How they work
An air purifier with a HEPA filter is an option that many people use to remove dust from the air in their home. Air purifiers work by passing the surrounding room’s air through filters that collect particles and trap them, preventing those particles from being breathed back into your lungs.
The most common type of filter used in these systems is high-efficiency particulate arrestance (HEPA), which removes about 99.97 percent of 3 micron-sized dust particles, according to the Environmental Protection Agency (EPA). In addition to collecting airborne pollutants such as pollen, pet dander and mold spores,
HEPA filters can also remove gases like formaldehyde and smog chemicals such as benzene found in cigarette smoke or car exhaust fumes.
When you’re deciding on which model of HEPA air purifier might be right for you, consider how much space you have available: larger rooms require a more powerful unit to create enough suction power needed to pull all those particles out of the atmosphere; smaller rooms can be cleaned with a smaller, less powerful model.
Air purifiers create a negative pressure area in their immediate vicinity, which draws air in through the filter and pushes it out of the room. If you have allergies, asthma or other breathing problems that are triggered by airborne particles such as pollen and dust mites, an air purifier could help you breathe easier.
The main drawback to these units is the need for maintenance: they require filters to be replaced regularly — typically once every three months — so make sure to read reviews on any unit you’re considering buying before making your purchase decision.
Dose air purifiers help with dust or not?
Air purifiers are designed to remove dust and pollens from the air, but they use a variety of different techniques for this purpose.
Air purifiers can be separated into two basic groups: mechanical and electronic. Mechanical filters trap the large particles in the air (like pollen, dust or pet dander) while electronic devices attempt to neutralize pollutants with charged ions that cause pollutants to fall out of the air before it’s vented back into your home.
While both types are effective at removing airborne allergens from your indoor environment, only an electronic device is able to completely destroy germs and viruses by changing them into harmless substances like water vapor or carbon dioxide. In fact, some models even claim that their UV lights will kill mold spores as well!
Why you should care about dust in the air?
Dust is a major problem in many homes. The dust on your floors and carpets can cause allergies, respiratory problems, damage to your home’s belongings, and even lead to premature death.
Dust mites are microscopic insects that live in the most common places for humans: mattresses and carpets. They thrive on human dander (dead skin), which they excrete as feces or saliva from their mouths. Even if you don’t notice it, you’re breathing in this dust every time you go into your home! Will an air purifier help with ONGOING mold issues?
While a HEPA filter is an effective way to remove airborne allergens, it’s not the only way you can clean your home’s air.
Air purifiers don’t actually eliminate mold spores from the air. Instead, they are designed to trap them so that they don’t enter your body and cause health problems. The most common types of mold on indoor surfaces include:
Mold spores in carpet (often hidden beneath thick padding) Mold spores in carpets (hidden beneath thick padding) Molds in insulation and construction materials Mold growth inside ductwork or vents This list is by no means comprehensive — there are many types of molds that may lurk unseen within your walls.
While these molds may not be visible, mold can still be present and cause health problems for you and your family if left untreated! If you suspect that a problem exists, contact a professional for help with removing the affected area or having it cleaned properly.
Why does my air purifier constantly get dusty?
Most air purifiers are designed to remove airborne particles from the air, but they aren’t specifically engineered for this purpose.
As a result, most manufacturers recommend that you use your air purifier in conjunction with an HEPA filter or other type of vacuum cleaner. This will help to keep your unit clean and prevent dust build-up inside it.
How do I wash my air purifier?
Air purifiers are fairly simple machines — there’s not much to them! They’re easy to open, so you can just unplug one end and let the contents fall out into a bowl or bucket filled with water. You’ll also need some lint-free cloths to wipe down any parts that get dirty during cleaning (like the fan). Once everything is dry, plug it back in and enjoy fresh, clean indoor air!
Benefits of using air purifiers for dust
Dust is a mixture of particles and liquid droplets that can be found in the air. The main component of household dust are small particles less than 10 micrometers (µm) in diameter, which can get into your lungs and cause irritation.
When inhaled at high levels for long periods, exposure to these small dust particles may increase your risk for developing cardiovascular disease or aggravating lung problems such as asthma. Fortunately, using an air purifier to remove dust from indoor environments offers many health benefits: Fewer nighttime symptoms—especially in people with asthma.
Reducing the risk of cardiovascular disease —Research has shown that long-term exposure to airborne fine particle pollution accelerates atherosclerosis , hardening of the arteries due to plaque buildup, increasing one’s chances of having a heart attack or stroke.
Improving sleep quality Removing hazardous asbestos particles —Many older homes still contain asbestos insulation containing materials like vermiculite . Asbestos fibers are released when products made with them deterior ate.
What to look for
Air purifiers can be a good way to reduce dust in the home. These devices use filters, fans, and other mechanisms to remove particles from the air.
Most models rely on an electrostatic charge or a chemical process called adsorption to attract particles, but some also contain HEPA filters that physically trap them. However, people should avoid any device claiming to have negative ions as its main mechanism for reducing dust unless they know what kind of filter it uses—otherwise they could be breathing more particulates into their lungs than before.
The Environmental Protection Agency (EPA) recommends that consumers choose air purifiers with high-efficiency particulate air (HEPA) filters if they want something capable of removing airborne pollutants like pollen, mold spores , and bacteria .
This type of filter is capable of trapping 99.97% ±99% of airborne particles 0.3 microns in size —including most types of dust mite allergens . Other types include electronic air cleaners that aim electric charges atparticles, and ionic air cleaners that use positive or negative ions to attract particles.
Some purifiers have an antimicrobial effect on dust mites and other microorganisms by killing them with high-frequency sound waves —this is called a “negative ionizer.” However, these devices are not as effective at removing airborne particulates.
The EPA has also questioned whether they actually remove harmful particles from the air because they may be driven deeper into the home. In addition, some people have reported adverse health effects after using a negative ion device in their home for long periods of time.
Positive-ion air purifiers are similar to those that use electromagnetic fields to attract airborne particles and thus trap them in gas chambers—yet there’s no scientific evidence that these models provide any useful benefit over regular HEPA filters .
While it can be difficult to tell which air purifiers are actually worth the money, there are some simple things to look for when making your purchase. First, make sure that the device you’re buying is certified by UL (Underwriters Laboratories) or CSA (Canadian Standards Association). These organizations test devices for safety and performance in order to ensure manufacturers meet certain standards.
Next, make sure that your device has a high-quality filter. A good filter will have an efficiency rating of at least 99%—but even if the rating isn’t as high as you want it could be much higher than advertised due to improper testing methods used by manufacturers.
Last but not least, always read reviews before purchasing any product online or in person and keep in mind that positive ionizers may not provide long-term health benefits over regular HEPA filters .
