Does Indoor Air Filtration Protect Against COVID-19?

Indoor air filtration systems are a crucial part of the heating, ventilation, and air conditioning (HVAC) systems. With respect to COVID-19, indoor air filtration can be utilized to help you mitigate the risk of exposure, however, it’s not the overall solution.

Since the pandemic started, we have taken extra steps to research the correlation between an indoor air filtration system and COVID-19. We have since made several inferences that will be fully discussed in this section. Scientifically, there is no evidence that these systems can be 100% effective against the spread of the virus. However, inferences can be made to the fact that reduced exposure may be a possibility. This is because some indoor air filters remove large-sized droplets and particles.

However, if your indoor air filtration system is going to be useful during this period, it is important that it is maintained by experts. Your air filters have to be regularly treated to ensure that they recirculate air appropriately. More importantly, it is crucial that your indoor air filtration system is the right one for your building. Be sure to speak to HVAC experts in Toronto about your air filtration needs. Instead of DIY, hire an HVAC company that will be able to guarantee complete efficiency.

When discussing the effectiveness of indoor air filtration systems against COVID-19, it is important to note that they are not a substitute for other recommended measures. Social distancing, isolating known cases and hand washing are still the most effective ways to prevent the spread of COVID-19.


How Indoor Air Filtration is Useful for Residents in Toronto 

Most people assume that for an air filtration system to be useful, the disease you are preventing has to be airborne. Public health information has suggested that the Coronavirus is spread by large droplets. However, this is why we earlier mentioned that an indoor air filtration system is just a small part of the solution.

The difference in transmission by air or droplets is a function of particle size. This means that small droplets can easily become airborne and remain that way for a long time. Additionally, air droplets can change size as a result of relative humidity. The DNA from other viruses spread by droplets has been found on air filters. This shows that under the right conditions, a correctly installed indoor air filtration system can be a defence system. More importantly, it will definitely improve indoor air quality in your home contributing to positive health conditions.


What Indoor Air Filtration System Should I Use?

There is no direct answer to the question of the best indoor air filtration system to protect you from COVID-19. One major reason for this is that there are several unknown facts about the coronavirus. However, we do know that filtration systems with low-efficiency filters are unlikely to have any form of positive effect. Low-efficiency filters are those with a MERG rating of less than 8 according to ASHRAE Standard.

On the other hand, air filtration systems that are properly installed by experts may prove to be more useful. They are designed to capture small droplet sizes based on the efficiency of their capture process. However, current information on the nature of COVID-19 does not allow for recommendations on the best indoor air filtration system. In the end, it is important that you consult with the experts. Speak to HVAC and indoor air filtration experts in Toronto about your concerns.

Some people in Toronto are under the impression that high-efficiency filters may be more useful in counteracting COVID-19. However, this is not the case. Typically, a high-efficiency filter will accumulate dust faster. Additionally, it comes with a substantial drop in pressure in atmospheric conditions. As a result, there may be reduced air in your home especially if this filter is not right for your building specifications.

The same thing goes for filtration systems used by hospitals. Some residents in Toronto think that they may be efficient in keeping out COVID-19. However, these systems will not be very efficient in residential and commercial buildings. Most times, hospital filtration systems rely on elaborate mechanical systems. These systems are also used in conjunction with other filtration systems that will be discussed in the next section.

Basically, the protection of an indoor air filtration system offers against the virus is not fully effective. However, getting an indoor filtration system for your Toronto home may still go a long way to ensure the quality of hair in your home. Combining these systems with social distancing and handwashing recommendations will totally protect you during the COVID-19 pandemic. More importantly, it offers so many more benefits and will definitely prove useful long after the pandemic passes.

Protecting Indoor Air Quality: Other Systems You Can Use

The right indoor filtration system can be bolstered to help prevent COVID-19 when used with other systems. HVAC experts can use ultraviolet lamps as well as portable cleaners to boost the quality of air in your environment.

Ultraviolet (UV) Lamps

A well-installed maintained and installed UV system can be combined with filtration, airflow management and humidity control to reduce the risk of infection from certain viruses. However, it is important that this system is installed by professionals. They will be able to consider lamp placement, amount of airflow and the design of certain fixtures to ensure the quality of your indoor air system.

Portable Air Cleaners

There is no clear evidence that making use of portable air cleaners will reduce the risk of contracting COVID-19. However, HEPA filters can have a positive effect depending on the size of your residential property and other factors.


Final Take

The COVID-19 pandemic is well and fully in swing. However, there are steps that you can take to break the chain and ensure that you stay safe through it all. Firstly, you should know that the ideal place to get credible COVID-19 information are your local, regional, and national health authorities. Also, in addition to social distancing and hand washing, installing an indoor air filtration system in your home will go a long way in ensuring your health.
