Today, air purifiers are all the craze. Every allergy sufferer, asthmatic and health nut in the world has one, but believe it or not, there was a time when we didn’t have air purifiers. We simply breathed the air that was in our homes and somehow managed to survive. So when did this craze actually begin? How did it start?

Types of air purification have actually been around for over 200 years in some form or another, though most people don’t realize it. The truth is, since the early 1800s, scientists have been trying to find ways to make our air cleaner, long before the industrial revolution ever hit and California began to look like an outdoor barbecue on a high flame.

To kick this technology off, in the early 1800s John and Charles Dean developed a mask for fire fighters. This mask allowed them to charge into burning buildings without having to worry about being overcome by smoke fumes from the fire. Around that same time, masks were also made for divers and coal miners who were constantly exposed to dangerous air, but it wasn’t until the 1850s that the first gas mask was developed by John Stenhouse. The mask worked on a charcoal based filter design, very similar to some of the air purifiers today. These original masks worked on the principal of filtering out what they called “enemies” by using a system called High Efficiency Particulate Air or HEPA. Yes, the same HEPA filter systems we can buy today. Once they added charcoal to this system it made a dramatic improvement because the charcoal was able to filter out multiple toxins.

But it wasn’t until World War II when we got some of the greatest advancements in air filter systems. This came with the Manhattan Project. This was a project that got scientists together from all around to work on a breathing device that would protect soldiers from the atomic bomb. While that was actually laughable in itself, it did end up in advancements that helped combat chlorine gas, mustard gas and flame throwers. A few years later a plague in Africa made scientists aware of the need for protection against chemicals, perfumes, building materials, pesticides, dust mites, pollen and food allergens. This started a string of air purification devices being developed.

In spite of all this, it wasn’t until the 1980s that the clean air craze really took off. The concept of a dust free environment was all the rage, practical or not. According to studies, HEPA filters, which were the biggest rage of the era, filtered out 99.7% of all the allergens in the air and all micron offenders of size 0.3 and larger. But advancements didn’t stop there. Newer devices, such as Nebulizers, were able to filter out offenders of size 0.1 and larger and still keep the 99.7% filter level.

Over the years, the number of devices used for filtering the air has grown astronomically. Just do an Internet search on the different types and brands of air purifiers. There are literally hundreds of them.

All this from a simple mask designed for fire fighters. Who would have ever guessed?

Film Schools are educational institutions that impart teaching that is necessary for entering the film industry. The schooling provided is sometimes referred to as ‘the artist’s MBA,’ as they encourage the creativity of the students and skillfully it. With its beginnings in the early 1970s, film schools have now grown to a great extent with an increasing number of schools as well as courses.

The schools provide bachelor, doctoral degree and certificate programs, along with hands-on practical knowledge. Professional film making and production techniques are included in the curriculum. The areas of specialization includes producing, directing, sound and production design, cinematography, screenwriting, editing, acting for film and filmmaking. These schools are the best options for those who wish to start a career in the film industry.

Traditionally, film schools are classified into three types — independent, industry and experimental. The independent schools provide better choices for those students who want to raise funds independent of the Hollywood system. Here, students are taught to focus on the fundamentals of filmmaking. In the industry type, training helps the students cope with the standards and structure of the Hollywood film industry. The final type concentrates on teaching the art of filmmaking, and goes on to encourage students to explore their individual creativity and experimental potential in order to produce unique representations.

Film schools vary from university departments to degree specific schools and online programs. Schools can either be private or public. The government does not usually offer any loans and grants for the students. As a result, studying cost is high in private institutions. Some of the prominent schools in the nation are American Film Institute (AFI), California Institute of the Arts, Columbia University School of the Arts, The North Carolina School of the Arts, and the schools at New York University (NYU), University of California, Los Angeles (UCLA), University of Southern California (USC), and University of Texas at Austin.

