Your home may feel like the safest place in the world, but it could be hazardous to your health. Pollen, dander, mold, smoke and dust mites circle through the air in most houses, causing an invisible smog worse than outdoor pollution in a major city. A whole house air filter is the most effective way to combat that air pollution and keep breathing problems at bay, but it's important to understand the costs associated with installation before making a decision.

Types Of Air Purifier Systems

Why Install An Air Filtration System

There are many reasons to consider installing an air filtration system, but your health is number one. Invisible pollutants located in most homes can lead to many problems, including the following:

  • Allergies
  • Asthma
  • Respiratory Illnesses
  • Dry Eyes
  • Headaches
  • Nausea
  • Fatigue
  • Nasal Congestion

Even if you dust, vacuum and clean your house daily, it probably still hosts a number of air pollutants that you can't see with the naked eye. That's where the whole house air cleaner comes in. Homeowners who install them see a reduction in allergies and other respiratory health issues. Other benefits may include:

  • Reduction in secondhand smoke impact
  • Fewer illnesses due to the reduction of germs circulating through the house
  • Reduction in odors
  • Fresher, cleaner air

Types Of Air Pollutants

Types Of Air Purifier Systems

There are four main types of air purifying systems: flat, extended media, electronic and ultraviolet. Each one offers unique characteristics.

  1. Flat Filters: At around $15, these are the least expensive, but they require monthly changing and don't always work as well as others. They can attract dust, clog easily and fail to trap microscopic particles. They can also overwork your furnace if they become too clogged with dust and dander.
  2. Extended Media Filters: These filters require professional installation and must be changed annually. The typical filter costs between $40 and $60 before installation fees. Unlike the flat filter, these can trap the smallest particles.
  3. Electronic Filters: If someone in your home smokes, an electronic filter is ideal. It traps particles, including some secondhand smoke, like a magnet. They can cost $600 to $1,000, but never need changing. The only requirement is a 120-volt electrical outlet, and you must wash the aluminum collector plates every few months.
  4. Ultraviolet Filters: Hospitals usually install ultraviolet filters because they're excellent at zapping up germs, viruses and bacteria. Considered an add-on to your whole house electronic precipitator, the price is typically between $400 and $800.

Types Of Air Pollutants

Many people assume that visible dust is the only pollutant in the average home, but there's much more floating through the air than meets the eye. Each home is different, depending on who lives there and how it's set up. Take a look at some of the most common types of air pollutants.

  • Pollen: Pollen is typically carried inside on shoes and clothing and can float in through open windows and doors.
  • Cleaning Products: Some commercial cleaning products contain compounds that infiltrate the air and irritate the respiratory system.
  • Radon: Radon is a naturally occurring gas that's one of the leading causes of cancer in the U.S. If you have a basement, you're more likely to have it in your home.
  • Mold: Leaky roofs, damp basements, attics and bathrooms without proper ventilation can all lead to mold, which can cause serious breathing issues.
  • Building Materials: Some building materials, especially in older homes, release emissions that can negatively affect air quality.
  • Secondhand Smoke: If someone in your home smokes, secondhand smoke adds dangerous toxins to the air.
  • Pet Dander: If you have a pet, its hair and dander sticks to carpets and furniture and pollutes the air.

Do You Need An Air Cleaner

Do You Need An Air Cleaner?

According to the Environmental Protection Agency, almost any home can benefit from an air cleaner. The agency estimates that most people spend 90% of their time inside their homes, which means you spend most of your life exposed to these pollutants. Older homes are specifically at risk, but newer homes can benefit from air cleaners, too. This is especially true if you have children, senior citizens or a person of any age with allergies or preexisting medical conditions living with you. 

The best way to find out what's floating around your home is to perform an indoor air quality test. The average cost is around $405, with most homeowners spending between $328 and $443. You can get a DIY kit at your local home improvement store, though these kits don't always test for all pollutants. Hiring a professional can help you determine exactly what's in your home.

How To Prevent Air Pollution

Once you determine you have an air quality problem, there are steps you can take to eliminate pollutants:

  1. Stop smoking.
  2. Vacuum, dust and clean your home regularly.
  3. Consider adding plants that help purify the air.
  4. Hire a professional to eliminate dangerous pollutants like radon and asbestos.
  5. Invest in a dehumidifier to keep indoor humidity levels at 30 to 60%.
  6. Clean your air ducts and vents regularly. The average cost to do this is $327, with most homeowners spending between $278 and $364. This will also increase the life of your HVAC system.

How To Prevent Air Pollution

DIY Or Hire A Pro?

While it might be tempting to save money and install your own whole house air cleaner, hiring a pro may be less expensive in the long run. The filter is built into your return-air ductwork, and turning it into a DIY project may lead to more problems with your entire HVAC system if you don't install it correctly.
