Need to Know Before You Buy An Air Purifier

Clean air is essential for our lungs, blood circulation, heart, and other physiological systems, regardless of the season. However, your home's air is likely dirtier than you realize. The concentration of certain contaminants is often two to five times higher indoors than outdoors, according to the Environmental Protection Agency. Blueair, Dyson, GermGuardian, Holmes, Honeywell, Hunter, Idylis, and Kenmore are some of the most popular air purifier brands in the world.

Pollutants like smoke from tobacco, burning wood, and cooking, gases from cleaning products, dust mites, mold, and pet dander all contribute to an unhealthy indoor environment that can harm the body.

Fine particles of a diameter of 10 micrometers or less, such as those found in dust and smoke, are extremely dangerous because they can penetrate deep into the lungs. Breathing them in for just a few hours or days might irritate the lungs and trigger asthma attacks. It's also been connected to heart attacks in persons who already have a cardiac condition. Long-term exposure to high particle levels has been linked to bronchitis, reduced lung function, and early death in studies.

Adhesives, paints, and cleaning products produce volatile organic compounds (VOCs), including formaldehyde, into the air. VOCs can irritate the nose, throat, and eyes, as well as induce headaches, nausea, and damage to the liver, kidneys, and neurological system. Some gases, such as radon, have been linked to lung cancer and death in humans. Removing polluting sources and ventilating with fresh, clean outdoor air are the greatest approaches to enhancing indoor air quality. When those approaches are inadequate or impossible, room air purifiers can help.

Types of Air Purifiers

Air purifiers use a variety of technologies to reduce indoor pollution. Some are more effective than others. Therefore, it is important to keep this in mind before making the purchase decision.

1) Models with mechanical filters: Fans drive air through a thick web of fine fibers in residential air purifiers using pleated filters, trapping pollutants. HEPA filters—those authorized to collect 99.97 percent of particles of a specified size (0.3 micrometers in diameter—for example, smoke and paint pigments)—have a very thin mesh. Larger particles, such as pollen, dust, and some mold spores, can also be removed by HEPA filters while they're suspended in the air. Mechanical filters have limitations when it comes to gases and odors. They can also be costly to maintain. Mechanical filters must be replaced every six to twelve months and can cost up to $200 per filter, with the average cost being around $80.

2) Models with activated carbon filters: Sorbent filters, rather than catching particles like mechanical filters, use activated carbon to capture some odor-causing chemicals in the air. They may be able to combat some gases, but formaldehyde, ammonia, and nitrogen oxide are not among them. Many air purifiers will feature both an activated carbon filter and a pleated filter for capturing particles because activated carbon filters do not combat particles. However, activated carbon filters become saturated more quickly than pleated filters and must be replaced more frequently—every three months as opposed to every six to twelve months for pleated filters. Make careful to account for replacements in your budget: Filters made of activated carbon can cost up to $50 apiece.

3) Electronic air purifiers: Electrostatic precipitators and ionizers charge particles in the air, causing them to attract magnetically to plates on the machine or neighboring surfaces. However, these residential air purifiers produce ozone, which is proven to be harmful to the health of human beings.

4) Ultraviolet germicidal irradiation (UVGI): UV lamps, according to certain manufacturers, kill bacteria, airborne viruses, and fungal spores. However, some bacteria and mold spores are UV-resistant. To be effective, the UV light must be strong enough and the exposure time must be long enough (minutes to hours rather than the few seconds characteristic of most UVGI air purifiers).

5) Photocatalytic oxidation: PCO produces hydroxyl radicals that oxidize gaseous contaminants using UV light and a photocatalyst, such as titanium dioxide. This process can produce toxic by-products such as ozone, nitrogen dioxide, formaldehyde, and carbon monoxide, depending on the pollutant.

3 Best Residential Air Purifiers

1) Alen BreatheSmart 75i Pure: While operating at its lowest and highest settings, the 75i proved to be excellent at catching and eliminating dust and smoke. It has a floor area of up to 1,300 square feet, which is much larger than the others featured here.

2) Samsung Cube Stack: At both high and moderate speeds, the Samsung Cube Stack achieves Excellent particle removal results. It does, however, come at a cost. Two Samsung Cube units are stacked on top of each other to create a far more powerful cleaning machine. You'll need two units to achieve the required effect, making it the most expensive air purifier in the rankings. It's also not as silent as the top-rated model.

3) Blueair Classic 605: At slower speeds, the Blueair Classic 605 is quiet, but at high speeds, it is boisterous. It will quickly clean the air, but you won't want to stay in the room while it is doing so. The machine is heavy at 30 pounds, but it features casters that make it easy to move about. It claims to have a 775-square-foot capacity.