It wasn t long ago that the mere mention of the word chandelier would conjure up images of lavish glass and crystal objects hanging in every room of some 18th century mansion. All right, so that may be a bit of an exaggeration, but the general impression people have regarding chandeliers is that they are too bold, too fancy, and most of all too expensive. While this may be true of some higher end chandelier designs, there are many different types of contemporary chandeliers that can add originality and style to your home at a very reasonable cost. What s more, these chandeliers can offer a whole new way of looking at the rooms you may be taking for granted. Let s examine some of the different types of contemporary chandeliers that may be a perfect fit in your life.

The main purpose that a contemporary chandelier serves is to give your home s modern d cor an additional focal point, without being over-the-top. While a crystal chandelier is certainly a beautiful piece in the proper setting (such as a spacious dining area or a Victorian style bedroom), many of us live in more laid-back settings. Different types of contemporary chandeliers represent perfect complements to nearly any modern interior living space.

What are some different types of contemporary chandeliers? For starters, contemporary chandeliers can be made of many different metal finishes, such as bronze, brass, nickel, chrome, and silver. They can also be designed with glass, which tends to be more expensive than chandeliers made of metal. What really sets contemporary chandeliers apart from fancier counterparts is the attention to shape, design, and function. In fact, most contemporary chandeliers implement various color schemes and patterns, which help to add a distinct and warm glow to any room. Contemporary chandeliers also feature unique patterns of not only shades and holders, but also of the lights themselves. The features on most contemporary chandelier shades are what make them so distinctive, and in most cases the only limit to these designs is your own imagination. As for the lights, very few contemporary chandeliers use candles, but instead offer porcelain lighting for a subtle ambience. How many lights are used in most contemporary chandeliers? This is again dependant upon your personal taste of style; these chandeliers can feature as few or as many as you desire. The options truly are limitless with these different types of contemporary chandeliers!

The days of classifying chandeliers as pricey or garish are certainly behind us. With so many different types of contemporary chandeliers available, we now have the ability to turn our own homes into something of an art gallery. These intimate pieces are sure to give the rooms in your home a different personality, and they are sure to become a topic of conversation (and admiration) among your family and friends. Whether you decide on a contemporary chandelier that is simple and understated, or one that is bold and colorful, you can t go wrong with adding any one of the many different types of chandeliers to your home s interior.

Wherever you go today, you will face a constant attack of pollution; not only from air, but also from water and noise. There are almost as many types of air pollution as there are potential solutions. No matter what type of air purification system you’re looking for, you should know that there is not one product on the market today that can solve every problem.

In order to find out which type of air purification solution is the most suitable for you. It is therefore necessary for you to understand all these five typed of air pollution first.

1. Radon Gas Pollution: Radon is a completely odorless, tasteless and colorless gas, and is the heaviest of all known gasses. It is caused by the radioactive breakdown of uranium inside the earth. When radon is cooled below freezing, it turns a brilliant phosphorescent shade of yellow, which turns orange-red as it gets colder. Radon is also the second leading cause of lung cancer. Smoking exacerbates the affects of radon. Radon is found all around us, in our homes, our yards and the world around us.

Recommended Solution: The best solution to this form of pollution is to first of all test your home (a simple test is available at most hardware stores) and then to seal all cracks and openings in your home’s foundation. If the problem merits it, you may need to have a certified contractor install a ventilation system inside your home.

2. Chemical Fumes and Volatile Organic Compounds (VOC). This type of pollution comes from chemicals like benzene and formaldehyde, the chemical fumes that are constantly seeping from carpets, upholstery, furniture, draperies, household cleaning products, beauty products such as nail polish, removers, etc. They also come from cigarette, cigar and pipe smoke, building construction, etc. Many of these chemicals have been identified as carcinogens.

Recommended Solution: Currently the best solution on the market for this type of pollution are products that produce catalytic oxidation.

