Frequently Asked Questions

Simply put, UV air purifiers use ultraviolet light rather than only material filters. This means that they are able to effect air pollutant particles that regular filters will often miss. Hospitals and other establishments that rely on a high standard of air quality use this type of filtration system because it is effective in eliminating microscopic air pollutants such as viruses, bacteria, and mould.

UV air purifiers require regular maintenance checks – at least once a year – just as any other home air filtration system. They also require the material filters to be changed regularly.

Please ensure that all potential work areas are free and clear of any obstacles, including your furnace room. The more readily accessible your home is, the faster the installation will be. Also clear any pathways to work areas of tripping hazards.
