What are some ways to increase ventilation in home during the COVID-19 pandemic?

• Open windows and screened doors. Do not open windows and doors if doing so poses a safety or health risk to children or other family members (e.g., risk of falling or triggering asthma symptoms).• Operate a whole-house fan, or an evaporative cooler, if your home has one.

What kind of filter should I use for my home air conditioning during the pandemic?

Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses. Many home HVAC systems will have a MERV-8 filter installed as the default.

How does fresh air work in HVAC systems?

The fresh air mixes with the semi-conditioned air already in the space, then is drawn into the HVAC equipment for conditioning and distributed to the home’s living space through the HVAC system’s supply ducts. This solution has proven to work quite well, and its initial cost as well as its power requirements are lower than for an ERV.

What is the difference between exhaust ventilation and supply ventilation?

Like exhaust ventilation systems, supply ventilation systems are relatively simple and inexpensive to install. A typical supply ventilation system has a fan and duct system that introduces fresh air into usually one, but preferably several, rooms that residents occupy most, such as bedrooms and the living room.

What is the difference between return air and exhaust air?

So return air is everything that is drawn through the return duct en route to the PDU. “Exhaust air”, also measured by volume in CFM or CMH, is the air that is discarded from the facility. In natatoriums, this is often through dedicated exhaust fan (s), and/or an exhaust fan located within the return duct itself. Let’s repeat that.

How do we bring that fresh air into the House?

We bring that fresh air into the house with two independently operating intakes located in the buffer space. A Fantech FR-125 inline fan with a 4-inch duct serves one intake vent, controlled by a Fantech switch in the laundry room on the main level.
