Indoor air pollution is really a serious problem. In line with the Environmental Protection Agency (EPA), air pollution levels are two to five times higher indoors. In certain buildings with deficiencies in proper ventilation, the indoor air might be 100 times more polluted compared to air outside! The reason being modern buildings are constructed with energy efficiency in mind. However, the tight seals that make a property energy-efficient also trap pollutants inside. Along with that, the average American takes nine out of ten breaths indoors, so it’s imperative to make sure that your indoor air is free from allergens and other impurities.
Air purifiers eliminate allergens, toxic chemicals, and other dangerous pollutants. This informative article explains why people use air purifiers, how they work, which air purifiers you need to avoid, and how to choose the very best air cleanser for your needs.
Common Indoor Air Pollutants
What’s the source of indoor air pollution? In terms of organic pollutants, mold and dust mites are everywhere – and they’re both most common factors behind year-round allergic rhinitis (hay fever). Pollen can be a pervasive allergen that always finds its way into your property since it’s so small and sticky. When you have pets, they’ll surely spread their dander to every nook and cranny of one’s home. Many viruses and bacteria may also be airborne.
Although they’re not organic allergens, Volatile Organic Compounds (VOCs) cause many people to see allergic reactions and other health problems. VOCs include formaldehyde, fragrances, pesticides, solvents, and cleaning agents. VOCs can enter the air through chemical off-gassing from furniture, new carpets, adhesives, plastics, and various building materials. Furthermore, many VOCs are known carcinogens (cancer-causing agents).
Environmental contaminants like cigarette smoke, carbon dioxide, carbon monoxide, and nitrogen dioxide may also be within your indoor air, as well as toxic heavy metals like airborne lead, mercury vapor, and radon.
How Air Purifiers Work
HEPA air purifiers work with a HEPA air filter, that has been produced by the Atomic Energy Commission in the 1940s as a way to filter radioactive contaminants. HEPA filters set the conventional for air purifiers: to be classified as HEPA, a filter must capture no less than 99.97% of pollutants at 0.3 microns or larger. Top-selling HEPA air purifiers are the Austin Air cleaner, available with a HEGA (High Efficiency Gas Adsoprtion) filter, along with air purifiers from IQAir, Allerair, Blueair, and Honeywell.
Activated carbon filters remove gases, odors, and chemical toxins. The carbon is “activated” if it is treated with oxygen, which opens up countless tiny pores to attract and adsorb chemicals. Impregnated carbon filters have been treated with an additional chemical, normally either potassium iodide or potassium permanganate; these chemicals, called chemisorbents, increase the carbon filter’s capability to trap VOCs and other chemically reactive gases.
Electrostatic filters use an electrostatic charge to attract pollutants and trap them on collector plates. These filters are great for those who don’t want to have to bother about changing HEPA filters, if the collection plates aren’t cleaned frequently, they quickly lose efficiency. Also, beware that some electrostatic filters emit ozone, that is considered to be a robust lung irritant and can be quite irritating with a people with asthma or allergies. The Friedrich air cleanser is, definitely, the very best electrostatic air cleanser, as well as the entire top-ranked air cleanser in previous Consumer Reports rankings.
Charged media filters give pollutants an electrostatic charge before collecting them in a normal filter. Charged media filters are typically quite effective 辦公室空氣清淨機 , but like electrostatic filters, they lose efficiency rapidly-and they could require frequent and expensive filter changes. Some charged media air filter units also emit ozone. The advantage of charged media filters is they are quieter and more energy-efficient than HEPA air purifiers. The Blueair air cleanser is the best charged media filter, and it generally does not emit ozone.
Where and Just how to Use an Air Purifier
If you have problems with allergies (especially if you’re allergic to dust mite allergen), then the very best area for an air purifier can be your bedroom. It’s essential to own climate in your bedroom because spent about a next of your daily life there. If you’re allergic to animal dander and have pets, then you might want to put an air purifier in the room where your pets spend most of these time-and keep the pets from the bedroom! Also, you shouldn’t place an air purifier in the corner of an area; it ought to be at the very least several feet from the walls for maximum air flow.
You should run your air cleanser continuously for optimum performance. Most air purifiers have high and low settings. Even if you go on vacation, we recommend that you keep your air cleanser running on low. Otherwise, you’ll come back to a residence high in polluted air! If you are worried about your electric bill, find out how much energy an air purifier uses before buying it. Typical HEPA air purifiers can use anywhere from 50 watts on low to 200 watts on high. For comparison, a normal lamp uses about 60 watts, while a normal computer uses about 365 watts.
Air Purifiers to Avoid
Avoid ozone generators and ionizing air cleaners. These air purifiers create ions that attract pollutants; however, most of the pollutants are released back to the air, sometimes leading to dirty spots on nearby walls. Besides the fact they don’t perform a good job of cleaning the air, ozone generators and ionizing cleaners also emit ozone. Ozone, a main part of smog, may potentially lead to a significant asthma attack.
Moreover, David Peden, researcher at the Center of Environmental Medicine and Lung Biology at the University of North Carolina, has examined how ozone exposure might exacerbate the allergic response of people that are allergic to dust mites, and his results claim that ozone worsens the asthmatic response. The EPA has warned consumers against using ozone generators, and Consumer Reports recommends against the most recent Ionic Breeze Quadra, despite the addition of OzoneGuard, a computer device meant to eradicate a number of the dangerous ozone emitted by the Ionic Breeze.
Consumer Reports highlights: “Our air-cleaning tests show that the Ionic Breeze with OzoneGuard does an undesirable job of removing smoke, dust and pollen particles from the air when new and after 500 hours of continuous use” and “the Ionic Breeze with OzoneGuard still adds ozone to the air.”
Just how to Buy the Best Air Purifier
The air cleanser market is vast and riddled with confusing and often misleading advertising schemes. If you’re buying an air purifier, then you should first consider what type of pollutants you’re wanting to eliminate. For instance, in the event that you experience cigarette smoke, then you’ll want to ensure your air cleanser has the capability to eliminate fumes, VOCs, and other gases.
