SuntellWhole-home ventilation

Fresh, filtered air for the whole home. No roof cuts, no ductwork.

Suntell is an attic-mounted positive-pressure ventilation unit: it draws outdoor air through the home's existing soffit vents, filters it, and pushes it gently into the living space so stale air leaves on its own.

How positive-pressure ventilation works

A supply fan pushes filtered outdoor air into the home, which holds the house at a slight positive pressure. Stale air leaves through the home's existing gaps and exhaust ducts instead of being drawn in through them unfiltered.

Cross-section of a home: the Suntell unit sits in the attic near the soffit vents, draws outdoor air through the soffit and its MERV-8 filter, pushes filtered air into the living space, and stale air leaves through existing gaps and exhaust ducts 1 2 3 4 Attic No roof penetration, no ductwork Living space Existing exhaust Window gaps Door undercut Outdoor air Soffit vent Filtered supply air Stale air leaving the home
  1. Unit mounts in the attic

    Near the existing soffit vents. No structural modifications, no roof cut, no duct runs.

  2. Plugs into a standard 120 V outlet

    The unit draws 27 W and the manufacturer says no special electrical work is needed. Where the attic has no outlet, adding one is a licensed electrician's job under local code (our guidance, not a manufacturer requirement).

  3. Outdoor air enters through the soffit vents

    The unit pulls air from under the eaves and passes it through its built-in MERV-8 filter.

  4. Filtered air pushes into the living space

    The home sits at a slight positive pressure, so stale air leaves through existing gaps and exhaust ducts instead of being drawn in unfiltered. The connection from the unit into the living space is drawn schematically; the manufacturer's documentation does not detail it.

Original schematic drawn for this site, not to scale. Steps 1 to 4 follow the manufacturer's operating description.

Built for the people who install it

Pepnice designed Suntell around the problems builders run into with mechanical ventilation: roof penetrations that become leak claims, duct runs that need an HVAC sub, bulky equipment competing for attic space, and noise complaints after move-in.

  • No roof penetration: intake is through the existing soffit vents
  • No ductwork to run; the unit mounts in the attic with basic hand tools
  • Standard 120 V outlet, 27 W
  • Built-in MERV-8 filter on the incoming air
  • 33 dB noise level, EC motor rated for 50,000 hours
  • Pepnice states it meets ASHRAE 62.2 and IRC M1505

Product and size

One model is documented today, the PIV 100NA at 95 CFM. Check it against your home's required whole-house ventilation rate.

Enter the home's floor area and bedroom count. The helper uses the IRC M1505.4.3 continuous whole-house rate: 0.01 x floor area + 7.5 x (bedrooms + 1), in CFM.
