Ikea Starkvind: the design air purifier

If there is one brand that seeks to stand out on this market, it is the Swedish Ikea. In this case, the furniture giant has logically sought to combine technology and design.

After a first version of purifier named Förnuftig, Ikea reiterates the experience with a new series, the Starkvind. There are actually two Starkvind models: one is offered alone, the other is integrated into a small extra table. The idea of ​​hiding this type of device in a piece of furniture is interesting if you want it to be more discreet, prettier, and benefits from an additional function as a table. This is undoubtedly the best choice if you want to hide the device as much as possible in your decor.

Sold without the table system, the Starkvind is then found vertically. It adopts a completely different design from the purifiers of other manufacturers, with a fabric wall system directly inherited from the previous IKEA model, the Förnuftig . In addition, it is available in two colors, white or black.

But what about the effectiveness ? The Starkvind can take care of a relatively modest surface (20 m²), and its air flow varies between 50 m3/h and 240 m3/h . For comparison, in the same price range, the maximum flow rate of the mi air purify 3 h is 380 m3/h. The Ikea model is therefore a bit lazy.

In store and online, the version to be placed on the floor is offered at 150 euros, the Table version at 190 euros.

Why choose Ikea Starkvind purifiers ?

• A unique design, to highlight or camouflage in a piece of furniture
• Cheap filters
• Ease of use

Everything you need to know about air purifiers

What are the benefits of an air purifier ? Why buy one ?

You can invest in an air purifier for various reasons. This type of device is advised to improve the respiratory well-being of people with allergies (pollens, animal hair, mites, etc.), asthma or pulmonary diseases. But it will also be useful against emanations and bad odors, especially those of cooking and cigarettes. It will also have all its usefulness to counter viruses and bacteria in suspension. Some models are also capable of filtering carcinogenic gases such as formaldehyde, harmful to the whole population.

What are the different filters used on air purifiers ?

The vast majority of air purifiers for the general public are based on a triple filter system:

• A pre-filter, which stops the largest particles such as dust and hairs. The latter is generally made of fabric. By first stopping the biggest, it avoids an overly rapid fouling of the other two filters.
• An activated carbon filter, which notably takes care of neutralizing odors. The coal in question is most often obtained by calcination of coconut. He takes care of neutralizing the particles in suspension such as cigarette smoke, the fumes of scented candles, incense ..
• A HEPA filter, which captures up to 99.995 % of particles whose diameter is greater than or equal to 0.3 micron. Most consumer purifiers have a HEPA 13 filter.

In addition, some sophisticated models are able to retain formaldehyde: in this case, a specific filter is added. The formaldehyde, which we know better under the name of Formol in its liquid form, is commonly found in our interiors. It is widely used for its disinfectant and fixative power. It is thus present in DIY and maintenance products, in paintings, on furniture, in plastic materials … However, this molecule is carcinogenic.

How to clean the exterior and the filter of an air purifier ?

It is good to clean the outside of your purifier yourself, where air is captured, especially by passing a cloth to remove possible dust. Then the filters should be regularly replaced, usually when your device tells you. This generally intervenes once or twice a year, but it all depends on of course on the model but above all on the regularity of use. It is essential to change these filters, otherwise the purifier becomes useless – even if at first glance, you think it works.

How to choose the best air purifier ? Our complete guide

Kitchen, cigarette smoke, scent of paint, or frying, and invisible particles in suspension make up a good part of the air that you breathe at home. Find the best air purifier with this guide to purify and clean up the air in your interior. Some models are even equipped with a fan function, particularly welcome during the summer period.

Spring pollens and allergens gradually give way to the heat. To protect ourselves from scorching temperatures, we caulled ourselves in our dwellings thinking that we breathe better. However, indoor air is not free from danger.

For further

Believing that you breathe better at home is a lure. The air we breathe at home is no less polluted than the air breathed in the street. The floors, the furniture, the daily activities such as cooking and cleaning are the cause of emissions of fine particles and other volatile organic compounds, abbreviated cod. In too high concentration, these microscopic gases and particles are toxic to more or less long term, and can be responsible for allergies, respiratory diseases and cancer.

Daily ventilation of your living space is a first measure to circulate the air and clean it up. Adjusting an air purifier is the best way to drastically filter and decrease the concentration of toxic compounds in suspension and renew the air. As we understand that indoor air is not as healthy as you imagine, the models are multiplying on the shelves.

Numerama helps you decipher the sometimes complex technical sheets and guides you in the choice of air purifier adapted to your situation. Our colleagues in Frandroid also have a more extensive comparison on air purifiers.

