Indoor Air Quality

Is your Home Healthy?

Indoor air quality can affect everyone in your family

Pollen. Mold. Dust.

Particulates in the air, like pollen, mold and dust, can result in health problems like allergies and asthma. They also affect the indoor air quality of your home.

It is no secret the EPA estimates that indoor air quality is often far worse than outdoor air quality. In fact, they estimate that indoor air pollution is one of the top 5 environmental health risks!

What can you do to protect your family?

Ventilation and control or elimination of pollution sources are the best defense. A good HVAC system is a great start. Basic equipment maintenance, like replacing filters regularly, goes a long way. Air cleaning devices to augment your HVAC system can also help. Here are a few to consider.

Filter changes and HVAC system maintenance

HVAC filters

The simplest thing to do is keep your air filters clean! Check and replace them regularly. Dirty filters can cause your HVAC system to work harder pushing air through, using more energy, and resulting in higher utility bills. Check them monthly.

Air filters work to trap particles like dust and pollen. They come in various sizes, and rated on a standard set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). You can evaluate the filter efficiency of removing airborne particles from the air stream that passes through it by checking the MERV rating. This rating allows you to compare brands and types of filters.

We recommend a MERV rating of 7-13, which work nearly as effectively as higher ratings. We do not recommend using HEPA filters (MERV ratings 14-16), as they block airflow and cause your equipment to work harder. This means equipment will likely wear out faster.

A good filter:

  • Traps dust particles
  • Traps some pollens and mold
  • Helps keep your ducts clean and running efficiently – and keeps utility bills lower

HVAC equipment maintenance

HVAC systems should be checked and serviced twice a year for preventative maintenance. Although, as with any machine, they can break down in between, preventative maintenance can keep failures to a minimum, and catch the need for replacement parts before they fail. Think of it as an oil change for your car!

At John Waters, we offer three types of service level agreements to save you time and money.

Duct Cleaning

While John Waters does not provide duct-cleaning services, most reliable carpet cleaning professionals can clear your duct system. You may want to consider this if:

  • You live in an older home
  • Renovations have been done. Work on dry wall, cabinets, flooring cause large amounts of dust
  • You have pets
  • Windows are open regularly (especially high pollen times)
  • Smoker(s) live in the home
Ultra-violet lights benefits your home

Ultra-violet light: kill mold, germs and odors

Ultra-violet light air purifiers, also known as “blue light” systems, install in the ductwork of the central air system. They work by “scrubbing” the air with UV light as it passes by. The UV light kills molds, viruses, bacteria and more as the air works through the duct system of your home.

At John Waters, we recommend the award-winning APCO in-duct air purifier. This air purifier combines UV light and activated carbon to reduce germs and odors without producing harmful ozone. The APCO system reduces odor-causing volatile organic compounds (VOCs) like formaldehyde and toluene vapor.

This product comes with a manufacturer’s lifetime warranty on all parts (no labor) except the UV lamp, which needs to be replaced every one-two years, depending on the model.

Global Plasma Solution: electrical charges to reduce contaminants

An alternative to the ultra-violet light air cleaner is an electronic version. This system (GPS) uses an electrical charge to reduce air contaminants. GPS’ independent testing shows cold plasma kills 99.6% of contaminants in the space in less than 15 minutes! Plasma kills a variety of bacteria and viruses including:

  • H1N1 Feline
  • Coronavirus
  • HSN1 Coxsackie virus
  • MRSA
  • Polio Virus
  • SARS virus
  • e.Coli
  • Serratia Bacterium
  • (TB)
