Smart neighbor uses room air cleaner to remove second-hand cigarette smoke

There is no risk-free level of exposure to second-hand smoke.

In 2014, the CDC added stroke as a disease linked to second-hand smoke. Other health consequences of second-hand smoke include lung cancer, coronary heart disease, middle ear disease and sudden infant death (SID) syndrome in children.

Cigarette smoke in her apartment smelled like trouble to life-long Virginia resident Christina Lee.

No members of her family smoke.

But in many apartment buildings, if one resident smokes, other residents suffer increased particle counts and the unpleasant smell of smoke in their apartments.

That’s what happened in Christina’s building.

As a medical office receptionist, Christina has a special awareness of the impact of cigarette smoke on a family’s health.

Plus, Christina says:

“I just hate the second-hand smoke!”

Room air cleaner to the rescue

About two months ago, Christina installed a Smoke Sentry, our small but small powerful room air cleaner.

The Smoke Sentry can be configured with a HEPA filter to capture particles and an activated carbon filter to capture odors from invisible chemicals.

Christina’s Smoke Sentry runs about six hours each day.

Before acquiring the Smoke Sentry, here’s how Christina described the smell of her apartment:

“It smelled hideous. It smelled like we were smoking also.”

Now Christina says the air in her place is definitely improved and she successfully avoids second-hand smoke.

When asked how she likes the Smoke Sentry, she said:

“I love it!”

Industrial strength for the home

Sentry Air's Model 200 Smoke Sentry effectively captures second hand cigarette smoke so it can't be inhaled.

Smoke Sentry can be equipped with HEPA filtration to trap particles and activated carbon filtration to trap chemical molecules. Many air contaminants have elements of both particles and chemical molecules.

Christina’s drive to create a healthy environment for her and her loved ones is admirable.

The Smoke Sentry is designed to be effective in second-hand smoke situations.

Its HEPA filters are true HEPA, not ‘HEPA-like.’

(The HEPA acronym stands for High-Efficiency Particulate Arrestor or High-Efficiency Particulate Air.)

True HEPA filters are manufactured and tested to in accordance with current HEPA filter standards — and that’s what we do.

Use time wisely – clean your air

Christina’s decision to run her Smoke Sentry for hours at a time is a good one.

As a room’s air is pulled through the air cleaner’s filters, each pass can remove a particle that may have slipped through on an earlier pass.

As shown in the following graphic, one test we carried out showed an 80% reduction in particles after the Smoke Sentry ran for 90 minutes.

Graphic from product test document shows reduction of particles by Smoke Sentry in 90 minutes.

Smoke is visible because it contains particles that are not fully combusted. We tested two of our portable room air cleaners — we call them PRACs – to determine how quickly each model can reduce the numbers of particles in a room. The report is on our website’s Test Data tab.

Hazardous particles

Inhaling very small particles is not good for your body.

The smallest particles, measured on the nano scale and sometimes called ultrafine particles or UFP, can travel from the nasal passages throughout the body.

Some may travel to the brain, where they can cause inflammation.

UFP can also hurt the heart and may influence how cells read genes.
