How to Stop Cigarette Smoke from Coming Through Vents

How to Stop Cigarette Smoke from Coming Through Vents

Air ducts and vents can distribute secondhand smoke throughout a home and from one apartment to another in a building. Cigarette smoke is associated with many health problems, including lung cancer. It may produce an odor and leave behind yellow stains on walls and brownish residue on curtains and drapes. No matter how much deodorizer your spray or vacuuming and cleaning you do, it won’t reach everywhere. Continue reading to learn how to stop cigarette smoke from coming through vents in the first place.

Clean the Vents

To start, it helps to clean the nicotine residue off vents. You’ll need to remove each vent from its fitting and place it in a well-ventilated area. Choose your cleaning solution; mild dish soap will often do (if using a chemical cleaner, wear gloves and safety goggles). Avoid abrasive tools; instead, use a soft cloth or sponge to wipe down the vent. You can clean the slats with a narrow soft brush.

Install a Charcoal Register Vent Filter

Filters with activated charcoal are designed to fit inside vents. Depending on the product, it can trap dirt, dust, and pollen as well as prevent objects from falling into air ducts. One type of vent filter uses a self-charging electrostatic material to attract pollutants. Smoke and other particles become trapped and only filtered, smoke-free air enters your home. 

Seal Vent Gaps with Insulation Padding and Painter’s Tape

Cigarette smoke can also drift in through gaps around air vents, air conditioners, and heaters. This smoke often bypasses any filters. To use insulation padding, tuck it into any gaps and lay it over the surrounding surface; then secure it with painter’s tape. Placing padding and tape isn’t an infrastructure change so won’t violate your lease agreement. But first, talk to your landlord to see if they have a better way to seal gaps.

Have Your Air Ducts Cleaned Professionally

Cigarette smoke is most likely not limited to the vent surface. The chemicals in cigarette smoke can reach remote areas of air ducts. Air duct cleaning helps whether you have a persistent smoke problem, are a smoker, or moving into a home where there were smokers. An HVAC professional is equipped with equipment and cleaning products that can reach where other solutions can’t and effectively break down smoke molecules.

How to Eliminate Cigarette Smoke Odors

Various types of cleaners can work. But you don’t have to use a chemical cleaner. You can wipe the vent down with plain vinegar or a mix of 1 tablespoon of ammonia in 1 cup of water. If this doesn’t work, mix 1 part bleach into 4 parts warm water and soak the vent for a few hours before rinsing it. Let the vent cover dry and reinstall it.

Blocking Smoke from Other Sources

Knowing how to stop cigarette smoke from coming through vents won’t always eliminate a smoke problem. Consider other sources as well, and take action to prevent smoke from continuing to get in. Here are some solutions:

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.

My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
