When it comes to dealing with mold or tobacco odors, you can’t just use a typical air purifier for complete elimination.

If you want to get rid of the smell at its source, then you’ll need an ozone generator. In this case, a high-quality unit like the OdorFree Villa 3000 ozone generator can be a great option, especially since it comes from a reputable manufacturer.

This one-of-a-kind ozone generator is by far one of the best in its class. The Villa 3000 removes odors from the air using powerful ozone technology, using a highly effective activated carbon filter to eliminate VOCs and other pollutants.

Frequently Asked Questions (FAQ)

Who makes the best ozone generator?

There are many brands that make ozone generators, and the most popular brand right now is Everpure. They sell Ozone generators that can be used for household water purification, as well as air purifiers.

As an air purifier, ozone generators operate by raising oxygen levels in the atmosphere. Increases in oxygen are known to have positive effects on the respiratory system, and they also can serve to sanitize air. Ozone generators have the ability to remove allergens, odors, as well as other pollutants.

Are ozone generators any good?

Ozone generators are great for cleaning odors and removing harmful chemicals from the air in your home. They work by breaking down and separating molecules and particles so that they can be filtered out more easily. Ozone is a natural antiseptic which can rid your home of mold and viruses, among other nasty things, making the air you breathe cleaner and healthier.

How long do ozone generators last?

The lifespans of ozone generators are quite variable. You probably won’t be surprised to learn that the life of an ozone generator depends on how much you use it, how hard it is used, and what the operating conditions are. Overall, ozone generators have a lifespan of between 1 and 2 years, on average.

When they reach the end of their lifespans, these generators require a lot of maintenance, including cleaning and filter changes. Theoretically, you can keep your generator for a lot longer if you take care of it and keep it in optimal operating conditions.

Do ozone generators really work to remove odors?

There is a lot of debate over whether ozone generators actually work. Ozone itself is actually a pretty strong disinfectant, and it will also destroy some natural odors. At the same time, it can be detrimental to humans and pets in high amounts.

However, most ozone generators are not strong enough to rid a home of mold and mildew or other similar problems. They are great for disinfecting your home and addressing mildew, but may not be enough if you have significant problems.
