This may be true, BUT they also may need odor deodorization and bacterial sterilization so that the air is naturally fresher because the source of the odor has been retarded.

Whole House In Duct Air Purifiers If you are looking for a WHOLE HOUSE air purifier realize that there is NO tabletop unit, of ANY BRAND that can accomplish this task. ONLY a unit that fires ozone into the air ducts,  like the Air-Duct 2000 can evenly distribute ozone throughout the ENTIRE home. Ozone or ions cannot pass through walls. Whole House In Duct Ozone Generator  Air-Duct 2000 The Air-Duct 2000 can purify the air in an entire home because it fires ozone directly into your air handling system. It can purify the air and removes odors In entire homes, offices, restaurants, and bars. Built in Burst Timer for air purification in small or large areas. Totally Automatic Operation CLICK HERE to learn more about the Air-Duct 2000!

Ozone will begin by having a fresh, sweet, rain type odor. This is the level recommended for air purification.

There is no reason to turn the ozone level higher at this point. If too much ozone is present the air will begin to have a bleachy, chlorine smell. If it begins to smell like that it means that the ozone level is set to high for air purification and should be at a lower ozone setting. 

If the odor returns or you want to make the air smell fresh again turn the ozone generator back on it's lowest level.

When ozone is used for air purification it need to be constantly monitored so that the level does not get too high. This is known when the ozone gets the "bleachy smell".
There are some instances in which the lowest ozone setting can be chosen, and the unit may be run continuously. But realize that the ozone level may reach an annoying level fairly quickly and the unit turned down or off. All our units are very strong.

The recommended levels of ozone for air purification are between  0.01 parts per million & 0.05 ppm. The nose begins to detect the "sweet smell" of ozone around 0.01ppm. So as long as you do not let the "fresh smell" turn in to the "bleachy smell" it is generally accepted that the ozone level is within recommended safe levels.

If there are still concerns about the ozone level being acceptable, a portable ozone meter such as the the EZ-1X Ozone Sensor will monitor ozone levels in occupied spaces.  It can be used to monitor ozone levels in a home, restaurant, bar, or in any other space where ozone is meant to be kept at recommended level around humans & animals. It constantly monitors ozone levels by displaying them on a multi colored bar graph. The green,  yellow, &  red bar graph is easy to read and is easy to understand by non technical personnel.

With a true high powered ozone generator you can SHOCK TREAT unoccupied rooms to kill bacteria, and mold in specific sized rooms.

Ozone naturally decays back to oxygen in about 30 minutes to an hour. Because of that fact an under powered machine will not have the ability to develop a high enough ozone concentration in an area to kill bacteria. Ozone is constantly reverting back to oxygen so that it may never have a chance to build to an effective parts per million level to do much good.

The best ozone generator for a normal sized room is the XT-400 or the XT-800 because the user has the most possible control over the ozone level.  With it's ozone burst level settings from 2, 5, 10, 20, 25, 30, 40, 50, or 60 seconds per minute it can achieve very low ozone levels when needed.  The included remote control allows the user the ability to turn the ozone level down, or the unit off, before the ozone level rises to an irritating level.

The XT-800 is also a great unit because it comes with a "Half Power Switch" that can turn an XT-800 into an XT-400 instantly!

It is the total ozone output in milligrams per hour that counts! Please CLICK HERE for ozone generator sizing considerations.     Mold-Kill sells only Air-Zone® brand ozone generators. Old style ozone "plates" may create large amounts of  Nitrogen Oxides which are offensive, irritating, and dangerous. Air-Zone's patented ozone elements are in a permanently molded housing, that require NO adjustment whatsoever.  They also do not produce any measurable amounts of Nitrogen Oxides. Our elements use 24 carat gold plating on our elements internal components to help prevent corrosion.  The use of high temperature, shatter resistant tempered glass is also incorporated in our innovative U.S. Patented ozone elements. Old style ozone "plates" consist of flimsy easily corroded steel screens and delicate thin pieces of glass or mica which must ALWAYS be in perfect alignment. We do not use MICA ozone plates in our ozone generators. MICA is the cheapest and worst material to use in an ozone plate.  MICA easily breaks, flakes apart, burns, and shorts out the generator.  Stay far away from any ozone generator using a MICA ozone plate. Click Here to learn why our US patented ozone elements are far superior than "old style" mica ozone plates. If not cleaned and aligned constantly, old style ozone "plates" will produce less ozone, and possibly even spark out dangerous high voltage electricity. Air-Zone's® patented ozone elements solve all these problems. Old style ozone "plates", first designed in the 1800's,  must be removed, scrubbed clean, dried, and be meticulously reassembled, or they will not work correctly. Even with all that work, their life span is notoriously short. Air-Zone's® low cost, patented ozone elements can be quickly cleaned with the special included element cleaning tool we include with every ozone generator.  They can be replaced in minutes with a screwdriver. Old style mica ozone "plates" consist of 4 separate parts. Each of the 40 pieces in A 10,000 mg/hr ozone generator must be meticulously installed and aligned for the ozone machine to work properly. Our corona discharge elements work much better than UV Ultraviolet bulbs.  General Electric, the manufacturer or UV bulbs, states that ultraviolet light does not kill mold. Air-Zone® U.S. PATENTED Ozone Elements   We DON'T use cheap, outdated MICA ozone plates like these: Why use outdated  100+ year old ozone plate technology when  Air-Zone® has the patented the no adjustment necessary ozone element?!! The Countdown Timer runs the machine for  10, 20, 30, minutes, or up to 2 1/2 hours and then it shuts the unit off. The Continuous mode allows for longer, or overnight applications.  It's smart chip remembers the timer setting last set even if the unit is unplugged!
