Frequently Asked Questions

A UV air purification system is different from regular systems because it uses ultraviolet light to filter air. This means that it can capture particles that regular material filters may miss. Often, hospitals and food processing plants will use UV air purification for thoroughly clean air because they can help to eliminate air pollutants such as bacteria, viruses, and other microorganisms.

UV air purification systems should undergo a routine maintenance check – about once a year – along with the rest of your home comfort system. They also require regular filter changes just like any other air cleaning products.

Please remove any potential tripping hazards from all pathways to potential work areas, including your entrance way and stairs or hallways. Also have your furnace room along with any other potential work areas readily accessible.

Our expert technicians usually complete UV air purifier installations within 1 to 3 hours. This may vary depending on factors such as how readily accessible the work areas are, but rarely will an installation take longer than 3 hours, if that.
