Coronavirus Vs. Ventilation System In My House, Questions And Answers

For years, Ventilation system has been characterized by highlighting the importance of indoor air quality, which begins with good filtration and maintaining pure indoor air free of dust, pollen, bacteria and all types of contaminants in general.

In this way, our organism, living day by day in an indoor environment free of contaminants in our own home, will be able to count on an adequate well-being and excellent health conditions to face in optimal conditions any condition that might arise.

But these days, a multitude of confusing and sometimes contradictory messages reach our homes. Our technical and commercial team also receives queries about Coronavirus in relation to ventilation systems.

For this reason, we have compiled your most frequently asked questions, which are answered below.

Should I Turn Off My Ventilation Equipment Because Of The Coronavirus?

Absolutely not. On the contrary, it is recommended to ventilate as much as possible. By ventilating, we are cleaning the environment by removing the stale indoor air and replacing it with fresh outdoor air. Thus, more ventilation means more stale air removed, and there is a broad consensus that adequate ventilation reduces the transmission of infectious diseases.

Is The Coronavirus Able To Enter The House From The Outside Through The Ventilation System?

Experts from public health institutions in the European Union confirm that, in addition to transmission by contact, infection can only occur through the inhalation of droplets from the cough or sneeze of an infected person without being able to travel more than 5ft from the source of emission. Within that 5ft radius, the droplets can fall to the ground or even evaporate their liquid. In the case of the remaining nuclei of the evaporation, they are not considered to be a route capable of producing the transmission of the disease.

In Case I Have Installed A Heat Recovery System, Do I Need To Change My Filter More Often Now?

No. As mentioned in the previous question, the remaining nuclei of evaporation are not considered a direct route of transmission of the disease. Therefore, active viruses will not reach the filter of our ventilation system.

In Case Of Having Installed A Heat Recovery System, Can The Virus Colonize The Filter?

In any case, the virus in the form of a drop with a high viral load will not reach the filter because it cannot spread over long distances in the air. Since a virus is unable to replicate outside its host and therefore even in this unlikely case that a drop with active virus would reach the filter, it would remain there without any possibility of replicating until its biological death.

Is The Inclusion Of A Filter Barrier In A Heat Recovery Equipment (Residential Ventilation Unit) An Aid To Avoid Coronavirus, Or A Worsening Of Healthiness?

In practice, the virus in the form of an active drop (with a high viral load) will not reach the filter because it cannot follow a path of more than 5 ft through the air from the source of the virus. And in any case, as has already been mentioned, if it does reach it, it will be another barrier that will make it difficult for any element to enter the home, as if a mask were treated with a capacity for retaining particles in suspension from the air, depending on the type of filter.

Having a Mechanical Ventilation System (Is It A Factor That Increases The Risk Of Contracting Coronavirus?)

As already mentioned, health experts from the European Union assure that, besides transmission by direct contact, there cannot be an airborne contagion through cough drops or sneezes beyond 5 ft from the source of emission. Beyond a radius of 5 ft the nuclei resulting from the evaporation of the emitted droplets are not recognized as a route of transmission. On the contrary, it is recommended to ventilate as much as possible. By ventilating, we are cleaning the environment by removing the stale indoor air and replacing it with fresh outdoor air. Thus, more ventilation means more stale air removed, and there is a broad consensus that adequate ventilation reduces the transmission of infectious diseases.

Plumber arrived promptly to fix a blocked kitchen drain but immediately noted the flawed installation of the piping in our(relatively new) kitchen. I asked for a quote to fix the configuration of the pipes, which he did on the spot, then went and acquired the materials and had them all installed in quick time. An absolute gentleman as well. Cheers!

Alex carried out a clear and precise appraisal of the job of putting a new plumbing system into our house and removing the old one. He was up front about the cost carrying out the quote on the spot and describing what the job would entail labour wise. A good professional job done.

I had a problem with a drip from the pipe into the toilet cistern. I wanted it dealt with within 24 hours. The guy on the phone gave me a slot for 8am the next morning. Chris arrived exactly on time. He fixed it within the hour, and no problem with it since. In my book, worth paying for to get the certainty that they’ll turn up on time, to allow me to plan my work around the appointment.
