Smoke Damage >> Air Cleaning Devices For The Home Fire

AIR CLEANING DEVICES FOR THE HOME Frequently Asked Questions. Many types of indoor pollution problems are found in homes. The most effective approach to solving these problems is usually to remove or reduce the sources of indoor pollution. Ventilation also helps remove indoor air pollutants, Air Cleaning Devices For The Home Fire but not as effectively as source reduction. 

Air cleaning devices (air filters and air cleaners) can also be helpful when used along with source reduction and Air Cleaning Devices For The Home Fire ventilation.The best solution to the air pollution within your home will depend, of course, on your particular problem, the effect it is having on your family's health, and your family’s budget. 

The information below will help you decide if an air cleaning device would be useful as a part of your solution to indoor pollution, and if so, what type might best meet your needs. Many of the principles discussed here also apply to offices, schools, and Air Cleaning Devices For The Home Fire vehicles. How Effective Are Air Cleaning Devices ?Air cleaning devices alone cannot adequately remove all indoor pollutants from homes. 

This is especially true when the sources emit a large amount of pollution, Air Cleaning Devices For The Home Fire or when the pollutants settle rapidly on surfaces. Most air cleaning devices will remove some of the particles from the indoor air,but will not effectively remove certain types of pollutants, such as carbon monoxide, radon, odors, lead dust, and allergens from mold, dust mites, roaches, and pets.

Air cleaning devices usually come as portable, stand-alone appliances, or as filters or cleaners in a central air system. Portable units can usually help clean the air in a single room, Air Cleaning Devices For The Home Fire while central air units may improve the air throughout the house.The health benefits of air cleaning devices are not clear, based on the very limited scientific evidence that is currently available. 

However, it is clear that you should never use an air cleaner that deliberately produces ozone (ozone generators). Ozone generators cause indoor pollution and do not clean the air, Air Cleaning Devices For The Home Fire as discussed later in this fact sheet. How Do I Improve My Existing Air Filters ? Central forced air systems in homes usually have a rectangular, one-inch thick fiberglass filter that slides underneath the furnace fan, or into a wall or ceiling register where the air returns to the furnace. 

These filters remove less than 10% of the very small particles that reach the filter. They are disposable and typically cost $2 to $3. Often, Air Cleaning Devices For The Home Fire merely upgrading this filter to a medium- or high-efficiency filter will help improve the air quality in your home. Medium-efficiency filters are typically pleated, woven material and are rated at 20-50% efficiency for removing particles of 0.3 to 10 microns (a micron is one millionth of a meter). 

They cost about $5 to $20, and both disposable and washable models are available. Some medium-efficiency filters use static electricity created by air flow, Air Cleaning Devices For The Home Fire but their effectiveness may decline as the static charge decreases over time.High-efficiency filters are rated at 60-95% efficiency. They cost about $20-$130, depending on whether they are disposable or washable. 

They are sometimes mistakenly called "HEPA" filters)True HEPA (High Efficiency Particle Arrestance) filters are 99.97% efficient, require very powerful fans, Air Cleaning Devices For The Home Fire and are rarely used in central forced air systems of homes. Proper installation, operation, and maintenance are critical for effective operation of air filters:

To maintain filter efficiency, Air Cleaning Devices For The Home Fire make sure that the filter fits tightly in its seat to prevent air from bypassing the filter. 9 Check the filter for dust and debris buildup at least every month during heavy use. Replace or clean the filter as necessary, based on the manufacturer's recommendations. 

To accurately show when a high-efficiency filter needs changing, Air Cleaning Devices For The Home Fire you may want to have an inexpensive pressure gauge installed; the filter manufacturers recommend maximum pressure drops for each filter model. Some filters or air cleaners come with a sensor that indicates when filter replacement is necessary.

To prolong the useful life of a high-efficiency filter, you may want to install a low-efficiency prefilter upstream in order to prevent rapid overloading of the filter.What Type of Air Cleaning Device Do I Need ?Even if you have taken actions to remove pollutant sources in and Air Cleaning Devices For The Home Fire near your home, provided ventilation, and upgraded your central air filters, you may still have a problem with excess dust or odors. 

If so, you may benefit from an air cleaner. The information below will help you determine what type and size of air cleaner you need, and how to use it properly. Air cleaners are available in different configurations: portable units for single rooms, Air Cleaning Devices For The Home Fire and larger central air cleaners for large rooms or the whole house. 

Smaller portable units typically cost between $50 and $200, Air Cleaning Devices For The Home Fire while larger or more efficient portable models typically cost over $300.Central air cleaners can cost on the order of $1,000 to $3,000, depending on the size and efficiency of the device.Most air cleaners remove particles, a few remove gases (and odors), and some do both. 

If you feel you have pollutants other than particles and dust that require removal, Air Cleaning Devices For The Home Fire consult a reference book such as the U.S. Environmental Protection Agency’s Introduction to Indoor Air Quality, A Reference Manual, or contact an experienced indoor air quality consultant. 

If you spend much time outdoors when levels of dust or allergens are high, Air Cleaning Devices For The Home Fire you should consider wearing a properly fitted dust mask designed for particles; contact the mask manufacturer for fitting instructions. PARTICLE REMOVAL. Some types of air cleaners can effectively remove particles such as dust and allergens from the air: mechanical or physical-barrier air cleaners, and electronic air cleaners.

Mechanical air cleaners. These devices draw air through a fibrous or metal filter with different sized pores that trap particles. These devices should use high- or medium-efficiency filters (see above). The filter will need to be sealed tightly in its seat, and replaced regularly, although some units have filters that can be cleaned and Air Cleaning Devices For The Home Fire re-used. 

These filters may be flat, round, or pleated.Electronic air cleaners. There are three general types of electronic air cleaning technologies: ozone generators, electrostatic precipitators (ESPs), and ionizers. Ozone generators produce ozone by design, Air Cleaning Devices For The Home Fire and are discussed later in this fact sheet. ESPs use a small electrical charge to collect particles from air pulled through the device. 

Ionizers, or negative ion generators, cause particles to stick to materials near the ionizer (such as the carpet and walls). Also available are hybrid air cleaners that have a combinations of technologies, Air Cleaning Devices For The Home Fire such as electronic technologies, mechanical filtration, or activated carbon, for pollutant removal.
