Indoor Air Quality and Central Vacuum Systems

In general the quality of the air inside most homes is poor as a result of the same air being constantly re-circulated by the heating and cooling systems.  This air often contains moisture, insects, dust mites, pollen, dander, fumes from household products and furnishings, smoke, dirt, cooking fumes and germs.  Often these terms negatively impact asthma and allergy suffers and can trigger symptoms.  While it is possible to improve indoor air quality by modifying the heating and cooling system with special filters and introducing outside air into the homes, studies have shown that a central vacuum system will significantly improve the symptoms in people suffering from allergies and asthma. 

Central vacuum systems are a cost effective system integrated into the structure of the home.  Typically they consist of a series of outlets in the walls of the home that will accommodate a series of specialized cleaning tools.  The outlets, which power the cleaning tools using a built in power source, are connected to a central vacuum unit located in an unused part of the home, by a series of pipes.

The vacuuming process is basically the same as a traditional vacuum, with the remotely located unit collecting the large materials.  However, unlike traditional vacuum cleaners, the air is exhausted to the exterior of the home and not to the interior of the home.  This keeps the smaller airborne particles from continuously being re-circulated.  This provides continuous improvement in the indoor air quality of the home, while also significantly improving the quality of life of those suffering from asthma and allergies!

Types of Central Vacuum Systems

A central vacuum is a type of home filtration system that improves interior air quality by removing dust, allergens, and waste particles from indoor air. Compared to the portable vacuum cleaners that are used to clean floors and carpets, stationary central vacuum systems keep rooms cleaner; they filter air by depositing dust and dirt in a disposable bag or canister thereby minimizing the amount of dust that re-circulates back into the living area.

There are three types of central vacuum systems:

  1. Paper/cloth bag

Disposable paper bag systems are the most common type of central vacuum unit. Dust and airborne waste (mold spores, pet dander, lint, bacteria, dirt, fabric fibers etc.) are suctioned into the system via outlets located in each room and deposited in a paper or cloth bag housed in a canister. The bag traps and retains the debris so that the canister itself stays clean. This type of system may or may not expel exhaust air outside. Every 1 to 2 years, the full bag is taken out and replaced with little or no exposure to the refuse. With paper/cloth bag systems, replacement bags must be purchased.

  1. Bagless with filter

With bagless central vacuum systems, dust is suctioned in and deposited in a canister. When the system is shut off, the heavier dust drops to the bottom of the canister and the lighter dust is trapped by a permanent filter. The filter prevents the dust from re-circulating back into the house or entering the motor. Exhaust air may or may not be directed outside through a vent. The canister needs to be emptied and cleaned every 3 to 6 months, at which time, excess dust also needs to be washed or shaken off of the filter. Cleaning and emptying the canister involves exposure to the refuse and so this system is not recommended for people with allergies and asthma.

  1. Bagless true cyclonic

With bagless true cyclonic systems, dust and waste are suctioned into the system with tornado-like force where the heavier debris falls down into a canister while the lighter debris goes through the motor and outside. Exhaust air is always vented outside with this type of system. The canister needs to be cleaned regularly―every 2 months― to maintain suction.


Consider a Central Vacuum System For The Good Of Your Health

Home automation offers people a great range of simple and convenient money and time saving benefits, as well as potential security benefits and along with this growing trend more and more folks are turning to central vacuum systems for the amazing benefits they can offer a home owner and their family.

Current research suggests that the air quality in your home is often worse than the quality of the air outside of it! Why is that? Because of the opportunities for mischief present in a home – trapped moisture, pet hairs, insects, output from electrical appliances, the materials used in cleaning products, dirt, mites, and many other things we don’t normally consider. This can be bad news for people who suffer from asthma or allergies.

A central vacuum system offers a real advantage to these families, because unlike ordinary vacuum systems a central vacuum system will not recycle dust and other potential allergy causing particles in the air of your home. The system works by filtering the air in your home through tubing placed behind the walls, and sucking in air through inlets in each room. This air is then expelled outside of your house and doesn’t allow those allergens to stay in the air inside.

Recent studies at the University of California have demonstrated that a central vacuum system can and will provide relief from discomfort and symptoms for asthma and allergy sufferers. What better reason could you have for investing in a central vacuum system? It’s a fully automated process so once you’ve had it installed you can forget about it and just enjoy the clean fresh air inside your home.
