The air inside your serviced apartment is likely two to five times more polluted than the street outside, and in some buildings more than a hundred times worse. That’s a striking number when you think about how much of an expat’s day happens indoors: the co-working desk, the hotel gym, the studio kitchen, the lobby you walk through twice a day.
For anyone signing a six-month lease in a new city, that changes what “a nice building” actually means. The finishes and the rooftop pool are easy to judge on a tour. What shapes how you feel every morning is harder to see, and it starts with how the building is cleaned.
Indoor Air Is the Story Nobody Puts in the Listing
Expat life tends to be an indoor life. You land in a new city, and for the first month you’re living between your apartment, your office, cafés, the mall, and the gym.
That gap widens in dense cities and in buildings sealed up tight for air conditioning, which describes most of the Singapore, Bangkok, Dubai, and Kuala Lumpur properties long-stay tenants gravitate toward.
Dust, cleaning residues, cooking particulates, and off-gassing from furniture all pile up in a closed unit. A building that vacuums well, ventilates properly, and picks cleaning products that don’t leave a chemical fog behind will feel different to live in. You may not be able to name why. You’ll sleep better and cough less.
The Cleaning Program Behind the Lobby You Like
The lobby, the corridors, the gym mats, the elevator buttons: someone is cleaning all of that on a schedule, with specific products and specific equipment. That program is the single biggest lever a building has on the air its residents breathe. And there’s real evidence it matters.
The takeaway for a tenant is simple: how a place is cleaned isn’t a cosmetic detail. It’s an environmental one.
Questions Worth Asking Before You Sign
Most tenants ask about Wi-Fi, laundry, and gym hours. Few ask how the building is actually maintained. A handful of pointed questions during a tour will tell you more about your next year of daily life than any brochure.
- Who cleans the common areas. In-house staff, or a contracted commercial cleaning company? Contracted teams often bring more consistent training and equipment; in-house teams can be more responsive. Neither is automatically better. Ask which it is and how long the arrangement has been in place.
- What products they use. If the answer is a blank stare, that’s your answer. Buildings that have thought about indoor air can name their product lines and often talk about low-VOC or fragrance-free options.
- How often HVAC filters are changed. A modern condo in a humid climate should be on a documented schedule, not “when we notice.” Ask to see it.
- Whether cleaning happens during peak hours. Vacuuming the corridor at 3 p.m. sends dust straight into units with open doors. Overnight or off-peak cleaning is a sign the building thinks about residents, not just optics.
- How the gym and pool areas are handled. Damp, high-touch spaces are where cleaning shortcuts show up first. If it smells strongly of bleach every time you walk in, that’s not clean, that’s masked.
Why Property Managers Are Getting Choosier About Vendors
On the operator side, the math around cleaning has shifted. Building owners running portfolios across cities have started treating janitorial not as a line-item cost but as part of the tenant experience, on par with security and concierge.
A well-run cleaning program lowers complaints, keeps finishes from wearing out early, and shows up in retention data at the end of the year.
That’s why serious operators hire specialized facility services firms that can standardize how a lobby in one city gets cleaned versus a lobby in another, with documented processes, trained crews, and the equipment to match. For a long-stay tenant, the practical benefit is predictability. The building you liked in month one still looks and feels the same in month nine.
What You Can Control Inside Your Own Unit
Even in a well-run building, a chunk of your indoor air quality comes down to you. Serviced apartments give you less control than a house, but not zero.
- Open the windows. Ten minutes of cross-ventilation a day, when outdoor air quality allows, resets a sealed unit more than any gadget.
- Skip the heavy air fresheners. Plug-ins and scented sprays add VOCs rather than remove them. If a room smells stale, the fix is airflow, not perfume.
- Wipe with microfiber and water. For most surfaces, that’s enough. Reserve disinfectants for genuinely high-touch, high-risk spots.
- Look up before you unpack. Air-conditioning grilles collect dust fast in tropical climates. If yours are gray, request a clean before you move in and put it in writing.
None of this is glamorous, and none of it will show up on a listing photo. But the buildings that get it right are the ones expats renew in year after year. That’s usually a better signal than the rooftop pool.
