Although they may seem like a new innovation, air purifiers have been around for more than 200 years. What started as protective masks for fireman, air purifiers have now evolved the ability to protect you and your family from airborne pollutants. As allergies and asthma now affect more than 50 million Americans, the concern for safe indoor air quality has rapidly increased. Now more than ever, Americans are looking for ways to improve their indoor air quality. Air purifiers lead the pack in advancements for cleaner air. represents the top air purifier and air cleaner manufacturers including Austin Air, Blueair, and IQAir. Allergens like smoke, mold spores, pollen, bacteria, viruses, pet dander, and other pollutants damage your lungs and immune system. Unfortunately, most of these irritants cannot be seen by the naked eye. Air purifiers filter allergens and pollutants seen or unseen by the human eye. To remove these objects, air purifiers typically use filters, electrical attraction, or ozone.

Air filters utilize fine sieves that filter particles from circulating air. As air flows into the air purifier, the finer the sieve used, the smaller the particles it traps. The accepted benchmark for air filters has been set by the High Efficiency Particulate Air (HEPA) filters, which are guaranteed to trap 99.97% of airborne particles larger than 0.3 microns. Microns are the standard unit used for measuring air particles. Each micron is equivalent to 1/25,400 of an inch. The naked eye cannot see anything smaller than 10 microns, so pollutants like bacteria and viruses escape detection. Room air conditioner filters only capture particles 10.0 microns or larger. HEPA filters remove smaller allergens like dust, smoke, chemicals, asbestos, pollen, and pet dander. The more times the air passes through the HEPA filter, the cleaner the air becomes. The room capacity of a HEPA air purifier will determine whether the air cleaner can handle your air purifying needs. Top-of-the-line brands like Austin Air air purifiers will provide approximately 6 air exchanges per hour in an average room and contain an average of 15 lbs of activated carbon/zeolite blends, which adsorb chemicals and odors.

In addition to the HEPA filter, brands like NQ air purifiers offer an optional medical grade ultra-violet (UV) light system, used to quickly kill viruses, bacteria, and fungi upon entry into the air purifier. UV light also protects the HEPA filter from biological and viral contamination.clean air cool planet grant Electrical attraction is another technology utilized by air purifiers to trap particles. air cleaner for cat odorThree types of air cleaners work using electrical attraction: electrostatic precipitating cleaners, electret filters, and negative ion generators.where to buy air purifier shanghai Electrostatic precipitating cleaners or electronic air purifiers draw particles in by fan and charge them with a series of high-voltage wires.

Several plates (precipitating cells) carry the opposite electrical charge and attract the contaminants as they pass by the plates. Electronic air purifiers are perfect for individuals who don't want to worry about the costly replacements of HEPA filters. The downside to these units is that many create a nasty byproduct, ozone. Electret filters in air purifiers use synthetic fibers that create static charges to attract particles. Electret filters are offered in a variety of types including plain, pleated, disposable or reusable. Depending on the type of filter you need, will determine how often the filter requires replacement. Some brands like the Blueair air purifier combine the HEPA technology with their own electrostatic media filter technology, which charges the incoming particles instead of the filter. By marrying the two unique purification systems together, Blueair created a more effective air cleaner. Negative ion generators or ionic air purifiers use tiny, charged wires or needles to create gas molecules with negative charges or ions that adhere to the airborne particles and collect in the filter.

However, many ions end up back in the air, sticking to furnishings and other surfaces that may be stained by them. Ionic air purifiers only remove certain types of particles and aren't always effective against gases, chemicals, or odors. Some ionic air purifiers have been shown to re-circulate the same dirty particles that they draw in, making them much less effective than traditional air purifiers using HEPA filtration. Instead of using filters to trap particles, ozone generators use high voltage electrical currents to convert oxygen to ozone, which acts as a powerful oxidant and breaks down molecules and microorganisms in the air. Several tests have proved that ozone generators are not very effective at removing indoor allergens. Ozone, in fact, can be hazardous to your health, and both ozone generators and ionic air cleaners emit ozone. In nature, lightning creates ozone when it cuts through oxygen molecules in the air. In the atmosphere, ozone helps protect us from harmful UV rays;

however, on the ground level, ozone is a powerful lung irritant. When created artificially, ozone can actually aggravate allergies and asthma, damaging the lining of nasal passages and lungs, causing coughing, throat irritation, chest pain, and shortness of breath. does not carry them. Asbestos and radon are growing problems in homes today. Heating devices produce carbon monoxide and other dangerous gases, and chemicals like formaldehyde and ammonia are increasing in your home environment. Since most Americans stay indoors an average of 90% of the time, providing fresher and cleaner air has never been more important. Finding an environment-friendly solution has become much easier. Learn about air purification today. The right air purifier will provide asthma and allergy sufferers with air free from airborne pollutants and establish healthy indoor air quality for you and your entire family.In this article, we’re going to answer two of the most common questions people have about air purifiers:

We’ll explain everything you need to know about how air purifiers operate and what types of airborne contaminants they can get rid of inside your house. At its core, an air purifier is not too complicated to understand. In simple terms, these devices remove pollutants and allergens from the air so you don’t breathe them in. The benefits of having an air purifier are two-fold: The truth is that there are millions of microscopic particles floating in the air around you. With every inhale of your breath, you pull some of these particles into your lungs. If you have asthma or allergies, then you most likely notice the negative side effects of breathing in bad particles faster than someone who does not have these conditions. Unfortunately, no amount of daily dusting or vacuuming can ultimately fix this problem. In fact, these actions can actually make the problem worse by stirring up the harmful particles and pushing them back into the air. By adding an air purifier to your home, you can ensure that particles that cause breathing and health problems are eliminated from the airspace around you.

What you’ll notice that after using one inside your house is that you’ll have better sleep, an improved immune system, overall better feeling health. If you suffer from asthma or allergies, you’ll also notice a significantly less amount of asthma an allergy attacks. Now that you know what does a air purifier do, the next question you have is obvious, “How do they work?” This question is a little bit more complicated to answer, because some air purifiers use more than one type of technology to clean the air. The four major types of air filtration you’ll find on these types of products include: If an air purifier is built with a HEPA filter, it operates by pulling air into this dense, paper filter and trapping the particles within it so they can’t float back into the air. HEPA filters are great because they can to capture up to 99.97% of bad particles from the air. A carbon filter works by collecting pollutants that create smells and odors inside your home.

A HEPA filter cannot do this. If you want a fresh smelling home, getting an air purifier that includes a carbon filter is the best choice. An ionic generator is another type of technology that air purifiers may or may not use. This feature works by sending out ions into the air that latch onto harmful particles. This causes the pollutants to become very heavy and can’t remain in the air. These particles then fall to the ground or are become trapped in a collection plate that is on the device. The final type of air filtration you’ll find on an air purifier is Ultra Violet radiation. This non-lethal radiation is emitted from the device and attacks bacteria and viruses that are floating in the air. It works by breaking apart the molecular structure of these contaminants, which then renders them harmless to your health. This sums up the various methods on how do air purifiers work. As we mentioned above, some products include more than one or more of these features to strip the air from harmful particles.
