule, you’ll have to peel off the foil lid and clean out the coffee grounds, which is a time-consuming job.

The brand has produced a limited run of compostable capsules – Las Galeras Columbian espresso and Wegida Blue Lot Ethiopian espresso – which, like the others above, can be recycled via your local authority food waste scheme.

Coffee pod recycling schemes

While the big-name coffee capsule brands have yet to bring out compostable pods, most have their own recycling schemes to tackle the used pods piling up on your worktop. Here’s a look at some of the better-known options:

  • Nespresso[7] you can get your used pods picked up when your new ones are delivered by Nespresso. Alternatively, you order recycling bags on the Nespresso website and send the pods back via CollectPlus.
  • Tassimo[8]The coffee brand has partnered up with TerraCycle to create a free recycling service for used Tassimo T-DISCs, L’OR capsules and Kenco Eco Refill packs.

    Head to to find your nearest drop-off point.

  • Starbucks – You can get rid of your used Starbucks capsules by requesting a recycling bag in-store.

    Fill up the bag, print a recycling programme shipping label from the website and return to your nearest postal drop-off location.
