Benefits Of Getting An Air Purifier

When choosing an air filter, they offer several benefits. Air filters with HEPA filters can remove 99.7% of particles and pollutants in your home environment.

Other benefits include:

  • Improved health and rest: Sleep better, avoid sharing cold and flu germs, and reduce asthma symptoms by capturing dust mites, fungi, bacteria, dander, and pollen. These cause breathing difficulties, hay fever, coughing, sneezing, and watery eyes.
  • Remove harmful chemicals: Vehicle gasses (carbon monoxide, nitrogen dioxide) can raise Alzheimer’s disease and dementia risks. Household cleaners have toxic chemicals (chlorine, ammonia, and phthalates). These can increase tumor, cancer, and cardiovascular and neurological disorder risks.
  • Neutralize odors: Volatile organic compounds (VOCs) in some aerosol sprays can include benzene, gas, and formaldehyde, which can cause breathing problems, nausea, and cognitive problems.
  • Remove Radon: Some building materials, soil, rocks, and granite produce radon gas, but HEPA filters block the particles.
  • Eliminate harmful asbestos: Found in insulation pipes and roof materials, dust can cause lung disease and increase cancer risks. However, HEPA filters are excellent for capturing these types of particles.

Air Purifier Installation

Air purifiers can lower pollution levels in your indoor air and improve your overall air quality. With filters lasting for two to three months, let us test your indoor air quality and find the right filter for a better indoor environment. Air purifiers suck in air, trap pollutants (dust, bacteria, pollen), and release clean air into your home.

Examples include: 

  • HEPA-filtered (capture pollutants 0.3 microns)
  • Ultraviolet rays (UVs kill germs and have washable filters)
  • Electrostatic precipitators (use volts to kill pathogens on a plate)
  • Ozone generators (absorb odors)
  • Activated carbon (traps odors, viruses, and bacteria)

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
