Air Purifier Installation for St. Thomas Homes
Platinum Air Care offers a range of air purification solutions tailored to the needs of St. Thomas-area homes. Our recommendations are based on factors such as home layout, existing HVAC systems, and individual air quality goals to ensure each solution fits the household.
Solutions may include high-efficiency particulate filtration, whole-home air purification systems integrated with ductwork, and portable all-in-one air purifiers that need no ductwork. Each system is selected to support cleaner indoor air while working reliably with your home’s heating and cooling system.
Portable · no ductwork needed
Portable all-in-one air purifiers
Everything in one cabinet — prefilter, HEPA, carbon, and UV-C + PCO — so one unit covers most homes on its own. Move it to whichever room needs it most.
Whole-home · out of sight
Whole-home HEPA filtration
Fitted at the furnace and out of sight, it treats the air before it is redistributed through the house. Filtration catches particles as the air passes through it.
Whole-home · UV-C + PCO
UV air purifiers
UV-C and PCO treat what a filter cannot catch — odors and airborne contaminants. They work whenever the furnace fan runs.
