Up in Smoke: A Guide to the Best Way to Get Rid of Smoke Smell in Apartment Units

The Best Way to Get Rid of Smoke Smell in Apartment Units (Quick Answer)

The best way to get rid of smoke smell in apartment spaces is to combine thorough surface cleaning, ventilation, and odor-absorbing materials — and in severe cases, professional restoration.

Here’s a quick overview of the most effective steps:

1. Ventilate immediately — Open windows on opposite sides for cross-ventilation and run exhaust fans
2. Clean all hard surfaces — Wash walls, ceilings, and floors with a TSP or vinegar-based solution, top to bottom
3. Treat fabrics and carpets — Apply baking soda, let it sit, then vacuum; wash or replace curtains and soft furnishings
4. Replace HVAC filters — Change filters and clean vents to stop odor from recirculating through the air system
5. Use odor absorbers — Place activated charcoal, vinegar, or coffee grounds around the space
6. Prime and repaint — Use an odor-sealing shellac-based primer before repainting walls and ceilings
7. Replace what can’t be saved — Carpet padding, fabric blinds, and heavily saturated upholstery often need to go
8. Call a professional — For heavy or long-term smoke damage, certified restoration experts get results that DIY can’t

You walked into the apartment and it hit you immediately — that stale, sharp smell of old cigarette smoke baked into every surface. Maybe you’re a landlord prepping a unit for new tenants. Maybe you just moved in and the previous resident smoked for years. Either way, you know it’s not just unpleasant. It’s stubborn.

Smoke odor doesn’t just float in the air. It embeds itself into walls, ceilings, carpets, furniture, and even the HVAC system. According to research on long-term smoke exposure in homes, some people report the smell persisting for over a decade — even after painting and basic cleaning. And beyond the discomfort, thirdhand smoke residue left on surfaces poses real health risks, including triggering asthma and allergic reactions. On top of that, smoking in a home can reduce property resale value by nearly 30%.

The good news? With the right approach, it can be fixed.

I’m Cole Nudel, a disaster restoration professional with A1 Water Damage Restorations in the Denver area, and helping property owners tackle stubborn damage — including the best way to get rid of smoke smell in apartment units — is exactly what I do. In this guide, I’ll walk you through every step, from quick DIY fixes to knowing when it’s time to call in the pros.

Understanding Why Smoke Odors Linger in Apartments

If you’ve ever wondered why that “old bar” smell won’t leave your living room, the answer lies in something called thirdhand smoke. Unlike smoke (what the smoker inhales) or secondhand smoke (what others nearby breathe), thirdhand smoke is the invisible, toxic residue that stays behind.

Cigarette smoke contains thousands of chemicals, including nicotine and tar. When someone lights up, these particles don’t just vanish; they drift and settle on every available surface. Because apartments are often smaller, enclosed spaces, these particles concentrate quickly. They are incredibly tiny—often 0.3 microns or smaller—allowing them to penetrate deep into porous surfaces like drywall, wood, and upholstery.

Over time, this residue creates a sticky film that “off-gasses” Volatile Organic Compounds (VOCs) back into the air for weeks, months, or even years. This is why a simple spray of air freshener never works; it’s just putting a tiny band-aid on a structural problem. For a deeper look at how smoke interacts with building materials, you can check out more info about fire damage services.

According to How to Get Rid of Smoke & Other Odors from Your Apartment, smoke can even travel through pipe shafts and central ventilation systems, meaning a smoker in unit 2B could be the reason unit 3B smells like a chimney.

The Science Behind the Best Way to Get Rid of Smoke Smell in Apartment Walls

When smoke hits a wall, it doesn’t just sit on the paint; it etches into it. You’ll often notice a tell-tale yellow-brown film on white walls or around door frames. This is a mixture of nicotine and tar that has hardened over time.

This residue is slightly acidic, which means it can actually damage the finish of your cabinets or the texture of your ceiling. If you try to paint directly over this film without cleaning it first, the moisture in the new paint will reactivate the odor molecules. Within a few weeks, the smell will “bleed” through the new coat of paint, and you’ll be right back where you started. This is why professional-grade cleaning is the essential first step in the best way to get rid of smoke smell in apartment renovations.

Immediate Steps and the Best Way to Get Rid of Smoke Smell in Apartment Air

Before you start scrubbing, you need to clear the air—literally. The goal is to move as much contaminated air out of the apartment as possible while preventing the smell from settling further into the furniture.

Ventilation and Airflow

The first thing we recommend at A1 Water Damage Restorations is creating positive pressure. If you just open one window, the air just swirls around. Instead, open windows on opposite sides of the apartment to create a cross-breeze. Place a box fan in one window facing outward to pull the smoky air out, while another fan pulls fresh air in from the other side.

High-Efficiency Filtration

While you work, run a True HEPA air purifier. According to industry standards, True HEPA filters capture 99.97 percent of smoke particles as small as 0.3 microns. To be effective, the purifier should have an activated carbon filter. While the HEPA filter grabs the physical particles, the carbon filter absorbs the gaseous VOCs that cause the actual scent. For those looking for a “quick fix” for minor incidents like burnt toast, How to Get Rid of Smoke Smell in Your House, Fast suggests running these units on high for at least an hour to see immediate results.

Neutralizing Odors with Household Items

While you’re ventilating, you can use common household items to start absorbing the airborne odors. These aren’t permanent solutions for heavy smokers, but they help significantly during the cleaning process.

