Smoke Damage >> How To Remove Smoke Damage From Furniture

Both ESPs and ionizers produce ozone as a by-product of the ion-generating technology they use.Another type of electronic air cleaner technology, photo catalytic oxidation (PCO) with ultra violet light, has recently entered the market, How To Remove Smoke Damage From Furniture but is not very common yet. All of these electronic technologies can produce significant amounts of ozone that result in unhealthful indoor air quality and a pungent odor. 

To minimize ozone emissions, these devices need to be cleaned and maintained regularly, and operated only according to the manufacturer's instructions.GAS REMOVAL. Residential air cleaning devices that remove gases and odors are relatively costly, How To Remove Smoke Damage From Furniture both to purchase and maintain. Gaseous pollutants are typically trapped or destroyed as the air is drawn through materials such as activated charcoal or alumina coated with potassium permanganate. 

However, the filter material can become quickly overloaded and may need to be replaced often. These filters (usually charcoal) are offered as an option with some residential particle air cleaners. If you have very sensitive individuals in your home or How To Remove Smoke Damage From Furniture odors that are difficult to remove, especially in just one area of the home, you may want to consider this option. 

However,in most homes, How To Remove Smoke Damage From Furniture a particle filter is all that is needed. PORTABLE AIR CLEANERS. Portable air cleaners are practical for existing homes where addition of a central air cleaner is too costly. Proper size, installation, and maintenance are critical for portable air cleaners to be effective. 9 Check the room size rating (in square feet of floor area) for the air cleaner, and use the appropriately sized unit for your situation. 

You can also use the How To Remove Smoke Damage From Furniture Appendix to this fact sheet to determine size requirements. 9 Install the unit(s) in the room(s) where you spend most of your time or have the worst symptoms.9 Locate the unit away from doors, windows, and foot traffic, but not close to walls or corners, so that air may easily reach the air cleaner.

CENTRAL AIR CLEANERS. Central air cleaners can also be added to conventional forced air systems in new or existing homes. However, How To Remove Smoke Damage From Furniture a more powerful fan may be required to move sufficient air through some types of air cleaners. In addition, energy costs for constant fan operation can be significant. 

Alternatively, some manufacturers produce forced air systems that have a two-speed or variable speed fan, so that the system can operate at a lower fan speed when a lower rate of air cleaning or fresh air ventilation is needed. Access for maintenance also can be problematic. In addition, How To Remove Smoke Damage From Furniture these systems do not normally come with an outdoor air supply, so further modifications may be needed. 

For new homes or How To Remove Smoke Damage From Furniture major remodels, "whole-house" or "fresh-air" ventilation systems that also provide some filtration can be installed separately from the central heating and cooling system.These systems typically use an air filter, small diameter ducts, a quiet energy-efficient fan, and a heat- recovery ventilator (optional). 

Installed costs are about $1,200 or more, depending on the system size and How To Remove Smoke Damage From Furniture the type of air cleaning device. Fresh-air ventilation systems are recommended in new,tightly built energy-efficient houses, and for situations where the outdoor air is the major source of indoor pollution.To design and install any central system air cleaner, contact a company or contractor that is experienced in designing and installing central filtration systems. 

Request a system that is low leakage, easy to maintain, and How To Remove Smoke Damage From Furniture energy efficient. What Size Air Cleaner Should I Get ? The effectiveness of some portable air cleaners in removing particles is usually rated in terms of pollutant removal efficiency, or Clean Air Delivery Rate (CADR), measured in cubic feet per minute(cfm). 

The CADR equals the airflow (cfm) multiplied by the efficiency of particle removal; a larger CADR is better. The CADR ratings are given separately for the removal of dust, pollen, and How To Remove Smoke Damage From Furniture environmental tobacco smoke.For air filters in forced air systems, it is most appropriate to use test ratings that are based on particle sizes smaller than ten microns. 

This particle size range is of the greatest health concern.Test standards for particle removal by air cleaning devices have been developed by trade and How To Remove Smoke Damage From Furniture engineering groups, but standards for gas removal have not been developed.Larger air cleaners usually produce more noise and use more energy than smaller units do. 

For these reasons, you should avoid getting an air cleaner that is over sized for the room(s) you are cleaning.PORTABLE AIR CLEANER. Select an air cleaner that can replace the room air at least two or three times per hour, How To Remove Smoke Damage From Furniture enough to rapidly reduce indoor pollutant levels. Most portable units will state on the package the unit's air flow rate (in cfm), the size room it cleans, and perhaps its particle removal efficiency and its CADR. 

The appropriate size for a portable air cleaner can then be calculated following the formula and How To Remove Smoke Damage From Furniture example shown in the Appendix.CENTRAL SYSTEM AIR CLEANER. Size the air cleaner to handle at least 0.5 air changes per hour (see Appendix). This is the air exchange rate (AER) necessary to continuously ventilate a house under most conditions. 

To avoid major air flow (and energy) loss, have your system's ductwork pressure tested for leakage and then sealed and How To Remove Smoke Damage From Furniture insulated as necessary. Where Can I Buy Air Filters and Air Cleaners ?Most department, home supply, hardware, and discount stores now offer several models of portable air cleaners and central system air filters of varying efficiencies. 

Allergy supply stores, drug stores,and medical supply businesses also typically offer several models. Air cleaners and replacement filters also can be ordered on the Internet. Central air cleaning systems should be designed and installed by an experienced, How To Remove Smoke Damage From Furniture licensed mechanical contractor or heating and ventilating contractor. 

What Types of Air Cleaners Are Not Effective ? OZONE GENERATORS. The California Air Resources Board, the California Department of Health Services, and How To Remove Smoke Damage From Furniture other government agencies advise the public not to use so-called "air purifiers" that are specifically designed to generate ozone indoors (see references below). 

These ozone generators are sometimes marketed as emitting "trivalent" oxygen, "activated" oxygen, "allotropic"oxygen, "saturated" oxygen, "superoxygen," or "mountain-fresh air." These devices may also becombined with an ionizer or How To Remove Smoke Damage From Furniture other technologies. However, these devices are actually emittingozone.
