air purifiers

There will always be ozone critics and rightly so. In a "HIGH" concentration, ozone is very irritating and can even be unhealthy.

Water is also a problem when its concentration is too high. It causes death by drowning, mudslides, property damage, and disruption of public and private activities. Ingesting too much water at one time can be poisonous. Fire fits into the same category. We need fire for all of its practical benefits but we hate it when it attacks our forests and homes. Sunlight has good and bad extremes, as well.

Ozone is now known to be natures most powerful disinfectant and oxidant and can even kill microbial contaminates like E-coli, Candida, Listeria, Staph, Salmonella, Giardia and Cryptosporidium more effectively than dangerous conventional disinfectants like chlorine or bleach. In fact, ozone kills E-coli more than 3,000 times faster than chlorine.

When ozone is created, it seeps into crevices, carpets, drapes, furniture, under beds, in closets, on counter top surfaces and other places where normal air currents are minimal or even non-existent.

When the extra oxygen atom splits off from the ozone molecule, two things happen: disinfection and oxidation. This happens as these atoms quickly destroy the bacteria, mold, mildew and odor as soon as they come into contact. The end result is clean breathable oxygen.

Air Purification, Water Purification, Deodorization, and Food Sanitation

This is a tough question. We think 90% is easily obtainable with high quality air purifiers, air cleaners, filters, and good practice. This may not be enough and you may want to push the limit. Average counts in the 10 to 20 range on the DC1100 are possible. The air quality throughout the home will vary significantly, but we believe average readings in the 10 to 20 range are possible which, if the outdoor ambient is 500, results in a 96 to 98% reduction in particles within the detection range.

Actually the preferred method of rating air purifiers is the CADR which is based on how fast the air cleaner or air purifier cleans the air in a sealed room. This is a useful rating for comparing one air cleaner to another. The problem with this concept is that we don't live in sealed rooms. The truth is that you cannot predict how clean the air will be in your house based solely on the CADR. Nobody's home is perfectly sealed, doors open and close, and particles are generated by virtually any activity within the house. So, the number of particles floating in your home air is the result of a constantly shifting balance between particles entering the home, being generated within the home, natural settling, and active removal by air cleaning devices.

Yes. With the DC1100 you will know the actual number of particles suspended in the air within the units detection range. The numbers displayed are scaled to correspond to approximately what a 12 year old would inhale with each breath. If the counts drop from 600 to say 60 then you know that you have reduced the detected particulate pollution by 90%. How much a reduction you see corresponds to the effectiveness of your air purifiers and air cleaners.
