Air Purifier For Smoke

Poor air quality is a health hazard for children and the elderly. Maintaining purified air in your home involves more than cleaning and keeping your windows open. If you don’t have an air purifier for secondhand smoke, then consider one for your home. A range of options is available and at affordable prices.

Choosing The Best Purifiers For Smoke

If you’re not sure what to look for in a smoke purifier, we’re here to help. There are a few vital components an air purifier should have, and here we’ll show what they are.

HEPA Filter

After you find an air purifier you want, before you buy it, make sure it’s equipped with a true HEPA filter. HEPA stands for High-Efficiency Particulate Air. The filters have a fine glass mesh that removes 99.97 percent of particles from the air, reducing them to 0.3 microns in diameter.

Carbon Filter

For additional protection, an activated carbon filter is a good idea. While a HEPA filter won’t eliminate odors, some purifiers with activated carbon filters in conjunction with a HEPA filter will reduce some odors. 

Energy Star Certification

The best air purifiers are Energy Star rated. This rating ensures that the filter can trap particles, and remove allergens, and other types of harmful toxins.

AHAM Certification

The Association of Home Appliance Manufacturers (AHAM), has a voluntary certification program that gives you a clean air delivery rate (CADR) of a purifier. It also provides guidelines on the room sizes it can handle. There are CADR figures for air pollutants, including secondhand smoke. If you’re concerned about smoke,  you might want to look at air purifiers with a higher CADR.

Why Is Cigarette Smoke Harmful?

The dangers of secondhand smoke are known, but there’s another threat you may not be familiar with – thirdhand smoke. This type of smoke refers to the lingering smell attached to the skin, clothes, and other items things after it’s exposed to cigarette smoke, according to Healthline.

Even though the smoke isn’t in the air, the smoke residue contains hazardous chemicals that can be released after touching and moving the affected areas. Cigarette smoke contains almost 4,000 chemical compounds, says Allergy and Air. The EPA even classifies cigarette smoke as a Group A carcinogen that contains very small particles that can penetrate the lungs.

A host of health problems are caused by exposure to cigarette smoke beyond just cancer. Many kinds of breathing and lung diseases are caused by smoke exposure  — even secondhand — such as emphysema, COPD, and asthma. Children are vulnerable to smoke, and so are infants, as it causes Sudden Infant Death Syndrome (SIDS).

According to WebMD, bad indoor air quality  can cause coughing, chest tightness, sore throat, watery or itchy eyes, shortness of breath, and even asthma

Why Buy An Air Purifier?

As already noted, opening the windows isn’t enough to clear your home of smoke. If you live with a smoker or are exposed to second-hand smoke, an air purifier is the best way to mitigate the harmful effects.

The Mayo Clinic explains that tobacco smoke contains harmful gases and well as particles. While HEPA filters clean particles from the air, they don’t eliminate gases or particles that have settled on walls, upholstery, and other surfaces. Purifiers that generate ozone, which is bad for your lungs, are not effective against air contaminants.

Air purifiers with HEPA filters might not be able to remove all of the toxins and smoke smell from your home. Studies by the US National Institutes of Health have shown that air purifiers can indeed reduce the harmful particles in the air, it does not eliminate exposure to nicotine in a home where smoking occurs.
