What Causes Poor Air Quality?

Indoor air pollution can be caused by a variety of factors. Some of the most common include emissions from cigarettes, cleaning products, fireplaces, and various chemicals stored in your home. Air pollution from dust or other allergens can be especially harmful to people who have allergies or a compromised respiratory system.

Home renovations can also be a significant culprit when it comes to decreasing the air quality in your home. When weatherizing a house to save on energy bills, you may be putting yourself at risk for indoor air pollution. Adding more insulation or caulking to your home can reduce air circulation, making it difficult to get fresh air into your house.

Air Scrubbers

Air scrubbers are the best option for homeowners looking for a heavy-duty air cleaner. Contractors and construction workers use these during home renovations to clean the air from dust, debris, and other harmful air pollutants. Air scrubbers are terrific options for allergies or working with mold inside a home.

Air scrubbers create an airflow to suck in the polluted air, then vent out clean air. It attaches directly to your HVAC system’s ductwork. A pre-filter first captures the large particles, and a HEPA filter captures nearly all the tiny particles. The pressure created by the air prevents cross-contamination of polluted and clean air.

Whole-home air scrubbers are designed for continuous use—cleaning your air every time your system runs.

Thankfully, our skilled technicians are trained in installing the air scrubber plus, a portable air scrubber, discreetly into your home’s duct system. It weighs only three pounds and can filter homes up to 5,000 square feet in size using UV light technology. The best part? We also offer same-day installation!

Air Filters

If an air scrubber isn’t what you’re looking for, an air filter is your next best bet. Like air scrubbers, air filters purify the air around them by removing airborne particles and pollutants. Air filters are commonly found in homes, offices, hospitals, and other commercial spaces.

An air filter draws in unclean air through multiple filters to strain harmful particles. The primary filter needs to be replaced as it gathers more dust and air pollution. We utilize the Purair Air Purification System by Lennox when installing air filters into homes. This heavy-duty air filtration system uses a Carbon Clean 16 filter to trap pollen, dust, cold/flu viruses, and odors before they enter your home.

The Purair Air Purification System also includes built-in sensors that monitor the life of the UVA light and filter. It does not release ozone into the air. In fact, this system eliminates ozone as well!

If you’re not sure which air purification option to go with, talk to one of our professionals for expert advice. We will conduct a free assessment of your home to decide which option is best for you.

And if you’re considering solutions, many homeowners ask whether whole-home air purifiers actually work—the answer depends on your system and setup.

Duct Cleaning

Sometimes the best course of action is to allow the professionals to handle the job. If you’ve tried air scrubbers and air filters but still have poor air quality, it may be time for a duct cleaning. Having your air ducts cleaned means that everything within your duct system is cleaned using professional air duct cleaning equipment. 

Your ducts can become so clogged with dust or debris that those particles make it through the vents and into your home. Duct cleaning is also necessary if you notice mold growing in your air ducts or other parts of your HVAC system. Having your air ducts cleaned is perfect preventative maintenance for mold issues.

We offer air duct cleaning services to help keep the air quality in your home pristine!

If you’ve been wondering why your home feels so dusty, it could be a sign your system isn’t filtering air properly.

Common Indoor Air Quality Problems in Bellingham Homes

Air Quality Testimonials

Rated 5 out of 5
I have had many dealings with contractors over the past 50 years. Clean Air Comfort Systems recently installed a mini split system heat pump to replace our electric baseboard heat system. While it is to early to determine the operating efficiency, I am pleased to report this as the first 5 star experience I've ever enjoyed.

Always good service from technicians to their customer service. My technician today for my yearly service was Easton. He was personable, knowledgeable and familiar with my units. He spend extra time problem solving an issue I had and advising me of solutions. All the technicians that have provided service over the years have been great. I recommend Clean Air to anyone for quality service!
