Smoke can be a nuisance, whether it's from cigarettes, wildfires, or other sources. To get rid of smoke particles and odors, you need a serious filter. The best filters have a MERV rating of 13 or higher. The gold standard for smoke removal is the combination of activated carbon filters and HEPA filters.
The most effective air purifiers for cigarette smoke use a powerful fan to push air through HEPA filters. HEPA filters are mechanical filters made of polyolefin polymers and glass. They stop solid particles by mechanical action and carbon filters stop the smell of gaseous smoke by gas adsorption. For complete smoke removal, a combination of advanced H13 HEPA filters and activated carbon filters is needed.
The Medify M-112 is as close as possible to an industrial air purifier for smoke, with a CADR rating of 500 fumes and 2,500 square foot coverage. Standard HEPA filters (H10-H1) remove 99.7% of smoke particles that are 0.3 microns in size. Medify-112 uses advanced HEPA H13 filters capable of removing 99.9% of even the smallest 0.1 micron smoke particles. This means that the removal of smoke and air particles is thorough and even the smallest smoke particles are trapped in your filter. If you're looking for an air purifier to eliminate the smell of smoke without an activated carbon filter, you won't find one.
The smell of smoke is a VOC (volatile organic compounds); it is in gaseous form and cannot be stopped by mechanical filters such as HEPA filters. Carbon filters absorb the smell of smoke. For a 400 square foot studio, you can opt for the smaller Medify MA-40 instead; it has 840 square foot coverage at 2 ACH, but you would prefer 4 ACH for smoke removal. With 4 ACHs, coverage is 420 square feet, very close to 400 square feet of a studio. When shopping for an oven filter, choose one with a MERV rating of 13 or higher and look for a filter with activated carbon (also called activated carbon). The Honeywell Home Elite Allergen pleated air filter has an FPR 10 and MERV 13 rating, indicating that it is useful for filtering large and small particles. The Filtrete Healthy Living Ultimate Allergen filter has a MERV rating of 13, placing it in a class of filters designed to capture particles as small as 0.30 to 1 micron in size.
It has a first-line filtration system, including Blueair's patented HepaSilent filters with DualProtection technology and a coarse-grained activated carbon filter (smoke odor removal).To make sure your central air system is working properly, make sure you have a fresh air filter with a high MERV rating, as well as activated carbon.
