The Benefits of Using an Air Purifier
Let's start with the basics... Why would you even need an air purifier if your HVAC system already includes a filter? Doesn't that already take care of all contaminants? The answer is no...
Unlike an air purifier, the primary purpose of an HVAC filter is to keep your system components clean, NOT remove particles and pollutants that can make you sick. Only an indoor air cleaner can remove these sometimes harmful substances and help relieve you of allergies, respiratory issues and other health-related problems (source).
So what are these potentially damaging air pollutants? Well, they fall into two main categories: particulate matter and gaseous pollutants. Particulates are usually tiny organisms or substances such as:
- Animal dander
- Dust and dust mites
Gaseous pollutants, in contrast, are fumes emitted during use or through the manufacturing process, including:
- Building materials
- Carpets and furnishings
- Cleaning products
- Tobacco smoke
Depending on your bodily constitution and susceptibility, either type of pollutant has the potential to cause health problems, especially when exposed over long periods of time.
Now, as you'd expect, not all air cleaners are the same. Their effectiveness depends on how well they extract pollutants from the air AND how much they draw through their cleaning components. In other words, air cleaners need both a high air circulation rate and an efficient collection system to be effective.
Why Use an Air Purifier In Your Bedroom?
When you consider the average person sleeps between seven and eight hours per night, plus time spent preparing for bed and getting ready the following morning, you're looking upwards of 10 hours per day in your bedroom — that's probably more than anywhere else in your home! (source). Thus, it only makes sense to try to create the healthiest environment possible in the place where you spend it the most.
Now, contrary to what you might think, bedrooms can be breeding grounds for all sorts of potentially harmful substances. For example, does your pet sleep with you? If so, he/she can shed dander on your sheets, which can cause asthma and other medical conditions (source). Moreover, pets can drag in pollen, mold spores, and other particulates from outdoors — all possible allergy triggers.
And while you might not be rolling outside in the grass, you can pretty much bet you also carry in microscopic particles (albeit through clothing, not fur). And don't forget all the dust and dust mites collecting in corners where even your vacuum can't reach.
Then there's the question of gaseous pollutants. If you use cleaning sprays and other household cleaning products to help maintain and protect your bedroom furniture and fabric, no doubt you're inhaling that too! (source).
Thus, it's no wonder why some people wake up coughing in the middle of the night and experience stuffy noses the following day when you consider the sheer amount of pollutants in the air. Luckily, an air purifier in your bedroom can put a halt to all that.
How to Choose an Air Purifier for Your Bedroom
Now that you know some of the ways air purifiers aid sleep, how do you go about selecting one? Well, there are a few key features to pay attention to, depending on your preference:
HEPA Filter – Most allergists recommend choosing an air purifier with a HEPA filter over other kinds (High-Efficiency Particulate Air). This type of filter is supposed to remove at least 99.97 percent of particles as small as 0.3 microns, allowing it to trap most common particulates. The bigger the size of the filter, the more pollutants it's able to get rid of (source).
Air purifiers that don't use HEPA filters often use ionization to trap charged particles instead. While effective, these types of air cleaners emit ozone, which may cause adverse reactions in people with heightened sensitivities.
Gaseous Pollutant Removal – An air purifier should also be able to eliminate odors, such as tobacco smoke and other gaseous pollutants. While HEPA-certified devices include a charcoal filter for this purpose, ionizers work better in this regard. Thus, regular smokers should prioritize ionizers over HEPA-certified air purifiers when shopping around.
Ultraviolet (UV) Light Technology – Also known as ultraviolet germicidal irradiation (UVGI) cleaners, these types of air purifiers use UV radiation to help destroy airborne viruses, bacteria, allergens, and molds.
Aside from these factors, you also want to make sure to select an air purifier large enough to capture particles from every corner of your bedroom. For a better idea of how airflow technology works on these devices, check out the video below:
Reviews of the Best Air Purifiers for Bedrooms
To help you with your selection, we've reviewed five of the best air purifiers for your bedroom below:
Key Features: HEPA filter, UV Light Technology
Featuring a true HEPA filter, odor reduction capabilities, and UV light to help eradicate bacteria and viruses, this GermGuardian unit is a true star among portable air purifiers. And unlike some models, this unit is truly quiet, making it the perfect device for sleep.
Moreover, its 22-inch tower frame and three-speed fan are powerful enough to accommodate the air purification needs of most bedrooms. Thus, those wanting to rid odors or particulates to ease asthma, allergies or respiratory issues will get much mileage out of this product.
Key Features: HEPA filter, Ionizer
Despite its small size, this air purifier packs a wallop with its five fan settings, four-stage filtration system, and 360-degree cleaning capabilities. And unlike some air purifiers, this unit isn't an eyesore. In fact, its sleek, innovative table-top design will likely complement your bedroom, not detract from it. Plus, you have a choice between a white or black panel color.
Combining both a HEPA filtration system and ionizer, the Coway is among the best devices to collect pollutants and keep your indoor air clean. But quality at this level comes at a cost, which may or may not be within your price range.
Key Features: Ionizer, UV Light Technology
If your primary purpose for an air purifier is to remove odors, this unit may be your best pick. But as an ionizer, it's not the optimal choice for those suffering from severe allergies or respiratory problems since it may not remove as many particulates as a HEPA filter unit can. That said, it does include UVGI technology to help destroy airborne pathogens, just not as well as a HEPA filtration unit.
This device is relatively inexpensive even after factoring in upkeep and energy costs and thus a good option for those on a budget.
Key Features: HEPA filter, UV Light Technology
The convenient, compact design of this unit makes it an appealing choice for smaller-sized spaces especially (5 to 8-foot radius). Despite being a table-top model, its three-speed motor still packs a powerful punch by removing almost all particulates in its surrounding area.
The unit is somewhat louder than others on our list, but not to the extent that it would keep you awake at night. Being a HEPA-based device, it doesn't emit ozone which might trigger symptoms. In short, this unit is worth a look for smaller-sized jobs.
Key Features: HEPA filter
Like the Coway AP-1512HH and GermGuardian AC4100 air purifiers, this is another prime example of a top-notch, table-top unit. Its quiet operation, low power consumption, wide coverage (up to 700 feet), and thin, sleek design are all strong selling points. But its customizable features really set this product apart, namely its four types of filters to choose from and 14 different panel color options.
All these perks come at a steep price, which may be cost prohibitive for some people. Still, it's easy to see why many consider this device the gold standard.
What Is the Best Air Purifier for Your Bedroom?
When taking into account quality, price, effectiveness, and other metrics, our top choice goes to the GermGuardian AC4825 Air Purifier. While not the sleekest, most modern design, this unit does what a first-class HEPA air purifier should — eliminate odors and particulates to relieve you of allergies, asthma, and respiratory problems for a more restful night of sleep.
