Indoor pollutants are a serious concern because most people spend as much as 90 percent of their time indoors. The U. S. Environmental Protection Agency (EPA) studies of human exposure to air pollution indicate that indoor levels of many pollutants may be two to five times and occasionally more than 100 times higher than outdoor levels.
Clean air is not only important to your health it is also important to your general well being. The smell of fresh air is stimulating and invigorating for the mind and your mental state.
Breathe pure air – An air purifier will dramatically improve the climate in your home or in the office. Especially if you are not enforcing a strict non-smoking policy and you regularly have smoking guests or if a member of your family smokes an air purifier is invaluable.
Some Air Purifiers come with with ionizer and fragrance dispenser – For me the ability to spice up the climate in my home with exotic fragrances is such a gift. Think about it – Our sense of smell is more probably one of the most underrated in our culture today – We visit fancy restaurants to satisfy our sense of taste – we go to concerts to satisfy our sense of sound. We travel to foreign countries to see mountains and other wonders of nature- but rarely do we do something specifically to satisfy our sense of smell. And that is a shame since it is such a huge and important part of our daily life.
Types of air purifiers
There are a few general types of air purifiers and making some distinction will help you make an easier decision. Always when buying new home equipment it’s always a good idea to ask yourself what your actual need is. Why am I buying this equipment? Keep that in mind and use that to filter out some of the sales bogus. By the way, the Internet is a great resource when it comes to air purifiers. You can gather alot of useful information and safely buy the equipment when/if you decide to do so.
Below we have made a short guide the different kinds of air purifiers:
1. Carbon air filter purifiers (removes odors)
Carbon is an active material used for many things in science and a few things in everyday life. It has one great advantage in concern to air filters and air purification, namely that it’s extremly active. By active is meant active in the chemical sense and in a way that makes it react with many types of small particles in the air. Carbon air purifiers will remove some of the odors from the air in your home and odor removal is the main purpose of this type if air filter. If you don’t have problems with odors in your home there will be little point in aquiring carbon air fiters.
A downside to carbon air filters is that they won’t last forever. The air filter in the air purifier itself will have to be replaced regulary. And for your information, they will not absorb carbon monoxide or other dangerous gaseous pollutants in the home. But if you have suspecion about high density of dangerous pollutans you are probably better off locating and taking care of the sources of these rather than getting an air purifier.
2. Electrostatic Air Purifiers
The electrostatic air purifiers remove particles from the environmental air. Particles such as fine animal hair that circulates in the air, some sizes of dust particles and other elements that will be caught by the electrostatic charge in the filter.
Technically speaking, the filter works by applying an electronic field across the filter/electrostatic plates and thereby attracting particles that can be charged – which most can. The good thing about this air filter type is that you do not need to change it, only clean it.
What will the electrostatic air purifier remove?
- Plant and mold spores
- Mildew and fungus
- Animal dander (not as effective as the carbon air filter though)
- Paint and carpet fumes
- Flooring adhesive fumes
- Cleaning products fumes
Electrostatic air purifiers are effective when it comes to reducing airborne allergens, such as for example pollens. It has come to our attention that some physicians recommend electrostatic air filters, electrostatic furnace filters and electrostatic air cleaners for indoor airborne allergy prevention. If you have personal experience with this, we’d like to hear from you.
3. HEPA Air Purifiers
HEPA stands for High Efficiency Particle Arresting. This is the best and most efficient type of air purification.. The high effictive particulate arrestors (HEPA) are capable of taking out even some of the smallest particulates in the air. Again this is an interesting feature for allergics and who have polluted air in their home.
HEPA Filters were developed by the Atomic Energy Commission during the second world war to remove radioactive dust. HEPA filters are today used in many professional relations: They are used to clean rooms where sensitive electronis are developed, hospital surgery rooms, bio-engineering, pharmaceutical processes, and any application where reduction or removal of very small particles is required. HEPA air purifiers cleans the air 99.97% of all particles including bacteria, fungal and other microbiological organisms.
The HEPA air purifier has a filter made up of millions of small glass fibers which the air has to pass. These tiny fibers will collect the particles and the HEPA filter will actually become more efficient over time as particles fills out the passages in the filter making it even more “dense”.
The HEPA aircleaners typically will have a life time from two to four years after which they will have to be exchanged. If you want a smoke removing filter, the HEPA air purifier system will not do the job…although you can get optional additions to your system that will enable both the HEPA function and the smoke removing ability.
Because of the HEPA’s high filtration capability, this filter type is usually regarded the best in terms of removing allergenes.