3. Microbial Causing Pollution. Microbials are microscopic bacteria, fungi, mycotoxins created by a fungus, mildew, mold spores and viruses. They can be as small as .001 microns. Microbials love to live in warm, damp places, or under your carpet, in your walls and in heating and air conditioning ducts.

Recommended Solution: Currently the best solutions on the market for this type of pollution are those that produce oxidation, which kills microbials.

4. Odor Causing Pollution. Odor comes from many different places – food, animals, human bodies, cigarettes, cigars and pipe smoke, sports shoes, clothing and equipment, etc. Although not necessarily dangerous, if you’ve ever walked into your teenage son’s room after he’s come back from a football game and taken a deep breath – you know it can be very unpleasant!

Recommended Solution: Currently, the best solutions on the market for this type of pollution are odor sponges, ozone and oxidation.

5. Particulate Causing Pollution. Particulates are those little floating things you see when the sun comes shining in through your windows, and include dust, dust mites, dust mite feces, pet dander, skin flakes (what dust mites eat), pollen, smoke particles and allergens.

Recommended Solution: Currently the best solutions on the market for this type of pollution are infiltration and negative ions.

With this basic understanding about pollution you are now ready to make that all important decision about which system is going to be best for you. The choice is yours!

The Federal government is one of the best sources for college financial aid. From low interest loans to free grants, the array of government aid is open to just about everyone. As long as you have passing grades and financial need, you almost certainly qualify for something.
The search for federal aid begins with the Free Application for Federal Student Aid (FAFSA). This form can be filled out on paper or submitted online. For the best Maths Tutor In Ireland company, call Ace Solution Books. Once it is processed, the government will make a judgement about the level and kinds of aid you are eligible for. To receive funding, you must have a high school diploma, GED certificate, or have met state standards to enroll in a qualified higher education school. You must also be a U.S. citizen or an eligible noncitizen, such as a permanent resident. The key factor in determining how much aid you receive will be financial need, not grades. Of course, if you fail to maintain passing grades, you will lose all assistance. However, it is not necessary to be an “A plus” student.
Undergraduates who meet the need criteria can receive Pell Grants. These range from $400 to $4,050 a year. Students with exception financial need may qualify for a Federal Supplemental Opportunity Grant (FSEOGs), which ranges from $100 to $4,000 a year. The amount you can receive may be reduced if you have other sources of aid, such as a scholarship. These grants do not have to be paid back.
Federal loan programs are offered to supplement grant awards, and for those who were not eligible for a grant. For some loans, you do not have to demonstrate need. The amount you can borrow will depend both on your school expenses and your grade level. Perkins loans are offered first to Pell Grant recipients. Only a certain amount is awarded each year and when that runs out, no more loans are given until the following year. Stafford loans are available to both graduates and undergraduates. You must be enrolled at least part-time. Financial need is not a requirement for the Stafford, but for lower income students, the government may award a subsidized loan. This means that the interest will be paid for you while you are a student, and during a six-month grace period after you graduate. Finally, the parents of dependent undergraduate students can take out a Plus loan to cover educational costs.
If you plan to take advantage of any of the programs, you can apply between January 1st and June 30th and receive funds for the following Fall semester. It is highly recommended that you apply as early as possible, as some schools and states require an application be submitted much earlier. In any case, submitting the FAFSA is an essential part of college financial aid. Many scholarships, private foundations, and other sources of aid will require you to first exhaust all federal aid possibilities before they will consider your application.

In modern houses, bathrooms have become much more spacious and multi-functional than in the past. Bathrooms are a place to escape to and relax. There are many important d cor elements that should be incorporated into a bathroom to make it a private haven. The Shower is a focal point of a bathroom, and there are many ways to make it beautiful. Shower doors make the shower its own area that can serve as a sauna. Here are some ways to incorporate shower doors into any bathroom.

