# MATULSA KE01 Register Booster Fan, 4 x 12 in

The MATULSA KE01 register booster fan is designed for 4 x 12-inch register openings and adds remote control, a thermal probe and ten speed settings. Its thermostat modes are described as responding to hot or cold airflow thresholds, so it suits rooms where airflow from an existing vent needs a boost rather than standalone room ventilation.

## At a glance

- Ten speed settings and push-button or remote control are listed.
- The product description gives a vent-opening fit range of 11.65–12 inches long and 3.93–4.5 inches wide. Measure the opening, not just the register cover.

## Pros

- Remote operation and ten listed speeds offer multiple control options.
- Hot- and cold-triggered operation is described for heating and cooling airflow.
- The stated opening range helps buyers compare the product with a measured register opening.

## Cons

## Before you buy

- The listing is inconsistent about dimensions: the product is presented as 4 in x 12 in and the feature text gives a fitting range of 11.65–12 inches by 3.93–4.5 inches, while the separate product-dimensions field says 1"D x 1"W x 1"H.

The description also calls it a register booster for floor and wall vents, while mounting details additionally list ceiling mounting, which is not explained.

- Positive themes: Customers appreciate installation and fit.
- Mixed feedback: Noise opinions vary, with some describing it as quiet and others finding it loud.
- Mixed feedback: Perceived value for money is mixed.
