Dyson Hot + Cool Link -The most versatile Dyson purifier

[content-egg module=Amazon template=custom/bigcart_notitle next=1]

If the Dyson Pure Cool Link was already a 2-in-1 device, the Dyson Pure Hot + Cool Link is a 3-in-1! This air freshener is designed to purify the air in your home every day of the year. In the summer, it will keep you cool with its fan. In winter, it will warm you with its thermostat control up to 37 ° C. This air purifier should ideally be placed in a space of 20m².

Three smart functions

The Dyson Hot + Cool Link air purifier is more versatile than the Dyson Pure Cool. It has three modes of use. Its fan is adjustable from an intensity of 1 to 10. Its heating is configurable and allows the user to establish their own level of comfort. Finally, its air purifier is adjustable by smartphone like the first two functions. The air is constantly monitored by the Dyson air purifier and automatically activates filtration when needed. Nevertheless, this efficiency comes at a high price. It’s clear that the Dyson Pure Hot + Cool Link air purifier is a lasting investment of excellent quality.

The same HEPA filter as on the Dyson Pure Cool Link

The Dyson Pure Hot + Cool Link air freshener is equipped with a 360 ° fiberglass HEPA filter. Its effectiveness against polluting particles reaches 99.95% according to Dyson. The lifespan of the HEPA filter is estimated at 180 days and its change costs around 60 euros. Harmful 0.1 micron microparticles like pollen can be filtered out. Dyson adds a layer of activated carbon granules to this which helps eliminate bad odors. Thus, this air freshener is ideal for people with allergies and asthma.

A very intuitive application but a weak remote control

Dyson offers an application to install on your iOS or Android smartphone. It gives you access to all important data of the air purifier. From the percentage of clean air in a room to room temperature, it allows you to keep an eye on this air freshener all the time.

The Dyson remote is functional, but it has some weaknesses. It is initially complex to understand and requires time to adapt. Its latency is quite high, which is why the smartphone remains a better option to control this air purifier.

Quiet technology

Even though the sound level can reach 64dB when the air purifier is operating at full capacity, there are several options in place to reduce the noise. First, the automatic ignition will identify the air quality and condition the fan speed according to the amount of pollutants in the room. It will reduce the power of the machine and the noise level if the air condition is good. A night mode activates when you sleep and uses the quietest programs. The display brightness is also lowered.

CHARACTERISTICS

– Filtration system: 360 ° glass fiber HEPA filter– Optimal surface area: 20 m²– Sound level: ~ 64dB– Power: 44W– Connectivity: Yes

Dyson Pure Cool Link – The best high-end air purifier

[content-egg module=Amazon template=custom/bigcart_notitle next=1]

[content-egg module=Amazon template=custom/bigcart_notitle next=1]

The Dyson Pure Cool Link Tower has performance worthy of the Dyson brand. It is quite simply the best high end air purifier on the market. This 2-in-1 device is both a fan and an air freshener. It is perfectly suited to people who are allergic and sensitive to odors. Its Air Multiplier technology allows it to cover an area of ​​27m².

An extraordinary design

The Dyson Pure Cool Link air purifier combines good material quality with an original design. It looks like an oval tower arranged on a cylinder. This is coated with a plastic which makes the air freshener lightweight. The tower can be rotated 360 ° and maintain its efficiency. According to the manufacturer, this Dyson air purifier filters the air at 99.95%.

A high-end HEPA filter

Dyson is renowned for its high quality material. This air purifier is equipped with a 360 ° fiberglass HEPA filter which is located in the cylinder. It can remove almost 100% of volatile particles in the air even those that are 0.1 microns in size. Its maintenance requires a single annual filter change with a maximum use of 12 hours per day. The HEPA filter is rolled up in a thin layer of activated carbon which filters out bad smells like tobacco. However, it is less efficient than a standard activated carbon filter. This is truly the only flaw in this Dyson Pure Cool Link air purifier.

Remote control on smartphone

Dyson offers the ability to manage the air purifier from their phone. By installing a mobile app on iOS or Android, the Dyson Pure Cool Link air purifier can be turned on and off remotely. You can also program its operating hours, fan speed, activate a night mode to reduce noise … If you don’t want to use your smartphone, you can still control the air freshener with the supplied Dyson remote control.

