The Estate 4000 is designed for the largest spaces and strongest odors in homes, condos, and offices. This model has a variable ozone-output control and a 12-Hour Timer that turns off automatically when the sanitizing is completed. For deeply entrenched odors, there is also a “Hold” setting for treatment longer than 12 hours until the machine is turned off manually.

A good selection for large houses, large condos, large offices, rental properties, fitness centers, restaurants, smoking bars, casinos, commercial applications, bingo parlors, pool halls, and large yachts. Treats odors such as cigarette smoke, mold and mildew and pet odors. Click to learn about treating the odors in your location. Select Your Odor


  • The larger the space, the longer the treatment time
  • The heavier the odors, the longer the treatment time
  • Odors normally migrate throughout the facility
  • Treating the entire space including ductwork is most effective

Comes complete with plates and a filter. These are designed for long-term use and can easily be cleaned and reinstalled. Just plug in the unit, turn the dials to select time and output level. Then vacate the area while the odors are oxidized.

Warning: For use in unoccupied spaces only. Prolonged exposure to high ozone levels can cause eye and respiratory irritation. Anyone with respiratory issues should consult their physician before use.

+Operating Instructions+

  1. Close all outside doors and windows of the area to be treated.
  2. Make sure inside doors, such as bathroom and closet doors, are open.
  3. Set thermostat to maintain a moderate temperature in the facility to be treated. Fan may be turned to "On" to circulate ozone throughout the space.
  4. Make certain all occupants and pets have been removed.
  5. The Ozone Output dial is normally set at "Medium" to "High" depending on the level of odors and amount of time for treatment.
  6. Set Timer to desired treatment time and then exit the space during treatment.
  7. Upon returning, make sure Timer dial is in the "Off" position.
  8. Allow 1 to 2 hours after treatment before re-occupying the space, or open the outside windows and doors upon reentry.

Note: A higher Ozone Output setting will sanitize the space more quickly. The amount of time necessary to eliminate pollutants depends on how entrenched the odors are. The effect of ozone will vary depending on environmental conditions such as temperature, humidity, size of the space, contents of the space and the severity of the odors.

Hold Position: For more severe odor problems, turn timer dial to the "Hold" position and vacate the space. This will allow for longer sanitization and will produce ozone until generator is turned off manually. Upon return, turn the dial to "Off" and open outside windows and doors. Vacate area until sanitization smell is gone.

Warning: For use in unoccupied spaces only. Excess ozone concentrations can cause mucous membrane and respiratory irritation. If you detect the sanitizing smell when you walk into the room, make sure the Timer dial is "Off" and then ventilate the area or vacate the room.

Odor Free Estate 4000 Testimonials

Rooms in our extended-stay facility regularly build up odors from pets and smokers. They also have kitchenettes so cooking odors are an issue too. The Odor Free takes care of just about any odor problem that is left behind by our guests. We recently used the ozone generator to get rid of the smell of marijuana in one of the rooms and it worked great!

Our trucking company has a fleet of tractor-trailers with sleeper cabs. The odors in the cab really build up after being operated by the same driver for a long time. There are not only food and body odors, but the cabs are often smoked in as well. When a driver moves out, we clean up the truck and then fumigate with the Odor Free. This ozone generator does just what we wanted it for, and our new driver gets a clean smelling cab. A couple of our drivers have taken it home to get rid of odors and make their house smell better. If anybody wants to know how well it works tell them to give me a call.

We use the Odor Free on car odors at the dealership every day. It removes any pet or smoking odors after we detail the car. For a fairly new vehicle, a 10 to 20 minute ozone treatment will get it back to smelling like a new car again. On a used car with a strong smoke smell, we may need to run it for a several hours. With the odor gone we can put the car on the lot for sale.
