Filters for indoor pollution from California wildfires

Many Californians are rightly concerned about how the wildfires sweeping across the state are impacting their indoor air quality. Wildfires create what's known as PM10 -- particles fewer than 10 microns in diameter. These particles are small enough to be inhaled deep into the lungs, where they evade the respiratory system's natural defenses and could possibly trigger health problems.

PM10 can increase the number and severity of asthma attacks, cause or aggravate bronchitis and other lung diseases, and reduce the body's ability to fight infections.

Certain sensitive populations (including individuals with asthma or other respiratory diseases, individuals with cardiovascular disease, the elderly, children and smokers) are susceptible to more serious symptoms, including cough, phlegm, wheezing, shortness of breath, bronchitis, increased asthma attacks, and aggravation of lung or heart disease. Some sensitive people might experience health problems after even short exposures to fine particles, such as several hours or a day.

However, some air purifiers can help alleviate these issues, particularly those with HEPA filters that are capable of removing 99% of common household particles such as smoke, dust, pollen and cat dander. True HEPA air purifiers can help capture particles as small as 0.3 microns from the air passing through their filters. Each model features a fan to circulate the air, helping to pull the air in, filter it and release fresher, cleaner air into the room. In addition, independent lab tests have proven True HEPA air purifiers help reduce airborne bacteria, mold spores and fungus. Featuring carbon activated pre-filters, these units will also help reduce smoke odors.

It's recommended that air purifiers are placed in the areas of the home where people spend the most time, such as bedrooms and living rooms.
