Having a low blood oxygen level can be very risky and anybody suffering
from it might feel difficulty in breathing, exhaustion, and confusion,
which can directly affect your decision-making abilities. If the Oxygen
level in the blood drops way too much it can hurt the functions of vital
organs like the brain and heart.
It is in such a situation that Oxygen Concentrator comes as a
huge help. It can be really helpful for someone suffering from low
blood oxygen levels.
How Does An Oxygen Concentrator Work
The portable oxygen concentrators are a great choice for extended
travel and short-term trips, home oxygen concentrators are built for
long-term use at home. The oxygen concentrators work by separating
oxygen molecules in the air from the nitrogen molecules to form a
concentrated gas made up of 90–95% pure oxygen. Normally, the air we
breathe is made up of 79% nitrogen and 21% oxygen. Home oxygen
concentrators flip that ratio on its head to create a gas that is almost
pure oxygen for therapeutic purposes.

How To Choose The RIGHT Oxygen Concentrator
Before buying an Oxygen Concentrator, there are certain things that you need to keep in mind such as:
- Flow Rate
Indeed one of the most important factors to consider when buying an
oxygen concentrator is to check its flow rate capabilities. Flow Rate
indicates the rate at which oxygen is able to travel from the machine to
the patient.
An ideal process is that a doctor should advise the ideal flow rate
for a patient, thus it is recommended that you discuss any potential
oxygen concentrator purchases with your doctor first.
Some oxygen concentrators may have lower flow rates (in the range of
250 to 750 milliliters per minute) and there are others that may offer
higher flow rates (such as the 2 to 10 liters per minute range). Since
not all oxygen concentrators provide the same range of flow rates, it is
very important that customers keep a check on the flow rate offered by
the product.
- Power Consumption
Oxygen Concentrators generally draw power from any regular wall
outlet just like any other home appliance. But, the amount of energy
this device uses differs widely. While it is advisable to purchase the
concentrator that boasts the lowest power consumption, your oxygen
requirements, as prescribed by your doctor, might lead you to a device
that consumes a bit more power. Besides, there are some models that come
with an option of working on consumer-grade batteries as well, which is
helpful if the power goes out.
- Portability
Another important aspect for you to look out for is how mobile you
will need your concentrator to be. Oxygen concentrators can range
significantly in size and portability.
There are some units that are high-powered and designed to work hard
and provide higher flow rates, but are typically larger and heavier.
These models are often designed to deliver higher flow rates, and are a
great solution for in-home use.
Then there are others that are much more portable, typically
weighing between 2 to 4 kgs. These portable oxygen concentrators
sacrifice higher flow rates in order to be significantly easier to
transport and use while out and about. This makes them the perfect tool
for patients who do not require high oxygen flow rates.
- Oxygen Concentration
After being compressed and filtered within the concentrator, the
oxygen that is delivered to the patient has a particular percentage of
pure oxygen content. This value is referred to as the oxygen
concentration. This level of oxygen concentration is affected by the
design of the filtration system included in the particular oxygen
concentrator, as well as the effectiveness of the concentrator’s
nitrogen-removing sieve system.
Though the major chunk of oxygen concentrators have a concentration
value between 87 to 99 percent, this value can vary between oxygen
concentrators. Typically, higher-powered products that are designed for
patients who require high oxygen flow rates are also capable of
providing higher oxygen concentrations, whereas lightweight, portable
oxygen concentrators for patients on the go do not usually require the
highest oxygen concentrations.

- Noise Level
Home oxygen concentrators work by drawing in air from the
environment and filtering out the oxygen—which can produce some noise at
times. If you are sensitive to noises, you might want to consider a
concentrator that operates silently. The concentrators on this list
range anywhere from 40–58 decibels of sound. For context, 40 dB is
equivalent to bird calls or the ambiance of a standard library. On the
other hand, 60 dB is equivalent to a close conversation or a running air
conditioner.
- Warranty
Just like any appliance, the oxygen concentrator will have a
warranty. However, each manufacturer has a different warranty policy.
Since these devices are built to last a long time, it is a good idea to
review the warranty policy beforehand to make sure you get every bit of
functionality you are paying for.
Conclusion
Oxygen concentrators can be life
saving appliances and are invaluable for its convenience and effective
delivery of oxygen to those patients who cannot get enough on their own.
These devices utilize the ambient air in any room to filter, process,
and compress, then ultimately deliver purely oxygenated air to those who
need it.
However, before buying one or using
one yourself you are advised to consult a doctor. A professional doctor
will be the right person to guide you through its needs and usage.

