Indoor air pollution is just a serious problem. In line with the Environmental Protection Agency (EPA), air pollution levels are two to five times higher indoors. In a few buildings with a lack of proper ventilation, the indoor air may be 100 times more polluted compared to the air outside! This is because modern buildings are constructed with energy efficiency in mind. However, the tight seals that make a home energy-efficient also trap pollutants inside. On top of that, the average American takes nine out of ten breaths indoors, so it’s imperative to ensure that your indoor air is free from allergens and other impurities.

16 Best Air Purifiers 2022 | The Strategist

Air purifiers eliminate allergens, toxic chemicals, and other dangerous pollutants. This 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 purifier for your needs.

Common Indoor Air Pollutants

What’s the origin of indoor air pollution? When it comes to organic pollutants, mold and dust mites are everywhere – and they’re the two most typical reasons for year-round allergic rhinitis (hay fever). Pollen can be a pervasive allergen that always finds its way into your home since it is so small and sticky. When you yourself have pets, they’ll surely spread their dander to every nook and cranny of your home. Many viruses and bacteria will also be airborne.

Even though they’re not organic allergens, Volatile Organic Compounds (VOCs) cause many individuals 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 present in your indoor air, along with toxic heavy metals like airborne lead, mercury vapor, and radon.

How Air Purifiers Work

HEPA air purifiers use a HEPA air filter, that has been developed by the Atomic Energy Commission in the 1940s as a way to filter radioactive contaminants. HEPA filters set the standard for air purifiers: to be classified as HEPA, a filter must capture a minimum of 99.97% of pollutants at 0.3 microns or larger. Top-selling HEPA air purifiers range from the Austin Air purifier, 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 now been treated by having an additional chemical, normally either potassium iodide or potassium permanganate; these chemicals, known as chemisorbents, increase the carbon filter’s power 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 be worried about changing HEPA filters, however, if the collection plates aren’t cleaned frequently, they quickly lose efficiency. Also, beware that some electrostatic filters emit ozone, that will be known to be a robust lung irritant and can be very irritating with a individuals with asthma or allergies. The Friedrich air purifier is, undoubtedly, the very best electrostatic air purifier, along with the general top-ranked air purifier in previous Consumer Reports rankings.

Charged media filters give pollutants an electrostatic charge before collecting them in a conventional filter. Charged media filters are normally quite effective, 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 main advantage of charged media filters is that they are quieter and more energy-efficient than HEPA air purifiers. The Blueair air purifier is the best charged media filter, and it doesn’t emit ozone.

Where and How exactly to Use an Air Purifier

If you suffer with allergies (especially if you’re allergic to dust mite allergen), then the very best place for an air cleanser can be your bedroom. It’s essential to possess clean air in your bedroom because you spend about a next of your daily life there. 防虹吸隔氣 If you’re allergic to animal dander and have pets, then you may want to position an air cleanser in the area where your pets spend most of these time-and keep carefully the pets from your bedroom! Also, you should not place an air cleanser in the corner of a space; it must be at the very least several feet away from the walls for maximum air flow.

You need to run your air purifier continuously for optimum performance. Most air purifiers have high and low settings. Even if you go on a break, we recommend that you keep your air purifier running on low. Otherwise, you’ll go back to a residence high in polluted air! If you should be worried about your electric bill, find out how much energy an air cleanser 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, many of the pollutants are released back to the air, quite often ultimately causing dirty spots on nearby walls. Besides the truth that they don’t perform a good job of cleaning the air, ozone generators and ionizing cleaners also emit ozone. Ozone, a principal part of smog, may potentially result in a critical 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 who 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 newest Ionic Breeze Quadra, inspite of the addition of OzoneGuard, a computer device meant to remove a few of the dangerous ozone emitted by the Ionic Breeze.

Consumer Reports highlights: “Our air-cleaning tests reveal 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.”

How exactly to Choose the Best Air Purifier

The air purifier market is vast and riddled with confusing and often misleading advertising schemes. If you’re searching for an air cleanser, then you should first consider what sort of pollutants you’re wanting to eliminate. As an example, in the event that you end up having cigarette smoke, then you’ll desire to ensure that your air purifier has the capability to eliminate fumes, VOCs, and other gases.
