Upgrade Your Air Filters and Air Purifiers to Reduce Indoor Covid-19 Transmission

air purifier and air filter Covid-19

Can upgrading HVAC air filters protect against indoor Covid-19 airborne transmission? Can air purifiers reduce indoor Covid-19 airborne transmission? Yes, improving air ventilation in your home by upgrading HVAC air filters and air purifiers can reduce indoor Covid-19 airborne transmission. According to the CDC, Covid-19 can be spread indoors through airborne transmission. That means with poor indoor air ventilation at home, respiratory droplets of Covid-19 can build up in enclosed indoor space. These respiratory droplets will then infect people with Covid-19 via airborne transmission. You can improve indoor air ventilation at home by upgrading your home’s HVAC air filters and running air purifiers in heavy traffic rooms. Upgrading your HVAC air filters and air purifiers will reduce indoor Covid-19 airborne transmission.

How to Improve Ventilation at Home to Reduce Indoor Covid-19 Airborne Transmission?

Improving air ventilation at home is key to reducing indoor Covid-19 airborne transmission. There are 3 ways to improve indoor air ventilation at home to reduce Covid-19 airborne transmission. Three ways to improve indoor air ventilation at home is by 1.) Opening windows 2.) Upgrade your HVAC air filters to MERV 13 and 3.) Use HEPA air purifiers. Improving your home air ventilation can protect you and your family against Covid-19 airborne transmission.

Increase Ventilation by Opening Windows to Reduce Indoor Covid-19 Airborne Transmission

The easiest way to reduce indoor Covid-19 airborne transmission is by opening the windows at home. Opening windows will let fresh air into your home which will increase indoor air ventilation to protect you against Covid-19 airborne transmission. Opening windows is the easiest and the least expensive way to reduce indoor Covid-19 airborne transmission. However, it may not be practical and definitely not energy efficient to open your windows during the hot summer months when your A/C is running at full blast or to open your windows in the middle of winter (imagine the exorbitant gas bill!) Opening windows to increase indoor air ventilation is only realistic when the outside temperature is moderate.

Upgrade Your HVAC Air Filters to MERV 13 to Reduce Indoor Covid-19 Airborne Transmission

You should upgrade your HVAC air filters to protect you and your family against Covid-19 airborne transmission in indoor space. Improve air ventilation at home by upgrading your HVAC air filters to a higher MERV level. MERV stands for Minimum Efficiency Reporting Values. MERV is a rating on the air filter’s ability to capture particles. The MERV rating on air filters run on a scale of one to 16, with 16 being the best in filtering out small particles. However, don’t just go out and buy a higher MERV rating filter for your HVAC system. Make sure your HVAC system can handle the higher MERV rating. Most residential HVAC system will come with MERV-8 air filter by default. Check your HVAC manual or ask a HVAC professional to find out what type of air filter is installed in your HVAC system. The higher the MERV rating the better it is in capturing small particles.

Air Filters should be MERV 13 to Reduce Indoor Covid-19 Airborne Transmission

In order to filter out small particles such as Covid-19 viruses from indoor air, you need air filters with MERV 13 or higher. Air filters with lower than MERV 13 levels will not be able to capture small viral particles. You should check with your HVAC guy or HVAC manual to find out the highest rated air filter your HVAC can take (hopefully MERV 13 or higher!). Then upgrade your HVAC air filters to MERV 13 so your HVAC system can efficiently filter out Covid-19 viruses from your home’s indoor air.

What if your HVAC can’t handle MERV 13+ air filters or you don’t want to strain your HVAC system with a higher MERV air filter? An alternative to consider to improve indoor air ventilation at home to protect against Covid-19 airborne transmission is to install ALVI Air Filter Units. ALVI can be installed in your furnace, ceiling return/intake or floor return/intake. ALVI Air Filter Units will give you HEPA-class air quality and protects your home from harmful viruses, bacteria, dust, and mold. ALVI air filter units also lowers your home energy consumption by reducing strain on your HVAC system. Compared to standard HVAC air filters, your home will heat up and cool down faster with ALVI air filter units extending the life of your air handling system. Installing ALVI air filter units is a good option to increase indoor air ventilation at home to protect you and your family against Covid-19 airborne transmission.