The comparison of these models is practiced on four criteria that we consider important beyond the quality of purification, obviously present on these references. It’s about noise emitted by the machine, her weight, the surface that the purifier is capable of treating as well as its Additional features, like connectivity. We have also given some importance to maintenance cost, in particular by specifying the price of replacement filters.

Actor for many years in the welfare sector of the habitats, the Korean manufacturer has specialized in the sanitation of indoor air since 1994. Often cheaper than the models offered by the traditional highly known public brands in France, the Coway Air Purifiers are of formidable efficiency.

Presentation of Coway Mighty

Connect a Coway

You can control a Coway Mighty with your smartphone or program automation by connecting it to a connected socket (example: Philips Hue Smart Plug). The “on” position is reset as soon as the purifier finds the current and the “auto” mode adjusts the power.

The Coway Mighty sports a 43 cm high cubic shape 46.9 cm to be placed on the floor or on a piece of furniture. Robust, it is around twenty centimeters wide, weighs more than 7 kilos and has an integrated handle at the rear to easily transport it from one room to another. On the top, a control banner reveals a light indicator indicating the surrounding air quality. It is not possible to control the mighty remotely and a remote control would have been appreciable. Nevertheless, the keys are quite intuitive and make it possible to adjust the power, to activate or not the ionization or to program a timer.

Operation and maintenance of filters

Three powers are possible in addition to a “auto” mode and an “eco” mode. Automatic mode simply adapts power to the degree of air pollution, while eco mode performs an air analysis every thirty minutes. If the air is holy, the purifier goes out until its next measure. Rather silent, the noise level reaches the 63 dB at the maximum at full power and is more discreet at the lowest speeds by barely exceeding 41 dB. It is designed to clean up enclosed spaces of around forty square meters, but it turns out to be just as effective on larger areas.

There are three layers of very distinct filters. A first pre-filter takes care of recovering the biggest dust, hair and other dirt. It is washing manually and does not replace. A second coal filter captures and neutralizes odors. Coway recommends replacing it every six months. A Greenhepa filter constitutes the last layer of filters and retains the smallest particles, with a diameter less than 0.01 micron. The majority of viruses and bacteria will not resist it. This filter is to be changed annually. The brand is selling an annual pack with a HEPA filter and two coals filters for fifty euros. The filters are easily replaced by removing the facade from the device.

The brand talks about a filter renewal every three years where the average is more over a year. However, the filter is not given and costs just under 80 €. The application is responsible for warning you when the filter must be replaced.

Essential characteristics to remember

TOWN THE CORE 300 Levoit

The brand accurately takes up the shape and design of many purifiers. Round in shape, it can be easily landed on a piece of furniture and blend into the decor of a living room or a bedroom. Its height does not exceed 36 cm and its diameter measures 24 cm. The device is surmounted by a digital screen allowing speed adjustment, activating the standby mode, triggering a timer and accessing the state of the filters. A button allows you to completely turn any light source so as not to be disturbed in the case of night use. No connectivity for this model of just over a hundred euros. However, for an additional € 50, the Core 300s will fill the followed house followers.

Operation and maintenance of filters

The Levoit is satisfied with a simple use in full efficiency. Three different speeds in addition to the standby mode are present. The Levoit Core300 does not climb multiple sensors to adapt the filtering power to air quality, which does not prevent it from effectively eliminating 99.97 % of the particles and compounds volatile present in the piece. The Levoit Core 300 is the quietest purifier of this guide with only 25 dB of noise level in its standby mode. Initially designed for parts of around twenty m², at full power, the Core300 levoit achieves remarkable performance with larger surfaces.

Levoit incorporates in its purifier a hepa 13 filter which has already proven itself on mites, animal squams, spores of mold and other allergenic dust. The HEPA filter is of course not the only one and is superimposed with a nylon pre-filter and an anti-coal-to-room filter, to form a single unit. The brand is the only one to offer different specific filters such as an anti-bacteria filter, another anti-escape or one for animals. Effective on the famous PM2.5, the basic filter is more than enough, because it is designed to filter the particles up to 0.3 micron. The maintenance of the filters must be done every 6 to 8 months and a wear indicator lights up when it is time to replace them. The filter is at € 45 on Amazon.

What air purifier to buy: everything to choose the right

Who is the best air purifier on the market ?

