If you have a large space or want to cover multiple areas, you might need several units. The recommended lifespan of 7 years means you'll need to plan for replacements, especially if you’re not keen on monitoring the date closely. Additionally, while the unit is UL Listed, users should ensure that it's placed in appropriate locations as specified in the installation guidelines for optimal effectiveness.