• Distilled White Vinegar: The acetic acid in vinegar bonds with volatile odor compounds. Place several bowls of vinegar around the apartment for 24 hours.
• Activated Charcoal: This is more porous than regular charcoal and is a powerhouse at “trapping” odors.
• Baking Soda: An alkaline substance that reacts with acidic smoke molecules to neutralize them.
• Coffee Grounds: Believe it or not, the nitrogen in coffee grounds helps neutralize sulfur-like smells in the air.

Deep Cleaning Surfaces: From Ceilings to Parquet Floors

Once the air is moving, it’s time for the “elbow grease” phase. We always tell our clients in the Denver Metro Area: Clean from the top down. If you clean the floors first, you’ll just drip dirty, nicotine-filled water onto them when you move to the ceiling.

The Walls and Ceilings

The ceiling is often the most neglected part of an apartment, but since smoke rises, it’s usually the most contaminated. For heavy residue, we recommend using Trisodium Phosphate (TSP) mixed with hot water. TSP is a heavy-duty cleaner that cuts through the sticky tar film that soap and water can’t touch.

Wipe the walls using microfiber cloths, changing your water bucket frequently. If the water turns yellow or brown, you’re doing it right! If you are dealing with significant soot from a kitchen fire, our Denver Fire Damage Restoration team uses specialized dry-cleaning sponges to lift soot before applying liquids, which prevents smearing.

Hardwood and Parquet Floors

Parquet floors are beautiful but porous. If smoke has settled into the wood, a simple mop won’t cut it. Use a wood-safe cleaner mixed with a bit of white vinegar. For deep-set smells, the floor might need to be lightly sanded and refinished to remove the top layer of contaminated wood.

Addressing HVAC Systems and Hidden Residue

Your HVAC system is the lungs of your apartment. If you don’t clean it, you’re just recirculating smoke every time the AC kicks on.

1. Change the Filter: This is non-negotiable. Use a high-quality pleated filter.
2. Clean the Vents: Take off the vent covers and wash them in the sink. Use a shop vac with a HEPA filter to reach as far into the ducts as possible.
3. The “Hidden” Spots: Don’t forget light bulbs! When light bulbs get hot, they “cook” the nicotine residue on their surface, releasing the smell. Wipe down switch plates and the tops of door frames too.

If you’re in the Boulder area and the smell persists after these steps, our Boulder Fire Damage Restoration Experts can perform a professional duct cleaning to reach deep into the building’s infrastructure.

Advanced Restoration: Priming, Painting, and Professional Tools

Sometimes, no matter how much you scrub, the smell lingers. This is because the smoke has migrated through the paint and into the drywall itself.

The Power of Odor-Sealing Primers

Standard latex primer is like a screen door; it won’t stop odors. To truly lock in the smell, you need a shellac-based or high-quality oil-based primer (like Zinsser B-I-N or Kilz Restoration). These primers create an impermeable barrier that traps the smoke molecules inside the wall. Once the primer is dry, you can paint over it with any color you like. For residents in the Cherry Creek area, our Cherry Creek Fire Damage Restoration team often uses these industrial-grade sealants to ensure a “like-new” finish.

Professional Deodorization Tools

When DIY methods fail, pros use two main tools:

1. Ozone Generators: These machines create O3, which chemically breaks down odor molecules. Warning: Ozone is hazardous to humans, pets, and plants. The apartment must be completely vacant during treatment.
2. Hydroxyl Generators: These are safer than ozone and can sometimes be used while people are present, though they take longer to work.

When the Best Way to Get Rid of Smoke Smell in Apartment Units Requires Replacement

We hate to be the bearer of bad news, but some things just can’t be saved.

• Carpet Padding: The carpet itself might look clean after a steam, but the foam padding underneath acts like a giant sponge for smoke. If the smell is heavy, you usually have to replace the pad.
• Popcorn Ceilings: Because they are so porous and fragile, you can’t really “scrub” them. Often, the best move is to scrape them off and start fresh.
• Fabric Blinds and Curtains: These are often cheaper to replace than to professionally dry-clean.
• Heavily Saturated Upholstery: If a sofa has been in a smoker’s home for 10 years, the smoke is deep in the foam. Replacement is usually the only permanent fix.

Frequently Asked Questions about Smoke Removal

Is the landlord legally responsible for removing smoke smell?

In most cases, yes. Landlords are generally required to provide a “habitable” environment. If a previous tenant’s smoking has left the unit smelling so bad it causes physical distress or health issues, the landlord is typically responsible for the remediation. However, if you are the one who smoked and are moving out, the landlord may deduct the cleaning costs from your security deposit. Always check your specific lease agreement and local Denver or Colorado housing laws.

How long does it take to completely remove cigarette smoke?

A “smoke reset” is usually a 1 to 3-day job depending on severity.

• Light smell: 24–48 hours of ventilation and vinegar bowls.
• Moderate smell: 2 days of deep cleaning and carpet steaming.
• Heavy smell: 3+ days, including TSP washing, priming/painting, and ozone treatment.

Are ozone generators safe for DIY use in apartments?

We generally advise against DIY ozone use. If used incorrectly, ozone can damage natural rubber, electrical wire coatings, and fabrics. More importantly, it is a lung irritant. Professionals use specialized monitors to ensure the air is safe before anyone re-enters the space. If you do use a small consumer unit, you must vacate the premises and air the unit out for at least 2 hours afterward.

Conclusion

Getting rid of smoke smell is a marathon, not a sprint. Whether you’re tackling a minor “burnt dinner” incident or a decade’s worth of cigarette residue, the best way to get rid of smoke smell in apartment units is to be systematic. Start with the air, move to the surfaces, and don’t be afraid to seal the walls or replace the carpet if the odor refuses to budge.
