5. No matter how powerful the air purifiers are, it is compulsory to maintain them according to the instructions of the manufacturers. In general, carbon filters should be changed after three to six months, while a true HEPA filter can be used for almost one year while maintaining the optimal performance of the air purifier.
6. As for the heating system, the best one for allergic types is electric since it has no furnace that gives off pollutants. Unfortunately, most people use a forced air system with a furnace. So it is highly recommended that you employ an excellent furnace filter which is skillful at removing dust, smoke and other contaminants. You also have to replace the furnace filter every three months or less.
7. It is likely that mold and dust will accumulate in ducts. Therefore, it is also essential to clean the ducts. You may hire a duct-cleaning service, but remember to hire one that doesn’t use irritating chemicals.
8. Decorate the walls in your house with low allergen, low volatile organic compounds (VOC) paint rather than wallpaper, for the latter is much more easily contaminated than the former.
9. Also, use low VOC hard surface flooring instead of carpeting the floor because carpets hold pollutants such as dust, smoke and pollen. If you prefer carpeting, you should not be surprised to find you have to do heavy cleaning every day.
10. Give priority to dryness in your house and prevent a damp environment since this might result in mold and even spores. In fact, molds are usually produced in humid areas, for example, the bathroom or the washroom. As a result, it is crucial for you to control the moisture in constantly damp spaces. A dehumidifier is very helpful. Keep the humidity level between 40% and 60% with the help of a hygrometer.
