MIA-AHE25JDB Residential H13 HEPA Energy Recovery Ventilator

米亚家用HEPA高效过滤全热交换器 — The AHE25JDB scales the H13 HEPA protection of the AHE15JDB up to 250 m³/h for larger apartments, covering 100–200 m² at ventilation rates sufficient for multi-bedroom households. Dual PSY polymer enthalpy cores maintain 92% total energy recovery, while the built-in H13 HEPA cassette captures 99.97% of particles at 0.3 µm — removing PM2.5, fine pollen, mould spores, and sub-micron biological aerosols from every cubic metre of fresh air delivered into the home. The definitive choice for allergy sufferers, families with young children, and any project where indoor air quality is held to medical-grade standards.

Key Features

Technical Highlights

The AHE25JDB combines the 250 m³/h capacity of the proven AHE25 platform with the highest available mechanical filtration grade — H13 HEPA — allowing larger homes and households with serious air quality requirements to achieve certified clean air without compromising on flow rate or energy recovery.

H13 HEPA Filter — 99.97% at 0.3 µm (PM0.3)

The built-in H13 HEPA cassette (EN 1822 certified) captures 99.97% of all airborne particles at the most penetrating particle size of 0.3 µm. At this grade, the filter is effective against fine PM2.5 dust, pollen (including fragmentary sub-5 µm particles), mould spores, pet dander, tobacco smoke, diesel soot, and airborne bacteria. Unlike ESP filtration which can produce trace ozone as a by-product of the corona discharge process, H13 HEPA is entirely passive — no emissions, no ionisation, and no ozone. Differential pressure indicator signals cassette saturation for timely replacement — typically annually in moderate environments.

Dual PSY Polymer Enthalpy Cores

Two washable PSY polymer cross-flow enthalpy cores recover both sensible heat and latent moisture at 92% total efficiency — identical to the NB and GLB variants at 250 m³/h. The polymer matrix transfers water vapour from the exhaust air stream to the incoming filtered fresh air, preventing winter desiccation even in cold continental climates. The enthalpy core is physically separate from the HEPA cassette — maintaining the hygroscopic exchange function regardless of HEPA cassette saturation state. Cores clean under running water every 3–6 months.

BLDC Fan 70W for allergy and medical grade

70W BLDC Fan — Allergy & Medical-Grade Performance

The 70W DC brushless centrifugal fan is rated to maintain 250 m³/h at the additional static pressure imposed by the H13 HEPA cassette — ensuring rated airflow is delivered even as the filter accumulates loading. Minimum speed produces 25 dB(A) for unobtrusive bedroom operation. The 986.5 × 641 × 228.8 mm body dimension is identical to the AHE25NB and AHE25GLB — allowing direct substitution within the same installation space when upgrading to HEPA filtration. Ø150 mm duct connections support the same multi-room distribution network designs as other AHE25 variants.

Applications

The AHE25JDB addresses scenarios where the AHE15JDB's 150 m³/h capacity is insufficient, and where ESP (GLB) filtration does not meet the requirement for certified mechanical particle capture without ionisation by-products.

Multi-Bedroom Apartments — Allergy Households

For 2–3 bedroom apartments where all occupants benefit from HEPA-grade air — not just a single room — the AHE25JDB covers the whole dwelling from a single ceiling-mounted unit. Delivers certified 99.97% particle removal at 250 m³/h across 4–8 supply outlets. Appropriate as the primary ventilation unit in homes where seasonal pollen, urban dust, or pet dander are chronic concerns.

Premium Residential — Air Quality as a Feature

Premium apartment developers and interior architects increasingly specify H13 HEPA ERV as a luxury wellness feature alongside air quality monitoring dashboards. The AHE25JDB installs flush in ceiling voids with no exposed equipment, delivers measurably superior air quality, and pairs with smart home platforms for real-time PM2.5 monitoring and automatic speed adjustment based on outdoor air quality data.

Post-Renovation & New Construction Off-Gassing

New and recently renovated apartments off-gas VOCs, formaldehyde, and fine dust from construction materials for months after completion. The AHE25JDB — optionally paired with an activated carbon stage — provides continuous HEPA-grade dilution of these contaminants while simultaneously recovering heating or cooling energy from exhaust air, dramatically reducing the energy cost of high ventilation rates during the off-gassing period.
