Air Purifiers

December 16, 2011 By Leave a Comment

A lot of people are concerned about the environment in which they live both at home and at work. The stories of pollution are grounds for immense anxiety to a lot of people.

A great deal of individuals blame their allergies and other skin conditions on ‘bad air’ and there is proof to support their conjecture as well.

One remedy for ‘bad air’ that people are turning to is that of air purification. Air purification can be achieved with a dedicated air purifier or by use of high-powered filters in an air conditioning system.

It is usually cheaper to adapt an existing air conditioning system than to buy a new air purifying unit, particularly if you want this new, clean air to be available in each room of your house.

Air purifiers are apt to work best in small confined spaces like an office or a child’s bedroom. lots of the firms that make air purifiers boast that they will purify the air in a room of 180 square feet. Well, OK, but let us merely stop and think about that.

That is a room of 15 feet by 12 feet – I am six feet long, so what they are really talking about is a decent sized bathroom or a small bedroom. For that, you pay about $150, but you do not have to buy new filters, says the company proudly, you can wash and reuse the old one.

Others use replacement filters. These units are normally a little cheaper. They will filter (decontaminate) the air in approximately the same space, but the filters can cost $50-$60 each. They frequently use what are known as HEPA filters and they are (or can be some of the best on the market.

It is definitely worth bearing in mind the term HEPA filter, once you have made up your mind how you are going to suck or pump air through it.

If you are searching for an air purifier because you spend a lot of time in one room, particularly if the windows open onto a busy street or your spouse smokes, procuring a portable air purifier could be an solution for you, but check the specifications very carefully against the size of your room.

If you scrimp on the cost of an air purifier, you have thrown your money away – you may as well have tied a hanky across your nose.

Powerful, expensive air purifiers will work well in a limited space, but are portable and will probably do a better job than an air purification system affixed to your air conditioning unit.

However, if you would like to raise the general standard of the air right through the whole house in one fell swoop, you cannot beat attaching a high quality HEPA filter to a central air conditioning system.

If you use a stand-alone air purifier, you will have to keep the doors shut to keep your clean air in and nag everyone to keep shutting the doors as well, but with an air purifier attached to a central heating unit, you can live normally.

Facts About Chocolate’s Origins

November 24, 2011 By Leave a Comment

The Theobroma Cacao or ‘the food of the Gods’ is what we all know as the cocoa tree. It’s origin can be traced back to South America’s rain forests, specifically to Central America, although historians are still debating over certain facts surrounding this tree.

It is suggested that the Mayans first grew the cacao tree in 300 AD, although others point to inadequate evidence that it was grown or at least harvested in around 3,000 BC. The Aztecs also used the cacao, but from about 1100 AD.

The chocolate (drink) that we all know today was called ‘xocoatl’. It was a very exclusive beverage that was made with cacao, chilies, anise seed, vanilla, corn meal and some other spices. It is believed that only royalty were allowed to drink it and then only from golden chalices, which were to be used for the purpose only once.

The cacao tree is very sensitive to its environment and it most often grows in the shade of the rain forest canopy. If only for this reason alone, chocolate lovers should join forces with the environmentalists to save the rain forests so that the cacaos will continue to exist.

This tree is unusual because its fruits grow directly on its branches and trunk; midges cause the pollination of the flowers during the night time.

The cacao tree is very productive, but not very fruitful. It can have in the region of 10,000 blossoms, but only about 10 to 50 of those will mature into fruits or pods. This is thought to be because the cacao tree can adjust the number of blossoms that will mature according to its ability to handle the energy loss of bearing fruit or pods.

The cacao tree regulates itself in this way to preserve its health. Too many pods might exhaust its energy so much that it could not survive a viral or insect attack or too many ripe pods might snap off its branches.

The cocoa beans come within the pod, the fruit of the blossom. Harvesters wait for the pod to ripen. They will then crack open the pods and take out the seeds, which are surrounded by a white pulp. This is thrown away these days, but it is thought that many years ago it was fermented into an alcoholic drink for ceremonial purposes. The beans are the source of chocolate, although there is plenty to do yet..

The seeds are very bitter at this stage and it is for this reason that they will go through a procedure of fermentation for between three and seven days. This causes the seeds to go through chemical as well as physical changes. The result of this was used for the royal drink, the ‘xocoatl’.

However, to turn it into what we recognize as chocolate, the fermented beans have to go through quite a few more processes. Processes by the name of: drying, cleaning, roasting, grading, opening, separation, grinding and liquefying.

After liquefying, you have pure chocolate in the form of chocolate liquor. This is sold to chocolate manufacturers and the good ones make high-quality chocolate from it and the bad ones water it down so much that it is scarcely chocolate any more.

Memory Foam Mattresses

November 17, 2011 By Leave a Comment

Have you ever heard of a memory foam mattress? Memory foam has in fact been around since 1966 when it was developed by a team of NASA scientists, who were looking for ways to make aircraft cushions safer. Therefore a memory foam mattress is a mattress manufactured from this space age foam, although modern memory foam has been hugely improved since those early days. The difficulty with the early foam was that it was too brittle, so it crumbled within a couple of years.

Nowadays, memory foam will conform to a body’s shape by reacting to a combination of body weight and body heat depending on the density of the foam. One of the first uses of memory foam was in hospitals where it was found that memory foam could ease pressure on the parts of the body coming into contact with the foam, which reduced the occurrence of bed sores and gangrene in long-term bed-ridden patients.

The first memory foam mattresses were very costly and only institutions such as hospitals could afford them. However, over the last twenty years, the price of memory foam has fallen dramatically and so these super mattresses are now within the grasp of almost everyone who needs or wants them. There are options to the traditional memory foam mattress as well, there are memory foam pads and cushions and pillows as well.

The use of this special foam has poured into other regions of our lives as the price of it has dropped. Memory foam is now used in car seats, wheelchair seats, kids’ high chairs, earplugs, gloves and office furniture. In fact, this new foam is now used to produce many items that have to be worn or used for long periods of time – golf gloves as well for instance.

Although the price of these memory foam mattresses has dropped significantly they may still be too expensive for everyone in large families to have one each. In this case you could go for mattress toppers which are otherwise called mattress pads. These are meant to be laid on top of the mattress but under the bottom sheet. They are cheaper because they are normally between two and four inches thick.

However, be careful with cheap toppers because any foam memory foam topper that is thinner than two inches thick is likely to be ineffective. Similarly, bigger is not always better, because some individuals find memory mattresses that are over six inches thick are too hard to sleep on.

Check the guarantee too. Some high-density mattress pads of two inches thickness will crumble within a couple of years, so a two year guarantee means that you will get at least this length of time out of your memory foam mattress or mattress pad.
