Which Factors to Look For When Buying an Air Purifier?

Published

on

An air purifier has many benefits, but not all units are equal. From asthma to pollution levels, here’s what you should know before putting your money down explains TR Ganesh, General Manager, Blueair Middle East.

As the weather begins to shift and the cool winters make way for fog and dust storms, UAE residents are bracing for another round of allergies, asthma and seasonal respiratory disorders. The problems are compounded by rising pollution levels, with major urban areas in the country exceeding the World Health Organisation’s guidelines levels for airborne particulate matter by more than three times. Thankfully, authorities are embracing change by adding monitoring stations and endorsing apps to empower residents.

Raising air quality is a key issue of the UAE National Vision 2021 agenda, which aims to raise air quality from its current level to 90 per cent by 2021. Yet, public action alone will not help and consumers must play their part. City residents spend as much as 90 per cent of their time indoors, but air within homes and offices can be between two to five times worse than it is outdoors, the United States’ Environmental Protection Agency (EPA) says.

Little wonder then that air purifiers have emerged as a potent new weapon in the battle for optimal health as individuals seek to ensure their own wellbeing. Air purifiers clear away dust, allergens and other pollutants such as smoke, odours and pet dander quickly and effectively – game-changing qualities that consumers have begun to realise. Global sales of these essential household healthcare devices are expected to grow over 30 per cent over the five years to 2024, according to the latest data from Research and Markets.

But what separates a great air purifier from the merely good? There are a number of factors buyers should keep in mind to reap the most health benefits with minimal discomfort.

Does it do what it promises?
As you might expect, not all air purifiers are the same. There are a wide range of technologies on the market, and buyers should do their homework before making a final decision. The key determinant should be the type of filter used. Activated carbon filters, for example, are made from wood, coal or coconut shells and are highly absorbent but do not effectively remove dust and many airborne particles.

Air ionisers remove pollutants but do not carry away odours. Industry opinion appears to have settled around High Efficiency Particulate Air (HEPA) filters, which were first developed in World War II to remove radioactive contaminants. Made from fibreglass, they remove 99.97% of all particles as small as 0.3 microns and are thus considered the most effective products in their category today.

What particles does it filter out?
For those with asthma or respiratory allergies, it is important to identify what sets off an attack – and steer clear of these triggers. While pet dander may set one person’s nose running, another’s respiratory system may strenuously object to even the slightest speck of dust. Air purifiers are meant to refresh the indoor environment by removing airborne particles and keeping the airflow circulating within a room, but again, not all brands are equal. It is worth taking a few extra moments to find out if a specific trigger is filtered out or not – doing so saves you from making an expensive and pointless purchase.

How does it handle ozone?
With a wide range of air purifiers on the market, several brands fall on opposite sides of the ozone line. The oxygen allotrope has both positive and negative effects. Known for its protective qualities at the edge of earth’s atmosphere, the inherently unstable gas reacts with and eliminates strong odours and airborne chemicals, so some manufacturers market ozone generators that carry away unpleasant smells and kill mould and mildew.

However, not only can ozone irritate the airways on sunny days, but at the levels required to be effective on these fronts, it can cause long-term health damage when it reacts with the eyes, skin, lungs and other exposed areas. The antioxidant can also be fatal to pets. For these reasons, the US state of California has banned ozone air purifiers, and healthcare experts recommend air purifiers that do not generate any level of ozone.

How quiet is it?
Whether it is street traffic or devices such as our smartphones and tablets, we live in a noisier world than ever before – and it is taking its toll on our health. Scientists now confirm that elevated workplace or environmental noise can result in hearing loss, irritability, hypertension, ischemic heart disease and sleep disturbances. Air purifiers are often prescribed to help improve sleep, but if the unit in question is noisy or plays music, it may not entirely deliver on those benefits. Question the retailer about the unit’s noise levels before purchase, and make sure to buy only whisper-quiet products.

Does it fit your style?
To borrow from Marie Kondo, why shouldn’t an air purifier spark joy? There is no reason health improvers should look like ugly boxes that detract from your interiors scheme. Technology has now evolved to the point where gadgets can be both beautiful and utilitarian, and thankfully for the house-proud who care about aesthetics, there are now a range of appealing air purifiers that add value to any design scheme. You can find products in bright colours that double up as a conversation pieces or pick an unobtrusive shade that blends into the background without looking ugly. After all, it is your home and it should reflect your tastes.

