For smoke removal, HEPA filters are recommended as the gold standard for trapping fine particles, filtering out 99.97% of particles 0.3 microns in size.
That said, a HEPA filter will do a very good job of eliminating the cigarette-smoke particles it encounters. That's because the majority of these particles fall in the 0.1 to 0.5 micron range, which HEPA filters are exceptionally good at capturing.
HEPA filters not only remove the pungent odor of smoke, but filter the air significantly to rid it almost entirely of tobacco and other harmful substances to create air that is fresh, high quality, and safer to breathe.
HEPA filters are famous for being able to catch particles as small as 0.3 microns. They protect against these large smoke particles, making sure they are successfully trapped and don't get back into the indoor environment.
Upgrading to a filter rated MERV 13 or higher can be especially important during smoky periods to effectively remove fine particle pollution from smoke in the indoor air. Most furnaces and HVAC systems can accommodate a MERV 13 filter without creating equipment problems, provided that the filter is replaced frequently.
A MERV 11 filter is the most popular choice for residential homes. This type of filter can remove most of harmful contaminants from a home environment, including smoke, dust mites, pet dander, mold, pollen, dust and smog.
One easy and affordable way to make your own air cleaner at home is with a box fan and a furnace filter. These “filter fans” can filter out the small particles that are common in wildfire or wood smoke.
Smoking without a filter can give you an unpleasant feeling in your mouth and especially the tongue, this is caused by harsh smoke and excess oils making it into your mouth. Using a filter will help avoid the unpleasantness as it can absorb the oils and cool the smoke.
The EPA recommends filters with a rating of at least MERV 13, or, “as high a rating as your system fan and filter slot can accommodate.”
Besides using white vinegar to scrub the walls and floor, you can also look to your drinks cabinet for a solution. Vodka is a disinfectant and deodoriser. Spray it onto the walls, leave it for a little while and then wipe it off. Or you can simply soak a rag and wipe the walls to get rid of the smoky stench.
Levoit Core 300S Air Purifier
There are lots of options available on the market that can handle a few hundred square feet, but the Levoit Core 300s is the best air purifier for smoke in small spaces because it goes above and beyond some of the more affordable picks.
An air purifier with a carbon filter will help remove the gases present in cigarette smoke. And since smells are gases, it will also help remove the cigarette smell from your air.
HEPA filters will not remove most viruses, because they are simply too small. HEPA filters will also not remove VOCs, or volatile organic compounds, as they are also too small. Still, HEPA filter technology can be combined with other technologies that will remove these things from your air too.
Carbon filters can reduce fumes and odors, such as diesel, tobacco and wildfire smoke, pet odors, odors from cooking activities, auto exhaust, off-gassing, and more. This can be all the more important in a commercial setting, where fumes can be detrimental to occupant health.
For smoke removal, HEPA filters are recommended as the gold standard for trapping fine particles, filtering out 99.97% of particles 0.3 microns in size.
The short answer is generally yes, it is safe to run your air conditioner during a wildfire. Even more so, your AC unit may help filter wildfire smoke out of your home. While the primary function of your HVAC system is to heat and cool your home, the system also helps purify the air in your home.
Many people mistakenly believe smoking filtered cigarettes are safer than smoking non-filtered cigarettes. Filtered cigarettes are no safer than non-filtered. Filters do not protect you from bad chemicals and, in some ways, they may be more dangerous than non-filtered cigarettes.
One of the most effective ways to clean smoke from indoor environments is to attach a MERV 13 furnace filter to a box fan. The Puget Sound Clean Air Agency tested this method with air monitors and found that a box fan filter reduced airborne particulate matter dramatically.
Any materials you think will make a great filter (cotton balls, sand or gravel, uncooked pasta noodles, coffee filters, etc.) *Don't worry if you don't have all of the materials. Get creative and substitute materials with what you have! It's all part of the design process.
Activated carbon is a highly porous material that has a large surface area that can trap smoke and other odors with high efficacy. The carbon filter in the IQAir HealthPro Series contains small pellets of activated carbon that absorb the smoke odor and other harmful VOCs present in the air.
The simplest thing you can do to purify air from smoke in your home is just opening windows. Letting in a cool breeze will help whisk away some of the smell and bring badly needed fresh air into the home. This can provide some immediate relief for rooms with a stronger presence of smoke in the air.
