In modern Edmonton office towers, windows are sealed, and the indoor environment relies entirely on the building's HVAC system. When employees complain about allergies, dust, or "stale air," facility managers often look to their HVAC filters first. However, the root cause is frequently walking right through the front door every night: the commercial cleaning crew's vacuum cleaner.
The Problem with Standard Commercial Vacuums
Many cut-rate cleaning companies use standard, single-stage or dual-stage commercial vacuums. While these machines have strong suction to pick up visible dirt and paper clips, their filtration systems are highly porous. They act as "dust pumps." They suck up dust mites, pollen, dead skin cells, and bacteria from the carpet, only to immediately exhaust the microscopic particulates back into the air.
These particulates remain suspended in the air for hours. When your employees arrive the next morning, they breathe them in, leading to increased absenteeism due to respiratory irritation and illness.
The HEPA Difference
HEPA stands for High-Efficiency Particulate Air. By definition, a true HEPA filter must capture 99.97% of particles that are 0.3 microns in size. To put that in perspective, a human hair is about 70 microns thick.
At ArcticFresh Commercial, we strictly forbid the use of non-HEPA vacuums in our clients' facilities. Our entire fleet consists of four-stage HEPA filtration units. When our crews vacuum a corporate office or medical clinic, the air exhausted from the machine is actually cleaner than the ambient air in the room.
HVAC Efficiency and Cost Savings
Improving Indoor Air Quality (IAQ) isn't just about employee health; it's about operational efficiency. When your cleaning vendor uses HEPA vacuums, significantly less airborne dust is pulled into your building's HVAC returns. This means your expensive HVAC filters last longer, and the system doesn't have to work as hard, resulting in lower energy costs and reduced mechanical wear and tear.
If you aren't sure what type of equipment your current cleaning provider is using, it's time to ask for an equipment audit.
