The concept of filtering air on the way out was raised, but it’s unlikely that the fan would be able to generate the necessary negative pressure with the added resistance of a HEPA filter in this case. While it is unlikely to be a major problem once dispersed by the wind, it would be poor form to be exhausting COVID+ air into a crowded area. But in an urban environment, be sure the designated room does not exhaust directly on to a sidewalk or common area. Where is your fan exhausting toward? In a suburb or a rural area, this is probably a non-issue. Exhaust any contaminated air in a safe direction Another important room selection consideration is to not exhaust the contaminated air into a populated area. If strong enough, this could even result in a reversal of the fan and temporarily create a positive pressure room. Another consideration is if there is a prevailing wind, to consider a room that is downwind so that the exhaust fan is not working against it. Second, it provides access to a bathroom without the sick person needing to pass through the rest of the living space. Contamination into other spaces (may) be somewhat mitigated with a HEPA filter between the patient and the door in both cases. If the door to the negative pressure room is opened without an airlock of sorts, then there will be a loss of negative pressure and contamination into the other spaces. The ideal setup for a home negative pressure room would include a “Jack and Jill” bathroom or “ante room” before reaching the bedroom. Immediately, others in the household are drastically less likely to be exposed to COVID-19. So you’ve created your negative pressure room. That’s it! You’ve created a negative pressure room. Place the fan in the window of the designated room (like a bedroom) blowing outward and seal the edges. The simplest solution is a window-mounted exhaust widely available for around $24.99.

Although this setup is conceivable in a home environment, it means you have to have Central Air in the first place and would involve some additional HVAC work including a full upgrade of your system to accommodate industrial filters (more on that later). A Home Negative Pressure Room for $24.99Ī hospital-based negative pressure room may exhaust the air back into the industrial HVAC system with industrial-grade HEPA filters before recirculating around the rest of the hospital. But what about taking care of a patient at home? Although this sounds cost-prohibitive, this can be accomplished for as little as $24.99 with a simple window fan. This is what is used, when available in hospitals throughout the world in order to aid in preventing the spread of COVID19 and other airborne pathogens. Essentially, the air is “sucked” into the negative pressure room like a vacuum cleaner while none of the air from the negative pressure room enters the rest of the building. In essence, it’s a room where the air is continually exhausted out of the room so that no contaminated air from that room enters any other rooms. What happens when you, your housemate, or your child develops flu or COVID-like symptoms? How do you keep others, especially those at high-risk safe while caring for the ill patient? What is a Negative Pressure Room? We may not want to face it yet, but between Seasonal influenza, limited opportunities for outdoor socialization, and the ongoing question of school re-openings, the COVID-19 Pandemic is about to be amplified in a major way. In order to reduce health disparities, these solutions must be within reach to as many people as possible. At Thrive Direct Care, I believe that my Hippocratic Oath “first do no harm” includes “first do no financial harm”, and the consideration of cost is critical. There exists a multitude of reasons for healthcare disparities in these communities but one of them may be denser living conditions and a higher rate of exposure through essential jobs. This is especially critical to those living with at-risk family members or in dense-living conditions. COVID-19 has disproportionally hit communities of color.

In this post, I’ll detail how to create a home negative pressure room just like we use in the hospital to reduce the spread of COVID19 for under $25.
