How to Keep Elders Healthy Under Family Care or Aging in Place
Deciding how and where to best care for senior citizens as they get older can be an emotionally fraught experience. There are also several practical considerations that go into the decision to ensure their needs are met. Whether families decide to move their elderly parents in with them or to keep seniors in their own homes, a top priority is facilitating both a safe and healthy environment.
What Residential HVAC Systems Were Designed to Do
Residential HVAC systems are designed to ventilate and filter air to maintain adequate air quality and control temperature. Ventilation and filtration remove odors and trap dust, smoke, and pollen. However, residential HVAC systems are not designed to capture toxic microorganisms.
HEPA filters capture pathogens which include bacteria, viruses, and even mold spores. Unlike hospital-grade HVAC systems, most residential units do not generate powerful enough airflow to overcome resistance caused by HEPA filters. Therefore, adding one to a home HVAC system is not a viable means of containing contaminants.
One way to reap the benefits of HEPA filtration in homes is through air purifiers equipped with HEPA filters. Since they reduce the number of particles that carry viruses by approximately 95%, they are considered medical grade.
Humidity Control Matters, Too
According to the International Journal of Environmental Research and Public Health relative humidity (RH) levels between 40-60% are optimal in homes for two reasons. First, mucous membranes are most resistant to infection around moderate humidity levels. Second, viruses living in aerosol particles survive for less time at 50% RH than in drier or very humid conditions.
Humidity control is not standard in residential HVAC systems, but it can be added retroactively. However, humidity control functionality that is incorporated into furnaces or central air conditioning only works when the system is running. Similarly, controlling humidity levels is not available through forced-water heating that uses boilers. If moisture control is not available through a household HVAC system, a stand-alone humidifier that monitors room levels will get the job done.
Volatile Organic Compounds
Exposure to volatile organic compounds (VOCs) can have short- and long-term adverse health implications. VOCs are gases emitted from various household products including new carpets, aerosol sprays, paint, PVC plastics, and air fresheners. VOCs originate indoors, and exposure to moderate levels of VOCs over time or high levels of VOCs in a short period of time can cause minor eye, nose, and throat irritation. Over time, higher concentrations of VOCs can cause liver, kidney, and central nervous system damage.
Air Purifiers have their Limits
According to Consumer Reports, air purifiers can remove contaminants only when they are floating in the air. Mites, mold, pollen, and VOCs are too heavy for most air purifiers. Units with HEPA filtration can capture aerosol droplets on which the coronavirus travels, but not all purifiers draw in enough air to actually reduce the volume of particles.
The Bottom Line
Avoiding harmful contaminants and facilitating quality indoor air is achievable, even in a private setting. Fortunately, a highly effective solution can be as simple and unobtrusive as a window AC unit.
Air Innovations brought over 25 years of experience designing and manufacturing customized solutions for temperature, humidity, and filtration control to its HEPAiRx window-mount ventilating air purifier. The HEPAiRx system is a plug-and-play air filtration device comparable in size to a standard AC unit. The system quickly and thoroughly purifies a room of airborne particles and contaminants because each unit features medical-grade HEPA filtration and ventilation to exhaust air for a standard-sized room every 30 minutes.
The HEPAiRx unit brings in a high enough quantity of fresh air to naturally dilute VOCs without requiring a window to be open. It also uses upstream UV-C to kill viruses trapped on the intake side of the HEPA filter to give seniors an extra buffer against life-threatening elements. Lastly, the system has onboard heating, cooling, and humidity control features to keep residents comfortable.
The HEPAiRx system is currently the only solution on the market that can do the following:
- Brings dedicated fresh air into a room to naturally dilute potentially harmful aerosol particles, VOCs, and gases.
- Uses optional upstream UV-C to kill viruses trapped on the intake side of the HEPA filter – the only effective way to kill viruses on the HEPA filter.
- Integrates the HVAC to isolate the space from the existing systems. HVAC ductwork is a source of cross-contamination between spaces. The HEPAiRx system seals off the current system to separate it from adjacent rooms creating an actual isolation space.
Air Innovations’ HEPAirX system empowers adult children to take a proactive approach to keep beloved older family members safe and healthy. Or, the unit enables senior citizens to take charge of their own contamination control.
