How this is calculated
- ENERGY STAR lists the power this model draws but no yearly figure. We estimate the annual energy use ourselves, assuming 2 hours a day at its rated airflow, every day of the year. Your use will differ, so treat the cost as a guide.
- Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
- Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
- We do not estimate watts or hourly cost: the source data does not include them.
How it compares
Among 25 ENERGY STAR certified in-line (single-port) models with a similar airflow (135 to 225 CFM), this one ranks 16th lowest in annual energy use.

Frequently asked questions
How much electricity does the Ortech OIF5-190 use?
ENERGY STAR lists the power this model draws but no yearly figure, so we estimate about 26.8 kWh per year, assuming 2 hours a day at its rated airflow, every day of the year. Your use will differ with how long the fan runs; some homes run a bathroom fan only for a few minutes, others around the clock.
How much does it cost to run?
At statewide average residential prices, the listed annual use costs about $3.41 in Nevada and $12.64 in Hawaii (EIA, 2026-08). Your own utility rate may be different; enter it in the calculator.
How does the Ortech OIF5-190 compare with similar models?
Among 25 ENERGY STAR certified in-line (single-port) models with a similar airflow, it ranks 16th lowest in annual energy use. Its 26.8 kWh per year is 12% above the median of 23.9 kWh.
How much air does it move?
ENERGY STAR lists 180 CFM at its first speed setting. Choose a fan whose airflow suits the room and the duct size.
What does CFM per watt mean?
It is the air moved per watt of power, so a higher number means more ventilation for the same electricity. This model is listed at 4.9 CFM/W.

Methodology and sources
Model data comes from the ENERGY STAR Certified Ventilating Fans dataset (EPA). Electricity prices are statewide average residential prices from the U.S. EIA, latest period August 2026. Values are stored locally and refreshed by scheduled imports. Missing values are left blank, never estimated.
