The indoor purification industry has certainly grown in the last several years. Concerns about outdoor air pollution have arisen, whether those concerns are valid or not, it is only natural that concerns about indoor air pollution are raised, and in some cases abused, by media manufacturers driven more by profit than safety.
There are currently two types of indoor air cleaners sold. Another type is the “ionic new air cleaner”, and there is another type that uses a HEPA filter. According to the Better Living Alpine Air site, the benefits of using indoor air purification systems include “reducing allergy symptoms like itchy eyes, difficulty breathing, runny nose.” First, we dispense with an “ionic” air cleaner. All ionic purifiers emit ozone. The EPA categorizes ozone as “good ozone” and “bad ozone.” If the only “good ozone” according to the EPA is the ozone in the atmosphere, the only “bad ozone” is that which is found near the ground, it follows that the ionic
So what about machines that use a HEPA filter? What is a HEPA filter anyway? First of all, the main difference between an air purifier that uses a HEPA filter and one that doesn’t is that a machine that uses a HEPA filter does not emit any ozone. To really understand what a HEPA filter is, HEPA is simply an acronym for “high efficiency particulate air.” When a HEPA filter is working properly, it is supposed to remove about “99.7% of airborne particles”. The science behind the use of HEPA filters in air purification is proven because HEPA filters are used in airplanes and hospitals where the air quality must be kept as disease-free as possible (http://en.wikipedia.org/. wiki/HEPA).
The problem with air purifiers that use HEPA through indoor filters is that the filter must be changed frequently to maintain optimal indoor air quality. While HEPA filter machines cannot emit ozone, it is their primary selling point according to air conditioner manufacturers. How often should filters be changed, you ask? This is where things get a little subjective. “About every six months,” according to Air Purifiers America, a seller of indoor air purification devices. According to this seller, how often you should change the HEPA filter “varies, depending on the brand and model.” And then this is a wise advice, while trying to understand the right time to change the HEPA filter: “Signs that necessarily include the replacement of the air filter: bad smell or odor from the unit, increased signs of dust in furniture or increased sneezing or coughing due to allergies (http://www.air-purifiers-america.com/replacement-air-filters.asp. ) It is entirely possible that one sense of smell to be different from another, doing the “bad smell” test recommended by Air Purifiers America, a completely subjective test when replacing the HEPA filter If the reason the consumer buys one of these air purification is primarily to help with allergies and remove air particles, what experiment It is necessary to determine if the sneezing or coughing has grown to the filter where it should be replaced?
What happened to just open the window if you want fresh air? The cost of these indoor air purification devices seems quite high. Air Purifiers of America is asking anywhere from $299 to $899 for one of these air purification devices. The filter and HEPA filters, which should be replaced about every six months, cost about $189 per filter, using the Air Purifiers America website. As a lot, it seems that pain in the mind is a medical problem. It is helpful to see some vendors selling air purification devices and models that ionically purify the air while also using devices that use HEPA filters, such as Better Living Alpine Air (www.betterlivingalpineair.com). The folks at Better Living also have “HEPA filter washers,” and say their HEPA filter machines can clean up to “3,500 square feet,” using what is called “UV-C Germicidal Technology.” The cost of these devices used to run around $1,299.00 for one of them, but Better Living seems to have altruistically reduced the price to just $339.95, and that includes “free shipping”. Frankly, these indoor air purification devices seem to be long on promises to “reduce allergy symptoms” and even “remove tobacco smoke” from the air, while the costs, which do not seem reasonable, are subject to the subjective nature of these devices. work That is, the quality of the air you breathe, after making a substantial investment in one of these devices, seems to be completely dependent on what you, the patient, perceive. Opening the window still seems to be healthier.
