Buyer's Guide

Air Purifier of Choice. Buyer's Guide.
Choosing the right air purifier is the important even. 
The decision you make will greatly affect the benefits you and your family get from utilization of this unit. This also affects whether or not you'll get rid off your air quality problems and breath clean and pure air.
So, do it wisely.
There are few things of greater importance you should consider when choosing the right air purifier.
They are:
1. the air quality problem you are trying to get rid of, such as: dust, pollen, ciagerette smoke, odor or chemical problems, mold spores, per dander, etc. 
2. the size of the cleaning area in square foot;
3. the number of complete air changes per hour;
4. filters lifetime;
5. power consumption;
6. possible off gassing the unit might produce;
7. level of noise produced;
8. warranty.
The following guide and tools will help you determine the best model for your particular air cleaning needs.
The table below will help you select the most effective units for your particular air cleaning needs or air quality problem 
The maximum cleaning area and the size of your cleaning area.
Ones the air quality probelm is determined and you know what air filtration system should provide you with the best cleaning result, it's time to find our whether or not the unit we intend to purchase can handle the size of your area or more presisely, the volume of air in your cleaning area.
Please note, the maximum cleaning area is normally provided for the room with the average height of the ceiling ( 8 feet) in which the air cleaning device (air purifier) operating on the highest setting (speed) provides two(!) complete air changed per hour.
Two complete air changes per hour is enough to make the difference in the air quality noticeable.
Meanwhile, if you wish to get a truly clean and healthy air under normal residential or office conditions, it requires at least 5 air changes per hour.
The cleaning area size calculator below will help you to determine the maximum cleaning are for any height of the ceiling and the number of complete air changes per hour.

Worried about the radon problems. The Model(s) of Choice
The EPA ranks indoor radon among the most serious environmental health problems facing us today. After smoking, it is the second leading cause of lung cancer in the United States. Radon is a naturally occurring gas that seeps into buildings from the surrounding soil. Radon gas decays into radioactive particles that can get trapped in your lungs when you breathe. As these particles break down, they release small bursts of energy. This can damage lung tissue and lead to lung cancer over the course of your lifetime. 
While there is no effective way to get rid of radon except for exhaust procedure, large amount of specialty enhanced impregnated granular carbon can be effectively used for removal chemical substances produced in result of reaction radon with the air.