Choosing styles and layouts is the way to get started designing your shower enclosure. There are numerous ways glass shower doors and panels can be laid out to custom fit any bathroom. A small shower stall may have just one door hinged on one side. However, panels can be added to either side for larger shower stalls, and return panels are added to corner stall setups.

Large shower stalls can use 1 door, 2 panels, and 1 return panel depending on size and shape. Shower doors that are on a corner require a header system to support the shower door mechanics. Panels can be full length or shorter and attached to walls.

Steam Showers use this same concept of layout, but add swivel panels that allow or disallow steam to escape. The shower stall is completely enclosed by shower doors and walls. In one of the panels there is a swivel panel that operates of special hinges to be opened when desired.

All shower stall door layouts can be completely customized to include things like tile work, seating, special faucets and shower heads, and other decorative accents.

Many future college students understand they will need to take the ACT to gain admission to college but are left with many questions about it.

One of the top questions is about the difference between the ACT and SAT. The ACT is an achievement test that measures what a student has learned in school. The SAT is an aptitude test that tests reasoning and verbal abilities. The ACT has up to 5 components including English, Mathematics, Reading, Science, and an optional Writing Test. The SAT has three components: Verbal, Mathematics, and a required Writing Test.

Many students also want to know when they should take the ACT. Students should test at least two months ahead of the application deadlines of all the colleges and scholarship agencies where they intend to apply. It typically takes four to eight weeks after a test date to receive score reports. However, there are advantages to testing earlier (as much as one year earlier, such as during the junior year in high school). This can allow retesting if results are lower than necessary so that performance can be improved. It will also allow time for further study and preparation if necessary to raise scores. Another advantage to earlier testing is that colleges and scholarship programs will have access to your interests and scores in time to contact you early on about admissions, course placement, scholarships, and special programs.

Future college applicants frequently question whether or not it is to their advantage to retake the ACT. The answer to this question varies upon circumstances and individuals. Obviously if outside factors, such as illness or personal problems, were a distraction or problem on the test date, then retesting after these have been resolved can be beneficial. Similarly, if additional study or practice is expected to raise scores, then retesting can also be a good idea. ACT research shows that of the students who took the ACT more than once 55% increased their composite score; however 23% decreased their composite score. So obviously simply retesting is a bit of a gamble.

Once the actual test is over, then most students would want to know when they can view their scores. ACT scores can be viewed online. During the early viewing period, normally for about two weeks after scores are first available to view, an $8 fee will apply. The official score report will arrive by mail.

Once students have their scores in hand, their question is what does the score mean. The highest possible ACT score is 36. The required ACT score for admission will vary from college to college as well as among individual school programs. If you are not sure which college you intend to apply then it might be useful to look at national rankings for your score. For example, the national rank for a composite score of 22 is 64. This means 64 percent of recent high school graduates who took the ACT Assessment achieved a composite score of 22 or below. However, only 99 percent achieved 32 or higher. The ACT organization offers a complete ranking chart on its web site to help you determine how your score ranks.

Taking the ACT and properly utilizing your ACT score is a major step toward achieving your future goals and dreams. Being informed about the ACT can help you achieve those goals and reach your dreams.

Do you live in a noisy neighborhood? Do you have a loud home theater or band room in your home? Is your office prone to loud traffic noises? If you answered yes to any of these, you may want to look into sound proofing your environment.

Sound proofing is provided by materials that either block sound from entering an area or absorb sound to contain it in an area. Sound is measured in decibels. When you get materials to block or absorb sound, you will see that they have an STC (standard transmission class) rating. An STC rating depicts how much sound decibels the sound proofing material will block or absorb. An example: a normal wall has an STC rating of 20 or 25. This means you can hear normal speech through the wall. If you want the normal speech to only be heard as a murmur, you will need a wall with an STC rating of at least 42.