Why You Should Use a VPN While Traveling

Published

on

According to a survey conducted by NordVPN, 50% of travellers use public Wi-Fi while on the road. However, only 20% of them use a VPN (a virtual private network) to protect themselves while being connected to a public network. “Travelers connect to public Wi-Fi in airports, cafes, parks, and trains. Some even use public computers to print their visa information or flight tickets. A VPN in those cases is crucial if you want to make sure that your vacation will not be ruined by cyber criminals. Nobody wants to lose access to their device or their bank account during a trip to a foreign country,” says Daniel Markuson, a cybersecurity expert at NordVPN.

As International VPN day (August 19th) is just around the corner, Markuson lists all the benefits offered by the service.

Enhanced online security
The main purpose of a VPN is to keep its user’s online connection secure even when they are away from home. Hackers can set up fake hotspots or access unsecured public routers and this way monitor users’ online activity. Once a user is connected, criminals can intercept their internet traffic, infect the device with malware, and steal their victim’s personal information.

When authenticating themselves on public Wi-Fi, users often need to type in their email address or phone number. However, if a user has accidentally connected to a hacker’s hotspot, they could be exposing themselves to real danger.

A VPN hides users’ IP addresses and encrypts their online activity. That means that, even if a user is using a malicious hotspot, the hacker behind it won’t be able to monitor their activity. Therefore, getting a VPN for travelling abroad is essential if you want to stay secure and private online.

Grab the best deals
Depending on the country in which you’re located, the prices for airline tickets, car reservations, and hotels might vary. That’s because businesses know that people in different countries can and will pay higher amounts for certain products and services. If you use a VPN for travel, you can hop between servers in different countries and find the best deals available.

Make the best of additional VPN features
As the industry is evolving, many VPN providers add new features to make their users’ experience even more wholesome. NordVPN, for example, recently added the Meshnet feature that lets travellers connect to other devices directly no matter where in the world they are. This enables users to form a remote connection with their home or office PC from anywhere in the world to share files or for other uses.

However, having said that, please check local laws and regulations about using VPN services on your devices, before you do.

Social Media Data Leaks Account for 41% of All Records Breached

Published

on

Written by Edward G, Cybersecurity Researcher and Publisher at Atlas VPN

Social media is quickly turning into a primary security weak point. A single data breach within one of the major social media networks can result in millions of records being stolen. Within the past few years, we have seen multiple large-scale data breaches involving companies like Facebook and Twitter. Yet, we rarely see the bigger picture.

Luckily, data presented by Atlas VPN gives insight into the scope of the issue. It turns out that 41% of all compromised records in 2021 originated from social media data leaks, which is a significant upsurge compared to 25% in 2020. The data presented is based on the 2022 ForgeRock Consumer Identity Breach Report, which gathered data from various sources, such as 2021 Identity Theft Resource Center, IBM Ponemon, TechCrunch, Forrester Research, as well as UpGuard, and IdentityForce.

A few other factors make social media a security weak point within the current online landscape. First, criminals can prey on business clients by posing as the company in order to obtain credentials. This is becoming especially prevalent since companies increasingly use social networks to communicate with customers.

Second, fraudsters frequently attempt to infiltrate businesses by leveraging mutual connections, which create a false sense of security. Moreover, people who overshare on social media make it simple for thieves to locate personal information that aids in company breaches.

Besides social networks, another major source of leaked information is the retail sector, which accounted for nearly a quarter of all records breached in 2021. According to the U.S. Department of Commerce Retail Indicator Division, e-commerce sales increased by 50% during the pandemic. Retail data breaches increased in frequency and severity during the same period.

While the average cost of a retail breach was $2.01 million in 2020, it increased by 63% to $3.27 million in 2021. Customer credit card, payment information, and personal data were the principal targets of retail data breaches. E-commerce websites and applications sometimes skip security precautions like two-factor authentication (2-FA) as they seek a simple user experience.

When the enormous volumes of personal data that retail websites collect are not adequately protected, it creates the ideal environment for breaches and subsequent fraud. Finally, the healthcare sector is worth mentioning with only 1% of records, yet, at the same time, the information leaked is usually particularly sensitive.

Data compromised from healthcare institutions tend to include name, address, SSN, date of birth, and, in two-thirds of the breaches, actual medical history information. With this information in hand, cybercriminals can blackmail companies or even particular individuals.

