A home ventilation system brings in fresh air from outside and drives away the polluted, stale air from inside, thereby ensuring a healthy living condition for the inmates of the house. It also helps to keep the humidity levels under check, that is, within the moderate 30-50%.
The air inside your house is often over-used, because fresh air gets in only when you open doors or windows. Since today’s homes are made more energy efficient, indoor air quality deteriorates and homes get suffocated soon. And because natural air-flow is restricted, these homes have to struggle hard to breathe.
Today’s common tendency to conserve energy directly affects the indoor pollution levels in a home. Without enough home ventilation, the pollutants keep growing and start gaining denser concentration. There are many origins to these pollutants and some of these like molds give more trouble if the humidity levels are high in the house. So this is another problem which might arise from insufficient ventilation in the home.
In a home where the humidity levels are pretty high, the mold, mildew and rot can spell total disaster. If mold spreads all over the house, the consequent damage control can burn a hole in your pocket and in extreme cases, might make the entire house unlivable as well.
Dust mites are yet another problem with having high humidity levels in a house. These are quite regular in households, but they flourish more in a humid environment. So you might take this under serious consideration if you or anyone in your home suffers from dust mite allergies.
Low humidity levels are no consolation either. They often result in nasal irritation, throat problems and dry skins. Moreover, woods shrink and crack in low humidity. So this can even take its toll on your hardwood flooring—they can make creaky noises when you walk on. The most obvious symptom of low humidity is static electricity.
To give your dear ones a healthy living condition, you can start with a proper home ventilation system precisely because it’s highly essential and is not hard to achieve.
The most significant parts of a home ventilation system are—air exchangers, ventilators for heat recovery, exhaust fans in the bathroom and kitchen, dryer vents, ventilation fans for the attic, and vents for the crawl space and attic.
In the absence of proper home ventilation, these are some of the pollutants that can creep in and grow in your house—mold spores, dust mites, pollen, lead, pesticides, pet dander, tobacco smoke, household chemicals, paints, solvents, cleaning supplies etc.
Without sufficient home ventilation, you may also face problems with the carbon monoxide, carbon dioxide and soot given out from gadgets and heating systems that run on fuel.
There are some very important health benefits to home ventilation too. Allergy and asthma symptoms are greatly checked along with other respiratory problems and diseases that are widespread among people nowadays.
