Air purification · London & Southwestern Ontario
Medical-grade air purifiers for your home or business
Two ways to get there. A portable all-in-one unit — prefilter, HEPA, carbon, and a UV-C + PCO chamber in one cabinet — or a whole-home system fitted into your furnace ductwork and out of sight, installed in Ontario homes since 1999.

Portable · no ductwork needed
Portable air purifiers
Everything in one cabinet — prefilter, HEPA, carbon, and UV-C + PCO — covering most homes on its own and used in thousands of medical and commercial environments. Move it to whichever room needs it most.
A portable makes sense when…
- You are in an apartment or condo with no ductwork
- One or two rooms are the problem — a bedroom, a home office
- You want to move it to whichever room is being used
- You already have a whole-home system and want more in one room
- A dental office or treatment room needs a set number of air changes per hour
- Wildfire smoke season — nothing to install, and it works the same day
Whole-home · out of sight
Whole-home HEPA and UV air purifiers for your furnace
Fitted at the furnace and out of sight, it treats the air before it is redistributed through the house — rather than one room at a time. It works whenever the furnace fan runs, and the fan can be set to a low continuous speed so that air keeps passing through it between heating and cooling cycles.
A whole-home system makes sense when…
- You have forced-air heating and cooling
- The house is on more than one level and shares ductwork
- Someone in the house has allergies or reacts to what is in the air
- The house is sealed up tight through the winter
- You want the same air everywhere, not room by room
- You would rather not see the equipment at all
Two different jobs. Filtration catches particles as the air passes through it. UV-C and PCO treat what a filter cannot catch — odors and airborne contaminants. A home that wants both ends up with one of each, which is the trade-off against a portable: the MedicAir® Pro does both jobs in one cabinet, but sits in the room.

ActivePure® and active air purification
Filtration waits for the air to come to it. Active air purification works the other way around — it treats the air and the surfaces in the room, rather than only what passes through a filter. ActivePure® is the technology behind the Aerus line, and Platinum Air Care is an authorized dealer. The Beyond Guardian Air and Guardian Air Home use the ActivePure® technology.
How active air purification worksNot sure?
Active purification is usually added alongside filtration, not instead of it. Which combination suits the house depends on the layout and how the air actually moves through it.

Ventilation and commercial air purification
Two more things we do that sit alongside purification rather than inside it.
Ventilation: HRV & ERV
Purification cleans the air you have. Ventilation brings fresh air in and stale air out, without throwing away the heat. Cores, filters, and the intake and exhaust runs are all serviceable.
Our HRV/ERV technical guide is cited as a reference in Harvard Graduate School of Design research published in Sustainability (2025).
HRV vs ERV: what’s the differenceCommercial air purification
The same equipment we put in family homes is in dental offices, care homes, salons, universities, and more. Sized for the room and the occupancy, not the square footage alone.

Common questions about air purifiers
What is a medical-grade air purifier?
The term describes the level of filtration, not a certification. It means true HEPA — the same filter grade used in clinical settings, usually combined with carbon for odors and a UV-C PCO stage. Our portable and duct-mounted units are built to that standard, which is why the same equipment ends up in dental offices and care homes as well as houses.
Will an air purifier help with allergies?
It removes the dust, dander, and pollen the system would otherwise keep moving through the house. Those are the things most people react to, so less of it in the air can only help.
How much does an air purifier cost?
It depends on the equipment and on the house — a portable and a duct-mounted install are not the same job, and what suits one home is wrong for the next. That is what the air quality test is for, and it costs nothing through Platinum Air Care.
Do I need a portable or whole-home system?
Preference, mostly — one is not the upgrade of the other. Duct-mounted stays out of sight and reaches everywhere the ducts do. A portable puts the purification where you actually are, which is the fastest way to change the air in the room you are in, and you can move it. Plenty of homes run both, and more than one portable is common. The MedicAir covers most homes up to around 2,500 sq ft on its own; the air changes per hour calculator will size a room for you.
Does a whole-home system only work when the furnace is running?
It works whenever the furnace fan runs, or when the fan is set to a low continuous speed, so air keeps passing through between heating and cooling cycles rather than only during them.
Do you service units you do not sell?
Often, yes. We still supply filters, UV-C lamps, and parts for many brands, including RespirAide, Saviair, and more. Tell us your model, and we will see if we can help.
What areas do you serve?
Across Ontario. We are in London and Southwestern Ontario every week, including St. Thomas, Woodstock, Strathroy, Brantford, and Chatham, and we run scheduled trips further out to Barrie, Ottawa, Windsor, and beyond. Tell us where you are, and we will find a date.
