However, it's important to note that ozone generators like this one should only be used in unoccupied spaces due to safety concerns. The product's strong customer support, along with a 5-year warranty and a 30-day money-back guarantee, adds peace of mind for buyers. Additionally, it’s not available for sale in California due to state regulations on ozone products.

However, it's essential to note that this product is not available for sale in California due to Amazon’s policy on ozone products.

On the downside, the product's use is restricted to unoccupied spaces only, due to the nature of ozone. While this is a common limitation for ozone generators, it does mean that areas need to be cleared before use, which might not always be practical. Also, potential buyers in California should note that Amazon's policy prohibits the sale of ozone products in the state.
