This wiki has been updated 20 times since it was first published in March of 2015. Airborne particles, bacteria and other contaminants can pose a variety of health risks, particularly to asthmatics and people who suffer from allergies. These air purifiers remove things like pollen, dust and smoke from the air, making your home a safer and healthier place in the process. Some of these models are designed with HEPA filters and other advanced technologies as well. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.

Hathaspace Smart This model utilizes an innovative six-stage purification process, pushing the air through four separate filters to remove large particles, tiny viruses and everything in between. It will replace the air in a 350-square-foot room two times per hour, and it operates at only 18 decibels in quiet mode. hathaspace.com

The Alen BreatheSmart is the ringleader of the three new additions to this list. As one of the only models available with a wide variety of design options, you have the freedom to choose the style that best matches the décor of your home or office. Even after a short period of operation, users have indicated a noticeable reduction in the amount of airborne allergens and dust present in the air, in many cases across an entire apartment.
Also added the Hathaspace Smart in the Special Honors category, which is a good value for use in normal-sized rooms. Pet owners appreciate its ability to remove dog odors, and many seem to like the option to turn off the ionizer function if desired. Moved the Pure Enrichment PureZone down a couple of spots. While it’s effective in small rooms like bathrooms or compact offices, its usefulness is limited in more spacious areas like kitchens and living rooms.
Removed the Winix Ultimate due to a lack of availability and the GermGuardian Elite as it is an outdated product (with a new version available that does not meet quality standards). Also eliminated the Airmega 300S after discovering a plethora of user complaints, particularly regarding its mobile app and WiFi capabilities. The app is not intuitive, shows little useful information, and does not operate smoothly. As an air purifier, it appears to work adequately, but when people pay a premium for smart features, those features need to function properly to provide value.
How Do Common Air Purifiers Work?
While they all may seem like recent developments; some air purification systems have been around for centuries.
Patients with allergies in the fall or winter months and/or perennial allergic rhinitis were the most commonly studied.
There are many different air purifiers in the modern era. While they all may seem like recent developments; some air purification systems have been around for centuries. The most common name in the realm of air purifiers is the HEPA system. The HEPA system has enjoyed recent popularity, but it was actually developed in World War II. An abbreviation for high efficiency particulate air; HEPA filters were originally designed to remove radioactive waste materials and dust particles from the air to protect soldiers' respiratory systems.
UV light systems are also popular air purification options. Medical grade ultra-violet light can quickly kill bacteria, viruses, and fungal spores as the air circulates through the filter, protecting both the room and the filter itself from mold inoculation and microbial buildup. Another type of air purifier uses electrostatic precipitators which harness an electrical charge to remove particles from the air.
Carbon filtration may be one of the most simple systems, yet its effectiveness is unquestioned. Carbon filtering is the process of pushing air through a bed of activated carbon to remove impurities. Activated carbon is highly absorbent due to its large surface area. It is said that one teaspoon of activated carbon has the surface area of an entire football field. This surface area allows activated carbon to cling to and absorb a large number of contaminants.
The question remains, are air purifiers effective? From a scientific standpoint the answer is a resounding yes. In multiple studies considering the effectiveness of air purifiers in treating patients with allergic rhinitis and asthma, research suggests that purifiers successfully reduce allergic respiratory symptoms to various degrees. Patients with allergies in the fall or winter months and/or perennial allergic rhinitis were the most commonly studied. In rooms with active air purifiers, there was a seventy percent reduction in airborne particulates on average. The absence of respiratory infection coupled with patients' suggestive responses showed a high degree of effectiveness using air purifiers.
Is It Possible To Treat Allergies With Your Diet?
While air purifiers are a must have for anyone suffering from allergies, asthma, or seasonal rhinitis, many look to supplement this treatment through their dietary intake. The possibility of dietary influences to respiratory conditions cannot be overlooked, Many of the aggravating factors of these conditions exist within various foods. Can a simple change of diet help ameliorate symptoms of allergies and asthma?

Recent published studies have indicated that probiotics may be a successful secondary treatment to allergies. Beneficial bacterial strains include Lactobacillus acidophilus and Bifidobacterium longum, which traditionally inhabit the human digestive system. Largely due to over-processed dietary intake, pasteurization, and antibiotics, the presence of these beneficial microbes in the average human is dwindling.
The ingested live microbes can modify the composition of the intestinal flora in a way that benefits the host. Reintroduction of these bacterial strains through probiotic supplementation shows many benefits, such as properly equipping the body's immune system to reduce allergic reactions and asthmatic symptoms.
The clinical benefit of probiotics depends upon numerous factors including the type of bacteria, dosing, delivery method, and the age and overall diet of the host. For instance, a host eating a western pattern diet will find much less benefit than one who eats a well balanced diet comprised of unprocessed foods.
Why Is There A Need For Air Purifiers?
The prevalence of respiratory disorders such as allergic rhinitis and asthma continually increase worldwide. The World Health Organization estimates over 700 million people are affected by these respiratory illnesses.
As the severity and complexity of respiratory diseases continues to grow, patients and health practitioners alike look for effective solutions.
As up to ten percent of the world's population is affected by allergic rhinitis, it the most common form of non-infectious rhinitis globally. Allergic rhinitis is, by simple definition, the presence of nasal congestion, sneezing, itching, and inflamed nasal mucosa. The severity of allergic rhinitis differs in patients, ranging from mild to near debilitating levels. Asthma is a condition marked by spasms in the bronchi of the lungs, which causes breathing difficulties. Asthma is usually connected to an allergic reaction to airborne pollutants or hypersensitivity to particles in the air.
Allergies or asthma can have a severe impact on a patient's quality of life. The symptoms can impact relationships, work life, physical function, mental cognition, and psychological feelings of wellness. Secondary disorders caused by allergies and asthma include sleeping disorders, learning and attention impairment, mouth breathing and associated dental malocclusion, and increased risk of upper respiratory infection. As the severity and complexity of respiratory diseases continues to grow, patients and health practitioners alike look for effective solutions.
Now more than ever, patients have the ability to reduce their symptoms by reducing airborne irritants with an air purifier. Allergens such as bacteria, viruses, fungal and mold spores, pet dander, pollen, and chemical pollutants can take a toll on anyone's respiratory system, not just those with allergies. As most of these pollutants are not seen by the naked eye or absorbed by anything around the home, the best way to remove these potentially harmful substances is through the use of an air purifier.
