9) Change Your AC Filter

AC filters generally need to be changed every 30-45 days, depending on your allergies. If you don't change your AC filter, outdoor air pollutants will enter your house. Dust, pollen, hair, and pet dander can clog the installed air conditioning in your living room and restrict airflow. Not to mention, you will receive higher utility bills.

Outdoor air pollution, like harmful chemicals and other airborne particles, will make its way into your house and can pose a health risk. Clogged AC filters in indoor spaces will cycle back volatile organic compounds into your house, then keep short cycling. The whole process is messy and not recommended.

10) Buy a Good Air Filter

Buying a portable air cleaner can be cost-effective in the long run, clean indoor air, and improve your health. Have you ever woken up with blocked sinuses and allergies? Those are tell-tale signs of poor indoor air quality. Therefore, an air filter is more dependable than a blocked AC filter.

Air filters do a great job of removing smaller particles and other health hazards from your space. They are also very handy for source control. Therefore, if you have a pet, any dander is immediately removed. Additionally, if you sometimes use natural ventilation, it is best to adjust the ventilation settings on your air filter to high immediately after, so the air filter can do its job.

Furthermore, a good alternative to normal air filters is Corsi-Rosenthal boxes. They are made like box fans, with a few filters glued together. They still work well to keep your space free of indoor air pollutants and come minus the hefty energy costs of a stalling air purifier. Not to mention you can construct one yourself.