In between their prayers, these children would arrive at the doorsteps of houses. The tradition of handing out treats on Halloween originated from the holiday of All Hallows Day, also known as All Saints Day, deriving from Christian tradition. Some candies continue to be popular with US trick-or-treaters, such as Reese's Cups, which was the top chocolate Halloween candy of 2025, and Skittles, which were the top non-chocolate candy. The process of going door to door to receive free candy during Halloween has become a draw for children, particularly in America.
These soul cakes resembled a form of biscuit and were usually filled with raisins or cinnamon among other ingredients, giving these children the incentive to pray in exchange for sweets. The main form of candy passed out is pre-packaged sweets, due to parents feeling more comfortable allowing their children to eat pre-packaged candies because of the quality control. We stock over 500 lollies, chocolates and sweets from iconic Aussie favourites like Allens Snakes Alive, Killer Pythons, Red Skins and Sherbies, to retro classics like Milk Bottles, Freckles, Musk Sticks and Curly Wurlies. Contamination by infectious agents such as virus or bacteria is unlikely through sweets, including unwrapped sweets. Heavy or frequent consumption of high-sugar foods, especially lollipops, sugary cough drops, and other sugar-based candies that stay in the mouth for a long time, increases the risk of tooth decay. Even in a culture that eats sweets frequently, candy is not a significant source of nutrition or food energy for most people. The category, called sugar confectionery, encompasses any sweet confection, including chocolate or chewing gum.
When these bacteria metabolize the sugar found in most candies, juice, or other sugary foods, they produce acids in the mouth that demineralize the tooth enamel and can lead to dental caries. Candy generally contains sugar, which is a key environmental factor in the formation of dental caries (cavities). Some candy, including marshmallows and gummy bears, contains gelatin derived from animal collagen, a protein found in skin and bones, and is thus avoided by vegans and some vegetarians. Among the Bengali people, candy may be eaten for an entire meal, especially during festivals.
However, the widespread availability of bulk confectionery has made Swedes the world's largest consumers of candy since at least 2009. A 1959 Swedish dental health campaign encouraged people to reduce the risk of dental problems by limiting consumption of candy to once a week. The phrase like taking candy from a baby is a common simile, and means that something is very easy to do. Poisoned candy myths persist in popular culture, especially around trick-or-treating at Halloween, despite the rarity of actual incidents. If the material attached to confectionery has a function and will not cause any injury to the consumer, it is allowed to be marketed. Non-nutritive toy products such as chocolate eggs containing packaging with a toy inside are banned from sale in the US.
Pan work candies include nuts and candies such as jelly beans and sugar-coated almonds, made by coating with sugar in revolving copper kettles. These innovations made it possible for only one or two people to successfully run a candy business. Even penny candies were directly descended from medicated lozenges that held bitter medicine in a hard sugar coating. For this reason, candy store-owners relied almost entirely on the business of children to keep them running.
One of these candies, sometimes called chamber spice, was made with cloves, ginger, aniseed, juniper berries, almonds and pine kernels dipped in melted sugar. At that time, it began as a combination of spices and sugar used as an aid to digestion. Before the Industrial Revolution, candy was often considered a form of medicine, either used to calm the digestive system or cool a sore throat. Candy is still served in this form today, though now it is more typically seen as a type of garnish.
Chocolate is sometimes treated as a separate branch of confectionery. Noncrystalline candies are homogeneous and may be chewy or hard; they include hard candies, caramels, toffees, and nougats. Hard-boiled candies made by the vacuum cooking process include stick candy, lemon drops and horehound drops.
This is in part because bacteria can not replicate in the very dry and sweet environment of candy. This is chiefly a concern for people with diabetes, but could also be dangerous to the health of non-diabetics. Most candy, particularly low-fat and fat-free candy, has a high glycemic index (GI), which means that it causes a rapid rise in blood sugar levels after ingestion. Cleaning the teeth and mouth shortly after eating any type of sugary food, and allowing several hours to pass between eating such foods, reduces the risk and improves oral health.
