Check and change air filters regularly
Checking your system’s air filters on a regular basis will help to greatly increase your home’s indoor air quality. You should clean or replace air filters about once a month, depending on whether you have replaceable or disposable filters.
Maintain your air purifier
If you have installed a central air purification system in your home, it is a good idea to thoroughly clean it two or three times a year. Cleaning out dust and debris from pre-filter and collection cells at the start of every heating and cooling season will help maintain peak performance.
Keeping ducts clean
While cleaning your home’s entire duct system yourself is not recommended, you can still clean key areas. Removing the vents at the registers in your home will allow you to vacuum areas that receive plenty of dust buildup. Make sure your vacuum's attachments are tightly connected to ensure that none become dislodged inside of your ducts.
Protect from moisture build-up
Utilize bathroom and kitchen ventilation fans to help remove excess moisture from these areas of your home. Whenever a room is in use, turn on the fan. If rooms do not have fans, consider installing one as they help to greatly reduce moisture build-up and the lessen potential for mildew growth.
Keep your air clean
Regular vacuuming and dusting can greatly help to improve indoor air quality. Washing bed sheets and drapes can also help reduce allergens and irritants, giving you and your ventilation system a break.
Changing an air filter
Locate the portion of your ventilation that contains your air filter. If you do not know where that is located, simply ask the next time you have a professional service your system, or simply call your service company. Most systems have a hatch or access panel that will open to expose your main filtering mechanisms. Locate your filter and simply slide it out. After you have removed the filter, be sure to clean out any dust or debris that may be located in the surrounding area. It will quickly re-clog your system if it is not removed. Depending on the type of filter you have installed, either clean or dispose of the filter. Slide the new or cleaned filter back into the slot and close the hatch or access panel.
