Choosing Air Purifiers for Singapore Childcare Centres
Fit one medical-grade H13 HEPA purifier per classroom — the Fillo Plus suits rooms up to 30 m² — and lease as a fleet with a free 30-day pilot.
Air Quality for Preschools: What Haze Guidance Actually Asks
Operators often ask us whether regulations require air purifiers in childcare centres. No rule names a specific purifier model or CADR figure. Singapore's haze advisories recommend staying indoors with windows closed and running an air purifier when air quality reaches unhealthy levels.
Singapore's haze advisories recommend staying indoors with windows closed and running an air purifier when air quality reaches unhealthy levels. That second half is the part a haze management plan on paper cannot deliver — a sealed classroom without filtration simply traps whatever is already in the air. A correctly sized purifier is what makes a closed-up classroom workable for a full day of indoor programmes, which is why we treat it as the practical backbone of haze season prep for preschools.
And haze is only the visible problem. Young children in close quarters share bugs readily, HFMD circulates through preschools every year, and newly renovated centres off-gas formaldehyde and VOCs from fresh fit-outs for months. Clean-air capacity earns its keep year-round, not just when the sky turns grey.
Sizing Each Classroom: Two Minutes of Maths
Public-health guidance since the pandemic (including the US CDC) recommends targeting at least 5 air changes per hour of clean air in occupied spaces. Preschool classrooms — high occupancy, small lungs, long hours — deserve that standard.
The formula: required CADR (m³/h) = floor area (m²) × ceiling height (m) × target air changes per hour.
- An 18 m² nap room with 2.8 m ceilings at 5 ACH needs 18 × 2.8 × 5 = 252 m³/h — a Fillo Plus (CADR 300) covers it with headroom.
- A 25 m² classroom needs 25 × 2.8 × 5 = 350 m³/h — a Fillo Plus delivers just over 4 ACH there, a solid everyday baseline; a Classic 400S (CADR 480) clears the full 5 ACH comfortably.
Walk each room with a measuring tape, or use our air purifier size calculator and we will map units to your floor plan for you. The one mistake we see constantly: a single undersized unit in the corner of a large room, working hard and achieving little.
Which Unit Goes Where in a Childcare Centre
We size per room rather than selling one model for everything. This is how the lineup maps onto a typical centre.
| Space | Typical size | Our pick | Why it fits |
|---|---|---|---|
| Nap room / infant room | Up to ~20 m² | Fillo Plus | CADR 300 m³/h gives 5+ ACH in small rooms; slim 244 mm cylinder tucks into a corner; under 53 dB even at full speed; built-in night light |
| Standard classroom | 20–30 m² | Fillo Plus or Classic 400S | Fillo Plus covers day-to-day use; step up to the Classic 400S where you want a full 5 ACH at the top of the range |
| Large classroom / multi-purpose room | 31–54 m² | Classic 400S | CADR 480 m³/h, 8 fan speeds from 30 dB, child lock, auto and sleep modes |
| Hall / indoor gym | 56–96 m² | Pro 800S | CADR 800 m³/h on castors — wheel it between assembly, gross-motor time and events; 26 dB sleep mode |
Every one of these runs H13 medical-grade HEPA as standard — no consumer-grade filters hiding in the smaller units.
Quiet for Naps, Safe Around Small Hands
Nap time is where many purifiers fail the preschool test. The Classic 400S spans 30–55 dB across its 8 speeds, the Pro 800S drops to 26 dB in sleep mode, and the Fillo Plus stays under 53 dB even flat out — so on a low setting, clean air keeps moving while the room stays sleep-quiet. The Fillo Plus's soft night light doubles as a nap-room comfort.
On safety, the details matter in a room full of curious three-year-olds:
- Child locks on the Classic 400S and Pro 800S stop small fingers changing settings or switching units off.
- Filters sit fully enclosed inside the housing — nothing exposed, nothing to pick at; adults swap them during servicing.
- UV-C operates inside a sealed chamber and does not reach occupants — the light sterilises air passing through the unit, never the room.
- Placement: keep units against a wall with clear airflow, away from cots and climbing furniture, cords secured out of reach.
Why We Fit Preschools with the Same Units as Clinics
The units we recommend for classrooms are the same ones we deploy in dental and specialist clinics — and they are already running in a student care centre and a confinement care centre, two settings with exactly the same brief: young or vulnerable occupants, long hours, zero tolerance for gimmicks.
H13 HEPA captures at least 99.95% of particles down to 0.1 micron. On top of that, AIRE pairs H13 filtration with active sterilisation — UV-C light plus copper-silver ion technology — which eliminated more than 99.99% of tested airborne pathogens (E. coli, Staphylococcus albus, Influenza A) within 60 minutes in chamber testing, versus roughly 4 hours 23 minutes for the same organisms to decay passively on a standard HEPA filter. In a preschool, that difference matters: trapped germs are neutralised rather than sitting live on the filter between cleaning cycles.
To be clear about what a purifier can and cannot do: it reduces the airborne load in a room and supports your hygiene routines — it does not replace handwashing or exclusion policies, and nothing prevents illness outright. We cover where purifiers fit into HFMD-season hygiene for childcare centres separately. Our range carries FDA Class 2 medical device listing, CE, RoHS, ISO 9001 and ISO 14001 — paperwork worth keeping on file for parent queries and licensing reviews.
Equipping One Centre — or a Whole Chain — Without Capex
A centre with six classrooms, a nap room and a hall needs eight units. For a chain, multiply that across every branch — as a purchase, that is a capex line most operators would rather not fight for.
This is why we recommend flexible rental for childcare operators. Flexible rental turns clean air into a predictable monthly operating cost, keeps every centre on identical, current equipment, and scales unit by unit as enrolment grows or new branches open. We break down the numbers in our guide to renting versus buying.
And you do not have to take our word for any of it. Our free 30-day pilot puts a unit in one classroom at zero upfront cost — let your principal, teachers and parents live with it through real school days, then buy, rent or return. We are a Singapore brand based at Victory Centre in Geylang, so support and filter servicing come from a local team, not an overseas distributor.
Frequently asked
Does ECDA require childcare centres in Singapore to have air purifiers?
No regulation we know of mandates a specific purifier. Singapore's haze advisories recommend staying indoors with windows closed and running an air purifier when air quality reaches unhealthy levels. Singapore's haze advisories recommend staying indoors with windows closed and running an air purifier when air quality reaches unhealthy levels, so most operators treat purifiers as the practical way to make that guidance work in a sealed classroom.
How many air purifiers does a childcare centre need?
One correctly sized unit per occupied room — each classroom, each nap room, plus a larger unit for the hall. Size with required CADR = floor area × ceiling height × target air changes per hour, aiming for at least 5 air changes per hour. A typical classroom takes a Fillo Plus or Classic 400S; halls need the Pro 800S.
Will an air purifier stop HFMD outbreaks in our centre?
No purifier prevents illness, and HFMD spreads readily among young children largely through close contact and shared surfaces — so handwashing, toy cleaning and exclusion policies remain your first line. A medical-grade purifier reduces the airborne load in the room and supports those measures rather than replacing them.
Are these purifiers quiet enough to run during nap time?
Yes, on lower settings. The Classic 400S runs from 30 dB across 8 speeds, the Pro 800S has a 26 dB sleep mode, and the Fillo Plus stays under 53 dB even at full speed. Run a low speed during naps and the units fade into the background while air keeps circulating.
