Look out from the window of your house. If you live in an Indian city, you are likely to stare at the misty landscape shrouded in pollution.

Due to the sudden increase in pollution levels in northern India and the decline in air quality, now may be the right time to consider the need for air purification in the home.

Apart from wearing a mask, there is nothing that can be done outdoors. But in your home, you can probably control the air you breathe.

Air purifiers provide some respite, and they are no more advanced than Dyson's latest update.

The timing is just right, because Dyson's new purifiers-Dyson Purifier Cool and Dyson Purifier Hot Cool-are replacing the models of the same name in the series. Especially the latter is a unique proposition, because it is one of the rare cases where your air purifier doubles as a room heater.

In addition to minor changes, the biggest upgrade is the new HEPA, or high efficiency particulate air filter. Dyson upgraded it to the HEPA H13 standard, which is the highest standard for household indoor air purifiers.

Dyson Purifier Cool (model TP07) sells for approximately Rs 39,105, while Dyson Purifier Hot Cool (model HP07) retails for approximately ₹47,515. They all have a combination of black and nickel or white and silver.

You pay a certain premium with these price tags, but these improvements add a higher level of purification precision to the mix of style and substance.

By the way, HEPA filter upgrades are common for Dyson Purifier Cool and Dyson Purifier Hot Cool, which makes the new purifier series more powerful in capturing visible and invisible rogue pollution particles.

The implementation is that the filter itself remains completely sealed. In fact, the lid of the filter chamber is locked with a high-pressure seal, as is the chamber where the filter is located. This significantly reduces the chance of any impurities escaping and remixing into the room air.

This is not the case with general air purifiers. It has a simple cover between you and the filter, most of which are fragile and usually do not have a tight lock.

The design of Dyson Purifier Cool and Dyson Purifier Hot Cool is basically the same as before, with only minimal visual adjustments to make you notice.

The base of the machine is more obvious, especially the combination of black and nickel. This also means that the clean airflow options include airflow directly towards you or towards the front of the air purifier (that is, 350 degree oscillation options), or a diffusion mode where the air is discharged from the vents placed on the air purifier. Back.

This is especially suitable for the Dyson Purifier Cool variant in winter, when you don't want the cool ambient air to hit you quickly. This option is also available in hot and cold Dyson purifiers, but not available when the heating mode is enabled.

The new filter can also capture particles as small as 0.1 microns, which is 100 times thinner than the width of a human hair. These particles can not only enter our lungs, but also enter the blood. Most indoor air purifier filters can capture particles 0.3 microns or larger.

The filter upgrade, including the activated carbon layer, differs in the time it takes for the AQI of the contaminated room to drop to a cleaner reading. These two can do this faster than their predecessors.

We verified this with a separate air quality monitor. Dyson Purifier Cool and Dyson Purifier Hot Cool can also maintain air quality well, even in active rooms such as living rooms.

Having said that, during most of the time in automatic mode, this will boost to higher fan speeds and is also very sensitive to the smallest changes in air quality. Dyson Purifier Cool and Dyson Purifier Hot Cool have been redesigned to reduce air turbulence when the clean air is exhausted from the vent, making it slightly lower noise than before, and the improvement is most obvious when the fan speed is higher than 5.

If you are considering the versatility of Dyson Purifier Hot Cool, it also has similar air purification capabilities to Dyson Purifier Cool. Like its predecessor, it has a positive temperature coefficient (PTC) heating element placed vertically at both ends of the loop, where clean air flows out. These are heated before the air comes out of the vent.

According to our experience, this is very effective for heating rooms. Although we have not had the opportunity to use it on a suitable winter day, it seems to be able to cope with extremely cold temperatures well.

In terms of continuity, the smart Dyson Link application is still one of the best applications in the smart air purifier industry, as is the attention to detail. For example, the display on the purifier allows you to switch large amounts of information and connect via magnetic To the stylish remote control on the top of the purifier, and the ability to control these remotes via voice commands from Amazon Alexa or Google Assistant, these remotes are ready on smart speakers or mobile phones.

Compared with most other companies, Dyson tests air purifiers in a different way. Although competitors use a method called CADR or Clean Air Delivery Rate to give their purifiers a power ranking, Dyson has a different test called Polar.

The CADR test is carried out in a room of approximately 11.8 square meters (127 square feet). The purifier is placed in the middle of the room. A fan is used to circulate the air around the room. There is only one sensor to measure air quality.

There are two problems. One, we will not place an air purifier in the middle of the living room or bedroom. Secondly, there is no fan to help air circulation in winter.

Dyson's POLAR is completed in a larger room of 27 square meters (290 square feet). There is no fan and the purifier is placed in the corner of the room, just like in the home, with additional sensors in eight different places to cover the room. The farthest corner of the city.

At first glance, they don’t look very different, and even a consistent naming scheme will not tell you if there are new products. But Dyson Purifier Cool and Dyson Purifier Hot Cool have undoubtedly improved their smart quotient through the latest update.

You did pay a premium, but the money you spent will definitely be rewarded-distinctive design in the home air purifier space, high-quality HEPA H13 filters, the best smartphone companion app in the industry, and deep clean air The smallest particles.

Although compared to some other larger air purifiers, these purifiers take longer to reduce PM 2.5 readings, but the Dyson Purifier Cool and Dyson Purifier Hot Cool clean deeper and better, which is more difficult for the invisible It is a good thing for health hazards.
