360° glass HEPA and activated carbon filter Sealed HEPA filter made from borosilicate microfibres, pleated hundreds of times, to capture 99.95% of ultrafine particles with activated carbon filter to remove gases and odours.
Whole-machine HEPA H134 filtration system captures dust, pollen bacteria and ultrafine particles the size of 0.1 microns. An activated carbon filter removes gases and odours which emit from common household items, cleaning sprays and cooking appliances.
The fact of the matter is, because air purifiers work to remove harmful air contaminants within a space, they can be effective smell removers, but it's not their main function.
So an air purifier is a great means of removing foul smells from a room. Within a few hours, you will see that the dander, mites, pollen and other airborne particles have been removed, leaving fresh air for you.
Several common household items (most notably baking soda and white vinegar) contain powerful properties that eliminate smells without the use of chemicals. But less-commonly known products like coffee and vodka can do wonders when it comes to eliminating, not simply covering, bad smells.
Some Dyson air purifiers have an “Auto” setting. It detects the number of contaminants and dust in the air and turns on automatically when necessary. If yours doesn't have an auto setting, you can run it between 12 and 24 hours. The more often you run your air purifier, the better it'll do at cleaning your air.
The fan can clean the air in a room in 30 to 60 minutes or monitor air quality to automatically bring it back to safer levels when it degrades. Company founder James Dyson said: “We think it is polluted outside of our homes, but the air inside can be far worse.
Bottom lineThe Dyson Pure Cool HEPA Air Purifier and Fan features HEPA and activated carbon filters to trap VOCs, allergens, mould, dust, bacteria and other particulates as small as 0.3 microns.
The best place to put an air purifier is somewhere in your breathing zone. The closer the unit is to your head, the shorter distance clean air has to travel before it reaches you. In the bedroom, this usually translates to putting the air purifier on a nightstand or small table close to the bed.
Air purifier placement works best when positioned 3-5 feet off the ground. At this height, they can take advantage of air flow in the room. If you have a sturdy table, placing your air purifier on top of it will put it into this ideal range and help maximize its effectiveness.
The device will work most efficiently if you place it in the central part of the room and at a close distance from windows, because it is through them that dirt mainly penetrates. If you want to use the device in the bedroom, it is best to place the air purifier between the window and the bed.
In our experience, the Dyson air purifier is a very energy-efficient device. Thanks to the latest technology, the air purifier consumes correspondingly little electricity at higher power levels.
Air purifiers assist in eliminating household dust by helping clean the air at home. These machines are engineered with technology that traps dust before it settles on your furniture and floors.
Our verdict:
Air purifiers contribute less than 1% to household energy consumption. That's only about 12% of the energy harnessed to run a fridge. You can expect to pay around $22 annually to power an air purifier, with an average daily consumption of 15W.
Even with a window open, air purifiers can work decently and still meaningfully reduce particulate air pollution in the home – by 60% in 20 minutes in our tests.
Dyson vacuums are designed for efficiency and easy maintenance. One important part of maintaining your Dyson vacuum is knowing when to empty the dustbin. The dustbin should be emptied after every use, or at least once a week. If you have pets or live in a dusty environment, you may need to empty the dustbin more often.
Dyson purifier fans are engineered to provide powerful, personal cooling. They're not designed to lower the temperature of a whole room like an air conditioner does.
Dyson fans and purifiers have no energy-hungry cooling elements like air conditioning units, they aren't designed to lower the room temperature. Our products cool you, not the room. They work by circulating the ambient air in the room.
360° sealed filtration – removes gases and particulates. The fully-sealed filter system combines an activated Carbon filter to remove gases, and a Glass HEPA filter that captures 99.97% of microscopic allergens and pollutants as small as 0.3 microns.
Placing an air purifier in your bedroom can allow you to breathe clean air for hours at a time, which you may not be able to experience during the day. However, to get the most benefit to your indoor air quality, you should make sure that your air purifier is in an ideal spot, like your nightstand, while you sleep.
Rule 1: Keep It in the Breathing Zone
However, with many small purifiers, like those designed to be put in bedrooms, it is beneficial to try and have them near the bed. This will ensure you breathe fresh air while you sleep, instead of air purified a while ago and have had time to pick up pollutants.
Elevating the air purifier off the ground not only prevents a tripping hazard, but increases the floor-to-ceiling cleaning efficiency by trapping airborne particles near the ceiling faster.
With long-life filters that are quick and easy to replace, Dyson purifiers capture 99.95% of ultrafine particles such as allergens and pollutants from the air.
We suggest you clean your filter at least once a month to keep your machine running at maximum efficiency.
