Improved Indoor Air Quality Supports Your Successful Reopening

Jun 8, 2021 9:04:40 AM / by RenovationsPlus


As states begin to loosen regulations related to COVID-19 protocols, it becomes more important that your business is ready to reopen by offering healthy indoor spaces. According to OSHA, indoor air quality (IAQ) investigations have found that inadequate ventilation and contamination from interior and exterior sources were the main reasons for poor indoor air quality in commercial spaces. 1

Our renovation tips can help you optimize your IAQ and provide healthier air for those who live and work on your property. Set your facility apart from others and make your reopening a successful one.


Air Filters

Air filters are the first line of defense when it comes to keeping particulates and odors out of indoor air. However, their effectiveness depends on the quality of the materials and how often they’re changed.

For optimal efficiency, switch to filters with MERV ratings, which range from 1 to 16. The higher the MERV rating, the more efficiently the filter works. MERV 8 to MERV 13 air filters are ideal for residential applications.

Replacing your air filters regularly helps reduce airborne debris buildup and keeps the air in your facility clean. In fact, you should change air filters at least once every three months.

For best results, change them every month. Changing them monthly not only maximizes indoor air quality, it also maximizes the efficiency of your HVAC systems.


HVAC Systems

Another way to maximize the efficiency of your HVAC system for great IAQ is to ensure the units you’re using are the right size. A common misconception is that indoor air quality rises with larger HVAC systems, but this isn’t necessarily true. The square footage of the area to be cooled determines the size of the HVAC system you need.

A system that is too large for any given area can cool the air too quickly, leaving indoor air feeling damp and creating extra humidity that can cause a build-up of mold. Try to keep the humidity level between 30 and 50 percent to prevent mold growth and allow your HVAC system to run efficiently. 3


Air Purifiers

Germs, odors, and particulates can wreak havoc on IAQ. Install quality air purifiers, many of which feature remote functionality for easy control, to help create a healthier environment.

Pairing your air purifiers with high-efficiency particulate air (HEPA) cleaners, filters and accessories takes your indoor air quality to a new level. HEPA filters can remove at least 99.97% of dust, pollen, mold, bacteria, and other particulates up to 0.3 microns in size2.


Surfaces & Matting

You may not think about it, but clean surfaces and floor mats can also help improve indoor air quality. How? Keeping entrances and solid surfaces clean prevents pesticides, dirt, and other pollutants from negatively affecting indoor air quality in your facility.

Place floor mats at entrances to significantly minimize the amount of contaminants that make it inside your facility on the soles of shoes. Wipe countertops with microfiber cloths and clean floors with microfiber mops to capture dust, allergens, and other particles that were not stopped at the door by floor mats.


Clean Indoor Air Is Easier Than You Think
