Reducing Allergens in the Office During Summer Months

allergens

Summer brings sunshine, longer days—and a surge in allergens that can impact employee health and productivity. Pollen, dust mites, mold spores, and other airborne irritants are at their peak during the warmer months. For commercial property managers, ignoring allergen control in office spaces isn’t just a health risk—it can lead to more sick days, lower tenant satisfaction, and even HVAC strain.

The good news? A well-executed cleaning strategy can significantly reduce allergens and create a healthier, more comfortable indoor environment for everyone.

Here’s what you need to know—and how to tackle allergens head-on.

Why Summer Allergens Are a Bigger Problem

During summer, the air is full of pollen from grasses, trees, and weeds. Increased humidity also encourages mold growth, both inside and outside. Add to that dust, pet dander (brought in on clothing), and office debris, and you have the perfect storm for allergy flare-ups.

In commercial office buildings, where air is recirculated and people are in close quarters, allergens can build up fast—especially if cleaning routines aren’t adapted for the season.

Signs Allergens Are Impacting Your Office

  • Frequent employee complaints about itchy eyes, sneezing, or headaches
  • Increased absenteeism due to respiratory issues or sinus infections
  • Noticeable dust buildup on surfaces or in vents
  • Musty odors, which can indicate mold or mildew
  • Visible patches of mold near vents, windows, or in restrooms

Even if your building looks clean, allergens may be lingering in carpets, upholstery, ductwork, and other hidden areas.

Smart Strategies to Reduce Office Allergens

1. Upgrade to High-Frequency Cleaning Services

Regular janitorial services may not be enough during the summer months. Increasing the frequency of deep cleaning for carpets, upholstered furniture, and common touchpoints will help eliminate built-up allergens.

What to Prioritize:

  • Carpets and rugs (vacuumed with HEPA filters)
  • Break rooms and kitchens (hotspots for mold and bacteria)
  • Restrooms (especially grout and tile where mold can grow)
  • HVAC vents, baseboards, and ceiling fans

Ultimate Cleaning Solutions can tailor a seasonal cleaning schedule to your building’s specific needs.

2. Use HEPA-Filtered Equipment

HEPA (High-Efficiency Particulate Air) vacuums trap particles as small as 0.3 microns—including pollen, mold spores, and dust mites. Traditional vacuums may stir allergens into the air rather than remove them.

Ask your cleaning provider if their equipment meets HEPA standards—and make it a requirement if it doesn’t.

3. Schedule Air Duct Cleaning

If your tenants are constantly sneezing or complaining about “stale air,” it could be coming from dirty air ducts. Dust, pollen, and mold spores settle in ductwork and get pushed back into the workspace every time the A/C kicks on.

Duct cleaning every few years (or more often in older buildings) can drastically improve indoor air quality and HVAC efficiency.

4. Control Humidity and Ventilation

Excess humidity creates the perfect environment for mold and mildew. Offices should maintain indoor humidity levels between 30% and 50%.

Tips:

  • Use dehumidifiers in high-humidity areas like basements or storage rooms
  • Ensure proper ventilation in restrooms, kitchens, and janitor closets
  • Fix any leaks or water stains immediately

5. Replace or Clean Air Filters Regularly

A clogged air filter in your HVAC system won’t trap allergens effectively. Replacing filters monthly—or at least quarterly—is essential during the summer allergy season.

For high-traffic buildings, consider upgrading to filters with a higher MERV (Minimum Efficiency Reporting Value) rating.

6. Promote a Fragrance-Free Office Policy

Many commercial cleaning products and air fresheners contain chemicals that can irritate allergies. Opt for fragrance-free, non-toxic cleaning agents to avoid triggering reactions.

Ultimate Cleaning Solutions uses green-certified products that are tough on dirt—but gentle on airways.