We recommend the Coway AP-1512HH Mighty for its unbeatable value for money, but it all depends on the use you will. In order to choose the right machine, we advise you to pay attention to these few criteria:

• The weight and mobility of the purifier, especially if you plan to move it from one room to another in your home.
• Noise, especially if you want to arrange it in your room.
• The optimal surface for which the purifier has been built.
• The frequency with which filters should be changed.
• The price of replacement filters.

Other parameters are to be considered as the presence of an automatic mode, a remote control or connectivity. The shape and design also occupy an important place if you want to keep a certain harmony in a room.

In terms of efficiency, certain criteria put forward by manufacturers are difficult to interpret. This is particularly the case with the frame measurement, the size of the particles or the quality of the HEPA filter.

What is the frame of an air purifier ?

English acronym for clean Air Delivery Rate, the Cadr designates the purified volume of air by the purifier in a given time for a precise particle diameter. The cadres found on purifiers are valid for pollen, smoke and dust. Often expressed in cubic meters per hour (m3/h), it reflects the performance of the purifier to its maximum power in a very specific environment.

As you will not necessarily always use the strongest speed of the purifier and we do not know where you plan to install it, we have not deemed relevant to put this value forward. Some manufacturers, such as Dyson, do not consider it useful to reveal this measure and prefer to do independent tests.

Size and classification of fine particles

Another complex criterion which requires some explanations, the size of the filtered particles. 0.3 micron, 0.003 micron pm 2.5, when you don’t know anything about it, you might think in a fair in the next Loto figures.

Fine particles below 10 microns are considered dangerous by the WHO. For a comparison order, a human hair has an average diameter of 60 microns. Needless to say, below 10 microns, these particles are invisible. The problem is that the more thin they are, the easier they infiltrate in our body by the airways.

There is an international classification of these particles according to their size. These aerial components are called PMs, taken from English to change, which means Matter Particular (Particle of Material in French).

Name	Size diameter	Examples
PM 10	< 10 microns	– pollen – mold – dust
PM 2.5	< 2,5 microns	– combustion – VOCs
PM 0.1	< 0,1 micron	– nanoparticles – COVID VIRUS

HEPA filters

It is the HEPA filter that will take care of retaining the fine particles contained in gases such as formaldehyde. HEPA filters are classified according to their performance. Only HEPA E10 and E11 filters retain less than 99 % of fine particles. In this guide, HEPA filters all have an efficiency greater than 99 %.

What is the interest of an air purifier ?

People with asthma or allergy will see there any immediate benefit. The air purifier will alleviate symptoms such as throat irritations, tearing and other inconveniences.

People who smoke or vaping will also find a certain utility to get rid of smoke and the odor not always very pleasant. Not to mention the effects of passive smoking that a purifier helps to reduce without completely eliminating.

A purifier is also useful to reassure parents concerned with the air breathed in by the little ones.

Interior pollution is invisible and its long -term consequences justify taking precautions. Investing in a good air purifier is beneficial for everyone.

How to know if you need to purify the air of your home ?

In a very factual way, bringing you a device fitted with sensors capable of analyzing the composition of the air. Depending on the price and the ranges, the air analyzer will give you more or less reliable and precise measurements of the composition of the air in gas, fine particles or in percentage of humidity.

These small devices are expensive and high -end air purifiers often have sensors capable of telling you the air quality. Either you will find purifiers indicating a concentration rate in the air in formaldehyde, for example, or a color light indicates to you whether the air is good or not.

Another way to know if your home air needs a good sanitation is the overall state of your health. If you start to have your eyes that bite or skin, maybe purifying the air of your interior is not a bad idea.

Does a purifier remove the dust ?

Yes. Air purifiers all have a pre-filter responsible for capturing the largest dust, animal hair and hair.

Normally, dust and other invisible particles challenge the laws of gravity. Their lightness and small size are not enough for these particles to fall to the ground. When the air purifier is provided with an ionization system, negative ions are sent and will be attached to very small particles like dust, allowing them to fall on the ground. They will then be able to be sucked or swept away.

Do air purifiers eliminate odors ?

Yes, if they have a coal filter. Purifier filters are often made up of three layers. The first is the famous pre-filter responsible for capturing the largest dust and the largest particles. Then comes a coal filter. It is this one that will capture and retain the particles responsible for bad odors such as those of cigarette smoke or frying.

Are air purifiers effective ?

Yes, in any case those present to you in this guide. For the most part, they have proven themselves during tests. The proper maintenance of filters is essential to ensure effectiveness over time.

If air purifiers and HEPA filters do remarkable work, they cannot eliminate 100 % of particles, viruses and other microbes. They complement the standard hygiene measures respected and strengthen the effectiveness of good daily ventilation.
