Air Filters - Everything You Need To Know About Air Filters

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.

Do You Need an Air-Purifier in Your Home?

Air purifiers have been around since the Second World War, when the first ever HEPA filters were used to protect workers from airborne nuclear matter. Today air-purifiers are found in hospitals, homes, offices and even in cars. We’ve been breathing the same air for the last hundreds of years then why do we now need air-purifiers, that too indoors? Aren’t our homes our refuge from the pollution, smog, chemical waste, pollen and all other toxins found in the outdoor air?

You’ll be surprised to know that the answer to that is no. According to the U.S. Environmental Protection Agency, levels of indoor air pollution can be two to five times higher than those found in the urban outdoor air! Did you know that indoor air pollution is rated amongst the top five environmental risks to public health? We spend more than 90% of our time indoors – in our homes, offices and schools. It logically follows that our indoor spaces can be a hotbed for viral infections, allergies and respiratory disorders arising due to indoor air contamination.

So, what kind of indoor air pollutants are we talking about? The contaminants in our homes are of many types. They range from dust, mold, bacteria, pet dander, fumes and carbon deposits from fireplaces and candles, toxic odors from tobacco smoke, dust, mites, deleterious vapors from furniture and flooring, and household chemicals. And inhaling these can give rise to allergies, asthma and other respiratory ailments.

How will YOU know if you need an air purifier?
You can benefit from having an air-purifier in your home if you observe allergic symptoms like itchy, watery eyes or a runny nose, frequent skin rashes. If you suffer from asthma or any other respiratory disorder you would gain from having an air-purifier. If you live with a smoker, an air-purifier will help to eliminate suspended tobacco smoke and odor from the air. Pet owners will stand to benefit as air-purifiers are able to effectively deal with pet dander and smells. If you detect mold or mildew in your home you should consider investing in an air-purifier system.

However, not all air-purifiers will be able to clear all the contaminants. While all will clean certain elements there are differences in the abilities of each air-purifier. Some are able to remove dust mites and pet hair and smoke effectively, while other attack types of bacteria, viruses, mold and mildew. Few will be able to tackle all of these things.

Filterless Air Purifiers: What You Need To Know

As the importance of healthy living conditions assumes greater proportions, air purifiers and air cleaners have started to become an integral part of millions of households. And quietly rising in prominence among air purifiers is a special type called the filterless air purifier – a testimony to the advances that have been made in this field. Like the name suggests filterless air purifiers clean or purify the air without the help of a filter and are effective in removing particulate matter that typically cause allergy symptoms. Let’s try and now gain an informed insight into the world of filterless air purifiers.

Filterless air purifiers are functionally strong in terms of removing particulate matter such as dust, mold spores, pollen or pollen-like grains and other similar-sized particles from the ambient air. A point to note here is that while popular types of filterless air purifiers carry a carbon sheet to absorb unfriendly odors, its not a recommended option for people who are hypersensitive to chemical particles (MCS – Multiple chemical sensitivity sufferers) or people who suffer from asthma. That is to mean that physical absorption is a sure strength of these filterless air purifiers but the same cant be said about chemical absorption.

So what makes the filterless air purifier different from your regular air purifier? Fundamentally, it’s the way the unit works: Inside the filterless unit are a set of two plates that are electrically active much like the plates of a capacitor. The function of the first plate of the filterless air purifier is to charge the particles in the airflow and that of the second plate is to absorb the particles that have been charged by the first place through electrostatic attraction. As you might have guessed, the actual number of moving parts in this kind of an operating unit is low and hence there is lesser wear and tear of the filterless air purifier and also a lesser operating noise. The only pain point if any at all of this marvelous system is that the plates need to be washed regularly to achieve maximum efficiency.

As you can see filterless air purifiers make an obvious choice for the function-conscious user desirous of procuring a value-for-money product. Experience the effect of this air purifier and open the doors to a future that’s a whole lot healthier than ever in your past. Here is to a happy healthy life!!

The History of Pressure Washer

Pressure washers have been around for many years. There have been changes made to the washer itself that have made it more popular over the years. Some of the first pressure washers were created and first used toward the end of the 1960’s and in the 1970’s. At this time however, pressure washers did not have the same power as they do today. Also they did not do the same variety of jobs as today’s pressure washers. It was because of the limited functions of the pressure washer that many people were not interested in buying it.

Over the years more and more people were using pressure washers. After several change we have the pressure washer that you see today. The pressure washers that are being sold today can be found in hardware stores. There are certain hardware stores however that sell only a certain brand name of washer. Certain brand names of pressure washers are better than others and this is something you should keep in mind when buying a pressure washer. If you are not sure of what type of washer you need then it is always a good idea to ask a customer service representative before you make your purchase. By telling this person what you need the washer for they will be able to find the one that is right for you.

Pressure washers are used for a variety of things. The most common use of a pressure washer is to clean the leaves out of the gutter of your house. Due to the intense pressure behind the water, the leaves can be easily removed by the water. Most pressure washers have extensions and you can easily reach the gutters. Another thing that they are used for is washing windows. Some pressure washers have compartments where you can fill them with detergent. When you turn on the pressure washer and spray the windows you are also spraying some form of cleaning agent onto the window. With the pressure behind your water you can clean you windows quickly and easily.

Home Heating Choosing a New Furnace

As winter approaches, everyone begins to think about the furnace. Will in kick on? Will it last through another long, cold winter? Should we install a new furnace? If so, with what kind? If these questions are familiar to you, keep reading as we try to "demystify" a couple of household heating sources.

The most important step to take before starting the furnace for the season is to have it inspected by a licensed professional. They will clean the furnace, make sure it is in good working order, they will also recommend any parts that will need to be serviced or replaced in the near future.

