What Causes Indoor Air Problems?
Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants.
There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and outdoor sources such pollen, mold spores, pesticide, and outdoor air pollution.
When do you need an air purifier?
Many people may think that there are living in a clean home and feel relatively healthy, however the U.S. Environmental Protection Agency(EPA) has estimated that indoor air quality is 2 to 5 times more polluted than outside air. Thus you may find it difficult to believe that the indoor air quality in your home could be so poor and possibly hazardous to your health. So how do you know the truth? Few people have the time, energy, money, or motivation to seek out problems, so it's easier just to let the indoor air quality (IAQ) issue go and to think later about whether an air purifier or other remedy is needed for your long term health.
Since each person’s lifestyle is different and live in different environment, some people (especially one who is used to having an air purifier at home) may notice the slight smell of mold or mustiness, odor from cooking or tobacco, or if it's new, the off-gassing of new furniture when they enter to your home.
As you may see from these minor incidences of chemicals or particulates released into the air, none of them are consequential. The real problem is that they are released, day after day, year after year. It's the cumulative effect that eventually causes the indoor air quality to diminish more, but since the process is slow and subtle, we get used to it. It's this day to day build-up that a room air purifier can be used to eliminate.
If you have allergies, or even mild asthma, there's no doubt that an air purifier will help, particularly in the bedroom, so you can breathe easier when sleeping. If you've lived in the same house for years and go for long periods of time without opening all of the windows, there's no doubt you've built up toxins in the home. It's impossible not to. An air purifier will make a difference in the indoor air quality in your home, and thus in your overall health. Just as day after day, year after year, toxins build up, improvements in the quality of indoor air, nurture our health day after day, year after year.
