There is a clue in the name of what they are doing, but can air purifiers also help with stench? As concerns about indoor and outdoor air pollution grow, the market for air purifiers is expanding and more and more research is being done on how air purifiers can help reduce viruses in the air. CDCIt’s no wonder it’s becoming more popular.
Air purifier manufacturers claim that improving air quality can remove odors from the environment. Is this really true? We look at research on air purifiers to see if there is enough evidence to prove that air purifiers can really tackle and get rid of the stench in our homes.
Can an air purifier really mitigate bad odors?
The jury seems to be out for the time being.according to US Environmental Protection Agency (EPA), removing air pollutants in the room can make the air cleaner and fresher, but it is not guaranteed to work against all odors and protracted odors.
EPA 2018 Consumer Guide for Household Air Cleaners An indoor air purifier is recommended as an auxiliary method, along with good ventilation, to keep the room air fresh, remove odors and improve air quality. So it’s not a panacea for an odorless home, but it may help improve the surrounding environment when working indoors.
There are not many reliable studies on odor removal and air purifiers. Most of the studies available focus on air quality and health results.For example, a systematic review of 2021 Science of Comprehensive Environmental Journal In more than 20 studies on the effectiveness of air purifiers in schools, homes and offices, we found that these appliances can reduce the poor air quality in the room by 22% to 92%. NS 2020 study International Journal of Environmental Research and Public Health It has been found that air purifiers cannot improve the indoor environment of a normal home slightly but significantly.
Air purifiers work by filtering and removing particles that can cause foul odors.However EPA It states that there is no air cleaner or filter that can remove all particles that can cause foul odors.
Air purifiers tend to work best in one room, so if you want to get rid of bad odors from your home, one air purifier isn’t enough. The larger the area you are working on, the larger the air purifier will need to be. Air purifier with high CADR (clean air delivery rate)) You can filter more particles to work on a wider area.
What kind of odor does an air purifier help?
This may vary depending on the air purifier you are purchasing.according to EPA, Some air purifiers can tackle musty odors, alongside regular cooking odors, pet odors, cigarette smoke, and other protracted scented criminals.
Some air purifiers also have activated carbon filters and particle filters. This means that you can deal with the gases and chemical odors that can come from building materials, pesticides and flame retardants.
How does an air purifier get rid of odors?
Air purifiers work by using a fan to draw allergens from the air. The exact particles they remove depend on the type of air purifier.
Some purifiers use negative ion emission techniques that help attract particles.However EPA These air purifiers warn that they can release ozone emissions to the home, which is a health risk. NS California Aviation Resources Commission We also recommend that you do not use ozone generators at home due to health risks.
Most air purifiers typically use filtering techniques to capture polluted particles and gases from the air. Washable or disposable pre-filters catch pet fluff, hair, and other larger particles. Remember to follow the manufacturer’s instructions for replacing or cleaning this filter.
Small particles that pass through the pre-filter are captured by a highly efficient particulate air (HEPA) filter composed of layers of glass fiber threads. When the particles are drawn in, they are trapped in this high density mesh.
However, it is worth knowing that quality of HEPA filters designed for home use can vary from product to product, as there is no widely accepted definition of good performance. It should also be replaced according to the manufacturer’s guidelines.
Some air purifiers also have a vapor phase air filter. It uses materials called adsorbents, such as activated carbon, to absorb harmful gas pollutants as they pass through. It is worth knowing that these filters can usually remove only a limited number of gas pollutants. NS EPA Carbon monoxide, a dangerous gaseous pollutant, is currently not absorbed by residential air purifiers, he said. Therefore, if you are burning a wood stove, gas fire, or kerosene lamp, the air purifier will not capture the carbon monoxide it emits.
Some air purifiers use UV technology to destroy indoor air pollutants such as bacteria and viruses, and allergens such as mold spores and pollen. However, many bacterial and mold spores require more exposure to UV light than these devices actually provide. EPA.. Therefore, it may not be as effective as the manufacturer claims.
