Frequently asked questions about Air Purifiers.
My air conditioning system has an air filter on it, do I need anything more?
Traditional air filters only trap medium-to-large particles and has no effect on gases, vapors, bacteria and viruses.
Is there such a thing as a sick home?
Sick home syndrome is one in which occupants suffer from acute health and comfort disorders. Common complaints include sore throat, headache, itchy eyes, fatigue, coughing, wheezing, itching, and nausea, which are often linked to the time spent in the home, but no specific cause of the illness can be identified.
What causes sick home syndrome?
As explained in this review, sick home syndrome is caused by toxins such as formaldehyde, VOC and combustion gasses getting trapped inside and not being diluted or flushed out of the home by fresh air.
What is UV light?
Ultraviolet (UV) light is an invisible form of electromagnetic radiation that has a shorter wavelength than the light humans can see. The term “ultraviolet” means “beyond violet.” In the visible part of the spectrum, wavelength decreases from red through orange, yellow, green, blue and violet, so UV is “beyond” violet in the spectrum. This form of light — which is present in sunlight — can be beneficial to health, as it stimulates the production of vitamin D and can kill harmful microorganisms, but excessive exposure can cause sunburn and increase the risk of skin cancer. UV light has many uses, including disinfection, fluorescent light bulbs, and in astronomy.
How is UV light used in an Air Purifier?
Ultraviolet (UV) light is used to sterilize or kill airborne microorganisms. Air passing through the air purifier is bathed in UV light. Any microorganisms in the air are killed or sterilized by the UV light. UV light has little to no effect on gases, vapors, or odors.
Is a UV light effective enough on its own?
The combination of UV light with other filtering techniques can be more effective. Remember that UV light primarily deals with microorganisms and has little or no effect on particles. An Air Purifier that uses both UV light and filtering may be more effective at combating a variety of contaminants which is better than UV alone.
Are UV-C – Germicidal Lamps a less expensive option?
These are rapidly becoming very popular as an easy fix for the air conditioner coil mold problem. This is one of the most prevalent causes of the mildew smell you get when you enter an air-conditioned home. These lamps are similar to sun lamps and are only effective on microorganisms that pass by within a few inches of the lamp.
What is ozone?
Ozone is a gas that is highly reactive. It can be very effective on gases, vapors and odors. There is a considerable amount of controversy over the use of ozone in Air Purifiers. Some studies have shown that ozone can cause health problems and react with materials in the home. Other studies have shown that ozone is safe. From a maintenance perspective, some methods of producing ozone have maintenance problems and introduce gases other than ozone into the home. If you decide to use an ozone based air Purifier be sure to check the facts and make sure that ozone is right for you.
Is ozone good in treating people with asthma and emphysema?
Persons suffering from chronic breathing problems are well known to be sensitive to ozone. Air purified with ozone is certainly better than dirty air for asthma sufferers; however one must be sure to take into consideration the potential consequences of using ozone. In this regard, always consult a licensed medical practitioner before making any decisions about ozone.
Do Air Purifiers remove mold?
Some air purifiers may effectively remove mold particles from the air but are ineffective against killing mold spores. However, if spores become trapped in a filter, this does keep them from proliferating in your home. In order to combat mold in your home you must eliminate the causes of mold. An example would be an area that was damaged by water from a burst pipe. Once the mold had been eliminated an Air Purifier can help to trap and eliminate any spores in your home.
Do Air Purifiers combat allergies caused by pets?
Some Air Purifiers remove pet hair and dander trapped in the air. Heavier pet dander particles often fall out of the air and settle onto surfaces. Only frequent use of vacuums and regular surface wiping will remove them. No one can say that an air purifier will completely stop allergies; however it will reduce the amount of stimulants in conjunction with making proactive living style changes, such as keeping pets out of sleeping areas to avoid contact with pet dander at night, which may lead to more comfortable sleeping conditions.
Do Air Purifiers help with allergies?
It depends on the source of your allergy. According to the Mayo Clinic, allergies can be caused by various pollens, fungi and mold spores, dust mites or cockroaches, and pet dander. Air Purifiers can be effective at removing these types of particles from your home. Dust mite feces, cockroach body parts and pet dander are typically heavier particles that fall out of the air and must be cleaned from surfaces. Use allergen covers on bedding and pillows to protect against the most common exposure to dust mites.
