1. Why Use an Air Purifier?
Are air purifiers really necessary? We sure think so. Using an “air cleaner” has long been best practice in medical facilities and other places where health is a key concern. Some of the earliest technology has evolved and is still being used, such as true HEPA filter and other HEPA filtration systems. Portable air purifiers bring with them a ton of potential benefits and uses. Let’s explore a few:
Remove Airborne Pathogens
The common cold, the flu and even COVID-19 can all become airborne. If a sick person enters your home and coughs, sneezes or simply breathes, they may release a viral or bacterial pathogen into your indoor air. Aerosolized pathogens can remain airborne for hours in poorly ventilated areas. That means they’re just hanging out in the air, waiting for you or your family to breathe them in and become infected.
Enter air purifiers. Many of these devices are highly rated for their ability to remove airborne pathogens. And while an air purification system shouldn’t be the only measure you take to protect your family from COVID-19 and similar health threats, it can certainly help, according to the Environmental Protection Agency (EPA).
Pet dander, dust, pollen, mold, mildew, fungus, smoke are all a type of allergen. The list of indoor allergens is a long one. And if you suffer from allergies, you don’t have to be told how quickly allergies can ruin your day.
Will an air purifier help with allergies? Absolutely – one comprehensive study that reviewed 15 past studies on air purifiers and allergies found that portable air purifiers provide broad benefits to those with asthma, allergic rhinitis and similar conditions. Filtering the air flow in your home alleviates airborne pollutants, dust mites , smoke particles, gaseous pollutants, pet odor and much more.
HEPA air purifiers are typically the best air purifiers for allergies, but some devices are rated better for reducing certain types of allergens. We discuss the best air purifiers for allergies in more detail below.
Volatile organic compounds (VOCs) are chemicals found in many home products, such as paint, carpet, oil, varnishes, adhesives, cleaning products, air fresheners and more. These chemicals enter indoor air through a process called off-gassing, meaning they are released over time as a gas. Scientists have identified more than 1,200 types of VOCs, but some of the most common in our daily lives are 1,3-butadiene, xylene, toluene, tetrachloroethylene, methylene chloride, formaldehyde, ethylene glycol and benzene.
Because there are so many VOCs that can come from so many different sources, the effects of exposure to VOCs can vary widely. In the short term, VOC exposure has been tied to worsening asthma symptoms, nausea, vomiting, dizziness, headaches and irritation of the throat, nose and eyes. Over the long term, VOC exposure has been linked to nervous system damage, harm to the kidneys, liver damage and cancer.
There is no safe level of exposure to VOCs. However, young children, the elderly and those with respiratory problems face the greatest risks from exposure. The good news is that the best air purifiers are specifically designed to remove gases like VOCs from indoor air. An activated carbon filter is considered the gold standard for reducing VOCs with an air purifier.
Think back to a time when you couldn’t breathe well. Maybe you had a lung infection or a similar respiratory health issue. Getting through the day was hard enough, but when it came time to go to sleep, you probably had some trouble. Sleep and the ability to breathe easily are inextricably linked to each other.
Generally, that’s how air purifiers improve sleep. By taking irritants and allergens out of the air, these devices keep you breathing easy and sleeping deeply. Also, the low, soothing sound of an air purifier running at night can serve as white noise, which has been shown to promote better sleep.
Promote Long-Term Health Through Clean Air
We have already discussed some of the short-term health benefits of air purifiers, but these devices can also promote long-term health. For example, keeping your indoor air clean means reducing exposure to radon and asbestos, both of which have been linked to lung cancer after long-term exposure.
Unfortunately, people are exposed to countless potentially harmful substances in the air they breathe every day. Air quality researchers have identified thousands of these potential threats, but much remains to be learned – we could be exposed to harmful substances for years without ever realizing they were in the air and they were harmful. A top-rated air purifier provides a sort of security blanket to keep all of those potential threats under wraps. Talk about peace of mind.
