No. HEPA filters trap particles, but odors are gas-phase molecules that pass right through them. You need an oxidizing technology — hydroxyl, ozone, or thermal fogging — to actually break the odor molecule apart.

Ozone is highly effective but unsafe to breathe in treatment concentrations, so ozone is used in vacant spaces. We seal off the area, run treatment, then ventilate before the home is reoccupied. For occupied spaces, we use hydroxyl generators which are safe to breathe.

Most residential odor jobs are completed in 24–72 hours of treatment after source removal. Severe smoke or biohazard jobs requiring full structural cleaning can take 1–2 weeks.

When the odor is part of a covered loss (fire, smoke, sewage backup, biohazard), yes — almost always. We document and bill your carrier directly. Voluntary deodorization is typically not covered.

Yes — heavy nicotine smoke removal usually requires source-cleaning all surfaces, sealing primer on walls and ceilings, HVAC duct cleaning, and then hydroxyl or ozone treatment. It’s a multi-day project but the smell is fully eliminated.

Long-term pet urine often penetrates into sub-flooring and even joists. We use UV inspection to identify all affected areas, treat or remove the contaminated material, then deodorize the structure.