Quiet in standard use, noisy in intensive use

The noise of the Dyson Pure Cool Link air purifier can rise up to 63dB at full power while the quietest air fresheners do not exceed 40dB. However, if you reduce the speed of the air purifier, you will not hear it. An automatic option helps reduce noise when the air condition is optimal. The noise level will then only be 30dB, which is an excellent score.

Optimal energy consumption

The Dyson Pure Cool Link air purifier is not energy hungry. At its lowest level, it only consumes 5W. At full speed, it reaches a consumption of 40W. In standby mode, it does not exceed 0.5W. More information can be found in our Dyson Pure Cool Link article!

Alen BreatheSmart air purifier with the most HEPA filters

Alen BreatheSmart Classic Large Room Air Purifier, 1100 sqft. Big Coverage Area, True HEPA Filter for Allergies, Pollen, Dust, Dander and Fur

[content-egg module=Amazon template=custom/bigcart_notitle next=1]

Alen BreatheSmart 75i Large Room Air Purifier, Medical Grade Filtration H13 True HEPA for 1300 Sqft, 99.99% Airborne Particle Removal

[content-egg module=Amazon template=custom/bigcart_notitle next=1]

Alen is an American brand renowned for its premium products with many features and guaranteed for life. The BreatheSmart is its best design in terms of air purifier. Combining an original design and high technology, this air freshener can filter a large area of ​​102m².

Out-of-competition design

This Alen air purifier has an imposing design reminiscent of a mini fridge. With a height of 68cm and a weight of almost 10 kg, it will not go unnoticed in your home. However, its sober and elegant design makes it one of the most aesthetic purifiers on the market. Alen offers you the choice between 14 different shades.

The originality of this freshener is the placement of an air vent at the front, while others place it at the back or on the sides. Air circulation is from bottom to top. Above the air purifier is a control panel consisting of 7 buttons. They each combine a functionality such as switching on and off, speed management or activating automatic mode.

A unique combination of 4 HEPA filters

This air freshener is a 4-in-1. First, it consists of a pre-filter which ensures the removal of large particles. Then there is a unique air purification system made up of four different HEPA filters. They look like this:

– HEPA Pure: This is Alen’s standard Hepa filter. It captures 99% of polluting particles with a size of 0.3 microns such as dust and mites.– HEPA Fresh: This is a higher level HEPA filter. It reinforces the HEPA Pure filter and adds an activated carbon function which treats household odors like that of cigarettes. It is necessary for people sensitive to volatile organic compounds (VOCs).– HEPA Silver: This HEPA filter eliminates viruses and bacteria. It prevents the growth of mold spores.– HEPA OdorCell: This HEPA filter destroys odors on a molecular scale.

Remarkable efficiency

This air freshener is ideal for people who want to filter the air in large rooms. With an optimal surface area of ​​102m², the Alen BreatheSmart air purifier is one of the best in this category. You can easily filter an entire pavilion, for example. In addition, the Alen air freshener registers an air flow of 300m³ / h. It’s a bit less than a Philips AC3256 / 10 air purifier but that’s okay.

Cutting-edge technology

The Alen BreatheSmart air freshener is equipped with a smart sensor that detects the air quality in your home. If the air is contaminated, the air purifier will initiate automatic mode which will change the fan speed. For example, if the light is red, it indicates that your room has a lot of pollutants and the automatic mode will adjust the highest fan speed to process the particles faster. If the light is light blue, the minimum fan speed will be activated, which will save energy. You can manually adjust the filtration speed or program a specific time using the timer.

A perfectible noise level

The noise emitted by the Alen BreatheSmart air purifier is its first weak point. Using the lowest speed, the air freshener records a noise level of 41.5dB. It’s a fair score, but too high for low speed. For comparison, a high-end Philips air purifier emits only 30dB at minimum performance. At full throttle, the noise level rises to 56dB. It is louder than normal conversation at home.

Too high consumption

The Alen BreatheSmart air purifier shows its second weak point in energy consumption. It is quite simply one of the most energy intensive air fresheners. It uses a power of 105W. This is twice as much as a Dyson Pure Cool air purifier and four times as much as a Xiaomi air purifier.

CHARACTERISTICS

– Filtration system: Pre-filter, Pure HEPA filter, Fresh HEPA filter, Silver HEPA filter, OdorCell HEPA filter– Optimal area: 102m²– Noise level: 41.5dB ~ 56dB– Power: 105W– CADR: 300 m³ / h– Connectivity: No