If the furnace inspector tells you that it is time to replace the furnace, you may be overwhelmed by the choices in today’s’ furnace market. There are the standard gas, oil and electric furnaces as well as the newer outdoor wood furnaces and corn-fueled furnaces to name a few. There is lots of information available on these newer furnaces on the internet, however, a quick overview will be provided here.

One of the most popular options today is an outdoor heating source. It uses the old standby of wood, but eliminates the mess and smell associated with burning wood. An outdoor wood heating unit is placed approximately 500ft from the house. The wood burner itself is built inside of a small building, this often is made to look like a smaller house or shed. The heat is carried from the burner via heated water, which runs through underground, insulated pipes. This is the most effective and efficient method for moving heat over distances. Once the heated water reaches its destination, there are a couple of options for actually heating the home. Using a boiler, radiant floor heating system, a heat exchanger or a forced air furnace that is powered by a direct circulation system. The wood burning system can also do double duty to heat household water if a water-to-water heat exchanger is installed.

Although there are many advantages to using an outside wood burning furnace, it has a down side to its use as well. The cost can be quite high for most people, running approximately $5,000 installed. This of course, depends upon what part of the country you live in.

Another alternative to the traditional furnace that is gaining in popularity is the corn burning furnace. This type of furnace uses shelled corn (the same kind fed to livestock) to heat a home. While this is a viable source of heat it is not fool proof, it does have drawbacks that need to be considered before making a final decision.

Corn fuel furnaces are comparable to a convention furnace as far as price is concerned, costing roughly $2,000. It uses corn that has no more than 15% moisture content; fortunately, this is the same percentage of moisture as feed corn, making it very easy to obtain from a local elevator. The cost of burning corn as compared to propane is approximately one bushel of corn is to 5.5 gallons of propane fuel. Corn is also a natural and renewable resource, and keeps farmers in business while keeping your heating costs down.

On the other side, corn fed furnaces need daily cleaning to be efficient. They also run on an electric fan system, if you lose electricity, you lose heat also. For this reason, its best to either have a generator or a back up furnace for emergencies.

Being armed with the knowledge of these types of heating sources will make you a more educated consumer when it is time to replace an old, worn out furnace.

Furnace Buying Tips

Choosing a furnace for your home is not difficult. The following list are features that you may want to look for when buying your furnace.
1. What type of furnace do you want? Will it be Gas or Electric?
The Gas Furnace
The gas furnace is always more affordable to use than the electric furnace where gas is readily available. On the downside, burning fuel generates fumes. In well-maintained gas furnaces, the fumes generated are enclosed in the exchanger and then exit the house through an exhaust vent.
Remember, a gas furnace must be checked by a qualified professional at least once a year. The professional would check the furnace for holes, leaks or cracks. A break or crack in the furnace lets carbon monoxide seep into your house or place of business.
The Electric Furnace
The electric furnace has a higher cost than a gas furnace. On the upside, since electric furnaces do not use flames, it does not generate any carbon monoxide. The electric furnace is cleaner and safer than a gas furnace.
2. The Quality of the Furnace
The quality of the furnace determines how long and how well it will perform. Choosing a brand of furnace that has a history of quality and reliability can be less costly in the long run. Ask your contractor about which brand will be optimal for your needs. A free estimate for the purchase and installation are available in some companies.
3. The Efficiency of the Furnace
The efficiency of gas furnaces are determined by the AFUE or Annual Fuel Utilization Efficiency ratings. The AFUE ratings identifies how efficiently is the fuel being consumed. In most cases, a higher AFUE rating means it takes less fuel to heat your home.
Gas furnaces with higher ratings cost more than those with lower ratings but may save you more money down the road. A minimum rating of 78% is established by the government in 1992. Many furnaces have an efficiency rating of about 60% prior to 1992.
a. The Mid-Efficiency Furnaces
The mid-efficiency furnaces are also called ‘induces draft furnaces’ or ‘non-condensing furnaces’. The mid-efficiency furnace offers the bare minimum of 78% efficiency up to about 80%.
b. The High-Efficiency Furnaces
The high-efficiency furnaces are also known as ‘condensing furnaces’ or ‘sealed combustion furnaces’. The high-efficiency furnaces has an AFUE rating as high as 96%. Some furnaces use a two-stage valve and an efficient variable-speed motor to raise comfort and effectiveness.
4. The Comfort features of furnaces
Several furnaces provide features that increases comfort and efficiency.
a. The features of the two-speed furnace
The furnace can function at low speed for most of the time. It allows for a more quieter operation for a longer amount of time compared to a ‘single-speed furnace’. The longer run periods allow for fewer start/stop cycles, less drafts, and very little temperature variance.
The temperature swing is limited to about two degrees compared to the four degree variance of the single-speed units. The two-speed unit gives better circulation which prevents warmer air from rising and the cooler air from settling down. The two-speed unit gives a more consistent temperature in the house.
b. The features of variable-capacity furnaces
Furnaces with variable capacity provide a combination of efficiency and comfort. The variable-capacity has a motor that regulates your needs by automatically adjusting air volume and speed. The var-cap furnace provides the most efficient heating and cooling.
A fan comes with the var-cap furnace. The fan will reduce your cost during summer. If the fan is used throughout summer, the central air conditioning unit increases in efficiency.
5. The furnace noise level
Unfortunately, all furnaces do not come with a standard rating system for sound unlike heat pumps and air conditioners. Although, two-speed units and var-cap units generally operate at a low noise levels.
The two-speed and var-cap furnaces run for longer periods and lower sounds than the standard unit. Certain var-cap units has features that prevent ‘creaking’ of the ducts due to expansion and contraction caused by changing temperature. The temperature differential is reduced so that the creaking noise is also almost eliminated.
