Air purifiers for tenants in Singapore rental units
Air purification is usually a tenant's own arrangement in a Singapore rental unit. See what to check on move-in and when to size the space.
Key takeaways
- Air purification is rarely part of a Singapore rental listing, unlike the aircon units themselves
- Check whether the aircon only recirculates indoor air before deciding what the unit needs
- Size a purifier to your bedroom or main living area, not the whole floor plan at once
- A settling-in period of a few weeks often reveals more than a guess made on move-in day
What's typically included in a Singapore rental listing versus not
Tenancy listings across HDB, condo and landed rentals usually cover the fixed items: split-unit aircon, a water heater, sometimes basic furnishing if the unit is marketed as furnished or partly furnished. Aircon servicing is often written into the tenancy agreement, with responsibility split between landlord and tenant depending on the clause.
Air purification almost never appears on that list. It sits in the same category as a kettle, a fan or a rice cooker: a portable appliance the household brings in, not a fixture the landlord maintains. If a listing does mention one, treat it as a bonus rather than something to expect as standard.
It is worth asking the agent directly before signing, since terms vary listing to listing and some landlords do leave appliances behind from a previous tenancy. Get anything left behind noted in the inventory list so there is no dispute at handover.
Why air purification is usually the tenant's own arrangement
The reasoning is mostly practical. What a household needs from filtered air depends on who lives there: a baby in the room, someone with allergic rhinitis, a shedding pet, or none of the above. A landlord furnishing a unit for the general rental market has no way to anticipate that, and buying a purifier that then sits unused between tenancies is a poor use of their budget.
A purifier is also portable in a way fixed aircon is not. You can take it with you at the end of the lease, service it on your own schedule, and size it to whichever room matters most rather than the whole unit. That flexibility is exactly why it makes more sense as a tenant's own purchase or rental than a landlord-supplied fixture.
If you are choosing between buying outright and a flexible rental plan, our guide to renting versus buying an air purifier walks through both routes.
Checking the unit's aircon and ventilation setup on move-in
Before deciding what to bring, spend your first few days checking how the unit actually breathes. Many HDB and condo bedrooms rely on split-unit aircon that only recirculates indoor air, with no dedicated fresh air intake, so odours and stuffiness can build up over a closed-door night.
Check whether windows open properly and how much outdoor noise or haze exposure that lets in, since some tenants keep windows shut through humid or hazy stretches and rely entirely on the aircon. Look for any musty smell in wardrobes or bathroom-adjacent walls, a common sign of trapped humidity in older units.
Ask the outgoing tenant or agent when the aircon was last serviced. A unit overdue for a chemical wash recirculates dust and mould spores more than a freshly serviced one, which changes how hard a purifier has to work in that room.
Sizing before or shortly after moving in
You do not need to wait until you are fully settled to size a purifier, but you do need real measurements rather than a guess from the listing photos. The formula is straightforward: required clean-air delivery rate in cubic metres per hour equals floor area in square metres multiplied by ceiling height in metres, multiplied by your target air changes per hour. Singapore homes are generally recommended three to four air changes per hour.
If the tenancy agreement includes a floor plan with room dimensions, use that. Otherwise, a tape measure on move-in day takes a few minutes per room. Run the numbers through our air purifier size calculator, which maps the result to the right AIRE model for that room.
Size room by room rather than for the whole unit. A single oversized unit in the living room rarely does much for a closed bedroom door at night.
Getting a survey once you've settled into the unit
Living in a place for a few weeks tends to surface things a first walkthrough misses: a bedroom that feels stuffier than expected, a smell that appears after rain, a room that never quite airs out. That is a reasonable point to get a proper site assessment rather than relying on the calculator alone.
AIRE offers a free room-by-room Air Report with zero upfront cost, which covers the same ground as a self-measured calculation but with someone walking through the actual space with you. It is a sensible step once you have lived in the unit long enough to know which rooms genuinely need attention, rather than sizing every room on day one.
Whether you end up buying or renting, starting from an accurate room-by-room picture avoids paying for more coverage than the unit needs.

Frequently asked
Is air purification typically included in a Singapore rental listing?
No, it is rarely included. Most listings cover fixed items like aircon and a water heater, while an air purifier is treated as a portable appliance the tenant brings themselves. It is always worth confirming with the agent before signing, since a small number of landlords do leave one behind.
What should a new tenant check about aircon and ventilation on move-in?
Check whether the aircon only recirculates indoor air with no fresh air intake, test that windows open properly, and look for any musty smell in wardrobes or bathroom-adjacent walls. Ask when the aircon was last serviced, since an overdue unit recirculates more dust and mould spores into the room.
Should sizing happen before or after moving in?
You can start with rough measurements from the tenancy floor plan before moving in, but a tape measure on move-in day gives more accurate figures for the calculator. Many tenants then follow up with a proper site assessment a few weeks in, once they know which rooms genuinely feel stuffy or humid.
