Eliminate Smoke, Pet & Mold Odours That Air Fresheners Can't Touch
Professional ozone shock treatment neutralizes odour-causing molecules at the molecular level — smoke damage, pet urine, mold, flood aftermath. Not a cover-up. An elimination. Space must be vacant during treatment.
Common Household Odours
Most home odours are pleasant — the baking of pies or cakes, the burning of candles, a pot roast in the oven. However, sometimes we get odours in our homes that are offensive to our sense of smell and, try as we might, we can't get rid of them. Here are common, tough-to-get-rid-of household odours we're asked about in Calgary homes.
Rotting Trash
Trash left too long in a warm kitchen or garage can leave behind an odour that lingers well after the source is removed.
Mold & Mildew
Musty, damp smells from mold and mildew can settle into carpets, drywall, and HVAC systems and keep coming back.
Regardless of where the odour begins, it always seems to permeate the entire house — which is why it's essential to find out if ozone odour removal can get rid of the odour at the root level and leave you with a clean, fresh-smelling home again.
Ozone Destroys Odour — It Doesn't Mask It
Ozone (O₃) is a highly reactive form of oxygen. When introduced to a sealed space, ozone molecules react with and break down the volatile organic compounds responsible for odour — smoke residue, pet urine metabolites, mold volatile compounds, flood bacteria — converting them into inert byproducts.
This is fundamentally different from air fresheners, sprays, or candles, which add competing scents to mask the source. Ozone eliminates the source. After treatment, the ozone dissipates over several hours and leaves no chemical residue.
Ozone is a gas that's both naturally occurring and man-made. This gas has oxidizing properties, which allow it to tackle foul odours at the molecular level. When an ozone air purifier treats your house, the ozone destroys the source of the odour by breaking apart its molecules so the smell goes away — much more effective than sprays or air fresheners, which only "perfume" the air and don't get rid of the source of the stench.
Important: The space must be completely vacant during ozone treatment — people, pets, plants, and sensitive electronics should be removed. We advise on the appropriate ventilation period before re-entry based on the treatment concentration and room volume.
Not Sure If Ozone Is Right for Your Odour?
Tell us what's happening — smoke, pet, mold, or flood odour — and we'll advise on the right treatment plan for your Calgary home before you book anything.
Is an Ozone Odour Eliminator Right For Me?
Ozone eliminators have been proven effective at getting rid of even the most stubborn and foul odours. However, this powerful technology is best used by a professional ozone odour removal specialist because of the toxic nature of ozone in high quantities. If you have stubborn pet odours or cigarette smoke odours you can't get rid of, an ozone deodorizing treatment could be just the trick.
Odour Sources That Respond to Ozone
Fire & Smoke Damage
Smoke odour embeds in walls, insulation, upholstery, and HVAC systems. Ozone treatment combined with duct cleaning effectively eliminates smoke contamination after a fire or heavy smoking damage.
Pet Urine & Dander
Pet urine metabolites are stubborn and resistant to surface cleaning alone. Ozone shock treatment reaches into subfloor, wall cavities, and HVAC where the odour persists long after the source is removed.
Mold & Flood Aftermath
Mold volatile organic compounds produce the characteristic musty odour that remains even after remediation. Ozone treatment neutralizes these compounds after mold remediation to confirm the space is truly odour-free.
Combine with Duct Cleaning for Complete Elimination
Odours that reached your ductwork need two treatments: ozone for the space, duct cleaning with Benefect disinfection for the delivery system. We can schedule both in one appointment.
Ozone Treatment Questions
How long do we need to vacate for ozone treatment?
Treatment duration depends on the odour severity and room volume — typically 2–6 hours for the active treatment phase, followed by 2–4 hours of ventilation before re-entry. We provide a specific timeline at booking based on your situation. Most treatments can be completed in a single day while occupants are away from the home.
Is ozone treatment safe?
Professional ozone shock treatment is safe when the space is properly vacated and the ventilation period is observed before re-entry. Ozone at treatment concentrations is hazardous to breathe — which is why vacancy during treatment is non-negotiable. After the treatment and ventilation window, ozone dissipates completely and leaves no residue. It is used routinely in fire restoration, flood remediation, and vehicle detailing.
Will one treatment be enough?
For most odour sources, a single professional ozone shock treatment is sufficient. Severe smoke damage or long-standing pet odour contamination may require two treatments, especially if the source material (carpet, drywall, subfloor) has not been physically removed or cleaned first. We advise on the likely treatment count at the assessment.
