Room-size worked example: keep the assumption visible
Suppose a sourcing brief describes a 12 m² bedroom with a 2.5 m ceiling. The room volume is 30 m³. If the buyer selects 5 air changes per hour as a comparison target, the clean-air requirement is 30 × 5 = 150 m³/h. This is a procurement example, not a medical recommendation, and the target should be changed when the room, ceiling or buyer requirement changes.
The same floor area is about 129 ft². AHAM’s public 2/3 sizing rule would call for a tobacco-smoke CADR of about 86 cfm, or approximately 146 m³/h, for a typical 8-foot ceiling. EPA likewise tells consumers to choose CADR for the room size and notes that reported CADR is typically measured at the highest speed. A sourcing team should therefore ask for the exact test scope and separately check clean-air delivery and sound at the sleep setting customers may actually use.
| RFQ field | Evidence to request for the quoted model |
|---|---|
| Room match | Room length, width and ceiling height; verified CADR and test speed; buyer-selected ACH or room-size method. |
| Sleep operation | Sound data by speed with test conditions, plus airflow or CADR at the mode used for the noise claim. |
| Controls | What child lock disables, display-light behavior, filter-cover access and settings after power interruption. |
| Filtration | Exact filter part number, filter test report when claimed, installed fit, replacement interval assumptions and supply plan. |
| Ozone and ionization | Technology declaration, on/off behavior, model-level emissions or exemption evidence and destination-market listing when required. |
| Claims and labels | Permitted wording, voltage and plug, manual language, packaging marks and current documents matched to the exact SKU. |
Sample acceptance test for a nursery-positioned SKU
- Match the sample to the quotation: record model code, filter code, voltage, plug, control-panel version and optional functions.
- Check both maximum and sleep settings: confirm available CADR or airflow evidence and noise evidence for the named operating mode.
- Exercise every control: verify what child lock disables, whether the display can dim, restart behavior after power loss and filter-reset logic.
- Inspect the air path: confirm inlet and outlet clearance, filter orientation, filter-cover access and whether the filter can be installed incorrectly.
- Review electronic functions: document whether ionization, UV or another active technology exists, whether it can be disabled and which evidence applies.
- Lock the service plan: approve the replacement filter SKU, packaging, order quantity, availability assumptions and customer instructions.
- Approve claims last: map every numerical, health, medical, ozone, filtration and certification statement to evidence for the exact configuration and market.
What public guidance does and does not prove
EPA says no air cleaner eliminates every indoor pollutant and treats air cleaning as a supplement to source control and ventilation. It also distinguishes particle filtration from gas removal and advises avoiding devices that intentionally produce ozone in occupied spaces. These principles support an RFQ checklist; they do not endorse LYL or any specific model.
For California, CARB states that covered portable indoor air cleaners must meet the state’s ozone and electrical-safety requirements. CARB also states that certification does not rate pollutant-removal effectiveness or “health safety.” A buyer must match the current public listing, brand and model instead of extending one certificate or executive order to an entire catalog.
LYL project boundary
LYL can shortlist available purifier models, prepare private-label packaging and identify which model-specific documents are available for review. A company credential, historical report, CARB entry or filter-media result does not automatically prove CADR, whole-unit filtration, noise, childproofing, medical use or market eligibility for every configuration. MOQ, samples, functions, evidence and delivery terms remain subject to the written quotation.

Baby Room Air Purifier OEM FAQ
How should a buyer size an air purifier for a baby room?
Record the room length, width and ceiling height, then compare the required clean airflow with verified model CADR at the speed customers will use. EPA and AHAM room-size guidance can provide a planning baseline, but it is not a medical recommendation and does not replace model-specific evidence.
Does a child-lock button make an air purifier childproof?
No. Child lock is a control feature, not proof that the complete product or room setup is childproof. Test what the lock disables, power-recovery behavior, filter-cover access, indicator lights, cable placement and the instructions for the exact sample.
Should a private-label page publish an exact sleep-mode noise value?
Only when the quoted model has evidence that identifies the operating mode and test conditions. Ask for sound data by speed and also confirm the clean-air delivery at the sleep setting; a low number without operating context is not enough.
Can a brand call a baby-room air purifier baby-safe or medical-grade?
Do not use those claims by default. Claim approval depends on the exact model, intended use, evidence and destination-market rules. CARB certification, for example, addresses California ozone and electrical-safety requirements and does not rate pollutant-removal effectiveness or health safety.
What evidence belongs in a baby-room air purifier RFQ?
Include room dimensions, target clean airflow, CADR test scope, sound by speed, control behavior, filter report and part number, ionization or ozone status, voltage and plug, destination documents, packaging claims, quantity and sample acceptance tests.