To round up the findings, it’s obvious that retail and social media companies should go the extra mile in securing their customer information. In addition, even though healthcare providers leak only a fraction of the data, they should still safeguard their client data with particular care due to the sensitive nature of the information.

Some services offer data breach monitoring tools. Data breach monitors track any data breaches related to your online accounts. It automatically scans leaked databases and informs you of any past or recent breaches where your personal information was exposed.

As always, we must mention the most effective countermeasure against data leaks. It is advised to enable multi-factor authentication on all of your accounts that offer the functionality. This way, even if your credentials are compromised, threat actors will not be able to access your account unless you lose your phone, and it is also found by ill-meaning individuals, which is less than likely.

Airline and Booking Services Scams Intensify at the Height of the Holiday Season

Published

on

Vacation season is well and truly upon us, and travellers around the world are looking for interesting places to go, cheap places to stay and reasonably priced flights. And scammers are here to give them what they need — well, sort of. Kaspersky researchers have observed intensified scamming activities, with numerous phishing pages distributed under the guise of airline and booking services. To help travellers avoid scams, company researchers share some of the most widespread fraud schemes used to lure victims as well as helpful tips on how to plan a safe, scam-free, vacation.

Fake Ticket Aggregators
Most trips start with a plane or train ticket, and travel enthusiasts are often interested in getting their hands on a bargain. Kaspersky experts have seen numerous fake websites claiming to offer users the chance to buy aeroplane tickets at cheaper costs. Such websites are usually well-made phishing pages that mimic famous airline services and air ticket aggregators. Some of these websites even display the details of real flights, with experienced phishers sending search requests to flight aggregators and displaying the information received from them. However, instead of delivering on promised flight tickets they keep your money and use your personal information for malicious purposes (e.g. selling your bank details and identifying information on the dark web).

Fake Lotteries for Discounted Tickets
There are also plenty of fake pages attempting to lure travellers with aeroplane ticket draws, lotteries and gift cards. Users are offered the opportunity to take a small survey and enter their personal details in exchange for a generous discount on a flight ticket. As with many other offers that seem to be too good to be true, such websites end up being phishing sites, collecting victims’ personal information and card details.

On top of this, the survey usually ends with a request to distribute the site among friends to receive the prize. In such cases, cybercriminals are using the victims themselves as a tool for spreading the scam further. A link sent by people you know seems more trustworthy than one received from a stranger. If the user then follows the link and tries to get their prize, they often find they need to pay a commission or fee first. After this money is paid, the cybercriminals disappear – without rewarding the user.

Fake Rentals
Another popular tactic used to scam travellers is fake rental services. One example includes the offer of a luxury two-bedroom apartment close to the centre of a European capital for just €500 a month. Another seemingly appealing offer is for the rental of an entire four-bedroom house with a pool and fireplace for only €1,000 for the whole month. The reviews describe amazing vacations and hospitable hosts. This encourages users to pay for their month-long stay, but in reality, they end up sending their money to fraudsters.

“Planning a vacation is not easy. People can spend weeks, even months, looking for the perfect place to stay and the tickets to get them there. Fraudsters use this to lure users that have grown tired of searching for great deals. After two years of flight restrictions imposed by the pandemic, travelling is back. But so are travel scams – with intensified scamming activity targeting users through fake booking and rental services. Such attacks are totally preventable, which is why we urge users to be sceptical about overly generous offers. If an offer seems too good to be true, it probably is,” comments Mikhail Sytnik, a security expert at Kaspersky.

To keep yourself protected while planning a vacation, Kaspersky experts recommend:

  1. Carefully look at the address bar before entering any sensitive information, such as your login details and password. If something is wrong with the URL (i.e. spelling, it doesn’t look like the original or it uses some special symbols instead of letters) don’t enter anything on the site. If in doubt, check the certificate of the site by clicking on the lock icon to the left of the URL.
  2. Only book your stay and tickets through the trusted websites of trusted providers. Ideally, type the address of their website manually in the address bar.
  3. Not clicking on links that come from unknown sources (either through e-mails, messaging apps or social networks).
  4. Visiting the business’ official website if you see a giveaway offered in e-mail or on social media by a travel company or an airline to confirm the giveaway exists. You should also carefully check the links the giveaway ad leads you to.
  5. Using a good security solution that can protect you from spam emails and phishing attacks. We recommend Kaspersky Security Cloud.
