Free Tool to Measure the Air Changes Per Hour of Your Space
Use this free tool to determine the Air Changes Per Hour (ACH) of a room based on its dimensions and whether or not the air purifier you’re considering will clean the air properly.
According to researchers, poor ventilation plays a role in transmission of Covid-19, not to mention other serious respiratory illnesses. That’s why it’s so important to make sure you have clean indoor air. How?
A term you’ll see used is “ACH”, or air changes per hour. ACH is a measure of the air volume added to or removed from a space in one hour, divided by the volume of that space. The higher the ACH, the better chance you’re breathing good, clean air.
How can you ensure clean air indoors?
- INTRODUCE CLEAN AIR FROM THE OUTSIDE. This means opening doors or windows, or pulling clean outdoor air into a space via a fan or duct*.
*If the air outside isn’t clean — think “places with pollution” — make sure there’s a filter in front of that fan or inside your duct to capture pollutants before they’re breathed in. - CHOOSING FILTERS FOR YOUR HVAC SYSTEM THAT REMOVE VIRAL PARTICLES. MERV 13a or higher, HEPA or silver-ion treated filters should be considered & evaluated for effectiveness in your particular HVAC system.
- USING PORTABLE AIR PURIFIERS WITH HEPA FILTERS AND/OR UV-C LIGHTS. Make sure they’re sized to give you the right amount of clean air. Our tool can help.
