Air Conditioner Filters and Allergies

People who suffer from allergies become more susceptible to allergens in air conditioned rooms. This is why the maintenance and replacement of air filters is important.

An air conditioning unit is the primary source of cool air particularly during the hot summer months. However, you have to make sure that this cooling appliance circulates clean air to prevent dangerous substances causing allergies from causing health problems like respiratory illnesses and skin allergies. Individuals who have allergic reactions are more susceptible to allergens that permeate the air in a covered room powered by an air-conditioning unit. This is why some homeowners choose to purchase air conditioning filters that can help fight off particles that can cause these allergic reactions.

Techniques in Containing Allergens

Filters are considered implements that keep in check indoor allergens. It can avert respiratory sicknesses and hay fever (allergic rhinitis) which are outdoor allergies but can be activated indoors. This happens specifically during pollination season when weedy plants and pollen grains are transmitted into homes through windows and other openings, such as air conditioner vents.  You can put in air cleaners together with the installation of appropriate filtering systems as control measure. When indoor air circulates through the HVAC system filters help catch and retai dust, mites, skin chips, pet fur, spores, pollen grains and other allergens. The installation of air cleaners with HEPA filters in baby nurseries and bedrooms can trap bacteria in these rooms.

High-tech mechanisms that eradicate these substances causing allergies are a big help for people who are hounded by allergies.  You can purchase air conditioning units fitted with state-of-the-art filters. These units have Minimum Efficiency Reporting Value rating system which determines the filter’s capacity to trap particles. The recommended MERV score for cooling systems in the home is either 11 or 12.  Incidentally, this so-called reporting value measures the performance of big air purifiers which are meant to clean a whole house or edifice. On the other hand, the smaller purifiers are rated through the Clean Air Delivery Ratings or CADR.

These filters are normally prescribed ratings from 1 to 16 although the upper limit can be extended until 20. The common residential air filtering systems tend to fall within a limited range. The higher marks imply more successful air filtration.

Importance of Ventilation and De-humidification

Remember that insufficient ventilation can increase the intensity of indoor allergens. HVAC units have not been manufactured to pull fresh air into your home. On the contrary, these circulate dormant air. By increasing the volume of fresh air entering the house, you can reduce the concentration of allergens and air contaminants.

Dehumidification is also important. This is one method of preventing molds from growing inside your domicile. Molds are usually found in rooms where there is lots of humidity like the kitchen, basement, or bathroom. These molds grow and release spores that are detrimental to human beings who are afflicted with allergies. Extreme dampness in the home brings about prime conditions for development of fungus. In fact, it is recommended that the humidity level inside homes should not go over 50 percent. Fix all water leaks to stop molds from growing in different parts of the house.
