VENTS-US Freshbox 100 ERV Wi-Fi Single-Room Energy Recovery Ventilator (ERV) 59 CFM

VENTS-US Freshbox 100 ERV Wi-Fi Single-Room Energy Recovery Ventilator (ERV) 59 CFM

The VENTS-US Freshbox 100 ERV Wi-Fi from HVACDirect.com is a single-room energy recovery ventilator that brings in fresh, filtered outdoor air while sending stale indoor air out. It mounts on an exterior wall and vents straight outside, so there's no central ductwork to run. That makes it a good fit for bedrooms, apartments, condos, home offices, and small commercial spaces, especially in retrofits where adding ducts isn't practical.

Inside, a counterflow core with an enthalpy membrane passes both heat and moisture between the two airstreams without mixing them. In winter, fresh air comes in pre-warmed and holds onto some indoor humidity, so rooms feel less dry. In summer, extra heat and humidity get sent back outside before they reach the room, easing the load on your AC. Heat recovery runs as high as 90% on low speed, and the unit moves 18, 35, or 59 CFM across three fan speeds.

Key Features

• Energy Recovery Ventilation: Enthalpy membrane core transfers both heat and moisture between airstreams to cut heating and cooling losses.
• Airflow up to 59 CFM: Three fan speeds (18, 35, and 59 CFM) let you match airflow to the room.
• Up to 90% Heat Recovery: Keeps most of the heat you've already paid for inside the room.
• Year-Round Humidity Balance: Helps keep rooms from drying out in winter and getting muggy in summer.
• Low-Energy EC Fans: Draws only 20 to 53 watts on a standard 120V supply.
• Quiet Operation: Runs as low as 13 dBA at 10 feet on low speed.
• Two-Stage Filtration: MERV 8 and MERV 14 filters clean incoming air, with optional MERV 14 carbon or HEPA filter upgrades.
• Auto-Closing Shutters: Louvers close when the unit is off to block drafts and outdoor air.
• Frost Protection: A temperature sensor pauses the supply fan when the core starts to ice, then resumes normal operation once it clears.

Controls and Installation

• Built-In Control Panel: Change speeds and settings right at the unit.
• Wi-Fi Smartphone Control: Manage speed, timers, and a weekly schedule from an Android or iOS device.
• Filter Reminders: The unit lets you know when it's time to clean or replace the filters.
