Indoor Air Quality Is More Important Than Ever

Jul 1, 2020 4:38:18 PM / by RenovationsPlus


Whether continuing to shelter in place or starting to return to work, Americans are spending an average of 90% of their time indoors. Because of this, indoor air can be up to five times more polluted than outdoor air.1

No matter the size of your facility, you understand the importance of providing people with a healthy environment. Indoor air quality (IAQ) plays a significant role in reducing health risks and improving productivity for your team, and can positively affect the perception of your property. Follow the tips below to help create a clean, pollution-free environment.


The First Line of Air Defense

The first line of defense against poor indoor air quality is air filters. Regularly inspect and change your HVAC system’s air filters to help maintain good indoor air quality. In fact, change out air filters at least once every few months and once a month for best results and maximum HVAC efficiency.

The effectiveness of filters depends on the materials used to create them, so choose high-quality air filters that work well on all kinds of particulates and debris. For the most effectiveness, however, change your air filters regularly.


Like a Nicely Cooled Glove

Something you may not have ever considered is if the system you’re currently using is the right size for your facility. You may think that indoor air quality goes up with larger HVAC systems, however, that isn’t necessarily true.

A system that is too large for any given area can cool the air too quickly, which leaves air feeling damp. The extra humidity in that space then can cause a buildup of mold that can lower indoor air quality. You should try to keep the humidity level between 30 and 50 percent to prevent mold growth and allow your HVAC system to run efficiently.2


Breathe Easy

Take control of indoor air quality with air purifiers and HEPA filters. Germs, odors and particulates can be found almost everywhere in your facility, but they are kept in check with quality air purifiers. Many purifiers have a compact design, allowing them to fit in tight spaces where these enemies of clean breathing like to hide.

Also, a lot of purifiers include remote functionality for easy control of indoor air quality. Some even come with odor control features that help create a clean, fresh environment for everyone.

For an even higher level of indoor air quality, pair your air purifiers with HEPA air filters. High-efficiency particulate air (HEPA) filters can remove at least 99.97% of dust, pollen, mold, bacteria and other particulates up to 0.3 microns in size3. These efficient filters also are easy to replace and help with odor control.


More IAQ Solutions

In addition to the obvious IAQ remedies, such as HEPA air filters and HVAC units that are the right size, there are numerous other ways to help promote cleaner air in your facility. The best place to start is actually outside of your facility. By keeping entrances and solid-surface floors clean, you can prevent pesticides, dirt and other pollutants from being easily tracked inside your facility.

A floor mat at each entrance can also significantly minimize the amount of contaminants that make it inside of your property. Those contaminants that do make it inside can be quickly eliminated with regular mopping of hard surfaces with microfiber mops.

Don‘t forget about odor neutralizers as an addition to your regular cleaning program! Perfect for common areas and public restrooms, odor neutralizers strengthen the feeling of cleanliness on your property by providing fresh air that lasts.
