What's the best air purifier for allergies ? A common mistake is assuming that online ratings and reviews tell the whole story. Even though most sites will tell you that a HEPA air purifier is the best air purifier for allergies HEPA will not take every allergen out of the air. As a former allergy and asthma sufferer (and Health Practitioner) I can tell you that each of the ten types of air purifiers do something different when it comes to allergies.
NOTE: If you don't know the 10 air purifier technologies I suggest you watch the video.
HEPA - For removing dust, pollen, and animal Dander
Ultraviolet Light - For killing germs, bacteria and mold
Carbon - For absorbing chemicals, odors, and gases
Negative Ion - Supports healthier air, kills mold, and is known to help asthmatics breathe easier
Electrostatic - Kills smoke and odors but is not effective for dust or pollen
Tio2 - Enhances UV light many times to support the immune system
I often suggest to people that they look for air purifiers that include at least HEPA, UV, Negative Ion and Carbon. These 4 technologies will cover most allergy-related problems.
Ok. Since I mentioned the liver I must explain myself. The Left lobe of the Liver handles many of the toxins we breathe in or ingest. The body has to get rid of these toxins and the Liver has the job of processing them. If the liver gets overwhelmed and cannot do the detox it stores these toxins or chemicals. It also creates histamines to help the body deal with toxins. Too many histamines = more allergic responses.
The more pollutants you can remove for the air the easier it is on the liver and immune system. Overtime this reduced load on the liver can help reduce allergic reactions and also makes for a stronger immune system.
The best air purifier for allergies is the one that removes both your primary trigger for allergies as well as the secondary problems which can weaken the immune system and cause more allergic sensitivity. So for example if you allergy is to pollen then a HEPA filter is a good technology to have, but because most people allergic to pollen are also allergic to mold then including Ultraviolet light and/or negative ions to kill mold would prevent secondary allergic responses.
