10 field-tested tips
- 1HEPA alone doesn't remove gaseous odor — pair with carbon or PCO.
- 2PECO / PCO units address VOCs and some biologicals; sized correctly for room volume.
- 3Whole-building bipolar ionization is oversold — verify third-party data before installing.
- 4For hotel guestrooms, add HEPA + carbon units in premium suites.
- 5Ozone generators only in unoccupied spaces; ozone at occupied-space levels doesn't remove odor safely.
- 6UV-C in HVAC coils prevents 'dirty sock' bio-growth on cold coils.
- 7Bipolar-ionization retrofit only after independent lab validation.
- 8Portable air scrubbers are essential for smoke, mold, and remediation events.
- 9Refresh carbon media annually — saturated carbon releases what it captured.
- 10Match CADR to room volume; underpowered units are placebos.
Why it matters
An air cleaner can run without improving conditions where complaints occur. Furniture can block the intake, discharge air can return directly to the unit, and open doors can bring contaminants from adjacent spaces. Filter fit matters too: gaps around the frame let untreated air bypass the media. Treat placement, airflow and maintenance access as part of the installation.
Practical steps
Check where complaints occur and whether they coincide with cleaning, deliveries or HVAC operation. Keep intakes and outlets clear, and avoid placing units behind furniture or beneath enclosed counters. Confirm that replacement filters match the equipment specifications and seat tightly against their seals. Before adding filtration to an air handler, have the available fan capacity and added pressure drop checked. Inspect prefilters for loading and carbon media for moisture exposure. Record filter changes, operating settings and complaint locations so staff can distinguish equipment problems from a recurring source. Keep outdoor-air ventilation operating as designed.
When to call a professional
Bring in an HVAC professional if added filtration reduces supply airflow, creates objectionable noise or leaves rooms stuffy. Persistent odors moving between rooms need an airflow and pressure investigation, not another portable unit. Suspected sewer gas requires urgent source investigation rather than a filtration trial.
