The filters of such units may act as a nidus for the growth of fungi. In this survey, filters of AC units in 25 operating theatres in India were evaluated quarterly over two years. The overall rate of fungal colonization of the AC filters was 26%. In addition, window-mounted AC units had higher fungal counts than wall-mounted AC units. We conclude that although the exact load of fungal spores necessary to initiate infections is unknown, AC units in operating theatres should be meticulously maintained and frequently monitored to minimize the chances of growth and proliferation of potentially pathogenic fungi.

Data from this study also suggest that the design of the AC unit may play an important role in reducing fungal spore counts in the air of operating theatres in developing countries.PMID: 15823663 DOI: 10.1016/j.jhin.2004.10.011 [PubMed - indexed for MEDLINE] Publication TypesEvaluation StudiesMeSH TermsAir Conditioning/instrumentation*Air Microbiology*Air Pollution, Indoor/analysis*ClimateColony Count, MicrobialDeveloping CountriesDisinfectionEnvironmental Monitoring/methodsEpidemiological MonitoringEquipment Contamination/prevention & controlEquipment Contamination/statistics & numerical data*Equipment DesignFiltration/instrumentationHealth Services Needs and DemandHumansIndia/epidemiologyInfection Control/methodsMaintenanceMycoses/epidemiologyMycoses/etiologyMycoses/prevention & controlOperating Rooms*Population SurveillancePostoperative Complications/epidemiologyPostoperative Complications/etiologyPostoperative Complications/prevention & controlPrevalenceSeasonsSpores, Fungal*Full Text SourcesElsevier quiet central ac units reviews

ScienceMedicalIndoor Air Pollution - MedlinePlus Health InformationWe can't afford an office under a tree, but 9 hours in an AC workplace means you are at risk They weren't lying when they said you can survive on love and fresh air. Being in open spaces, research has proved, strengthens your immunity since white blood cells that fight bacteria need oxygen to function effectively. air handling unit problemsA free supply of oxygen means your blood pressure and heart rate is in check since the body isn't overworking itself to acquire it. window ac unit in a vanBlood oxygen levels are also linked to serotonin, the 'happiness hormone', which is why you are more likely to slip into a refreshed, relaxed state when in green outdoors. The hitch, of course, is that most urban residents end up spending close to nine hours a day in air-conditioned offices, often following it up with a whole night's sleep in closed, cool bedrooms.

Your lungs are the first hit, which is why respiratory infections including common cold, frequent headaches, itchy throat and symptoms of flu, are most common among young, urban professionals. Fresh air that helps the lung's airways to dilate, releasing airborne toxins from your system, is scant in swanky AC offices. Dr Gauri Mankekar, consultant ENT surgeon at Hinduja Hospital, says an air conditioner is able to cause cooling through the process of evaporation. "Thanks to the very manner in which it functions, an AC ends up drying the mucous membranes in the nose and mouth," she says. Our nasal passages, sinuses and throat depend on moisture in the membranes for their immune functions. When moist, the immunity cells are able to attract and trap viruses, bacteria and allergens, acting as the body's first line of defence against airborne pathogens. Most air-conditioners aren't fitted with humidifiers, upping levels of dryness in the surrounding air. This constant and direct exposure to cold, dry air can ruin the skin, robbing it off its elasticity, leaving it itchy, scaly and aged.

Skin conditions like dermatitis and eczema are common among those who spend long hours in cool, dry recycled air, says dermatologist Dr Sushil Tahiliani. More harmful than the low temperatures is the growth of mold, a microscopic fungi, that lives inside AC vents and ducts, with high moisture levels and dust offering it a good breeding ground. While filters fitted in AC units are designed to prevent the spread of bacteria and virus, if not cleaned regularly, with the accumulation of pollutants over time, they end up hosting bacteria. "Since it's the same stale air that's re-circulated all day, we end up inhaling viruses and droplet infections," says Dr Mankekar. Ideally, filters should be cleaned once a month. When the AC serviceman arrives, make sure he uses anti-fungi chemical solutions instead of using a simple vacuum and brush that will only loosen the mold. The corrective plan - While working in a ventilated office isn't an option for most of us, try and reduce the number of time you sleep in a closed, AC room.

Open all windows, doors and let in sunlight every morning. Air out your linen in between washing cycles. - Make sure the office AC is set to 25 degrees. This 'average' temperature helps because it doesn't 'shock' a new entrant who might be walking in from the blistering heat outside. Sudden and extreme temperature fluctuations in the body can also affect the joints. - Dr Mankekar suggests you layer your body with sufficient clothing inside AC rooms, and un-peel when outdoors. - Install a warm mist humidifier at work, if possible. Else, keep a large vessel with a wide mouth filled with water in a corner of the office. It can work towards circulating moisture in the air. Keep yourself hydrated by drinking water every few hours, splashing your eyes with water and going out for a quick stroll during lunch hour to get a dose of sunlight and oxygen.For homeowners who plan to live in the house for several years, central air conditioning is a more popular option, particularly for a home that is equipped with a forced-air heating system.

Central air conditioning costs a lot more to install than a couple of room units—figure $3500 or more for central AC—but central AC cools the entire house, is more energy-efficient than running several portable units, is quieter than room air conditioners, is hidden from view, and is an investment that ads to the home’s value. For more about how a central system works, see How Central Air Conditioning Works. Before making a decision, also be sure to check out HomeTips’s information on Heat Pumps, which can be a more affordable means of cooling many homes than central air conditioners. So, when deciding between buying one or more room air conditioners or a central air conditioning system, ask yourself the following: 1Do you own your house? If not, you’re stuck with room air conditioners unless you can talk your landlord into installing central AC. 2Will one or two room AC units do the job? If so, this is probably your best answer because you can get AC working quickly and relatively inexpensively, and your energy bills will be lower than they would be if you were running central air conditioning.
