How do Air Purifiers Work?

Improve Your Home’s Air Quality For Better Health

Most people are aware that air quality can have a significant impact on personal health, but what many may not know is that the air inside a home is typically more harmful than air from outside. Every year, Americans spend millions on home air purifiers, but how these devices work and their beneficial impact can be difficult to determine. Some air purification systems can actually cause more harm than good.

Indoor Air Contaminants

The air inside a home carries far more contaminants than outdoor air. Indoor air collects moisture, pet hairs, and dander that can circulate through the home’s heating and cooling ducts, and outdoor allergens and other particles can blow in through open doors and windows, and get trapped inside. Smoking indoors directly spreads toxic smoke throughout the home.

Moisture is a major area of homeowner concern, as excessive moisture can encourage the growth of dangerous molds. Mold spores can be highly toxic if aspirated, so your home’s air quality and moisture levels definitely play a role in your overall health. Moisture, mold spores, tobacco smoke, allergens, pollen, and pet dander can be trapped in carpets, furniture, and linens, creating even more health hazards.

How Air Purifiers Function

Most home filtration systems clean the air circulating through the heating and cooling ducts. Filters are usually cotton, fiberglass, foam, or other synthetic fibers. The density of the filter’s fibers dictates how well the filter performs: Dense filters have very small gaps, meaning they can catch some of the smallest contaminant particles.

These filtration systems require diligent maintenance. While some filters can be cleaned and reused, most need to be replaced after a time. Filters also reduce the overall efficiency of the home’s heating and cooling systems, and they inhibit airflow even more if they aren’t replaced regularly.

Some people invest in standalone units that filter the air; you can move them from room to room, anywhere in the house. However, some of these are more harmful than helpful; air ionizers can circulate ions back into the air and stain furniture and other surfaces. Unless the air purifier is HEPA (high efficiency particulate air) certified, it isn’t worth the investment and may cause more problems than it solves.

Tips For Healthier Indoor Air

Before you commit to an air filtration system, there are a few things you may be able to change around your home to get the most return on your investment. First, clean your home thoroughly, especially areas that are dusty, rarely used, or collect moisture. Smoking should take place outside. Not only does this improve air quality inside the home, but smoking indoors is a fire hazard.

If you have pets, make hygiene a part of your routine to help eliminate pet dander and hair. Vacuum your carpets often and try to circulate fresh air through your home. Open a few windows to allow fresh outdoor air inside and blow out some of the stagnant indoor air. Once you’ve done these things, it’s time to consider an efficient air filtration system installed and serviced by professionals.
