- Clinics/consulting rooms that don’t need the throughput of the 500 model
Key benefits
- H13 HEPA performance — medical-grade filtration for 0.3 µm particles (dust, pollen, mould spores, fine smoke). :contentReference[oaicite:1]{index=1}
- CADR 300 m³/h — sized for small-to-medium rooms and typical South African bedroom volumes. :contentReference[oaicite:2]{index=2}
- Smart & simple — particulate sensor, colour AQI ring, Auto mode, timer, child-lock, filter reminder. :contentReference[oaicite:3]{index=3}

- AFSA-listed range — GMC AP300 appears on the Allergy Foundation SA site. :contentReference[oaicite:5]{index=5}
Coverage & sizing (ACH made easy)
Use air changes per hour (ACH) to pick the right size:
- Room volume = length × width × height.
- Target ACH: 3–5 (general), 5–8 (allergies/smoke), 6–10 (clinical).
- Required CADR ≈ (Volume × ACH) ÷ 60.
Example: 4.5 × 3.5 × 2.6 m = 41 m³. For 5 ACH → (41 × 5) ÷ 60 ≈ 342 m³/h. One GMCAP300 (300 m³/h) gives ~4.4 ACH—ideal for bedrooms; use two units or step up for higher ACH.
Filtration system
The GMCAP300 is advertised with multi-stage filtration that includes Pre-filter, H13 HEPA, Activated Carbon, silver ion/anti-bacterial layer and ionizer (switchable). Some materials call this 6 stages; others list 8. We follow GMC’s documentation and note that stages can vary by batch. :contentReference[oaicite:6]{index=6}
Noise, placement & everyday use
At ~28 dB on low, it’s bedroom-friendly. Place 20–30 cm from walls with a clear intake path. Use Auto for daily use; boost to High during spikes (vacuuming, cooking, pollen days). :contentReference[oaicite:7]{index=7}

When to choose a different model
- You need ≥450 m³/h CADR for higher ACH in big rooms → consider the GMCAP500 or use two units. :contentReference[oaicite:9]{index=9}
- You have a very small room (≤20 m²) and want ultra-low noise → a 280–300 m³/h unit on low, or a smaller model, may suit better. :contentReference[oaicite:10]{index=10}
