The noise that an air purifier gives off is considered ‘ambient noise’. Ambient noise, sometimes called “background noise,” refers to all noise present in a given environment, with the exclusion of the primary sound that an individual is monitoring or directly producing as a result of his or her work activities. Think of a coffee shop with a live band playing. The main sound is the music from the band, but there are other sounds happening in the background like the espresso machine and people ordering their coffee. Air purifiers work in such a way that they give off a noise, but it is in the background of our everyday activities in our home. Depending on the model and operating speed of the air purifier, the volume of noise given off can vary. An air purifier’s noise level is measured in decibels or dB(A) for short. The decibel, dB(A), scale is a logarithmic scale that goes up in powers of ten.
This unit of measurement is not just for marketing, it is rooted in mathematics for an applied practical approach. So for example, if an air purifier is marked as 50dB(A), it’s ten times louder than a 40dB(A) air purifier. Finding the quietest air purifier can be a little confusing since the noise is measured in both sound pressure and sound power of the unit. The sound pressure scale is lower than the sound power scale, and you need to know which decibel you are buying to get the quietest air purifier possible. So how loud are some of the common sounds we hear everyday in decibels?
Near-total Silence - 0 dB(A)
Whispering - 20 dB(A)
Clean-tech Air Purifier with Whisper Quiet Technology - 45db(A)
Normal Conversation - 60 dB(A)
Toilet Flushing - 75-85 dB(A)
Noisy Restaurant - 90 dB(A)
Baby Crying - 110 dB(A)
Jet Engine - 120 dB(A)
Balloon Pop - 157 dB(A)
It isn’t just the decibels that contribute to the noise level of an air purifier. The location of an air purifier can also have an affect on the noise level. For example, a room with carpet and furniture will help to absorb some of the sound rather than an empty room with tall ceilings and wood floors. When it is time to shop for a new air purifier, it is important to find out what the decibel rating is before purchasing. Since there is no requirement to list the noise emissions on air purifiers, products with no label could mean it is louder than you would like.
Most air purifiers on the market have multiple modes on which to run them. These modes usually have different noise levels and different functions. Clean-tech has two primary modes. The first is the Quick Clean Mode which turns the device to max speed for 2 hours. In this max speed setting, the decibel level is 58 dB(A) which is just below normal conversation volumes. The second is a Whisper Quiet Mode that's designed to operate 24/7. It has a decibel level of 45, equivalent to the ambient noise in a library. This makes it perfect for a bedroom. When leaving the room for the day, clicking on the Quick Clean Mode will ensure you have clean, breathable air when you return home. Leaving the unit running 24/7 will give you a quiet clean that won’t distract from any normal household activity. Not all air purifiers have these features or list the noise levels, so it is important to check these facts before purchase.
Air purifiers sanitize our indoor air to make it healthy and breathable. While maintaining a safe environment, air purifiers can eliminate many of the common contaminants in our air. Unfortunately, our outside world is riddled with pollutants. Just being inside is not an effective escape from these potentially harmful substances. Some people are even more susceptible to the effects of air pollutants, such as those who suffer from asthma and other sensitivities. With the addition of an air purifier, invisible contaminants can be destroyed before causing harm to the household.
Medical Grade UVC Air Purifier
Second hand smoke is highly toxic, even if you are just briefly exposed. It contains over 7,000 chemicals, 70 of which are known to cause cancer. Second hand smoke can drift in through windows, vents, and even cracks under the door. It is especially harmful and damaging to children and adults alike and causes over 41,000 deaths per year in the United States alone. An air purifier collects the toxic smoke particles in the air and traps them inside the HEPA filter. Those that escape the filter are then killed by the UV-C light.
Cleaning our homes or businesses is just a fact that we have to deal with. It seems like every day there is a new mess to clean up, another toilet to be scrubbed, or some windows to wipe. But cleaning with harsh chemicals can leave behind more than we bargain for. These fumes and particles linger in the air whether we can tell or not. Air purifiers suck in the polluted air and spit back out clean, sanitized air for us to breathe. Finally a cleaning partner that doesn’t complain!
Allergies are the 6th leading cause of chronic illness in the U.S. Seasonal allergies tend to strike during different parts of the year and are triggered mainly by pollen in the air. With the addition of an air purifier that is designed for allergy relief in the home or office, allergens will find themselves trapped in the HEPA filter maze or destroyed by the UV-C bulb.
The fact is, pets are part of the family! But most pets, cats, dogs, hamsters, and even miniature horses all have dander and odors. These odors can linger in our homes. Spraying aerosol air fresheners can only do so much and can’t get rid of the root problem. Air purifiers are known to trap dander and that pet odor to give us fresh breathable air.
Bedrooms are usually home to the highest levels of indoor air pollutants, including dust, bacteria, and even some viruses. Since we spend about a third of our days in bed, it is very important to keep the air in that room especially clean. This is the ideal location for an air purifier in the home but sound level may deter some people from placing it there. Opening a window may seem like a good option, but with the outdoor air pollution or even the temperature outdoors, it may not allow for this option. As we know, air purifiers help to remove indoor air pollution in a number of ways. From trapping dust and collecting particulates in a HEPA filter to sterilizing bacteria and viruses with UVC light, an air purifier can help to keep us safe in our home, especially when we are sleeping. A quiet air purifier is ideal for a bedroom environment, but there are a couple of things to look for when purchasing.
First, most models will specify how many square feet they cover, and will list its CADR, short for Clean Air Delivery Rate. The CADR will show the volume of air that the purifier will clean in an hour. Typically, the larger your air purifier is, the higher the CADR will be, though you probably don’t need a large model for your bedroom. Clean-tech is rated for a 200 square foot room and since it is a little different from a traditional air filter, its CADR rating is unique. Clean-tech both slows down the air inside of the UVC chamber to maximize UVC dosage and purposely allows particles through the pre-filter to be sterilized by the UVC. Additionally, through many tests and studies of air purifiers, there has been no direct correlation found between air purifier size and noise level.