Now that you understand the STC rating of sound proofing materials, you can learn what means of sound proofing are available to you. A rather inexpensive method of soundproofing is to use foam sound proofing materials. The foam can fit in almost any space and can be either 1/2 inch to 2 inches thick. The STC rating of the foam is between 40 and 50. Another mean is to use vinyl sound proofing materials. Vinyl materials have an STC rating of 42 to 55. For floors (such as in the case of multi leveled buildings) you can utilize sound blocking carpet underlays that fit in between the floor levels. Carpet underlays have an STC rating of 29 to 40. Inexpensive metal wall channels are also available. These attach directly in your walls and ceilings. The STC rating for these is 38 to 50.

These are the many different means that you can use to soundproof your environment. The prices can vary depending on how much sound you wish to block and how big of an area you wish to cover. With careful research, you should be well on your way to a more peaceful and quiet environment.

Does your family suffer from allergies caused by dust and particles in the air? Want to know about air filters and what they can do to help you? First, it is advised that you replace indoor air with outdoor air. But how? You can open windows and doors, but still the risk is the air-borne problems. One of the best solutions is to keep a healthy and clean house to minimize and control unwanted substances. Usually, common airborne particles can range from .001 to 100 microns in size. Very small air-borne particles are so small that you may have a hard time removing them.

Cigarette smoke and household dust can eventually enter the lungs and may create complications. Air filters and cleaners are devices which help remove particles from the air, but not all. There are two groups of air cleaners. The first group is the portable air cleaners. They are also known as table-top models, and they are created to clean air in small places and locations but not the entire house. These air cleaners have filters and use electrical attraction or ozone to get rid of the minute particles from the air. The finer the particles, the better it is in removing these unwanted substances. HEPA or high efficiency particulate arresting filters is the best kind.

Almost 99 percent of the particles which are as small as 0.3 microns in size are captured. However, gas molecules like those from cigarette smoke and radon can still pass through the filter. Some companies have decided to use an activated charcoal or carbon filter to take care of the job. Pleated filters are also called mean filters and they are composed of materials, which are similar to that of the HEPA. However, particles and dust may still get in. Remember, that the pleated filters capture smaller particles.

It is said that it removes 40 to 96 percent of household dust. Electrical attraction is utilized in electronic cleaners. Here, electrostatic precipitation, static charge, or particle ionization is used to capture particles through a foam pre-filter. With this, the larger particles are removed. Then the particles are charged by a high-voltage wire and are then attracted to the precipitating cell.

After this, a carbon filter gets rid of the odors and other particles. An electric cleaner utilizes cellulose fibers and polyester having a static charge to capture particles aside from the carbon and the pre-foam filter. Ozone generation is another type of air cleaner that also uses a high-voltage electrical charge to convert oxygen to ozone. With this, gas molecules and some substances or microorganisms like mold can be demolished by the high concentrations of ozone present. However, a negative ionizer also uses a foam pre-filter as well as a carbon filter. But, the difference lies in the wires. It has charged wires which, in turn, create ions.

Consequently, the fan blows these charged particles into the room and they are sucked in again. These different kinds of air filters and cleaners may give you a background on their features and which will best suit your needs.

When the temperature outside begins to climb, many people seek the cool comfort of indoor air conditioning. One type that we see all the time is the window air conditioner. Window air conditioners are an easy and economical way to cool a small area. Air conditioners come in various sizes, cooling capacities and prices. Most businesses and office buildings have condensing units on their roofs.

Air conditioners are one of those things that we see every day but seldom pay much attention to. An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling.

Air conditioners remove both heat and humidity from the air. If the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.

Room air conditioners are rated by their energy efficiency ratio EER, which is the cooling output divided by the power consumption. The higher the EER, the more efficient the air conditioner.

Portable air conditioners are not as effective as window ac units yet, and only recommend these when a window unit does not fit into a window such as casement or slide-out styles. Many people buy an air conditioner that is too large, thinking it will provider better cooling. However, an oversized air conditioner is actually less effective – and wastes energy at the same time.