Change Your MERV 13 Air Filters Every 90 Days to Reduce Indoor Covid-19 Airborne Transmission

It is important to change your MERV 13 air filters every 90 days to reduce indoor Covid-19 airborne transmission. Air filters remove impurities like pollen, dust, pet hair from the air in your home. If the MERV 13 air filter gets dirty, it will not work efficiently in filtering out small Covid-19 viral particles. In order to maintain good air quality in your home, at a minimum, you need to change your MERV 13 air filter every 90 days. You don’t need to hire a professional to change your MERV 13 air filters, it’s something you can do on your own without professional help. Most residential HVAC systems will have air filter slots which are easily accessible for air filter changes. Set an alert in your calendar to make sure you are changing your MERV 13 air filters every 90 days (or if you are like me, you can have your air filter store send you an alert when it’s time to reorder!). It’s especially important with the Covid-19 pandemic raging to have clean MERV 13 air filters in your home so you can prevent indoor Covid-19 airborne transmission.

Pro tip: You should always order double the number of air filters that you need so you always have an extra set handy when you do your air filter change every 90 days. Check out Airfilters.com, they carry a huge variety of HVAC air filters and will ship free to your home.

Air Purifiers to Reduce Indoor Covid-19 Airborne Transmission

With Covid-19 cases on the rise, you need to do everything you can to improve indoor air ventilation to prevent Covid-19 airborne transmission. There are 2 ways to improve air ventilation at home to prevent indoor Covid-19 airborne transmission. You can improve indoor air ventilation by 1.) using air purifiers and 2.) upgrading your HVAC air filters to MERV 13. The difference between air purifiers and HVAC air filters is that air purifiers are designed to filter the air in a single room while HVAC air filters are designed to filter air throughout your entire home. Using both air purifiers and HVAC air filters will help improve air ventilation at home to reduce the potential for indoor airborne transmission of COVID-19.

Think of air purifiers as a supplement to your whole house HVAC system. You can use air purifiers to help improve indoor air ventilation in certain interior rooms. For example, you can use air purifiers to improve air ventilation in rooms that have no windows like an inside hallway or interior bathroom. Sometimes in the winter, it can get stuffy because your HVAC fan is not constantly running. Air purifiers can help improve indoor air ventilation in stuffy rooms. And when its impractical to open windows due to rain, snow or extreme outside temperature, you can use air purifiers to increase indoor airflow at home. I always have an air purifier running in my bedroom, it improves the indoor air flow in my bedroom (and helps me sleep better!) Another advantage of having air purifiers is that it removes bad odors at home. Many air purifiers have carbon filters which is effective in filtering out bad odors. I always run an air purifier in the kitchen to remove odors from cooking. The air purifier is especially effective in removing food odors during the winter months when there is poor indoor air circulation and it’s too cold to open the windows.

HEPA Air Purifiers are Effective in Reducing Indoor Covid-19 Airborne Transmission

Don’t automatically assume that all air purifiers protect against indoor Covid-19 airborne transmission. You need air purifiers that can filter out Covid-19 virus. According to the EPA, in order to protect against indoor Covid-19 airborne transmission you need to make sure your air purifier meets at least one of these criteria 1.) your air purifier must be designated as High-Efficiency Particulate Air (HEPA), 2.) your air purifier is Clean Air Delivery Rate (CADR) rated or 3.) the manufacturer states that your air purifier will remove most particles in the size range below 1 um. You need air purifiers with HEPA filter that captures small particles as small as 0.3 microns to reduce indoor Covid-19 airborne transmission.

Air Purifiers that Reduce Indoor Covid-19 Airborne Transmission
